Grub rescue, symbol 'grub_disc_native_sectors' not found

Hello.
I ran into a little problem after doing some updates and getting some errors. I tried the GRUB/Restore the GRUB Bootloader from wiki and it didn’t work.

Terminal log for every command in grub restore guide in order from the wiki

What should I do, and if it can’t be fixed, is it possible to retrieve files from the system booting from usb?

You have a msdos parted disk and used

which is the syntax for gpt parted disks.

For systems booted in BIOS mode (I can’t see if you did) with an msdos parted disk, the grub boot loader must be installed in the MBR of the disk, check the wiki again. Don’t choose any partition.

This command might be helpful:

test -d /sys/firmware/efi && echo efi || echo bios

It shows with high probability how you booted. It should be done from running system or when booted a LIVE ISO after chrooting.

I’m pretty new to manjaro and linux in general and don’t really know these things. I ran the command and it returned efi

Please post result of command

mount
sudo fdisk -l
sudo efibootmgr -v

Also, it worth to investigate what capabilities your firmware provide. As user you should better know if you boot in UEFI or BIOS mode when doing an install and please remeber for the furture the recommended correlation:

UEFI + gpt

or

BIOS + msdos (MBR)

Mixing these thinks could cause issues (at least for newbies).

Looks like you booted in UEFI mode using the ESP of the USB stick or using /dev/sda1 which is not formatted in FAT32! Is this wanted? (Some people do, that’s the reason I’m asking.)

I would not leave it this way. First you need to decide if you want to boot in UEFI mode or in BIOS mode (as long as your firmware supports both). If you want to proceed in UEFI mode: Backup and freshly setup your system. I would not say it’s impossible to transfer your system disk into gpt but it’s probably easier to re-install.

Or stay in BIOS mode and use the correct way to install grub, see wiki. Afterwards, make sure to boot in BIOS mode.

I think the easiest thing for me to do is to backup everything important, reinstall manjaro and just take this as a lesson on not mixing up the modes. Thanks for the help. :+1:
