I'm only posting this question because it seems I've been trying to get this to work for the last 2 weeks and feel like im exhausting my options.
I'm trying to build a persistent Linux system (BlackBox) on a USB flash drive. After multiple unsuccessful attempts with casper files and different partition schemas, I continue to get a 'No Bootable Device' message after selecting the flash drive from refind.
In my latest attempt, I ran the boot-repair tool to install Grub in the EFI partition. Here is the result file http://paste.ubuntu.com/8300147/
My partition table looks like this
- sdb1 - EFI partition with Grub installed
- sdb2 - BlackBox Linux
- sdb3 - Data partition /home
- sdb4 - Swap
Can anyone see what might be the problem from the boot-repair logs? If I can provide any more useful information please let me know in the comments.
