URGENT major upgrade bugs

[Elishac]

hello,
i'm starting with linux.
i'm using ubuntu.
the computer offered me to install the last version (9.10, is it), which i did.
then i rebooted.
after this, the touchpad didn't work anymore.
i rebooted, and now, i can't even log in (it says the password is incorrect).

i need a FAST answer please, because i'm using a neighboor's computer, as mine is blocked at the login page (i don't even know how to make it stop without unpluging the plug).

i hope this forum will be able to help me, it's the second one i'm trying.

What's weird is that, when i start the computer, it says "boot on ubuntu 9.04".
Do you think this has anything to do with my problem?
if yes, how to solve it?

[Elishac]

can this have anything to do with the bios or something like that?
(like: the bios still thinks it's 9.04, and tries to load some files that don't exist anymore?)

help me please?

[Elishac]

I guess a fresh installation is the only remedy. Boot from the live cd of Ubuntu 9.10. Back up ur data. And then go for a fresh installation.
Upgradation to 9.10 is giving grub2 nightmares to many.
You can download the live cd from ubuntu.com
