Hi there

I have an old Acer Aspire 5520 laptop runnung windows vista and it has major problems with its operating system even after i use the factory recovery disks. I want to try and install windows 7 via USB on it but the thing is i dont want anything bad to happen to the computer and i am now unable to restore it to system default because the DVD drive is stuffed. Is there anyway i can access the hidden recovery partition on the hard drive?
