Re: I wonder how well this would run Linux?
"Let's have a guess if they want their hardware running revenue-producing OS to run another OS."
If you buy a Surface Book, you've already paid for Windows 10 as part of the price of the hardware.
Also, a question from someone who is ignorant on the ins and outs of UEFI, but surely the point of secure boot from a trusted source is that you don't allow any applications on the OS (which for all UEFI knows could be malware) to change anything in UEFI / boot sequence.
So how come Windows 10 updates can reconfigure UEFI to ignore or remove a Linux partition and default again to Windows 10?
