Bootcamp issues on imac pro high sierra mid 2010s

So a normal hard copy of a windows 8.1 disc will work? I put the disc in my mac and just like that windows 8 installs? I find it insane that I have not seen anyone suggest that method it'ts so easy. Thanks.

Hi, I'm sure your solution will work for everyone else but my Mac is scuffed. I finally figured out how to use the bootable usb. I booted windows 8.1 typed in the licence key etc but it did not let me partition my drive. I then watched many tutorials on how to partition a windows format drive etc but it simply will not work I get every error message under the sun. I will have to send my mac into a store when possible :(

I'm getting this error on Bootcamp: ''Your disk could not be partitioned. An error occurred while partitioning the disk. Please run Disk Utility to check and fix the error''. The only solution I have not tried is erasing/repairing the disk in the bios - The Mac has over 500gb of super important files on there and I nearly had a heart attack when I erased one of the external hard drives by accident but thankfully it was backed up in the internal documents. I can't try any repair solutions that risks deleting everything.

Another error is on the windows 8.1 bootable usb start up I cannot remember it exactly but there's an easy solution where you simply run cmd and clear disk, which once again I cannot do as it risks erasing everything. I give up bro :D thanks for trying unless you're a God and have some sort of solution. I have tried for 3 days now, every forum/video under the sun. My disks just doesn't want to partition I am guessing I just need to erase/repair all my disks in the startup terminal bios menu (if im saying that correctly) but I can't the Mac is not mine.

If I try booting windows 8.1 via a disk will it still ask me to partition my hard drive? because that is where it is failing

when i go to disk utility I have Macintosh HD, FUSION and my external drives. Nothing else shows
