I have two hard disks,one of 40 GB and the other of 200 GB.On the first one I had a 10 GB primary partition and a 30 GB extended one.on the primary partition was installed windows xp.n the extended partition there were two logical drives,one of 20 Gb and the other of 10 GB.I had installed linux on the 10 GB drive,and the 20 GB drive was left for windows applications and stuff.Now accidentally I deleted the 20 GB logical drive and soon after that the disk management utility gave errors.When I rebooted the system,it would'nt boot.So I re-installed windows xp on my 200 GB disk,but from here I cannot see my 40 GB hard disk.I can see it in the BIOS settings though.Pleas help!
