My understanding is that there are a few options here. One is to simply re-image the system, either directly (as any vendor does), or after booting off of removable media. I'd have to re-read the spec but some of those might not require signatures, and in any case ones with valid signatures should be available. You can of course disable secure boot or go into custom mode as well which lets you do whatever you want until you have the system back in a bootable state. If you're running Windows 8 I believe they plan to have a recovery partition as well, which will be signed and bootable and which is designed to recover the OS. Rich
