ubuntu fails to boot, grub doesn't work

Here I go baby!

I've got 3 discs. I use two of them (sda, sdb) for storing files and games. On the third I had two partitions: one with windows (sdc1) and one spare. So I decided to install Linux (Ubuntu 8.04 LTS). I’ve made 3 partitions instead of the spare partition: swap (sdc2), root (sdc3), and user (sdc4), and used default GRUB install location (hd0, should go straight to the MBR).

Ubuntu is installed successfully (I guess), yet it doesn’t boot. Windows start as usual (NTLDR works fine) in all its gory… erm glory. No system choice. The only change: I've got only one partition on the disc instead of two, from the windows point of view, and the drive’s free space seems much smaller than it really is (this I consider normal).

I believe, that for some reason GRUB did not install to the MBR or the default install location is wrong for my PC. Reinstallation doesn’t work.

Terminal commands through LiveCD:

sudo grub
find/boot/grub/stage1
root (hdx,x) #x,x meaning whatever it will say in previous step I think it was 2,2 as far as I remember#
setup (hd0)
quit

Or perhaps I did something wrong? None of my friends have had this problem before, and there is no way I can find answer to this anywhere, so please help me out. I really enjoyed Linux, on the other PC, and Ubuntu Live CD as well. I need Windows though, so dual-boot is the only option.

Thanks.
