After update of Fedora 36 to Fedora 37, VirtualBox host has been updated to 7.0.4, and now both of VM Win8.1 and W10 display black screen when starting. I suspect it could be VirtualBox Guest Additions drivers being still older after update.
Anyone knows how to uninstall Guest Additions from CMD. I've done rescue mode and tried Start-up in Safe mode but no luck so far.
From CMD I went to

Code: Select all   Expand viewCollapse view

 c:\Program Files\Oracle\VirtualBox Guest Additions\

and tried to run

Code: Select all   Expand viewCollapse view

uninst.exe

, but it doesn't work as it is GUI program.
I've found some tip to do

Code: Select all   Expand viewCollapse view

pnputil.exe -i -a *.inf

, but it didn't solve the problem, it actually, as it seems, install drivers from that folder, rather than remove it
Any other clues?

Was this problem solved by applying fth0's instructions, as you reported here? viewtopic.php?f=2&t=107519&p=528743#p528743

Yes I've solved the issue with disabling SVGA via comand:

Code: Select all   Expand viewCollapse view

VBoxManage setextradata "VM name" "VBoxInternal/Devices/vga/0/Config/VMSVGA10" "0"


Then I was able to:

- boot into windows,
- remove old Guest Additions,
- download new Guest Additions v 7.0.4,
- install new Guest Additions
- reboot, and enable SVGA again

and all is working like it should
