Hi,
My asrock h110 pro btc+ hangs on reboot when bootable usb is plugged in.
It just stops on asrock logo page. When i take out usb, it starts. When not, it hangs. Only hard reset helps. But then it enters bios itself.
Any ideas ?
On ssd W10 no such thing.
How many GPUs are you running on this MOB?
What is the model number of the CPU installed? Low end Celeron CPU can cause problems with H110 Pro BTC+ MOB.
