I have an INTEL NUC Intel Celeron CPU 847 @ 1.10GHz. The box has 4G ram.

I tried many times to install Kali Linux 2021.3a on the box. It never would boot. I looked as if the boot sector had not been installed. It works fine from the USB. This tells me the hardware is compatible.

I sniffed around reddit but couldn't reach any conclusions.

Tried Ubuntu 20.04 - worked perfectly. Not a single issue!

Any suggestions? I really would like to have Kali on that box.
