I get this message saying "read error" in the VM bios screen. I have reverted back to 6.9.2 Hi, there was another case about another user having bcd boot error (it was a windows 10 vm) when trying to boot from the nvme; bare metal boot was working. He was using seabios too, as you. He was using unraid 6.10.1 This case seems similar to yours and maybe it can be solved the same way: https://forums.unraid.net/topic/124021-win-10-vm-bootbcd-io-error-after-unraid-6101-update/ I compiled the latest version of seabios (1.16.0-4-gdc88f9b), maybe you can try this. Extract file bios.bin from the zip and save it somewhere on unraid (i.e. /path/to/bios.bin). Open the vm settings in xml view and change from: <os> <type arch='x86_64' machine='pc-q35-5.1'>hvm</type> </os> to: <os> <type arch='x86_64' machine='pc-q35-5.1'>hvm</type> <loader type='rom'>/path/to/bios.bin</loader> <boot dev='hd'/> <bootmenu enable='yes' timeout='30000'/> </os> Try to boot.

Solution GreedyChip Posted June 25, 2022 Author Solution Share Posted June 25, 2022 Converted My Ubuntu install to a UEFI one. lucky my GT710 has UEFI support had to reinstall the NVIDIA drivers to get the display working again. Quote Link to comment
