Btrfs and learning...

Malcom: I’m really surprised that didn’t help!

Now:

# efibootmgr -v
BootCurrent: 0000
Timeout: 0 seconds
BootOrder: 0000
Boot0000* Notebook Hard Drive   BBS(HD,,0x0).......................................................................

Before my test reboot I executed the line you gave me…

efibootmgr -c -L “opensuse” -l “\EFI\opensuse\grubx64.efi”

And I saw that grubx64.efi was listed as #3 (with that SanDisk as #2). It changed to Notebook Hard Drive on reboot! (but with a couple of failed tries in between)

The failed tries:

  • tried setting EFI only in BIOS: “No Bootable Image - computer will shut down”
  • switched back to EFI + legacy
  • tried booting normally: “No operating system installed…”
  • tried BIOS F9 boot into “Notebook Hard Drive:” “No operating system installed”
  • BIOS F9 boot selecting “boot from EFI file” (as I have been doing) (it booted and here I am)

So, I’ll try executing the command again (not sure how to change the boot order with that efibootmgr command) but this time w/o changing bios at all.

# efibootmgr -c -L "opensuse" -l "\\EFI\\opensuse\\grubx64.efi"
BootCurrent: 0000

BootOrder: 0001,0000
Boot0000* Notebook Hard Drive
Boot0001* opensuse
# efibootmgr -v
BootCurrent: 0000
Timeout: 0 seconds
BootOrder: 0001,0000
