Your exits are very few. Maybe you can install any of the nice Linux and sell it off that way.
Okay, so to start off I'll just say that I seriously screwed up, since I wanted to sell the laptop I was going to format the hard drive, while keeping Windows. I had dual booted Linux Debian onto it and since I didn't know how to use the recovery disk I formatted the drive and reinstalled stock win7 64 bit. So my options now are to install every single driver for the laptop from Lenovo (which would be great if you could link me to them) or restoring it to an OEM version of win7, only I have to buy a recovery disk, which is like NZD$150 (USD$100) and since this is a pretty old laptop I don't want to spend money on it.
Any answers are grately appreciated.
