For The life of me I can not install a UEFI boot image of Linux on AM4 B550M-ITX

So here’s the run down…

I have 2x 5600x CPU’s and can put either CPU in the new Mother Board Asrock B550M-IXT and fails to run thougth the install process of installing Fedora. Both work in a MSI B550 ATX board I have.

The BIOS setting’s used are CSM off, Secure Boot off, TPM off, fTPM on,

As well as CSM on, legacy only and UEFI only, Secure Boot off and on TPM on and off and fTPM on anf off.

I have a ROG B550I and same result.

I have in the past got it install and go to update and get this error

sudo dnf update
Traceback (most recent call last):

ValueError: bad marshal data (unknown type code)

It mainly fails at the install boot loader stage.

Please help

Does it work if you take the fresh install from the MSI board and swap it over to the ASRock board? It might not be a precise answer to your problem, but in the instances where I had issues installing to disk on a particular machine this has always worked for me.

Unfortunately its unstable when I do the swap. It’s got my head spinning, I’ll try my 3700X CPU just to rule out it’s not the 5600X’s.

Try yo use the text based installer and see if that makes a difference Anaconda has aleays been weird in graphical for me and some of the systems that I have installed on.

That was a log I got from Pop O/S GPT had recommend

  • Examine Logs:
  • Review the installation logs for more detailed error messages. It seems like you have logs in the /tmp/distinst.VpxUbgKEdnAf/ directory. Look for any error messages or specific issues during the extraction step.

I’ll get that now… I don’t know what to do with this PC. :woozy_face:

Can you please point me too a good how to guide… I can’t find one too save my life. GPT was no help.

I will look for one. Question: Have you turned off secureboot on that system? Do you have fastboot enabled?

What’s your ram set to, infinity fabric might not like going too fast when set 1:1

Yes secure boot is off and fastboot on.

It’s doing my head in and my wallet. Got a new 5600x Cpu and NVME drive and get the same outcome on the the two ITX boards. :face_with_diagonal_mouth:

3200MHz and have tried auto as well

I’ll take some pic’s

That’s definitely not the problem then, do you have virtualization settings enabled

no virt or 4G decode enabled

I would enable both of them even if you don’t plan on using them, even if it doesn’t fix current problem(it may)

I had a bsod problem and it was caused by a certain program using those extensions and they were disabled

I’ll try






This is the best lead I can get

O/S live boots and works fine. GUI installer runs and fail shortly after.

I have try all boot/BIOS setting on two M-ITX boards.

Have you checked the sha256 sum of the USB/ISO media? In case some file is wonkey?

I reach for memtest86 a nd prime95 when things get weird, they usually explain the issue.
