I have a strange situation where my machine wont post grub. It happens randomly and just restarting the machine seems to solve it. I have a z390 pro mobo, Boot logs seem clear. Other times grub is extremely slow.
The machine does not experience any hangs nor crashes and I seem to be affected just on boot/reboot. I have found similar reports. Ideas?
