Dear Malcolm,

very likely You face a Windows-10 specific problem. Windows-10 attempts
to implement a quick start procedure by avoiding a full shutdown,
instead using a predefined intermediate state stored on the swap disk
(hibernation). Just try the command from the web page

https://technet.microsoft.com/en-us/library/bb491003.aspx

from one of the Windows-10 command line options (cmd.exe, execute
command Win-Key-Letter-R-Key, Powershell et. al.)

The -f parameter ist critical - pardon, I cannot send You the
commandline, because the virus filter thinks, that I'm sending a virus,
if I use the program name and the parameter...

Any Windows boot process will take significantly more time after that,
but the Linux boot process will succeed...

Yours sincerely

Christoph-Erdmann Pfeiler
