I just got a new (used) laptop. Most times I dont buy used, but too good of a deal to pass. Hp DV7-4263cl. 2 gig triple core, 650 gig sata, 8 gig ddr3, 17.3 HD screen, etc. I'm only in it for $200, so I couldn't pass on it. It has windows 7 home on it and I wanted to wipe it, and go to windows 7 professional. Put my LEGIT OEM professional disk in it, hit custom, and the hard drive page came up. Before, it showed a 20 gig partition for recovery, and the rest was for the C drive. I was doing something else, hit next and windows 7 professional installed. But -- now I have a 78 gig partition, a 2 gig HP tools partition, AND NOTHING ELSE !! What happened to the rest of the space, and how do I get it back ?? PLEASE HELP SOMEBODY !!! If I run DBAN on the hard drive, will that fix the problem ?? Need help BADLY !!!
