Hi guys,

Bad thing happened to me today, i rolled back to win 7 from 10 and when it boots, the win 7 splash screen freezes then i get a blue screen error code "0x000007B". Same thing happens in safe mode. And in linux and my recovery tools on the windows cd, my windows drive is D not C. I would rather not reinstall as its an OEM licence meaning id have to buy another key, unless i talk to ms. Any help please, this is my school computer so i am in a rush to get it to boot.

Clean Installation is the only solution that I see here.

Do you have the OEM key on the back of your PC?

EDIT: Your windows 7 key was an OEM key? Not a prebuilt OEM license?

I have a sticker under the battery on my HP Probook 4530s. Im still going to have a go at MS through answer desk since this shouldn't happen when downgrading.

Well, then, you can re-activate without calling. And if you deleted the Windows.old folder, then you'll never be able to roll back. Clean re-install is your only option.

Can you try and do a startup repair using an Windows 7 USB Boot drive or DVD?

I have tried that and it said scan for viruses and remove all external devices. It also said it could not determined the cause. The error code on the BSOD is associated with having the sata controller set to ide instead of ahci on win vista and up. Mine is set to ahci though.

If you try to set the SATA controller to IDE mode, can you boot up into Windows? If you can, we can fix it.

There isn't much we can do at this point. Do you have important data you need to backup? You can always use a linux distribution like GParted: http://gparted.org/livecd.php

to backup anything important before reinstalling Windows.

Now ive copyed my files off, dare i try using the win 10 iso to upgrade the broken windows, in the prosses fixing the boot files causing the issue? Or could that jeopardize my license. If it wont ill do that then if it fails, ill use the recovery partition to favtory reset since it doesn't get effected by win 10
