I just booted from the amd64 ubuntu install disc, and went through the partitioning and installation. It told me to remove CD and restart to finish installing some more packages. However, when I did this, my motherboard reports "Error loading operating system". I tried everything again, and the same thing happened. I'm using a single SATA hard drive (no RAID), and I suspect this is the problem, but the partitioning tool saw the hard drive (said it was SCSI), and allowed me to write new partitions to it and everything, and it appeared to copy files during the installation. Does Ubuntu just have a problem with my mobo's SATA card perhaps? I am about a step and a half above a Linux newb in that I've installed and used plenty of distros fine, but this is the first time I've tried any distro with SATA.

Jusr a stab:
'my motherboard reports "Error loading operating system" '
might be the BIOS looking for the OS in the wrong place e.g. floppy or CD. Perhaps a suddenly inactive boot partition needing you to check with fdisk or similar?

I'm new to Ubuntu (have Kubuntu actually). But I remember that in the partitioning part you had to put a "Boot flag" to on, so ubuntu knows what is the booting partition. Because profada is right, it's the BIOS looking for the boot loader. I had the same problem when I messed up my MBR (actually I think that I just messed up all of my bootloaders, so the BIOS couldn't load anything)
You can always try to boot Ubuntu Live or Knoppix and check to see wether theres a boot loader (if you're not sure), but otherwise, it might be an MBR problem...

Good luck!
