    did this problem just start ocurring? did you do a fresh install? did you change any default settings? did your friend mention any odd behaviour in the used computer when he gave it to you? did a different OS work on it without issues?

    can you figure out from the error messages what device is not available? can you post the entire error message?


    there could be WAY too many things that are wrong to deduce what it is without more information.
    New to the internet, technical forums, or the hacker / open source community??

    are you getting this after you pick ubuntu from the grub menu? sounds like grub has the wrong drive info and it can't find where ubuntu is. if you can get to grub then on the menu line with ubuntu hit 'e' and see what it has assigned for your drive. you could also boot up the livecd and reinstall grub to your drive and see if it will pick it up.

    Boot up from Ubuntu LiveCD. Open Terminal and execute this
    Code:
    sudo fdisk -l
    Post output here.
    * Its small L in fdisk -l.
    It is amazing what you can accomplish if you do not care who gets the credit.

    This problem did just start occurring because I have never installed Ubuntu till now. And yes I did do a fresh install with Ubuntu 10.04 live cd. I did not change any settings. And there were no problems prior.

    The error you reported in your original post would seem to indicate Grub is looking for a UUID which no longer exists. In addition to posting the output of fdisk -l as suggested, post the output of blkid command. You could copy the 'bunch of numbers and letter' and see if you have that in the output of your blkid.

    Do you know what operating system was on this computer previously?
