What is exactly your problem? Does it boot, you see xen/linux messages but fail before asking for your luks passphrase? Maybe it is just a linux kernel problem and you can boot an older version editing xen.cfg (if you are using UEFI boot without grub). Do you have installed kernel-latest versions? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
