EFI variables are not supported on this system.
No, if go into BIOS the option I have is to boot hdd or to USB drive if inserted.
When I had Linux Mint on sda1 everything was working fine.
The Manjaro GRUB showed at start up to select OS.
I replaced LM XFCE with PoP!OS and was able to boot into Pop!OS once with Manjaro GRUB after chroot and update GRUB.
Then I did a fresh install of Manjaro on sda2 (because it was bloated and slow) and now no Manjaro GRUB show when I start ancient laptop…
Both OS are the most recent ISO version.
I installed Pop!OS on sda1 and had a bugy slow manjaro on xfce. I updated Grub in chroot and at this time was able to boot into Pop!OS and Manjaro. Manjaro Grub showed Pop! Grub entry at start up allowing me to choose which OS to boot.
Then I did a clean install of Manjaro replacing the buggy one on sda2 with bootloader on sda and / (root) on sda2. Updated Grub again with chroot live usb.
After this Pop OS does not show anymore and when I start PC ti goes right into Manjaro. No GRUB shows…
I’m open to clean install both OS from scratch since both are clean installs. I just want to make sure I am able to choose which OS to boot to like before using Manjaro Grub .
