Windows 7: Cant format old system drive after dual boot install

14 Nov 2012   #1

Windows 7 Professional 64 bit
Cant format old system drive after dual boot install

Hi all

Please bear with me I'm new at this and a little unsure as to exactly what I'm doing.

A few months ago I was having trouble with an incredibly slow system running Vista 32 bit. I run some RAM hungry programs so decided I'd try a Win 7 64 bit system, and if it was stable I would then look to increase my RAM beyond 3GB (Apparently my motherboard will take 8GB of RAM)

A screen shot of my basic system info is here...

I obviously now want to stay with Win 7 64bit and format the Vista drive for the storage space but have no idea how to make my Win 7 drive the system drive and then format the old Vista drive.

I hope I've given enough info, and my request makes sense.

I'd be really grateful of a fairly straight forward "how to". I'm reasonably savvy and can follow instruction but certainly no expert.

Many thanks in advance
