Windows media creation tool error 0x80004005 - 0xa001a

Hi, Since the Fall update I have had nothing but problems with a bootable USB drive. Windows media creation tool returns an error 0x80004005 - 0xa001a, which the internet seems oblivious too and the windows 7 USB/DVD download tool creates a drive which is none bootable. 

I spoke to microsoft who advised me to download the windows 10 ISO and use the windows 7 USB/DVD download tool to create the media but it failed to boot.

I searched online for solutions as to why windows 7 USB/DVD download tool would not create a bootable USB drive from a windows 7 ISO and I was given directions to use Diskpart. This also failed.

So does anyone have any solutions to fix the 0x80004005 - 0xa001a error with the media creation tool.

I also tried both windows 7 and windows 10 USB Drive in 2 systems and neither would boot the windows install program.

Thanks Baz


Thanks but unfortunately this did not work.

I have however managed to get windows 10 to boot on a USB drive.

I did a low level format and used diskpart and the powershell to set up the USB drive and copy the files to it from the ISO.
