I wonder if anybody could help.

I have 3 operating systems running on my pc

1 - Windows 7 SSD internal drive
1 - Windows 7 internal Sata drive
1 - Windows 8.1 (Full) external USB HDD

The problem I have is when I turn the external drive on and try to boot to windows 8 the following error appears
Winload.exe error oxc000000E

I have used the windows 8.1 installation disk to try and repair but to no avail.

Everything worked fine until a few days ago. I have made no hardware changes to my system.

I use easy bcd to enable me to select the operating system to use.

Many thanks
