My B450 Pro4 only boots properly after lots of restart times.
Before that, it does boot into my Ubuntu 18.04.
But when it does boot properly, it seems very stable.
So I do not know if my board problem or OS problem.
Thanks.

Dear Meiyou,

Greetings, this is ASRock TSD.


According to your question, we provide some suggestions for checking if system can always boot smoothly:

1. Please enter BIOS setup and load BIOS default setting via [F9] to verify.

2. Only install bare bone devices; CPU, one stick memory and system disk to check if system can post smoothly.

3. Remove system disk to check if system can always boot into BIOS smoothly.

As AMD official supports Win10 64-bit OS on AM4 platform, for system stable, we would suggest installing Windows 10 for system setup.


Thanks!

All the best,
ASRock TSD

Boot off USB.
Reseat everything.
Don't bother with Windows, ASRock should work fine on Linux.
When it does boot, does dmesg show any errors?
