Hi Nuno,
I followed the instructions from this page:

rebooted without the livecd, and nothing. I put my hand on the top of the system, and it feels like the hard drive keeps searching for something to load. I am wondering if my harddrive is failing.
Any tips on how to test/fix it are appreciated.
If I understand the state of your machine:
1. you did a reinstall from DVD, and all went smoothly until you
rebooted, at which point the machine just hangs (by any chance, does the
message "boot from CD" show up at that point?)
2. if you boot from a LiveCD, the machine comes up
3. you tried to do a grub-install, but it didn't work
Assuming that your hard disk is /dev/hda (otherwise replace hda with
your disk's name), try this:
i. boot from a LiveCD
ii. mount your hard drive - say, with:
mkdir test
mount /dev/hda test
then start looking around in test, to see if the disk looks ok (do some
ls commands and such)
see if ls test/boot contains grub and such
if it looks like that's all good, then:
iii. unmount the hard disk with:
umount /dev/hda
iv. then try this to rebuilt grub and the mbr:
grub
root (hd0,0)
setup (hd0)
quit
v. if all goes well, you'll have a properly installed grub and mbr
vi. try to reboot from the hard disk
