I recommend using something either than ubuntu.
or Installing to a seperate hard drive or large flash drive like DarkMuse said.
cuz, ubuntu sux.

Your grammar sucks :/

Ubuntu has mounting issues. For example, / will fail to mount, DVD's won't mount and autoplay like normal, /tmp fails to save anything etc. etc. But have you tried updating GRUB to the latest version? Also have you tried looking in Gparted and optionally mounting the whole system manually via init 3 (Ctrl+F2)?
