Boot to WinPE from primary drive boot menu

[Anakunda]

Hi, is somehow realizable adding ISO image which is Windows PE, to be a valid entry for Windows boot menu (BCD store) ?
I need to boot WinPE without using USB stick or optical media but don't know how. Thanks

You can Boot Into WinPE/RE via Your Boot Menu
By coping the contents of the ISO into a Folder or to a Partition

And then run a batch of bcdedit commands..

So question is - where is the Boot.wim located...
