@denzilferreira @thelinuxEXP @elementary Thanks very much for jumping in to help troubleshoot! I'm using a WD SN850X (in the Framework), and the OS 8 installer successfully partitioned it and seemingly installed, but boots into a black screen. The live environment worked fine, and it's all AMD hardware.
On the ASUS ROG Strix, I'm using a 500GB Intel SSD. That one throws an error the second it starts installing.
Just saw an email from the team saying a few Discord users had problems with AMD.
