Qubes 4 won't boot on Thinkpad T430

[Ha L]

Hello everyone,

I'm having trouble booting Qubes 4 on Thinkpad T430. I managed to install Qubes 4 by turning off VT-d in the BIOS. If VT-d is turned on in the BIOS then Qubes simply does not boot.

I have tried to add 'iommu=no-igfx' option, I have removed it completely, I have also tried 'iommu=on' and 'iommu=force'. Nothing seems to work.

Prior to Qubes 4, I was able to boot Qubes. 

Any help is appreciated, thank you all.

Does your T430 have Nvidia graphics? If so, you could try turning it off
in the BIOS.

Also, you should try updating your BIOS if you haven't recently.

Thanks for the reply Chris.

I don't have dedicated graphics and I have also updated the BIOS to the latest version. It's still not working.

You might check out this working HCL report for the T430 (subject has a
typo):

Other variables here might be the specific CPU, chipset, model# and
options, dock, etc.

Also check the system self-test, and see if resetting BIOS settings to
defaults helps.

Greetings,

I can report that i was able to install (and boot) the Qubes 4 final without any problems out of the box (no extra boot option) on my Lenovo Thinkpad T430, while installing Qubes 4 from an external dvd drive.

The same notebook already worked without problems with qubes 3.2 final. i did not change any bios settings meanwhile.
in bios, i enabled both vt options.

all the best
Kai
