filesystem

I'm trying to install ubuntu on my hdd which doesnt contain any operatin system, mbr or grub. (it has 3 partitions, 1st includes my data on ntfs file system, second is linux swap now, and third ex4 filesystem) Of course i don't want to lose my data on ntfs partition. Anyway i installed ubuntu on ex4 filesystem, selected sda as device for bootloader (not sda1,2 or 2). But i got error

Error:unknown filesystem Grub rescue >

I tried ls command. It gives (hd0) , (hd,msdos1), (hd0,msdos2) and (hd0,msdos3).

then tried ls (hd0)/, ls (hd0,1)/, ls (hd0,msdos2)/, ls (hd0,msdos3)/ to find the linux filesystem to boot. But i was unsuccessful. it all gave me unknown filesystem error. Am i missing or something?

12.04 upgrade broke grub? (not wubi related)

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer). However, after restarting, grub can't do anything. Picking the new linux installation… >>> More
