I'm having a problem and could really use some help: I upgraded from 8.04 to 10.04 yesterday; now my system refuses to boot - it hangs at the Ubuntu logo with the five circles alternating red/white, but no hard drive activity. At that point, the mouse works but ctrl+alt+del does nothing. Nor does ctrl+alt+backspace or ctrl+alt+F1. The computer needs to be turned off and on again to restart.
I've booted with the CD and tried mounting my partitions, however I am unable to mount them. Very strangely, some programs (gparted; fdisk -l) see my partitions just fine, however they do not appear correctly in /dev, and in the file browser they're wrong too (I assume the file browser takes its information from /dev?)
My partitions are as follows:
ubuntu@ubuntu:~$ sudo fdisk -l

/dev/sdc2 38659 38913 2048287+ 82 Linux swap / Solarissdb1 and sdc1 were a RAID 0 array on /md0.
sda3 was /home (ext3).
sda1 was /var/lib (xfs).

I gather the info below isn't particularly useful, given I've booted from the CD, but thought I'd include anyway:
ubuntu@ubuntu:~$ cat /etc/fstab

none 2.1G 0 2.1G 0% /lib/init/rwGparted shows the partitions properly, except it shows the partitions as empty.
I don't think I can fix whatever is causing the failure to boot without mounting sda4 to examine the boot info, and I cannot mount sda4 because it is not being recognized. Interestingly, my external 500GB backup drive, attached via USB, isn't recognized either.
Can anyone help? I really desperately need to get this sorted out. Prior to attempting the upgrade, 8.04 ran rock solidly for the past 2.5 years, and the computer runs 24/7.
If I attempt to install 10.04 via the live CD, will it destroy the existing partitions? Or will it recognize them and allow me to incorporate them into the build?
UPDATE:
I used TestDisk to examine the drive and it finds the partitions fine. I'm also able to access the files in some of the partitions (unfortunately not the XFS partition nor the RAID 0 array). I managed to copy various logs via TestDisk (kernel.log, boot.log, everything in /var/crash, etc.) and am happy to share these if it helps.
I tried writing the partition structure to disk using TestDisk, and I also wrote TestDisk MBR code to first sector (which in hindsight appears to be a particularly stupid decision: now when I try to boot it shows a blank screen, except for "1234F:" From the TestDisk instructions, this allows one to select the partition to boot, with "F" being "floppy". Selecting any of these does nothing, except for making the HD light blink very briefly once).
I really, really need help...
Thank you!
