How to boot from hp pavilion disk. Convert to MBR without data loss. Basic BIOS settings for installing Windows. How to boot an HP Pavillion laptop from a flash drive or disk Hp pavilion how to boot from a disk

Over time, Windows inevitably becomes clogged, causing the laptop to run slower and slower. If no cleaning and optimization methods help, then there is only one solution left - a complete reinstallation of the system. And if earlier the system installation was performed from a special disk, now it is enough to create a bootable USB flash drive and start the laptop from it, and then calmly perform all the necessary steps. In this article we will look at how to boot from a flash drive on an HP laptop.

We also attach a short video instruction, which more clearly demonstrates the process of booting a computer from a USB drive.

It is not at all necessary to study numerous BIOS settings in order to change the boot priority from a disk connected to the laptop to a flash drive inserted into the USB port. If you need to boot from removable media only once, you can use a special boot menu called “Boot menu”.

To go to the boot menu on any laptop from HP, just press the F9 key when the first screen appears when the system starts. As soon as you click on this button, the download window will change to the Boot menu. The list will display all the drives connected to the laptop - all you have to do is select the flash drive from the list using the arrows on the keyboard, and then press the Enter key.

The next time you boot the computer (for example, after installing a new system or after carrying out all the necessary work), the start will be made from the hard drive - the Boot menu parameters are not accepted as standard and are used only for a one-time start of the computer.

Via BIOS

If the boot menu on your laptop does not open for some reason, or you need to boot from a flash drive several times in a row, you will have to change the boot priority in the BIOS. As a result of such actions, booting from the removable drive will continue until you return the boot parameters to their original state.

To change the boot priority via BIOS on an HP laptop, you need to follow these steps:

1. Insert the flash drive into any free USB port.
2. Restart the computer and press the F10 key while turning it on.
3. In the BIOS menu that opens, use the arrows on the keyboard to move to the “System Configuration” section.
4. Open the “Boot Order” tab and move the line from “USB Diskette on Key/USB Hard Disk” to the first position using the F5 and F6 keys (up and down, respectively)
5. Press F10 to save the changed settings, and then restart the laptop.

If everything is done correctly and the new settings are saved, then after rebooting the laptop will automatically start from the bootable USB flash drive - you can immediately begin diagnostics or reinstall the system.

If you want to boot from a flash drive in order to start reinstalling the system, but have not made the drive bootable, you will not be able to achieve a successful result. Let's briefly figure out how to correctly create a bootable USB flash drive using the Ultra ISO program as an example:

1. We download the utility from the official website - in the proposed list there is a version that has already been fully translated into Russian.
2. Launch the application with administrator rights and click on the “Open” button in the top panel.
3. In the explorer that opens, select the previously prepared Windows image.
4. We connect a flash drive to the laptop, which does not contain important data (everything will be deleted). In the “Startup” menu, click on “Burn image”. In the program window, click on “Format” (after selecting the flash drive in the list).
5. Click on the “Burn” button so that the utility writes the system image to the flash drive.

Now you can change the boot priority or use the Boot menu to start the PC from removable media and begin the OS reinstallation procedure.

Conclusion

If the keys presented in the article do not lead to opening the BIOS or Boot menu, Google your laptop model or find it through the manufacturer’s website - sometimes the combinations provided by the manufacturer change.

Many laptop users, including such a well-known manufacturer as, quite often complain that they cannot boot from a removable device in the form of the most ordinary flash drive containing an operating system installation distribution or specialized recovery tools, despite the fact that The flash drive is inserted into the appropriate port and seems to be detected by the laptop. The fact is that many current laptop models are equipped with built-in tools that allow you to access certain functions of the device, including changing the default boot parameters or even resetting the parameters to the factory state. Next, we suggest you see how to boot from a flash drive on an HP laptop. Despite the seemingly narrow focus, some points from the material proposed below will be useful for many other users who are faced with such problems.

Booting from a USB flash drive on an HP laptop: general principles

Like many other manufacturers, HP laptop developers decided to make it somewhat easier for their owners to access some important settings by building into most of the latest lines of such devices special menus that are not directly related to the primary or installed (installed) operating system. It is this menu that allows you to access both the BIOS parameters and the boot start menu with the selection of the required device to be used in each specific case. Despite such research, you shouldn’t discount installing Windows on an HP laptop from a flash drive using standard boot methods. Roughly speaking, the user has two options, but neither of them may work if some important conditions are not met and the necessary parameters are not set.

How to boot from a flash drive on an HP laptop using the standard built-in menu?

So, to begin with, let’s focus on the built-in tools, which can be found in the start menu, which in most cases is called up by pressing the Esc button immediately after turning on the laptop (this is directly evidenced by the appearance of the corresponding line on the screen).

Next, a list of all those actions that you can choose from appears. But in the context of booting, we are most interested in the start points with the ability to select a device (Boot Device Options - F9) without setting similar parameters in the primary system and the BIOS settings item (BIOS Setup - F10). Logging into the primary system may be required to change some settings that may block the use of removable drives to start from them, which makes it impossible to install another operating system other than the one you already have.

After pressing the F9 key, if the blocking options are not active, select your drive from the list, after which the HP Pavilion laptop will boot from the flash drive. But sometimes the start may not occur. Why then does the installed OS load, but the flash drive is ignored? It's all about some parameters of the primary system.

How to set the settings in the primary BIOS system?

The inability to use a flash drive as bootable media is explained by the fact that the primary system itself has a special lock called Secure Boot mode. By default, it can be in the active state.

Bypassing the blocking is quite simple. Enter the BIOS by pressing the F10 key, and then set the Disabled parameter for the specified mode, then exit the settings while saving the parameters (!), and when rebooting, use the start from removable media option again.

In some models, such actions are not enough. It also happens that to activate booting from a BIOS flash drive on an HP laptop after disabling Safe Start mode, confirmation is required, which many users ignore.

The system displays a line with a message stating that you need to enter the specified code and press the enter key!!! If you do not do this, booting from removable media will remain impossible.

What to do if the flash drive is not detected in the BIOS?

Now a few words about user complaints about the fact that the flash drive is not detected either in the BIOS or in the boot menu. Usually this situation is resolved quite simply, and not only on HP devices. Most users either do not know or forget that the flash drive must be inserted into the USB port before turning on the laptop. How to boot from a flash drive on an HP laptop in this case? Completely turn off the device using standard Windows tools, insert the media into the desired port, turn on the laptop and only after that perform boot manipulations (in theory, the device will be detected).

USB check

If for some reason the flash drive is still not detected, check the BIOS settings. This is the System Configuration section. Here the USB Boot item must be set to Enabled. If such loading is disabled, change the parameter, save the changes and try to start again.

Note: Please note that in some cases, the name of the flash drive in the primary system or in the boot menu may be preceded by the designation HDD, corresponding to the hard drive, after which the name of the removable device will be indicated. This is normal.

Properly creating bootable media

There is another problem regarding HP laptops. Installing another Windows OS from a flash drive may not start for the simple reason that the bootable media itself was created incorrectly (for example, it has an EFI bootloader, not an MBR, which is intended for devices with BIOS, not UEFI.

Try rewriting the system image for installation, for example, in the Rufus program, selecting a universal scheme as the bootloader, which can be used for both BIOS and UEFI.

If you use the UltraISO program, burn the image exclusively from the boot menu and under no circumstances change the USB-HDD+ recording method.

Options for starting from a removable device in the eighth and tenth versions of Windows

Now let's briefly look at how to boot from a flash drive on an HP laptop using standard Windows tools of versions 8 and 10. Go to the options menu, go to the recovery and security section, and in the recovery option select special boot options.

After this, after a couple of tens of seconds, a menu will appear in which you can select to start from removable media. Again, booting may not be possible if the security settings in the BIOS have not been changed as described above.

Disable disk encryption if it is active

Finally, another important problem associated with HP laptops. How to reinstall the system from a flash drive if the hard drive is locked in the form of the Bitlocker encryption tool (this, alas, also occurs).

In this case, you need to call the “Control Panel”, go to the encryption section, and then, if there is such an item, disable Bitlocker. If there is no such item, you can generate a code, enter it when using special boot options, and after unlocking the disk, install another OS instead of the existing one.

What to do if nothing helps?

If nothing works at all, try resetting to factory settings. This can be done either by a full reset in the latest versions of Windows itself, or by using the same “hard-wired” menu with the selection of the recovery partition (System Recovery - F11). If the malfunctions in the operation of the laptop or Windows are not so critical, you can perform diagnostics by using the corresponding item in the start menu (System Diagnostics - F2).

Epilogue

As you can see, there is nothing particularly difficult in choosing the correct configuration for using a flash drive as an external boot device. As for the most important conclusions and results, they are as follows:

• disable safe start mode in BIOS;
• be sure to confirm the change in parameters by entering the specified code;
• insert the flash drive into the desired port before turning on the laptop;
• Properly create bootable media for a specific primary system or disk partition;
• do not disdain boot tools for the latest modifications of Windows;
• unless absolutely necessary, do not replace the hard drive, and if you do, clone it if possible;
• Never, under any circumstances, experiment with deleting hidden hard drive partitions that may contain backup copies with factory settings and system utilities “built into” the laptop.

Finally, even if you follow the above rules, do not forget to periodically clean the system and promptly check it for viruses, since they can also play a fatal role in making it impossible to boot from a removable device.

So let's look at the option of booting from a flash drive with a UEFI boot loader on an HP 15-ac003ur laptop.

Let's move on to BIOS settings for booting from a flash drive without a UEFI bootloader on an HP 15-ac003ur laptop.

Let's go to “Startup menu”(as written above) and press the key "F10", or when turning on, immediately press the key "F10".
And the BIOS of the HP 15-ac003ur laptop appears in front of us. Here we see the main characteristics of the laptop, such as: the amount of installed RAM, processor, BIOS version and much more.

We need to disable, or rather transfer the BIOS operating mode from UEFI to Legacy.
Go to the tab “System Configuration” and option "Secure Boot" translate from "Enabled" V "Disabled".

Switch the “Legacy Support” option to “Enabled”.

After switching, a warning window will appear. We don't pay attention, we just confirm.

Having saved the settings, the laptop will reboot and a message will appear that the settings have been changed and if you want to boot with the parameters that were set, press 9365 and Enter.


P.S.: Your numbers will be different.

Enter the numbers that appear on your display and press “Enter”. After pressing “Enter”, immediately press “F9” to call the “Boot menu option”.


P.S.: If you were unable to launch the Boot menu option, then you will have to do all the settings again, this is the protection of the BIOS.
That's all the BIOS setup for booting from a flash drive on an HP 15-ac003ur laptop

Quite often, owners or users of laptops have to boot into the BIOS from a flash drive. Especially if the device does not have a CD/DVD drive, but you need to install a new operating system (OS) or install fresh drivers and anti-virus software. Therefore, in this article we will tell you in detail how to set boot from a flash drive in the BIOS on laptops from a variety of manufacturers (HP, msi, sony, dell, acer, etc.).

So, to enable booting from a flash drive in the bios on a laptop, you need to:

Do not forget that in the BIOS we can navigate through sections, tabs and lines only using the buttons on the keyboard. The mouse won't help you.

However, BIOS versions are different for all laptop manufacturers and models. Therefore, the algorithm of actions listed above is not suitable for all devices. For example, if you go to the BIOS and see a similar interface, then you have Award Bios.

Then it’s best to launch a bootable USB flash drive like this:

1. Go to the “Integrated Peripherals” section.
2. Approximately in the middle of the screen, use the arrows on the keyboard to find the “USB Controller” item.
3. Press Enter. In the window, select the “Enable” value.
4. Please note that the “USB Controller 2.0” line also contains “Enable”.
5. Press Esc. Let's leave this section. Then we go to “Advanced BIOS Features”. The name translates as additional or advanced settings. Here we need the “Hard Disk Boot Priority” item.
6. Let's go in and see what's in first place. It must be a flash drive, not a hard drive. Therefore, select the USB card and use the “+” button to lift it up.
7. Press Esc. Select the line “First Boot Device” and set the value to “USB-HDD” (or USB-FDD, if the first option fails to boot from a flash drive into the bios on the laptop).
8. Click Esc again. Select “Save & Exit Setup”, then press the Y key.

There are also other BIOS versions. These are both Phoenix-Award BIOS and AMI Bios. True, all of them are found only on old laptops with not the most “fresh” motherboards. How to configure boot from a flash drive for such devices? Everything is the same. Only the names of the sections and items in the BIOS menu differ. The algorithm of actions and settings is as similar as possible.

For reference! As we have already noted, in order to install booting from a flash drive in the BIOS, you need to “disable” the Secure Boot protocol. However, on many Lenovo laptops this is not enough. You may also need to enable compatibility mode. It is called differently. Therefore, look for CSM/CSM Boot, UEFI and Legacy OS, Legacy BIOS, Legacy Support, etc.

How to boot a laptop from a flash drive via UEFI?

Many modern computer devices (especially those with the latest versions of Windows) are equipped with a new boot interface. It's called UEFI. Working with this “option” of BIOS is a little easier. In addition, you can use the mouse here. However, despite the fact that the new interface is more understandable, not all users know how to work with it. Therefore, we will briefly describe the entire procedure.

For example, to boot from a flash drive on an HP laptop to UEFI, you need to:

1. When booting the device, press the ESC key several times. Then F10 to get into Bios Setup.
2. Now at the very bottom of the window find the Boot Priority section.
3. Just drag the icon in the form of a flash drive to the first place with your mouse.
4. Another option is to click on “Exit/Advanced mode”, then confirm the transition to advanced mode by selecting Advanced Mode. Next, complete the setup.

However, there are also quite a few versions of UEFI. There are also Russified versions. As a rule, it’s even easier to set boot from a flash drive here:

1. First you need to go to the “Download” section. Sometimes it is made in the form of a subsection. Then you should look for it in additional settings.
2. Just select “Disk loading order”.
3. In boot priority, put the flash drive first.
4. Press F10. Save changes, .

We will also tell you how to boot from a flash drive on devices with Gigabyte motherboards (they are preferred by many popular manufacturers - Acer, Lenovo, Samsung, etc.), on which UEFI BIOS is quite common.

1. Let's go to BIOS. You already know how this is done. The easiest way is to press “Delete”, “F2” or “Esc” at the initial boot stage.
2. Next, visit the “BIOS Features” tab.
3. At the very bottom of the window, click on “Hard Drive BBS Priorities”.
4. In the line “Boot Option 1” you need to put our flash drive instead of the hard drive. Therefore, in “Boot Option 2” the hard drive – HDD – will have to appear.
5. We save and exit.

How else can you boot from a flash drive on a laptop?

Through the computer's BIOS is not the only option. For example, it is possible to boot from a flash drive on an Asus, Toshiba, Samsung, etc. laptop and through a special boot menu. It's called the Boot Menu (by the way, it's also part of the BIOS). You can enter it during the initial loading phase. You just need to press Esc, F8, F11 or F12 quite often. Which key exactly depends on the manufacturer of the motherboard and the BIOS version used in it.

Once in the Boot Menu, you need to select and enable boot from a flash drive using the arrows on the keyboard. Then all you have to do is press Enter. Agree, it’s quite convenient and simple. However, it is not always possible to go to the boot menu. The fact is that on some laptop models the Boot Menu option is deactivated in the BIOS. Therefore, additional steps are required to enable it.

It is worth paying attention to one more point. The Boot Menu does not have a unified design. It can also be called differently: “MultiBoot Menu”, “BBS Popup”, “Boot Agent”, etc. However, any boot menu contains a list of devices from which booting can be done.

Possible problems

At first glance, booting a laptop from a flash drive is not difficult. However, some problems can always arise. Therefore, we decided to describe the most frequent of them. In addition, we will tell you how to eliminate them.

Please note that very old laptops may not be able to boot from USB flash drives at all. Then you need to either upgrade the device by installing a new motherboard and software, or think about purchasing a new computer.
