Windows 7 / Ubuntu Dualboot GRUB Problem.
- by Tek
I'd like to first say ahead of time that I'm running a RAID-0 Setup.
1.First of all, I'm glad Ubuntu 9.10 installed flawlessly and detected my RAID-0 setup just fine. The issue I'm having now is that I already had Windows 7 installed and made a small 12GB partition for Linux/Swap.
I grabbed EasyBCD 2.0 to edit the W7 bootloader and configured it to use dual boot Grub2 because before it didn't even show the option for Ubuntu.
The bootloader points to a file made in the windows directory made by EasyBCD called "C:\NST\AutoNeoGrub0.mbr" which is what I'm guessing grub is booting from.
After that I got the option for booting Ubuntu. The problem is that it's sending me to the Grub prompt (probably because it's pointing to \NST|AutoNeoGrub0.mbr?), at first I didn't know what to do but I researched and have to type grub commands to manually boot into Ubuntu Linux.
Ex:
grubroot (hd0,4)
grubkernel /boot/vmlinuz-2.6... root=/dev/disk/by-uuid/24624-2424...
grubinitrd boot/initrd.img-2.6...
grubboot
After all that Ubuntu boots just fine, but how do I fix it permanently? Do I need to edit the bootloader manually (since Easy BCD "autoconfigures")? Some insight on this would rock!
Also, it sucks to type the actual uuid since it's REALLY long. I tried getting the name of the drive via fdisk -l but since it's raid 0 I'm guessing I can't do that. How can I get a shorter name of the drive? like /dev/sda, /dev/sdb etc?
I've also tried to update to the latest GRUB and I got this:
Creating config file /etc/default/grub with new version

grub-probe: error: no mapping exists for nvidia_dbedfcca5'

dpkg: dependency problems prevent configuration of grub2:

dpkg: error processing grub2 (--configure):

No apport report written because the error message indicates its a followup error from a previous failure.
E: Sub-process /usr/bin/dpkg returned an error code (1)
I've also tried:
b@dnb:~$ sudo update-grub

To no avail. Any idea what I can do to fix this mess? :(
Edit: This is my disk configuration.
b@dnb:~$ sudo df -l
