Hi
I lost my boot sector so I need to reinstall grub.
I got my install booting by installing another instance of Manjaro on another disk which found the old install so I can boot directly into to old Manjaro.
I tried sudo grub-install /dev/sdc
this gave this error:
Now my system is x86_64-efi so I tried
which gave this error:
What am I missing?
can you boot on USB iso manjaro
inxi -Fza
sudo parted -l
sudo lsblk -fs
sudo efibootmgr -v
test -d /sys/firmware/efi && echo efi || echo bios
sudo manjaro-chroot -a ( type 1 if only one line 0 )
cat /etc/fstab
exit ( quit chroot )

What do you mean: boot on USB iso manjaro?
I can boot my Manjaro install fine, just not from its own grub install.

You should install grub on /dev/nvme0n1p2
# grub-install --target=x86_64-efi --efi-directory=/boot/efi
You have so many different partitions and disks. Can you describe what is your goal?

I used to have Win10 on nvme and Manjaro on sdc2.
The boot loader on nvme was wiped during a power out.
So I’m trying to reinstall it.
when booted on sdc2, grub-install /dev/nvme0n1p2 --target=x86_64-efi --efi-directory=/boot/efi

Is your NVMe EFI partition mounted inside /boot/efi?
# findmnt
you cant restore grub
recheck all option in Bios to get only EFI
disable secureboot
disable fastboot
no CSM or Legacy
choose UEFI only or first or others ( not windows )
disks on AHCI
no optane RST
and boot in UEFI only on USB iso
inxi -Mza
sudo efibootmgr -v
test -d /sys/firmware/efi && echo efi || echo bioswhat is exactly md125 & md127 ?
/boot/efi is on sdc1 ( also nvme0n1p2 windows )

I think I fixed it.
When booting from USB the stick was listed both as EFI and normal/legacy.
So I booted as EFI and chrooted to my old install and now grub-install ran without errors.
Now I can boot the old install from its own grub-menu.
see with windows boot repair

If you wiped EFI partition, easiest way to fix dual boot is

The nvme with Win10 installed doesn’t show up at all in the BIOS boot menu.
