Cannot boot 4.1.0 medium

[Ulrich Windl]

Hi!


I downloaded and checked the Qubes OS 4.1.0 image and wrote it onto an USB stick.
When inserting the stick to boot (on a different computer), I'm offered UEFI boot and normal boot by BIOS.


"Nice, UEFI" I thought, but somehow that does not work (see attachment). Well, I think UEFI boot should work for Qubes OS, too as Tails has a working UEFI for quite some time now, and legacy boot is increasingly rarely supported on new hardware (IMHO).


OK, trying the other (compatibility) mode, boot also failed (see other attachment).


Now I wonder: Is my stick defective, did I have a write error, or is the image defective?


Regards,
Ulrich

Hi,

IMHO you should first check if the image on your USB stick is broken. See

I guess the magic number count=5199888384 is different for 4.1.0 ;-)


Despite at first sight I'd say it doesn't look corrupted:

I'll try to investigate and report back. Unfortunately I don't have the original image here right now.

Yes. It is the size of the appropriate ISO file. For R4.1.0, it should
be 5954863104.

Maybe you catched nothing bad by listing files. Maybe the files
themselves are corrupted. Who knows …
