New PC build but Linux will not boot correctly

[RobGoss]

Hello I just finished a new computer build it's a Ryzen 5, 3600, I tried booting a USB of Ubuntu mate but nothing will boot, I even tried booting Ubuntu mate from a SSD I have installed on this machine

I have two hard drives installed in this machine. I did install a hard drive with Windows 10, and everything seems to work ok. Could it be something in my BIO that's stopping Ubuntu mate from booting. The mother board I have is a Aorus B450 Pro Wifi if this will help

Thanks so much

Have you tried a different USB port (One attached to the motherboard)?
Did you set the BIOS to boot USB first?
Does the BIOS show the USB stick when you navigate within setup?
Does the Ubuntu USB stick boot in other systems?
Did you MD5 test the ISO you downloaded?

Yes I did just about everything you mentioned but still can't get Ubuntu to boot correctly. The usb I used works fine in my other machines. I'm thinking maybe the bios needs flashing but Windows runs fine not sure what it is. Ubuntu will boot at one point but them it just hangs at the boot screen

Thanks

There are a number of BIOS changes needed to boot non-MSFT operating systems. Read the manual and there is a "ubuntu uefi" guide that google finds easily with other tips.

Definitetly check for firmware updates, for both the motherboard and SSD. Try the latest kernel, 20.10, or even the daily build of 2104.

Often UEFI and if SSD, SSD firmware updates are required. You may need them even if new system.

try usb 2.0 port not on 3.0 ports as it always looks for its driver when using it maybe it will help.

With Ryzen, there are a few needed things that Intel CPUs didn't usually need.
Always flash the MB firmware, especially when using a Ryzen 3K on a B4xx motherboard. There are many reasons for this, but mainly compatibility with newer parts.
Depending on the RAM used, you may need to check the speed. I've had to slow down by 3200Mhz RAM to 2800 Mhz to get a stable system. The XMP (D.O.H.C.) RAM settings weren't stable. Also had to relax two of the main RAM settings and verify that the voltage was slightly higher. With 2 sticks, it wasn't this hard, but when I filled all 4 RAM slots, it became more picky.

There are multiple settings that are for Windows and UEFI. Those are recommended to be disabled. Read the motherboard manual. I have no idea how someone is supposed to dual boot without using 2 different BIOS profiles. Fortunately, many current motherboards support having 4 different BIOS hardware profiles, but I don't know about your specific MB or BIOS.

I spent a few hours searching motherboard tweaking sights to find all the settings. Unfortunately, most will be for OC and gamers on Windows.

This is my second Ryzen build the first one runs just fine I can boot Linux and Windows with out having to update the BIOS, I thinking it 's just this motherboard that might need tweaking, oh and by the way the motherboards are the same in brand but this last one has much more features

I am currently running BIOS 51, and when I did a bit of searching I believe 61, is available at the moment....
