To preface, everything I'm doing here is EFI, I'm not touching MBR or legacy boot at all.

I have a USB drive with multiple partitions.
On the first partition, I have Clonezilla Live.
On the second partition, I have GParted Live
On the third partition, I have the Windows 10 installer.

Depending on which partition I select in the UEFI, I go to the respective loader. Clonezilla and GParted load their respective GRUBs, and Windows loads it's installer.

However, if I select any option on the GParted partition, it loads clonezilla.

I figured this was simply a case of GRUB being configured incorrectly, and assumed it had to do with how root was being set.

By default, the menuentry is this;

menuentry "GParted Live (Default settings)"{

  search --set -f /live/vmlinuz

  linux /live/vmlinuz boot=live union=overlay username=user config components quiet noswap  ip= net.ifnames=0  nosplash 

  initrd /live/initrd.img

}

My assumption was that the search parameter was finding vmlinuz on the clonezilla partition first, and setting that to root since that's the default of the --set flag.

I tried three different alternatives to correctly set root to the GParted partition;

menuentry "GParted Live (set root)"{

  set root=(hd0,gpt2)

  linux /live/vmlinuz boot=live union=overlay username=user config components quiet noswap  ip= net.ifnames=0  nosplash 

  initrd /live/initrd.img

}

menuentry "GParted Live (uuid)"{

  search --set=root --fs-uuid 12FA-2F46

  linux /live/vmlinuz root=UUID=12FA-2F46 boot=live union=overlay username=user config components quiet noswap  ip= net.ifnames=0  nosplash 

  initrd /live/initrd.img

}

menuentry "GParted Live (name)"{

  search --set=root --label GPARTED

  linux /live/vmlinuz boot=live union=overlay username=user config components quiet noswap  ip= net.ifnames=0  nosplash 

  initrd /live/initrd.img

}

All three of these options boot Clonezilla, even though it's clearly pointing to the correct partition with GParted on it.

However, if I delete clonezilla from the first partition, these all boot GParted as they should.

I've got no idea why GRUB is looking at the Clonezilla partition during boot.

My original intention was to have a small EFI partition with a GRUB install, and then have different options for the three installers, as well as an EFI firmware edit and memtest. Essentially turn it into a swiss army knife USB drive. However, I don't really want to spend the time setting that all up if for whatever reason I can only boot Clonezilla and not GParted.

Any ideas?
