Then simply boot into live media and run Garuda Boot Manager and install Grub.
Thanks, will give it a try and revert
@Jonah in second pic
There is UEFI boot order
Go to OS boot manager by simply down arrow key and hit enter
Now see if your both OS entry is visible
If yes then you can reorder your boot entry by simply F6 and F5 and then for changes press F10
Hi Hall. No success. Once I hit enter, the UEFI Boot Order is activated but the only option available is to move the listed options (OS Boot Manager, USB Hard Drive, etc) up or down, no OS entry visible.
@Naman. Not good either, option to reinstall grub bootloader coming up, then install on MBR (not on root or ESP), then root location (btrfs) results in error
"Installing for i386-pc platform. grub-install: warning this GPT partition label contains no BIOS Boot Partition; embedding won't be possible. grub-install: error: filesystem 'btrfs' doesn't support blocklists,"
Fast boot needs to be off. That may not be the problem, but it is not helping. Did you see the dual boot tutorial? (Substitute Mint for windows) There needs to be a shared ESP (/boot/efi) FAT32 partition for grub to work with btrfs. This requires manual partitioning when installing Garuda. Mint's grub can't see a pure btrfs distro (and mint's grub won't boot Arch distros anyway.) Also, be aware that Mint will reset the boot order whenever its kernel is updated.
Boot to Garuda and provide info from terminal (input and output)
cat /sys/firmware/efi/fw_platform_size efibootmgr -v sudo os-prober inxi -Fxxxza
Your issue root cause is your HW/firmware (UEFI).
Your UEFI most probably includes the functionality to change installed OSes boot order, but you don't know how to do it.
If this function is absent, use
efibootmgr from garuda or Mint to change boot order.
If you set the correct boot order and your system changes it again, contact your vendor's support for help, or implement this workaround.
In any case, you should read the laptop User Manual!!!
Thank you for the dual boot tutorial redirect although I have no windows in my sys.
Thank you petsam for your assistance, noted the advise, and back to the drawing board
Btw, I used efibootmgr to change the boot order but (as expected) the system changed it again....now where is that manual
2 posts were split to a new topic: I also have a boot problem
You booted Garuda in BIOS/Legacy mode rather than UEFI mode.
This is probably why each bootloader can't see the other distro.
The solution is to boot in the same mode for all installed OS.
what is the difference between booting garuda linux zen fallback initamfs or garuda linux zen only can you help
For UEFI understanding which will help you troubleshoot, I advise reading this, it helped me immensely.
This is for the UEFI layer before grub.
Once you have this layer figured out and have all your os booting in uefi mode, then you can use the advice already given to use the grub from Garuda that will actually recognize the btrfs filesystem and see Garuda. Presumably it will also recognize the mint install too and add it to the grub list.
What has this got to do with this thread?
Thanks, trying to figure this out in my novelty.
Meantime, I notice Garuda 'sees' Mint's partition and lists it at startup (i.e. when login into Garuda and am even able to log into Mint via Garuda's grub) but Mint is totally blind to Garuda's existence.
From your input(s), I believe my problem is very small and I should figure my way out of this forest in due course.
Thanks again ALL for your tips @petsam @Naman @c00ter @jbMacAZ @hall
