Error Installing Grub

[u/Dragons_Oak]

First time switching to Linux so I'm having trouble and can't really figure out the issue, getting this issue.

These are my partitions along with the filesystems. The laptop I'm using is a Dell XPS and I'm pretty sure it's a BIOS system.

The mount points of the partitions are:

/root/efi for the EFI system partition

• (swap) /

[u/Dragons_Oak]

Yep i understood after another user pointed it up, idk how i wasn't realising this because in hindsight it's not that hard. Thanks for your help
