Hello peterzay, The secure boot failure may indicate you don't have it installed on your system. Try running:
sudo apt install ovmf If it is not already installed try running your vm again. Also it may help to enable SATA CDROM 1 in your boot options. Not having it has caused some issues for me in the past. See the screenshot for how to enable this. Otherwise, if both fail, you may want to create a new vm and install Windows 11 from there with TPM2.0, secure boot, and SATA CDROM enabled from the start. ** Attachment added: "boot.png" https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1971509/+attachment/5590088/+files/boot.png ** Changed in: qemu (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971509 Title: qemu/kvm win10 client cannot upgrade to win11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1971509/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
