I have a Toshiba Satellite P755-S5390 running Windows 7 Premium and it has been slow and sluggish lately. I am in the process of building a new desktop that will be using Windows 10 so I figured I would reset my computer to factory to wipe out what ever was slowing it down and then take the free windows 10 upgrade so that I could start getting used to Windows 10 awhile. On the Toshiba there is an internal backup so I restarted the computer and held in 0 to pull up the option to reset to factory. Going through it all it gave the option to clear the hard drive (I assumed this ment clear the hard drive before reinstalling) but afterwards it seems as if maybe this ment to clear the hard drive, including the partition that had the backup because I now have what seems to be a totally blank computer. I assumed I could go to Toshibas website and download what I needed to reinstall, but they want to sell you a CD, and I really dont want to spend money on a CD and wait days for it to come when I should be able to fix this myself. The drivers are all on the website to download, but windows 7 premium is not. Apparently it used to be online for download from the microsoft site, but is not anymore? My windows key is on the bottom of the laptop still so I do have that. What suggestions does anyone have? Thanks in advance for your help!
