Proxmox2: No bootable device

I faced this problem moving KVM machines from Proxmox 1.9 to 2.0 with SCSI drives having the issue «No bootable device» and after some hours wasted I could find a very easy way to fix this:

– Restore backup from froxmox 1.x, move to new proxmox 2.x
– Delete the disk from Proxmox admin web panel
– Mark and edit the «unused disk» that will appear in the hardware devices
– Add it just as a IDE drive
– Enjoy

Hope this helps ,-)

Cheers !!! 😉
