i have an Uefi Samsung laptop (300v5a model) i have ubuntu 13.04 running on the whole 640 hdd drive. how can i install win 8.1 now? i want to keep my ubuntu, but as far as ive read, its more problematic than installing ubuntu on a windows machine,
if the problem is with win 8.1 i would install win7. but the question is how?
also, i have Nvidia Optimus. does it matter for this case?
