The code that I gave was code to be used in the grub.cfg. In that code
that I gave the "search --set=root --fs-uuid UUID_HERE" line tells
grub what partition to load the kernel and initrd from, and the kernel
parameter "root=UUID=UUID_HERE" tells the kernel what partition to use
for mounting the root filesystem.

Please post the output of "sudo parted -l" and "sudo blkid" and I can
probably give you the exact code which should go in your grub.cfg.

The other option is to simply mount the partition on your flash drive
to /boot/ (using /etc/fstab so that it will always be mounted there)
and then you can use grub-mkconfig rather than writing a grub.cfg
