 0xC1900101 - 0x30018 - The installation failed in the FIRST_BOOT phase with an error during SYSPREP operation"
I've attempted to install windows 10 half a dozen times now, these are the steps I’ve tried.
1.	Changing my location setting to US in all areas apart from Keyboard.
2.	Set the update available Registry Key to (1) rather than (2):
No luck..
My next step it to try Andre’s reply to this thread that Sangeeta initially replied to, her reply of which was so very, very helpful…

If anyone else has had these issues and found a fix or managed to install Win10 go ahead and holla!
