HP 200 Pro G4 22 all-in-oneLinux Dual Boot Issue – No BIOS Option to Disable Intel VMD / Enable AHCI

[Ghost897]

I am using HP 200 Pro G4 22 All-in-One and I'm trying to dual boot Linux(Zorin OS 18. 1) alongside Windows 11. I've spent a lot of time trying to get this working and I'm stuck.

The problem is that when I boot from a Linux USB, the internal drive is completely invisible. Linux just can't see it at all. After a lot of research I think this is because of the Intel VMD controller that HP uses on this machine.

I've tried everything I can think of — different boot parameters, updating to the latest BIOS — but nothing works. The biggest frustration is that there's no option anywhere in the BIOS to disable VMD or switch to AHCI mode, which is what Linux needs to see the drive.

I'm not trying to remove Windows — I just want both systems on the same machine. This should be a reasonable thing to do in 2025/2026.

Has anyone found a way around this? And is there any chance HP could add a VMD disable option in a future BIOS update? Other manufacturers do offer this and it would make a huge difference for people who want to use Linux.

Any suggestions would be really appreciated!

Thanks

Hi @Ghost897 

That's strange; this model shouldn't use VMD drives, This technology was introduced starting with 11th-generation processors. I suspect you have Intel Optane memory installed, and these modules aren't compatible with any version of Linux.

If you have an Intel Optane drive that has been replaced with an NVMe drive, you can use Linux,
