I have Windows 7 installed (32-bit) and want to upgrade to 64-bit. My PC is 64-bit ready. I have read that to do this I need to do a clean install however when I boot up from the disc drive it says press any key to boot from DVD and when I do it just loads windows normally, it won't load in to do a clean install. I tried the 32-bit disk and it's doing exactly the same thing, it just won't start the clean install, keeps loading windows as normal. It's a bought original disk. I tried making a bootable usb and run it from there but that didn't work either. Any ideas? Oh and I'm definately pressing the press any key bit in the time frame. Can someone help please?
