When booting a Virtual Machine powered by a Debian 8 "Jessie" distribution, this error message appears :
Error 24: Attempt to access block outside partition
1
I'm quite sure that it's a GRUB problem ; GRUB don't find my boot partition which is on /dev/sda1 but i've tried to boot the system with a live CD and then, could you explain how to repair GRUB to fix my problem ?
Thanks in advance and best regards
