I have windows 8 64 bit oem dvd that I bought. but what I install before was 8.1 preactivated dvd. this is installed on a ssd drive. now i'm trying to format the drive to install windows 8 to make it legal but it said that the dvd is not bootable. and to put in the media that is on the computer. what can I do
Hmm ... if i get this right the PC wasn't shipped with Win 8, what means there is no MSDM table in BIOS to achieve OEM_DM activation. What key will be used to become genuinely activated? Is that media you got actually an install media or any kind of recovery media? Either way you could still opt for installing a fresh Win 8.1 with update version .
Still there is NO REASON that the OEM DVD should not BOOT, if purchased from a 3d party - NewEgg, TigerDirect etc. So unless he does not have Boot to Sequence set Properly. there is NO REASON the DVD will not BOOT. I can boot the Dell with Acer or Acer with Dell - install NO. but BOOT YES
Is this a laptop you're trying to install Windows onto? If so, perhaps you need to disable Secure Boot in the BIOS.
