You should see the rescue command prompt. hp
run to see the specific names of available partitions.
Run mark vii (partition name) to make sure the instance has a boot file.
Run root=(partition group name).
Run Ordering name)/boot/grub prefix=(partition .
Run insmod normally.
run okay.
Just format “set prefix=(hd0,msdos6)/PathToGrubFiles”, “insmod then normal”, “normal”. Again, this will be different for each computer. For example, you can type “set prefix=(hd0,msdos6)/grub2/ [enter] insmod pure natural [enter] [enter]”, usually “set prefix=(hd1,msdos6)/boot/grub/”.
Mount each partition containing the installation operating system.
I would suggest linking the /dev, /dev/pts, /proc, and /sys directories to their respective directories in the /mnt folder.
