How to make windows 10 bootable usb under Ubuntu when even mkusb didn't help?

I tried from the command line, i tried mkusb, since i read windows 10 can't be made the old way, but it still doesn't boot it.

I'm with Ubuntu 17.04, want to make windows 10 bootable USB to boot it on a macbookpro that is with grub and old ubuntu.

I want to wipe the whole hdd, since ill be repurposing it for someone else.

You should check that the image is intact by running a checksum. This answer describes how you can get a checksum from Microsoft. (I can't confirm that's how to find it, since I don't have an MSDN account.) You'll want to run sha1sum path/to/image.iso and compare the result to Microsoft's checksum. "path/to/image.iso" should be replaced with the location/name of your image. If they provide something like and MD5 or SHA256 checksum, then you'd run md5sum or sha256sum.

If you think mkusb may not be working, you could just flash the image directly using dd. The command would be sudo dd bs=4M if=path/to/image.iso of=/dev/sdx, where /dev/sdx is the USB device you want to copy to. You can find that by unplugging the USB drive, running lsblk, pluggin the USB in, and running lsblk again. The device that shows up in the second output of lsblk but not the first is your USB device. (It's also worth comparing the drive size and name. lsblk should tell you the size by default and the name if it's mounted.) Please note that you should really try to use a higher-level tool like mkusb or unetbootin first. From what I understand, dd copies byte-for-byte, ignoring partition headers. Whatever device you specify in the of= argument will become Windows, even if that's the drive your OS is on.

Since you're installing on a Macbook, it would also be worth checking that this image can be installed on there and that it's able to live-boot.

Sorry, I don't have the rep to comment directly. (Seems so backwards...)
