Cannot create recovery usb

#1
Hi
I am in desperate need of help.

I cannot create the windows 8 recovery usb when following the instructions.
I have installed BCD to USB but when I go to add entry the iso fields are greyed out. I have seen a previous thread with the same problem and no resolution or answers.

My Lenovo laptop crashed during updates and I am desperate to fix it.

Any help much appreciated!
Regards
Dave
