I was having a similar problem where my Windows 10 vm, using SeaBIOS and GPU passthrough, wouldn't boot after ugrading Unraid to 6.10. Switching from GPU passthrough to VNC allowed me to boot the VM. I was able to solve this issue by using OVMF instead of SeaBIOS. To convert my Windows 10 VM from SeaBIOS to OVMF I first booted using VNC and then followed the instruction on this thread to convert my VM from SeaBIOS to OVMF. Don't forget to first make a backup of your vdisk image so you can restore it if anything goes wrong. When I first ran these instruction I got a "MBR2GPT: Cannot find OS partition(s) for disk 0" message. In case someone has the same issue, I solved this with the following steps Run CMD as administrator run "bcdedit" Under the "Windows Boot Loader" section copy the recoverysequence run "bcdedit /delete your_recoverysequence"
