I bought our computer from Freegeeks with Ubuntu 8.04 installed. I upgraded from Ubuntu 8.04 to 10.04 on Thursday November 10. I have an ASUS P4P800SE with dual Intel P4@3GHZ.

Installation messages were: - Error loading Nautilus config info - Replaced customied /etc/login.defs - Replaced customized /etc/dhcp3/dhclient.conf - 189 packages removed - WARNING: Failed to read mirror file

When I rebooted, the usual ASUS screen appeared, then "Loading GRUB" then "starting Up..." then "starting Up..." again then a blank screen (the moniter went dormant).

I rebooted, started GRUB and selected: version 10.04.3 LTS kernel 2.6.32-35 generic I got the same results.

I rebooted, started GRUB and selected: kernel 2.6.24-29 generic

Here's what was displayed:

udevd [875]: error getting socket:
 Invalid argument
libudev:udev_monitor_new_from_netlink:
 error getting socket: Invalid argument

Segmentation fault
**Gave up waiting for root device**
 Common problems
- Boot args (cat/proc/cmdline)
- Check root delay
-     check root
- Missing modules (cat/pro/modules;

**Alert!
 /dev/disk/by_vvid/c59c6361 etc...
 does not exist. Dropping to a shell.**

Then Busybox v1.13.3 started with the following prompt (?)

(initramfs) _

But my typing did not appear on the screen.

It appears the hard drive cannot be found. Any suggestion on how to remedy this? Thank you.
