Here you see the filesystem on the partitions is: nfs
Please reconfigure it as: ext3 (filesystem code for fdisk is; 83)
fdisk /dev/sda > n > p > 1 > enter > +sizeMb/Kb > enter
n > p > 2 > enter > +sizeMb/Kb > enter
n > p > 3 > enter > +sizeMb/Kb > enter
n > p > 4 > enter > +sizeMb/Kb > enter
(for example, after thsi you need to specify the kind of filesystem ext2, ext3, ext4 or something else)
And don forget the SWAP-partition, in case you run out of memory the system will use that, like the page-file from Windows.
Hope this helps,
