Could this be a Secure Boot or drive partition type MBR vs GPT (GPT needed for UEFI) problem from the previous install? The GPU boot beep error doesn't make me think so, but worth a check. Also, have you tried:
A) Use different display cable, HDMI / DisplayPort or a different display?
B) Plug in only one of the GPU power connectors if your GPU uses two connectors and see if any messages appear stating to plug in the power cable?
C) Spam F2 or Delete key at boot?
D) Disconnect all drives and try booting from W10 Install USB ISO?
What does System Information in W10, msinfo32, show for BIOS Mode and Secure Boot State?
