I'm trying to install 12.04LTS on a server but keep running into the unable to install grub error like so "Unable to Install GRUB in /dev/sda". The drives are in raid1 and I'm using fakeraid on a supermicro motherboard, which according to the manual is fully supported. I've tried installing both from USB and CD-R but still no luck. I'm not dual booting with any other OS, just using 2x320gb drives and have been choosing to install using the entire disk.
Any ideas what I'm doing wrong or can do to fix this? Thanks

As I seem you should have used guided partition skim, when you are going to install grub it doesn't see that, so you should make a small (1MB) partition on each disk and RAID them together and set it as a GRUB boot partition. Set up your other RAID partitions (e.g. swap and /) and then the GRUB installer should find the boot area just fine.
