So long story short, needed a cheap, decent used laptop for business reasons (mostly to run Coreldraw and stuff for a laser engraver, don't judge it's not like this is my gaming rig) and I found a decently priced one at the local state gov't surplus auction, so I took a plunge and bought it. This is what it would be if it was new: http://www.newegg.com/Product/Produc...82E16834157279
Looking over it, almost everything checks out. Right processor, amount of memory (even if an oddly low number is available), a bit scruffed and used on the outside, screen is ok, etc. However, the previous owner or whatever state employee yanked out the 640gb hard drive and swapped it with some crappy 55gb one that must have been in a Dell laptop or something as it references Dell crap on a HP laptop, even the admin account username is Dell. So kinda peeved, but it is what it is, and since auction places are jerks and won't let you return despite the improper description, looks like I'm stuck with it.
So in trying to make the best of this scenario, what are some options for me here? The Windows 7 product key on the sticker must be an OEM one as I tried downloading the iso or whatever from Microsoft's website (BIG disclaimer here, I am not a techie and have limited experience with software stuff like this, so I am likely butchering terms) and it was giving me an error to contact the manufacturer, which I can't obviously, and it didn't come with recover disks and the like. So it doesn't look like I'll be able to wipe and restore it, which I wanted just because who knows what might be on the laptop despite it looking clean. Is there any advice out there regarding how to make sure it's clean without the ability to just wipe it all if I choose to use it as is?
The other option I think I have is... I --- think --- I have a Windows 8 download and product key I can use, my main PC runs Windows 7 and this was back during the push to get people to upgrade to Windows 8; I never did, but I decided to go ahead and download whatever files Microsoft was giving away at the time in case I ever decided to (which I didn't). So I have a product key for it and what I think are the installation files, and unless there was some expiration date on that offer they should be good right? However if this is the case, I don't want some lousy 55gb random/used hard drive. Is it possible to go out and buy a laptop hard drive (nothing too fancy, was thinking just a basic 500gb one), then install this Windows 8 product onto it?
If anyone has some helpful advice, that would be great. Thanks!
