Ubuntu 9.04 Installation Woes

[Rob]

Alrighty folks...here is the latest in my continuing attempts to get
Ubuntu 9.04 installed on my computer.  

I went ahead and sprung for $15 for an Ubuntu magazine in Barnes and
Noble that had the 9.04 disk included.  This morning it appears to have
installed successfully on my external drive (a 500 gig Seagate) and it
also appears that Grub was successfully installed on HD0 since when I
rebooted, Grub appears showing the options of operating systems to boot.

When I choose to boot Ubuntu, the Ubuntu Splash Screen appears and I get
the following:

Boot from (hd2,0) ext 3 eb309597-f711-458-b3b7-0a281dae6281

Starting up...
[  1.964023] ata1: softreset failed (device not ready)
[  2.628016] ata2: softreset failed (device not ready)
[  3.292017] ata3: softreset failed (device not ready)
[  3.988017] ata4: softreset failed (device not ready)

modprobe: FATAL could not
load /lib/modules/2.6.28-11-generic/modules.dep: No such file or
directory

Loading, please wait...
Gave up waiting for root device.  Common problems:

- Boot args (cat /proc/cmdline)
  - check rootdelay= (did the system wait long enough?)
  - check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls/dev
ALERT! /dev/disk/by-uuid/eb309597-f711-458f-b367-0a281dae6281 does not
exist. Dropping to a shell!

BusyBox v1.10.2 (Ubuntu1:1.10.2-2ubuntu7)built-in shell (ash) Enter
"help" for a list of built-in commands.
[initramfs]

When I use the Super Grub CD to boot it sees Ubuntu 9.04 Kernel
2.6.28.11-generic as a boot option but selecting it yields:

Error 15: File not found
press any key to continue

If anyone has a clue as to what could be going on here, I'd be grateful
for any assistance.

Regards,
Rob
