"Setup was unable to create a new system partition...."

"https://technet.microsoft.com/en-us/library/hh304353(v=ws.10).aspx"

Is following all these steps necessary?

I've now formatted the USB exactly as you told me, this time choosing FAT32. It froze again at the "Starting Windows" logo.

Could it be that there's something UEFI incompatible about my hardware? I mean I doubt it but I simply have no clue what's wrong with it

I've formatted the USB back to MBR and this time it goes past the Starting Windows screen. Why would UEFI mode be a problem for it?

I've deleted the partition, and created a new one. This time it's listed as primary but it still gives me the intial error.

you delete the partition leave it blank let windows create what it needs you have no space to create a parition

Hi,
Legacy boot has to be enabled.
Post some pictures of the bios options you have
Mostly boot and os type this will need to have an option for other os

You also need to make sure the hdd = hard drive is not formatted gpt and it needs to be mbr if it is gpt you'll have to install with uefi.

Legacy boot has to be enabled.

What for? I know it has to be disabled to be able to boot in UEFI mode. I enabled it back on because I've dropped it and decided to do it in regular BIOS.

The only descriptions I can find are "Insyde H20, version f.1b"

It's not formatted as anything. It's not marked as either GPT or MBR when I check it out in cmd.

It is. I've tried doing it manually once again by using the xcopy command in cmd. Instead of copying everything it only copied like 4 files and created a system partition with 910 gb of space, and an unallocated one with about 20gb left lol.

I honestly have no clue what to do anymore.
