QubesOS not working on Lenovo Legion 5 17ACH6

I’ve been trying to install QubesOS (4.2.4) on a laptop (Lenovo Legion 5 17ACH6) but everytime I install it it would ask me to enter the decryption password, i enter it, then it would boot into a black screen for like 5 seconds or so and then shuts down itself and reboot again and it keeps doing so forever, i disabled secure boot, enabled AMD-V, and i have 32gb of RAM and installed it on an empty 256gb SSD, so what to do now? i also used this command to burn the iso on a usb:

sudo dd if=Qubes-R4.2.4-x86_64.iso of=/dev/sda status=progress bs=1048576 conv=fsync

Try installation with kernel-latest.

After entering the password, can you press ESCAPE to show the boot log? Does anything jump out? Any errors? Recording the screen with a camera may help

this is what happens (sorry for the bad quality)

Hi user8168 - and welcome to the forum

Would you be willing to test Qubes OS R4.3-RC1? - it’s the 1st Release Candidate for R4.3, so it’s not as stable/tested as Qubes OS R4.2.4 … but it has a lot of updates for recent hardware.

From the video you shared, it looks like the “Initial Setup” that crashes - have you tried to blacklist the Nvidia driver by editing the GRUB menu and replacing

quiet

with

nomodeset modprobe.blacklist=nouveau

when you run the installer?

installed the latest stable release, chose the latest kernel, edited GRUB (replaced ‘quiet’ with ‘nomodeset modprobe.blacklist=nouveau’), i booted with F10 then it asked me to ENTER to continue, when i clicked nothing happened for minutes and it printed ‘Pane is dead (status 1, Mon Aug 25 10:42:10 2025)’

Hi user8168

Okay - so the installer doesn’t like the nomodeset modprobe.blacklist=nouveau – if you still have the installation on the drive, could you try to edit the installed GRUB menu?

Yes I can

If you can edit the installed GRUB, please share if it changes anything.

If the machine still reboots, could you try to add:

console=vga vga=,keep loglvl=all guest_loglvl=all noreboot=1 earlyprintk=xen

to the Xen-line in GRUB - and share the result?

thid is what happened, it froze at the end there, (version 2.4.2 with the latest kernel)

Hi user8168

I didn’t see the video - but it makes sense that it “froze” … the

console=vga vga=,keep loglvl=all guest_loglvl=all noreboot=1 earlyprintk=xen

tells Xen to print a lot of debug … and “don’t reboot, but keep the text on the screen” to enable some debugging. So it should be possible to share an image of the result (?).

sorry if i’m being annoying, but i just don’t understand what you just said and i’m confused, i downloaded Qubes version 4.2.4 with the latest kernel to an empty SSD and now can boot into it, now what?

Hi user8168

From my point of view, you are not annoying … you simply have an issue with the installer and asks for suggestions/recommendation. :slight_smile:

It’s unclear to me, if you tried the 4.3RC1 – I have a Lenovo ThinkPad T14 Gen 3[1] with a Ryzen™ 5 PRO 6650U and AMD Radeon™ 660M GPU and with Qubes OS 4.1 and Qubes OS 4.2, it behaved similar to what you describe.

At some point I started testing the weekly builds … and in May it got to the point that I could actually install a weekly build on it. :slight_smile:

I still have issues with the WiFi (according to lspci it should be a Qualcomm QCNFA765) so I resort to a USB dongle, when I need network connectivity. :-/

On that basis, I would suggest that you try the Qubes OS 4.3RC1 and share how it works.
