Trying to get W7 working on EPYC, Using my known good ISO for threadripper, both the installer and the OS Image BSOD on the following:

0x0000007E (0xFFFFFFFFC0000096, 0xFFFFF8000D64A245, 0xFFFFF880009CB6A8, 0xFFFFF880009CAF00)

Chips are first gen, board is H11DSI (nt). When running safe mode, the last entry before the BSOD is classpnp.sys

Any thoughts on what could be wrong would be greatly appreciated

Cheers.

7E is what happens when Windows can't detect the partition that Windows is installed on

Try swapping the EPYC board to AHCI

Any news?
