Problem starting Ubuntu 9.10

After the screen of the Ubuntu 9.10 logo, the screen goes black and after waiting for a few moments my splash screen doesn't appears, and if a I hit any key an errors comes out telling that the boot device couldn't be found.

The thing is that I perfectly booted Windows Vista, so help please.

grub?

It is your first boot after install? What did you do? Tell me some details. Try boot your installation CD and run ALT + F2 and then run "gnome-terminal". Run the command "sudo update-grub" in the terminal and then reboot.

grub...

Well no it was just another normal boot, sorry I didn't give you more information, I've been running Ubuntu 9.10 since a while now and this is first time. I'll try your option first.

I just hope not to reinstall and erase all my data. Still, I'll copy what it tells me and I'll post it in a moment.

Thanks again.

The error

This is what I read from the problem:

"Gave up waiting for root device. Common problems: 7f665059d1d
- 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/628a7736-bb5d-4dbf-b62e-67f665059d1d does not exist. Dropping to a shell!"

Gave up waiting for root device

I encountered this problem when I first upgrade my jaunty to karmic. I summarize the steps that I used to resolve this in my blog.

Same Problem Here, Different Cause

During a fresh install of Karmic, I started having this issue. I'm still not positive why it's occurring, but I have found that if I wait a minimum of the 10 seconds (usually much more) that it takes the grub 2 boot to timeout, it will boot. I reboot so rarely, I tend to forget about the issue until then. I do believe it may have something to do with one of my USB devices and the timeout on the device, though.

(Vista boots with no problems on the same system. Haven't used it in months, though.)
