From my knowledge, the partition for our os is split into two, an fat32 for booting and ext4 for the system. Due to my curiosity into tweaking stuffs, I had accidentally wipe out the fat32 one (the partition is still there, but most of content gone) , while the other luckily remained.
/dev/n...p5 for fat32 and /dev/n..p6 for ext4
Now while I still can enter the systemd-boot menu at BIOS screen, theres only remaining option for “reboot to firmware”.
Is there anyway to restore or reinstall the boot thing back?
Thank you in advance!
Some useful info
-Spec:
- Desktop: Plasma KDE
- Kernal version: 6.2.2-arch1-1
- Installed using systemd-boot
-The ext4 is still quite fine (i guess?). I can still chroot it using my USB live image.
-Disk info from some commands
[root@EndeavourOS /] → chroot from usb img to ext4
[liveuser@eos-2023.03.06 Desktop] → user from usb img

Couldn't find EFI system partition. It is recommended to mount it to /boot or /efi.
Alternatively, use --esp-path= to specify path to mount point.
