I was trying to restore my Gateway computer back to original factory settings by using the internal reboot f8 option, but I accidentally shut the computer down while it was reformatting and then I just couldn't get back to that option of rebooting the computer. Therefore, I decided to use the operating system disc that Gateway gave to me when I first purchased this product, and it worked. But, the only problem is I just can't seem to get the 64 bit version of windows vista despite the fact that I clicked that I want the 64 bit version. I tried reinstalling the operating system 3 times clicking the 64 bit version all 3 times and yet I still get a 32 bit windows vista. How can I fix this? And, can I still somehow restore the computer back to original factory settings even though I reinstalled the operating system?
