I recently upgraded from xp to 7. I used to be dual booting xp and 7 beta. When I upgraded, I decided to remove the partition that 7 beta was on and expanded the xp (now upgraded to 7) partition to the full hard disk capacity. However, after deleting the second partition the new Windows 7 is still not accessing the full hard disk. Furthermore, I still get the dual boot option even though there shouldn't be any other operating system to boot.
I used GParted to first delete the unwanted partition and then expand the desired partition to the full disk capacity.
To summarize, the following is a chronological list of what I did and the problems I am now experiencing.
Dual booted with xp and 7 beta (60 GB to xp and 30 GB to 7 beta)
Upgraded xp to 7
Deleted Windows 7 beta partition
Expanded Windows 7 partition (60 -> 90 GB)
1) In "My Computer", drive c is still showing a max of 60 GB, but disk management software in Windows 7 and GParted both show 90 GB.
2) I still get the dual boot screen when my computer turns on even though I now only have one operating system.
