how to fix boot device not found

Sometimes when you try to boot your computer, but it just won’t start up, or when the computer starts but shuts down after a few minutes, you may have a problem with your boot device. This is called a boot device not found. It can be caused by something like a corrupt hard drive, conflict with another program, or even malware. If you can’t get your computer to start up, it might be because of a problem with your boot device. Here are some tips to Fix Boot Device Not Found.

How To Fix Boot Device Not Found

1. If you have a boot device not found the problem, start by checking your hardware. If you have a new computer, make sure it has all of the hardware components that are necessary to run Windows. If you have an older computer, make sure it has all of the hardware components that are necessary to run Windows.

2. Next, you need to check your hard drive for errors and try booting from it. You can do this by going into Start > Settings > System and then clicking on “Advanced System Settings”. From there, click on “Startup” and then “Troubleshoot” from there select “Advanced Options” and then “Startup and Recovery” from there click on the option labeled “Safe Mode with Command Prompt”

3. Now Once your boot device is working properly, reboot your computer so Windows will load properly again. If this does not work for you, try starting in Safe Mode with Networking instead of Safe Mode with Command Prompt.

4. Another option is changing the boot order in BIOS (if your BIOS is supported). To access BIOS settings go here: Start > Settings > System > Advanced system settings > Advanced tab > (on most systems) press F2 at startup or during POST to enter the Setup Menu or F12 to enter the Advanced Boot Options menu or press the Delete key during POST if you are using a laptop without a keyboard as some laptops do not have a Delete key.

5. If you cannot access BIOS settings, you can use the following instructions to change the boot order in BIOS: Press the “Delete” key on your keyboard during startup to enter the Setup Menu or F12 to enter the Advanced Boot Options menu. Select “Boot” from the Boot Menu and make sure that your computer is set to boot from CD/DVD before the hard drive. Select “EFI” from the menu and select the “Boot from CD/DVD” option again, then press Enter on your keyboard. When prompted, select the USB stick containing Windows 8 installation files and follow the instructions that appear on your screen.

What Are the Causes of Boot Device Not Found?

1. BIOS settings in the BIOS are configured for booting from the hard drive.

2. Boot device does not have an operating system installed on it.

3. Boot device is damaged or corrupted and cannot be detected by Windows 8 installation files.

4. Boot device is not properly connected to your computer’s motherboard, it is not properly seated in its slot or it is damaged or loose.

5. Your computer’s motherboard has a problem that prevents the boot devices from being detected correctly by Windows 8 installation files, such as a bad IDE cable connection or a motherboard issue that causes the system to stop detecting boot devices correctly during startup and POST (power-on self-test).

6. Boot devices are configured incorrectly in BIOS settings on your motherboard, such as using “Legacy” (also known as “CSM”) boot mode instead of UEFI (Unified Extensible Firmware Interface) which is the default setting for most computers manufactured today that support UEFI and therefore cannot be used with Windows 8 installation files to boot from USB flash drives, CD/DVDs, etc.

7. USB stick/CD/DVD has been formatted with a file system incompatible with Windows 8 installation files (such as NTFS).

How To Fix Boot Device Not Found By Registry Keys

1. Press the “Windows” key to open the Start Menu and then click on “Run”.

2. Type Regedit in the “Open” field, and then click OK.

3. Locate and expand HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class \{4D36E965-E325-11CE-BFC1-08002BE10318} type BootEnabled into the right-hand panel of the registry editor (the first section) and then double click on it to modify its value to 1 .

4. Now locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control \Class \{4D36E965-E325-11CE-BFC1-08002BE10318}\0000 and delete all of its subkeys except for BootOrder .

5. Now repeat steps 4 and 5 for each other boot device that is not working properly on your computer, until you have modified all boot devices in Windows 8 from your computer’s BIOS settings that are not functioning properly with Windows 8 installation files to function properly with Windows 8 installation files.

6. Restart your computer, once it is powered off, press the “Delete” key during startup to enter Setup Menu or F12 to enter Advanced Options Menu or select Restart from the Power menu or reboot option in BIOS settings as appropriate depending on your computer’s motherboard.

7. Select “Windows” and then “Restart” in the Setup Menu or F12 to restart your computer.

8. When Windows 8 starts up, you should see a message saying that Windows is loading the boot files required to start up your computer and load Windows 8 installation files from your USB flash drive, CD/DVD, etc.

9. Follow the on-screen instructions to install Windows 8 installation files onto your computer’s hard drive and select an option that you would like to use for installing Windows 8 onto your computer’s hard drive (i.e., “Install now”, “Customize and select a partition” etc.) depending on your computer’s motherboard BIOS settings and hard drive configuration.

10. Once installation is finished, go ahead with the rest of this guide as usual by following Steps 1 through Step 7 listed above for how to fix boot devices not found by registry keys when you cannot boot from a USB flash drive, CD/DVD, etc.
