I've been working on dual booting Windows 7 and Scientific Linux 6.4 on my computer (HP Pavilion dv6 with i686 processor and nvidia GEFORCE GT graphics card), and I've run into some trouble with the actual dual boot part.
I couldn't install SL6.4 originally because I got a warning that said "Disks sda, sdb contain BIOD RAID metadata, but are not part of any recognized BIOS RAID sets. Ignoring disks sda, sdb."
I followed the instructions from asymptoticFault on this page http://ubuntuforums.org/showthread.php?t=2038121
After I deleted the metadata, I was then able to put SL6.4 on the parition. I ran into the same problem as asymptoticFault with GRUB, but, I think since I was only using a live version of Ubuntu, I was unable to use "update-grub" because "error-failed to get canonical path of /cow".
I tried to follow the instructions from http://howtoubuntu.org/how-to-repair...d#.UbhsJ9I3tCg
but, perhaps since I an using SL6.4 instead of Ubuntu, when I try to bind the directories (the really long command), the terminal returns " ".
So, can anyone help me update GRUB from the properly installed SL6.4? Or, alternatively, help me update GRUB from live Ubuntu?
