1.it's a eee pc netbook which had ubuntu 12.04,backtrack4 and windows 7 installed on it.
2. i wanted to install windows xp instead of 7, so i used a win xp cd and first deleted win 7 partition and then installed win xp instead.
3.then grub gone!! and when i used ubuntu live cd to restore grub but i faced a problem and unfortunately all boot loaders gone.
4.using gparted within that live cd i saw that my home ext4 partition has gone too!!!( it was so important for me).
5.i used hiren's boot cd(testdisk utility) and fortunately my home partition were there.
now... how i can do all these problems i faced??
