So I want to make a dual boot installation with Windows 10 and Ubuntu. In order to do that, I need to install Windows 10 first. The problem is that when I create an installation USB with a Windows 10 image (taken from here) and try to boot from it, I get the following error:
error: unknown filesystem
Entering rescue mode...
grub rescue>
I tried creating an installation USB using dd if=/path/to/windows/installer/image.iso of=/dev/sdd
. I also tried woeusb
utility.
The questions are:
- How do I properly create a Windows 10 USB installer and boot from it, provided that I don't have access to a Windows machine?
- Why do I even get a message from grub? My current understanding is that when you boot from an USB, then whatever bootloader that is on the USB should be used.
