Hi Sam, just as a disclaimer: I did not test any Windows 8 boot process yet so it is all "mind games" based on my understanding, after reading a bit here and there - hopefully the right bits and nothing misleading. On Thu, 13 Dec 2012, Sam Varghese wrote:
From my personal experience, you can only have Windows 8 and Ubuntu on the same machine on separate drives [2]. This install was done in the bog standard way.

"But you cannot install Ubuntu 12.10 64-bit on a Windows 8 secure boot machine which has a single hard drive." That makes sense, if you tell your machine to boot just what is signed, you cannot slip in a boot loader the machine does not know. So working as expected? Well, obviously there are ways around it, e.g. if the Windows 8 boot loader allows you to boot another OS from another partition. Former versions could, and it looks as it is still there. Hyper-V may give you another way to break free.. Anyway, you describe how to switch on the secure boot in the UEFI BIOS. http://www.itwire.com/opinion-and-analysis/open-sauce/57562-installing-windo... Just turn it off and install Ubuntu as usual? BTW: Can you still boot the Windows 8 installed with secure boot? (Obviously not the other way around, turning on secure boot broke the Windows 8 installed without secure boot, as you wrote). I find it odd that there seemed to be no way to put a key in manually. E.g. create a key, sign your new kernel with it, boot into UEFI BIOS and hammer it in. If it is a place which is read-only outside the UEFI setup, it should be safe and serve the purpose: Don't let me boot a kernel I did not want on my machine. Or did I overlook something? Regards Peter
