My PC comes with an OEM copy of Windows 8 (regular), but I only have a Windows 8 Professional DVD. Will Windows 8 automatically detect the edition associated with the product key in my BIOS and install Windows 8 (regular) instead of allowing me to enter the key for the Professional edition?

(I have an Asus Q200E Win 8 Core OEM laptop. I borrowed a Windows 8 Professional DVD from my friends, so naturally, I can’t use his product key.)

  • It should work but there is no guarantee you really should use the ISO meant for Windows 8 Core.

  • If your pc came with windows 8 then it has a recovery partition unless you deleted it. If you did then contact the brand and request one. Its unlikely your OEM key will be automatically picked up by a Windows 8 Pro media depending on what its actually use ( curious of the source ).

  • No one can answer this question without knowing the make and model of the PC. Most PC's have the ability to make factory recovery discs.

Copy the contents of the DVD onto a folder and then go to /sources and create a file called ei.cfg, and paste the following info in it.



Now make an ISO of the folder and burn it onto a DVD, now during installation, you will get a popup asking you to select the version, select Windows 8 Core and it must work
