sudo fdisk in a live session does not show all hard drives
- by cornbread
I am having Grub2 issues in my Ubuntu 10.04 dual boot, 2 hard drive system. So I am attempting to follow the standard grub2 reinstallation guide (cant post link because of spam filters allowing only one... ?_?)
Don't know if this is the root of my problem, but my speedy internal HD with my OS on it is not showing up anywhere in a live session.
Not in nautilus, behind fdisk.... no where. When I can get the main system to boot, there is no issue seeing all available partitions. But the live session sees only the 1TB internal media/backup hard drive.
I need access to the other hard drive and it's partitions to finish the grub2 re-installation but I am not sure anymore that is the underlying issue. Anyone have experience with this?
The issue I have identified as a grub2 issue is fully described here. SandPvvr describes it exactly.
Some notes:
I do not see the grub2 menu for my os's
holding down the shift key after my bios screen works maybe 10% of the time
Not related to reinstalling a windows os. havent been touched in a year
do some web development. issue may have started when I was playing with ruby and django. not sure on this. Could a dev environment do this?
