Hello everyone, I'm a long time windows user and it-tech but I have long felt that my geek-levels were too low so I installed Ubuntu last week (9.10 x64). Hopefully I can make it my primary OS.
I have two 80GB drives in RAID-1 from my nforce raid controller, nforce 570 chipset.
Then a 320 GB drive where I placed ubuntu and it's also where grub placed itself.
And also a 1TB drive.
When grub tries to boot XP I get the error message: "error: invalid signature"
I checked the forum as much as I could and tried a few things, but no change.
Drives sdc and sdd are the two drives in raid, they are matched exactly, but detected as different here. I really think they should be seen as one drive.
So any suggestions on how I can make grub work as it should?
Also, if/when I need to make changes to grub, do I really have to use the live CD?
