5.8 Install claims to work but get grub prompt on boot
#1
I perform a standard install from a USB Image to a small Intel NUC box (8GB memory, couple of CPUs) and when it completes its reboot,and goes back to BIOS, I remove the memory stick and I get the grub prompt. Watching the messages, it claims it's doing the mkboot of sda, and claims to be updating grub but won't boot cleanly after install. I have always selected "wipe config".

FAQ
- It's your hardware / check your BIOS - worked the last 12 times I installed the same image on the same hardware. BIOS boot order is correct (hard drive first, USB second)
- Oh that's easy, just perform [insert 50 grillion commands here] - no, this project is for general public release, they do not have the capacity for 50 grillion commands and besides, it worked before; I need this to be consistent.

I am a Redhat Sysadmin for a living for 20+ years, I have made many custom ISOs and PXE/DHCP boot configs; I know the way OS installs are supposed to work. This OS Install is not working.

Any advice would be appreciated. Regards, Spencer
