"Reset System", bootloop after attempting to dual boot

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.

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.

you can use venoy -->() to local boot the windows and for the linux using f2 in the menu for searching the grub file and boot for booting in to linux
