Matthew Garrett, a.k.a. UEFI-guru, has revealed that those who are keeping their fingers crossed and hoping to find run Linux on Microsoft’s tablet are on an uphill walk and it doesn’t seem to be an easy one. So why is this? The answer is in the manner in which Microsoft has restricted the Surface from loading non-signed software / binaries by implementing UEFI SecureBoot. Microsoft has loaded its private key instead of the "Microsoft Windows UEFI Driver Publisher" key on the ARM based tablet, which is needed to sign non-Microsoft software like Linux distributions or loaders. So, no publisher key = no signed non-Microsoft binary = no Linux.
