RE: Windows 8 Dell inspiron 7520 installation problem
Your first problem is the fact that the original key is embedded on the motherboard. You should have requested the installation disks from Dell, not purchase new ones. Your second problem is that the disk you purchased is an upgrade disk. You cannot use it. All retail disks and downloads for windows 8 are upgrades and require win 7 or earlier on the hard drive. Return the misrepresented win 8 pro to the store. Request the installation media from Dell here--there might be a small fee:
The only full version of win 8 is the OEM System Builder version available only online from a few vendors like Amazon.You don't want that version either since it is not supported by Microsoft and Dell.
