Grub : lost my /boot/efi partition

Issues & Assistance
1

Hey all,

After a bios update, i lost my grub…

I tried to reinstall it using chroot with those commands :

mkdir -p /mnt/broken
mount /dev/nvme0n1p6 /mnt/broken
sudo garuda-chroot /mnt/broken/@
mount /dev/nvme0n1p5 /boot/efi
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=garuda --recheck
update-grub
exit
reboot

But i need to recreate, format in Fat32 and use the good label or flag for my /boot/efi partition wich is /dev/nvme0n1p5 .

Can you tell my what could be the right command to do that and where to place it in the chroot ?

Hope to read you soon and best regards.

Please post garuda-inxi (live ISO maybe) and

lsblk -f

chroot from RANI?

garuda-chroot -a

from live ISO

grub-install
update-grub
exit

Hello,

No it’s Dragonized…
I can’t access to the laptop at the moment…
I accidentally delete the /dev/nvme0n1p5 partition so i need to recreate it.

Hey @FenDanT, since you deleted the /dev/nvme0n1p5 EFI partition, you’ll need to recreate it using gparted or gdisk and format it as FAT32 with mkfs.fat -F32 /dev/nvme0n1p5. After that, mount your root partition (e.g., /dev/nvme0n1p6) to /mnt and the new EFI partition to /mnt/boot/efi. Then chroot with garuda-chroot /mnt from the live ISO. Inside the chroot, run grub-install and update-grub to reinstall the bootloader. Reboot after exiting the chroot, and it should hopefully boot into Garuda again.

Hey magnus,

You will have to edit the /etc/fstab. You have to update the UUID to that of the newly fat32 formatted partition, which is mounted at /boot/efi

Thanks Austin,

That did the trick, editing the /etc/fstab and changing the uuid to the good one…

And i have my Garuda byck again :grinning_face:

And thanks all for your help :clap:

And think on it → bios + M$ fastboot disabled. Every time → no warmboot from windows to linux, reverse yes.
Also don’t use the windows partition “permanent”. This is a ntfs partition and it’s not a good idea to work with ntfs inside linux.
If, open fstab and insert the option ro there:

─nvme0n1p3
│     ntfs         Windows-SSD                 52889F11889EF329

as example:
#nvme0 Win 11
UUID=DCEC30FDEC30D40C /mnt/win11pro ntfs-3g noatime,nodiratime,noexec,nofail,ro 0 0
