Switched from GRUB2 with EFI to Grub2 - no boot

English Install/Boot/Login

Hi, after a fresh install of Leap 15.5 on a HP 15-f271wm laptop, windows would try to repair itself every time the computer was started (I’m not dual booting, Leap is set to boot in EFI mode and secure boot is disabled). I had to go into boot options at startup and manually select opensuse for it to boot. After that I could log in and use the system as normal. I thought that windows trying to repair itself at every startup had something to do with EFI so I switched from GRUB2 with EFI to GRUB2 via Yast and surprise, the laptop doesn’t boot at all. If someone is available to provide some guidance on how to make this a bootable system again I would greatly appreciate it. I do have the installation media available. Thanks.

Plans to end support for 15.5 is just days away. I suggest to install 15.6 instead, and in EFI mode. If the same problem appears, it should be necessary to do very little to fix:

  1. delete the windows directory from the ESP
  2. if necessary (not enough via #1), use efibootmgr to delete windows from NVRAM. Alternatively, or in addition, eradicate any mention of windows as a selection in the UEFI BIOS boot section.

Alternatively, when installing 15.6, choose to either erase the whole disk and create a new ESP along with desired partitions for openSUSE, or just remove the current ESP and create a new one.

Hi

I agree with above post, and would like to add that it may need a tweak in the BIOS for AHCI mode perhaps.

It is also possible to have opensuse use EFI and MBR on the same drive, but don’t ask me how

Thank you both! I followed your suggestions, installed Leap 15.6, went through the Expert Partitioning during install setup and removed a couple of left over windows partitions like Microsoft Reserved Partition and a NTFS Partition labeled Windows RE Tools, formatted and mounted the EFI Partition and the system is booting as expected with no interference from anything windows related.
