Hi guys, I just put in a new second harddrive, but my machine won't start into windows anymore (win7 64-bit sp1). I just have a black screen after boot with a blinking cursor top left corner and the HD led on the pc is on permanently... So I decided to pop in the installation dvd and was able to get into recovery environment. Launched the command window and diskpart, but DP lists no drives or volumes... When I take the new disk out, the system boots up normally... I can see where this is going, so is there anyway to use the recovery environment to scan the drive for errors? Chkdsk doesn't work cos no drives are present, supposedly. Can I manually mount a drive? Unfortunately I don't have an external hdd dock to stick the drive in. A little help please, mr. wizard ;-) Thanks!
