That is a travesty of what it does say.

You have already been given guidance on how to find the Debian partition
from the GRUB prompt.

No you don't.
1. Switch to a console with ALT F2.
2. On my machine I would do
ls -l /dev/sd*
to get the recognised partitions.
3. Then I would mount each of them in turn
mount /dev/sda5 /mnt
and do
cat /mnt/etc/issue
umount /mnt

Did you try the <Go Back> button? Or type "poweroff" or "reboot".
