I'm not the expert but I am going to do my best to help you-
Apparently in Grub Rescue Mode it is locked so we need to find a way to unlock it-
This was the case for this member at Ubuntu-
I just need to know how I can get past the Grub Rescue mode and boot back into my file system.
Acknowledged; that's going to be my focus over the course of the day or next few days to help.
There has to be a way to get around it-
When I was stuck in Grub Rescue in the past I put the Live Debian CD back in my tower and re-installed Debian.
That may seems absurd but it was all I had to go on 6 months ago-
<Solved>grub rescue (think) this might do it-
Hope this helps-
