I am in the Garuda live usb, trying to fix grub.
If I use the chroot tool, I get
ERROR: No Linux partitions detected!
If I use boot repair, I choose
Reinstall grub
ESP
Location: sda1 100M vfat
Root location: sda6 137.8G btrfs Garuda
And then I get:
Sorry, could not mount /boot/efi partition
Can you share the output of:
lsblk
sudo parted -l
l
sblk

What if you try the manual procedure:
sudo mkdir -p /mnt/broken
sudo mount /dev/sda6 /mnt/broken
sudo garuda-chroot /mnt/broken/@
Then into the chroot:
mount /dev/sda1 /boot/efi
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=garuda --recheck
update-grub
That actually went very well. Now I will reboot and see...
I got to the grub screen and garuda was there but hung and couldn't load all the way.
I took a pic of the log.
Maybe I need to update initramfs?
The chroot tool still says no linux partition detected
I don’t know, quite frankly there is something very strange in your system. This was unusual (for sure not our standard):
I’d first of all try to chroot again and launch a garuda-update. This will update your kernel and regenerate the initramfs image.
This should have been scrollable, the most helpful part would probably be at or near the bottom, if you get a similar message later 
I tried booting in emergency mode, and it failed at the stage of manually searching by uuid for dev/ disks
But the funny thing is that garuda-update did not fix it, and neither did rebuilding initramfs. Maybe it is trying to mount an additional partition that no longer exists on my disk?
Why did you need to reinstall GRUB?
Or rather, when did the problem start? What had you done?
Maybe you could try restoring the latest working snapshot.
I did something unrecommended...
I restored a system image of my Garuda partition, but I did not restore the EFI partition that belonged to that system image (because it would mess up my Windows boot).
So it is quite understandable that I needed to fix grub.
The story unfolds 
What was your restoration method?
Please post lsblk -f and /etc/fstab.
I restored a Macrium Reflect system image. It is Windows-based software. Can't post terminal output right now, because I am not booted into the live usb.
Windows cares nothing about Linux partitions, other than it wants to reformat them.
So the end of the story is that I was not able to fix my system.
Then I did a Macrium Reflect system image restore the recommended way, which is that I restored the EFI boot partition along with the root partition. Now everything works right.
