Explanation / Answer

Its really hard to trace with this simple image. But, with my suggestion, there could be a disk failure, or grub failure. These are the 2 possibilities of many.

If disk failure, try booting the machine, with a UEFI activated, and boot from your pendrive. This should boot the machine, by all means, and you can check there, if the disk exist, and is in working state. For this to happen, you have to prepare a bootable pendrive, with the operating system of your like, either Windows or Linux will do.

The other possibility is GRUB failure. In this case, once you enter into the rescue mode, you can try these instructions:

>set root=(hd0, 6)

>set prefix=(hd0, 6)/boot/grub

>insmod normal

>normal

Hopefully, this should work. If you still unable to boot, better you contact your system admin.
