Could you please create rescue image, boot it on a problem system and
show output of

ls -l
hexdump -n 512 (hdX)

where hdX is your normal boot disk. To create rescue image

grub(2)-mkrescue -o /tmp/rescue.iso

and you can then dd this ISO to USB stick, it should be bootable both
as CD-ROM and HDD.
