You'll have to download another version in 64 bit, run the eicfg removal tool on the ISO file to unlock all versions, then burn to DVD or write to flash stick using the tool given. Then choose your licensed version to run a Repair Install.

You would need to borrow a Home Basic dvd in order to perform a repair install for that edition if that would work since you have an OEM preinstall on. You can not use the iso for a different edition without purchase of a new product key/license which would then require a clean install to replace the present OEM preinstall.

If you are able to perform an upgrade to repair install with another HB disk the repair will preserve all programs and personal data but typically require device drivers to go on fresh again as well as the need to reactivated Windows by entering the product key on the sticker attached on the machine.

To get around the "invalid product key" error message that may come up you click the change product key option and enter the product key from the borrowed disk which will then see the same. Then you go back and re-enter the OEM sticker key where that will suddenly be verified and see the fresh copy activated since you would have genuine media in use.

Sometines the OEM simply won't take the first time around when you are not using a factory recovery disk. For that you can either use the disk creation utility that comes prepackaged or download it from the manufacturer's support site in order to burn a recovery dvd or two if not written to a usb flash drive. The vendor/dealer can also order a disk for shipping based on your customer information including the serial number for that model.
