Yes, I'd forgotten that - Sorry.
It boots you into the advanced boot options and then you need to use your cursor keys to select and then press enter.
I've had a reply from Shane re the 76% hang and while it is difficult to diagnose, he's replied with -
"If it is at the "Loading Windows Variables..." point then that is where it makes calls to the system to get the variables such as all the folder paths, the current user sid, the machine ID and such.
The only thing in that whole section that does any kind of loop would be the get machine ID command. Which calls WMI first and then the WinNT command if wmi fails. Both of those have loop commands, I wonder if something is messed up on his system that is causing an error and so the loops never end.
I am making an update that I will put out tomorrow, in it I will have a command to where if the loops go over a certain amount they will stop, and we can see if that does the trick for him".
So have a look out for the new version tomorrow
