I made a terrible mistake today. Some features like sound didn’t work inside virtualized standalone windows and I was trying to find a way to fix it. I created a separate service qube and in device settings toggled all available devices in that qube. I tried to start windows with this service qube but couldn’t. Then I tried restarting the computer but after I entered the disk password I got just a black screen and the computer shut down by itself, I tried turning it on again but now every time I get just a black screen.….
I am writing this with trembling hands because this computer had very important accounts that I can’t access anywhere else. PLEASE TELL ME WHAT CAN BE DONE TO FIX THIS OR AT LEAST SAVE THE DATA.
On system startup before entering disk password you will get an option to start Qubes , click “e” letter on keyboard before it manages to reach the disk password prompt, clicking ‘e’ will open the grub boot parameters screen , scroll down with ‘down’ button until you find something like “rhgb quiet”, add the following after it directly ( this will prevent the problematic VM from autostarting if that’s causing the issue) :
qubes.skip_autostart
only If you are on desktop , not a laptop and are using a USB keyboard then you may need to remove this line mentioned below to accept keyboard in dom0 so you can enter disk password as you have done before ,
In that case , Remove the following :
rd.qubes.hide_all_usb
Now that you have added this and removed the second mentioned line , clickF10 button on keyboard to start Qubes normally, enter Qubes and don’t start the qube that you assigned devices too, instead remove these devices by navigating to qubes manager and selecting the settings (same place you assigned them in)
NOTE : removing the second line is probably not needed and that step is better skipped, unless the desktop wouldn’t allow you to type passwords , which i think isn’t the case.
