The issue: Windows 7 wipe hard drive without CD

“Hi, I recently built a new PC and I'm looking to sell my old tower. Therefore I need to reset the PC to factory settings but when I go to 'advanced recovery methods' it says: 'Reinstall Windows (requires Windows installation disc)'. I do not have the disc and have no way of getting it from the original retailer. I have googled it and I found something about booting from a partition with the Windows ISO? I am not sure what to do, so if I could get some help figuring out what to do that would be nice.”
