I was trying to dual boot Ubuntu 21.04 with windows 10 on my HP elitebook-folio-9480m.

I was following this tutorial to do the same. After creating the partitions for the installation process. The system gave me a "fatal error" about some issues regarding the boot partition as far as i remember.

However in another window it said that the installation was complete and I needed to restart the computer.

As I did so my pc would boot-up, show the "hp" logo then show a message in the top left saying "Reset System" and repeat.

I have tried and enter the boot menu but to no avail.

  • Right at the beginning of the video the person states "for Legacy BIOS users". That is unlikely to be the case for any computer with preinstalled Windows since a decade ago. The undisclosed fatal error is very likely the consequences of not having/not selecting the ESP (EFI System Partition). Please follow proper guides like this one https://askubuntu.com/questions/221835/how-do-i-install-ubuntu-alongside-a-pre-installed-windows-with-uefi instead of YT videos. – ChanganAuto Dec 05 '21 at 21:35

Try pressing Alt+F10 repeatedly to enter the advanced reboot screen of Windows. After that:

  1. enter into the BIOS
  2. change the bios order
  3. boot into Windows
  4. delete the partition with the corrupted OS
  5. remove grub.

  • Hello. You can not enter a computer BIOS through Windows. You enter BIOS by using the correct key on computer start. Your answer is completely wrong. – David Mar 28 '22 at 10:04
  • @David Technically, you can. Shift-clicking the Restart option in Windows 10 reboots into Windows's advanced startup settings, which has an option to reboot into UEFI/BIOS – Kurtoid Mar 29 '22 at 14:58

You can use Ventoy to locally boot Windows and Linux using F2 in the menu for searching the GRUB file and boot for booting in to Linux.
