Before I risk the process I wanted to make sure this would work. I have an Acer Aspire 7741G-6426 that, over the years, has become painfully slow. I'd like to start over from fresh however I've misplaced the discs I made when I purchased it. Last year I built a new desktop so I have a retail copy of Windows 7. Can I just format using this? Or will Acer's hardware prevent it from working?
