GT70 0ND Windows 8 Downgrade
« on: 24-May-13, 08:30:08 »

Hello, I'm looking at how to downgrade my OS from windows 8 (pre-packaged from PCCASEGEAR) to windows 7, I have re-initialized my 2x 64gb SSD's RAID 0 setup when I go to install windows it complains that the BIOS doesn't allow booting from the drive.

Any help would be appreciated.

UPDATE:
I am able to install Windows 7 on one of the SSD's when I disable the RAID 0, is there an inherent issue with installing Windows 7 on RAID?

Did you set the bios to legacy mode?

There is an option to allow Legacy boot devices but if that is not it then I can't see an option to change it to.

UPDATE: That worked, thanks. Didn't realize that it viewed it as a legacy device
