    It's not a very well described tutorial to fix the grub rescue no such device issue. But I hope you've got basic the idea to deal with the error no such device issue.

    First you need to boot linux somehow then reinstall the GRUB bootloader and update the GRUB configuration. Here's the detailed GRUB rescue tutorial.
