I can't tell without booting that, there are both grub and isolinux directories on that image (debian-live-10.7.0-amd64-standard.iso that is.) >> 7-RMA the 5700. > > I'd be extremely hesitant to do that unless I know it's the problem. > Also, although I just unboxed this within the past week, I ordered it > more than a month ago; it's entirely possible they might not accept it > back now. Well, it does have warranty, no? I'd say "I can get into BIOS all right but if I try to install Windows 10 I just get a black screen. Everything works fine with my old video card." Of course you'd want to test with Windows first but to me that's a sufficient diagnosis from a consumer. After all, at https://www.amd.com/en/support/graphics/amd-radeon-5700-series/amd-radeon-rx-5700-series/amd-radeon-rx-5700-xt#amd_support_product_spec AMD only lists sufficient power as a requirement. PCI express versions are compatible with adjacent versions and I think you have PCI express 3.0 on your motherboard & CPU. Still, I wouldn't mention Grub, Linux or the age of your hardware in a warranty claim. Of course, if you get a replacement and the new card doesn't work in your system either then it's more likely to be an incompatibility problem.
