If I attach PCI devices (2 USB controllers) to my Windows 10 standalone HVM it fails to boot with error:
Booting from Hard Disk…
Boot failed: could not read the boot disk
No bootable device.
How can I fix this? Is this a known issue?
Background: goal is to back up an iPhone. On R4.0 I succesfully used a Windows 10 VM with attached USB controllers (via qube settings/PCI devices). Now I tried to recreate this on R4.1.1. Installing new Windows 10 standalone VMs and Qubes Windows Tools according to the official guides worked great. But when I attach a PCI device I get the above error.
Further details: the error occurs for Windows 10 VMs with and without QWT installed. If I remove the USB controllers from the VMs they boot just fine. Same error also occurs with an old Windows 7 standalone VM. Strict PCI reset is disabled.
Thanks for any thoughts!
