Well I think on every Board it's an adventure to fix the error 43 😅 That was all I know, hope you find the solution soon!

ok, then leave it in UEFI mode and just switch this "Other PCI Device ROM Priority" setting to Legacy, maybe this also works.

Ok found the settings wich prevented me from installing the driver. 1. I switched back to Legacy Mode in the flash settings from Unraid 2. Go to the bios and Seach something like "Other PCI Device ROM Priority" and select Legacy only. Then I reinstalled the graphics driver in the VM and now it works again. Hope this time it helps

No, I read an article where someone said you can fill the vendor_id up with 12 random characters from 0-F. But funny thing, I played around and now the error 43 is back I will let you know when I found that one option wich fixed the error for me

Hey I think I solved my Error 43 with changing and adding some lines in the xml file: first at the vendor_id type in a 12characters long ID Example: 2D76A8B352F1 then add the rest, it should end above the features closing bracket. So the idea is to hide the VM for Nvidia, because the driver don't want to be installed on a VM I think. <vendor_id state='on' value='2D76A8B352F1'/> </hyperv> <kvm> <hidden state='on'/> </kvm> <ioapic driver='kvm'/> </features> Hope it helps
