I have been searching an unable to find anything that works. I have a Toshiba Satellite A355 with Windows Vista Home Premium SP2 (I think it is the 64bit version) The Windows product code on the bottom of the laptop was rubbed off but I was able to extract the code from the computer. I do not have an install CD and I do not think that one was even included in the initial purchase of the laptop. I found something about restarting it and booting from a partition (F8?) but one does not appear to exist. I also do not have access to the Control Panel; when I click on it, it says "application not found." That is part of the reason that I just want a fresh install to factory settings. Maybe there is a way to download and burn a install disk from the Microsoft website where I can use the code that I have? If I have to order a disk, it would be helpful to find out where I could get one. Any other suggestions? Thank you for your help.
