You can use gparted from the boot-repair CD. Shrink a partition by 100MB to free space at the end, then create a new fat32-formatted partition. After that, pick the new partition and adjust its properties to boot/esp. It doesn’t have to be at the start, but within the first 100GB—though you’ll likely want it near the end since moving everything would be cumbersome. Don’t forget to back up any important files before proceeding, as mistakes can be hard to recover from.
You're considering reverting the disk to its original MBR setup to resolve the issue. This could help if the current partitioning is causing problems.
I've successfully set up the 100 MB partition, it took roughly an hour and thirty minutes to transfer and initialize a fresh disk at the beginning. Right now, I'm using boot-repair-disk and attempting to uninstall grub via chroot, but I'm stuck. The error message says: "Command: sudo chroot ... grub*-common shim-signed". After running the command, it shows that the package 'shim-signed' isn't installed, which is causing the issue.
@Kilrah @Sauron Got any suggestions? I've been stuck on this for a while!
