As I was preparing to head out to the Ubuntu Oregon Ocelot 11.10 Release Party the other night I received a e-mail from a LoCo member in Salem, Oregon who passed on this message and felt it was an important matter to begin discussing:
Recent articles regarding UEFI and Windows 8 suggest the problem of the former blocking Linux bootloader installation is a matter that will appear at the introduction of the latter. That is not the case. It is on Win 7 machines and blocking GRUB installation now.
My friend recently got an HP s5-1110 with Win 7 installed. UEFI has prevented the installation of GRUB on this machine. I could find no way in the BIOS to disable the feature and so far, as I work my way up the HP tech support ladder, I have found no HP techs who have a clue what I’m talking about.
