I would like to try to install an OS that isn't XP on an old gaming PC I have, but don't have any Win7 licences.
The system will not however boot anything Win8 or later (i.e. WinPE 4 based). I've looked into the requirements, and it has the NX-bit which was the only thing that I thought might be stopping it. It's a while since I tried, but I believe it would get to the Windows logo and not show the spinning dots.
I've tried a few versions of Win8 & 10, some were betas, x86 or 64, via USB or DVD. (I can try all my copies and report what they all do)
Asus A8R32-MVP Deluxe
AMD Athlon 64 X2 Dual Core 4200+ 2.2 GHz
4x1 GB DDR RAM
2x CrossFire Sapphire Radeon HD 3870 512 MB
Seagate Barracuda 7200.12 500 GB 3.5" SATA HDD
(has used other HDDs in the past)
Ultra X-Finity DR 600W PSU
Has run XP Home Edition SP3 and Linux Mint 17.2 in the past without major issue.
One item worth noting may be the Phanteks AM2 cooler with a pair of hackjob adapter plates for the 939 2-screw design.
