10 UEFI bootable without GPT, very easy
I was under the impression that it was impossible to boot uefi without having your hdd partitioned using gpt instead of mbr.well, one can't believe everything you read.also, i was under the impression that one had to have the msr partition or the system would not boot.again, one can't believe everything you read.
my bios is native uefi--secure boot is unsupported however in it (turning it off would do the same thing). my hdd drive is mbr partitioned. there is no msr partition. i am booting my uefi windows 10 enterprise x64 this way.
all you need is one regular fat32 partition with the EFI folder from the windows 10 install media copied to it, the bcd edited to point to the windows partition, and viola, uefi windows on mbr.
i did this because i didn't want to wipe and convert my hdd to gpt and my laptop requires uefi to use the dvdrw properly for some reason. and i wanted to see if it could be done, which it can, regardless what everyone else says. this a good workaround for others with hardware not being recognized properly in the newer versions of windows when not running the oem windows configuration.
