I did a quick test and installed on a small hard drive and it installed without any problems. So the issue is the large 2tb drive preventing the install. Dwight

The hard drives were Western Digital: WD10EURX for the 1tb and WD20EZBX for the 2tb. In the meantime, I got a disk copier software and copied the 1 tb to the 2tb and then copied the correct EFI to the drive and everything is working fine with the larger drive. Just need to know why I was having problems with the install. I was tired when I posted and mistakenly said 2 gb drives. , Dwight

This past weekend I was successful in installing Big Sur on my Gigabyte Aorus Z490 computer with a i9 10900 CPU and a Radeon RX 480 GPU. I installed the OS on a 1gb test hard drive and everything worked from all of the USB ports, the sound, Bluetooth, sleep and Wi-Fi. I was very happy that this all worked on the first try without a lot of tinkering. Thanks very much. Now I am trying to install on a larger 2gb hard drive but the install is stopping at the Apple logo on a black screen with the time counting down from 24 minutes to zero minutes but it stops there, does not boot any further. Nothing has changed except trying the same install thumb drive with a larger hard drive. I am using the correct Cometlake EFI, which worked when I installed it the first time. Not sure what to do now. Thanks for any help you can provide. Dwight
