Ultimate Edition Forum

I recently bought a new Samsung notebook with windows 8.1 and want to install Ultimate Edition alongside of windows but want to ask a few questions before making the attempt. So messing around in the bios I have the option to disable safe boot which I have and the pc still boots fine. I have 3 mode options to boot to UEFI Os, UEFI & Legacy Os, and CSM Os. Upon trying the different options the computer will only boot when set to UEFI Os. The other 2 selections just give me the black screen asking to insert a systems disk! Once I install Ultimate Edition and shrink the primary windows partition will I leave this setting alone or will I need to change it to UEFI & Legacy Os? I've done some research but am unclear on how this will turn out. I do understand that safe boot must be disabled but is grub going to be able to chainload the windows 8 os?

Perhaps this guide may help you? Not tried it myself yet - my laptop much too old!

Thanks megaptera. that's a good read but not what i'm looking for. my main concern was with the resizing of the windows partition. wondering if doing so will affect the key. not sure how the key works. if it's like a md5 checksum I would assume resizing the partition may affect it!
