Boot Entry Disappear after Disk removal

Hi folks, after I use KVM dual boot with hardware switch, I’ve found a new issue, after installing Qubes everything works but once I turn off the disk and boot up and shut down, the Qubes boot entry disappear, I’ve check the disk, everything still there, but the entry is gone. and I’ve seen official documents UEFI Troubleshooting, I didn’t try it yet, I am not sure, but the workaround seems will broke after updates, I am worry about that workaround would trick myself boot into old Xen after updates, is that workaround safe? or are there any other workarounds?

Known issue, the fix is in the testing repository and should be in stable repository soon so it won’t happen again:

For now you can fix it like this:


That fixes the issue, Thanks for your help!
