I have just installed ubuntu 12.04.1. To be honest I had to run installation several times until it was finished fine. When I finally managed to install it properly, I power on the laptop and the grub shoed up! I selected ubuntu generic
. It takes some time to load and when it does I get an error message stating that
error: couldn't read file
Press any key to continue
If I press any button nothing happens. If a leave it there, in a short while there is a black screen loading which gives some weird messages

The thing is that the laptop isn't mine. A friend tried to dual boot ubuntu alongside windows 7 but he didn't succeed. Ubuntu option was in grub, but when you tried to boot it rebooted from the start. So from a Live CD I erased ubuntu, started windows to check if something went wrong, and fortunately everything was OK. Windows started normally!
So I tried to install ubuntu. Before installation was completed the installer crashed! I was afraid that he would lost windows, something that was true...
At that point I tried to install windows but whichever distro(XP, 7{home, proffessional, ultimate},8) I tried it could never reach the end.
So I tried to reinstall ubuntu but I was facing those weird messages. What can I do to move on?

EDIT1: I tried to check and fix(if possible) with GParted it took a lot of hours,although gparted displays only 01:14, I restarted the system and now I get not exactly the same messages.
Numbers in braces [ ]
are different

EDIT2: I forgot to mention that my friend gave a punch to his laptop during a game. After that his cooler became to make a weird noise so I checked and it is a bit tortuous but it is working. What I beleive must be wrong is that his HDD makes a weird noise while trying to load ubuntu, which means he might need a new HDD. Could that be true?
