I recently received a new custom computer from NCIX, and ordered it without an OS with the intention of running only Ubuntu. I've installed Ubuntu from a USB flash drive and the installation appears to succeed and does not produce any errors. On restarting, however, the system appears to be unable to find the bootloader and just hangs with a black screen and blinking cursor.
Booting live from the USB drive I used for installation has let me try to diagnose/fix the problem, but I'm stuck.
Here's the output of boot_info_script.sh (http://sourceforge.net/projects/bootinfoscript/) when I install Ubuntu from the USB drive (live), and run the script before restarting the computer:
Boot Info Script 0.60 from 17 May 2011

The integrity check of the ADV area failed. According

From what I can make of this, it can't find core.img, which explains why it won't boot. I have tried using grub-install to fix it, but it doesn't help.
Specifically, the hard drive onto which I'm installing Ubuntu is a 64GB SSD, if that makes any difference. Does anyone have any idea what might be going wrong here?
Booting live from the USB drive I used for installation has let me try to diagnose/fix the problem, but I'm stuck.
Here's the output of boot_info_script.sh (http://sourceforge.net/projects/bootinfoscript/) when I install Ubuntu from the USB drive (live), and run the script before restarting the computer:

From what I can make of this, it can't find core.img, which explains why it won't boot. I have tried using grub-install to fix it, but it doesn't help.
Specifically, the hard drive onto which I'm installing Ubuntu is a 64GB SSD, if that makes any difference. Does anyone have any idea what might be going wrong here?
