The most reliable and hassle-free way of making Windows install USB flash drive from an ISO I’ve found is using Rufus under Windows (on another machine under Windows, for example).

There’s also official windows program to do the same:

I’ve used it to create Windows 7 bootable DVD, but had trouble with Win10.

Just for the broadening our perspectives, so to say, I’m quite sure I’ve used this recipe once successfully:
linux - Fedora: Create windows 8.1 bootable USB - Super User
I don’t think it’ll work with win7 though (but again, I’m not sure). I think it works with UEFI boot only (that’s why just unpacking files on a fat32 partition is enough, as suggested). Also I think it worked with earlier Win10 version for me, but a later one had an installation file more that 4 GB in size – and that couldn’t be written to or read from a fat32 partition. Again, not 100% sure, as I’ve tried it quite some time ago.

Here’s another guide – with more details/explanations along the similar lines but using ntfs partition instead of fat32 one, and I think it’s good for BIOS boot. I haven’t tried / verified this one myself.

I’ve tried WoeUSB myself – right now – and it created a Win7 USB for me without any errors. Moreover, I’ve tested it, and it booted successfully in BIOS mode.
We can try to troubleshoot it erroring out in your case – if you want. I think)
It also has it’s own github repo:
And there’s a wiki there too, although I haven’t seen you particular error there (but I wasn’t very thorough, just looked briefly).
One bit of useful information from the wiki regading hybrid iso discussion above:
Why Not Just Using
dd
orcp
?Windows Installation Disk Images aren’t Hybrid ISOs , thus they won’t make USB storage bootable if it is rawly-written.
