Here's the problem I have wrestled with for a very long time. Long story short, my PC got some malicious stuff which I tried to remove with program called Malwerebytes. Final result of that it destroyed Windows important registry files and all I got is Windows 10 boot cycle loop forever. In other words Windows doesn't start anymore.
How to Create a Bootable USB Flash Drive for Windows 10 on MAC OS X. How to install Windows 10 on a Mac using Boot Camp Assistant. How to easily create a windows 10/8.1/8/7 installer USB flash drive on Mac OS X. MacOS High Sierra Disk Utility: A Video Walkthrough.
I've tried to create a boot usb with High Sierra that I could run repair install. I have ISO file downloaded from Microsoft and I've been trying couple of online instructions how to make boot usb with Mac High Sierra. They have not worked though and best I get is blinking cursor on my PC screen when I try to boot from usb.
Has anyone succeeded in creating PC bootable Windows usb with High Sierra? Help is urgently needed because my PC contains important work stuff that needs to be recovered. I have made bootable Win10 installers a couple of times in the last month. I use the BootCamp Assistant, which you say does not work for you. I recommend trying the BootCamp assistant again.

Get the screen where you can select Tasks - should be the second screen after BCA launches. Uncheck choices so that ONLY 'Create a Windows 7 or later version install disk' is selected. This is assuming that you have access to a downloaded Windows 10 ISO, and that you have the USB drive that you want to use for the install plugged in to your Mac. I use an 8GB USB flash drive for that. Browse to your Windows 10 ISO, or just drag that ISO to the ISO source line.
Your USB drive should already show as the destination, so click Continue. Wait for that to finish. (My flash drive takes about 30 minutes, so be patient) Boot Camp should ask for your admin password at the completion. You can just Quit Boot Camp Assistant. And, there's your completely Win10 installer drive, all ready to plug in your PC and boot.
You probably have to check in the PC's BIOS to make sure that the BIOS supports booting to a USB device (I can't help you with that!) If Boot Camp does not work for you - does it finish making the USB drive from your downloaded ISO? Do you get some kind of error? If all is OK until you try to boot the PC - do you need to use the boot manager for booting to USB? Again, double-check the boot options in the PCs BIOS setup screens, make sure that USB booting is supported (and enabled, if necessary).
If you have the ISO, get a flash drive at least 8GB like others have stated. Open terminal and type 'diskutil list' and get the disk identifier for your flash drive. It will be listed next to the current name of the drive and whatever size it is. It will say like 'disk 2' or 'disk 3.'
Just make ABSOLUTE SURE you get the correct one. If you would like, post a screenshot of your results so we get the right thing. Next, type 'diskutil unmountdisk diskX' followed by 'sudo dd if=PathToWinISO of=/dev/diskX' where diskX is what you identified above.
Also, after 'if=' you can drag the ISO into the terminal window and it will fill out the path for you. This will take a while, so let it run until you see it say completed and some stuff about how long the transfer took. If you have the ISO, get a flash drive at least 8GB like others have stated.

This will take a while, so let it run until you see it say completed and some stuff about how long the transfer took. If you used your Boot Camp assistant to create the bootable USB drive from a Windows ISO, Restart your Mac, holding the Option key.
The boot picker screen will appear. Insert your USB Windows installer, and you should see TWO possible boot partitions appear. One will be Windows, and the other will be EFI Boot. The one that works depends on which Mac you have. Some Macs may need quite some time to respond with that boot to the Windows installer, so give it a few minutes for something to happen.
USUALLY, at some point, you will see a screen to 'Press any key to boot from disk'. I think if you ignore that message, the boot will stall, so watch for that screen. It does not appear in all cases, but you should watch for it, so you can press a key. Or, it will continue on to where you can install Windows, and from there it's pretty straightforward. I ALWAYS choose a custom install, so I can format the Windows partition that boot camp creates. The Windows installer might stall there, too.
So after a format, I usually shutdown there, then restart to the Windows installer. And it usually goes through without a hitch.
