I have yet to understand that "Feature"
As the "Sources" Folder containing the "Setup Files" is inside the Boot.wim (X"\Drive)
Where normally those Files would be located on Media (Y:\Drive)
Also Missing from the Media is the Install.wim...
So the work around others use is to Copy The Contents of the Setup Media ISO To USB
Then Copy the Contents of the Win10XPE ISO the USB (allow overwrite of existing Files)
To run Windows "Setup" just browse to Y:\Sources\Setup.exe
Or Edit Pecmd.ini via > Build Core/Main Interface/Edit Pecmd.ini Button
From
LINK %Desktop%\Windows Installer,%SystemDrive%\setup.exe
LINK %Programs%\System Tools\Windows Installer,%SystemDrive%\setup.exe
To
LINK %Desktop%\Windows Installer,Y:\Sources\setup.exe
LINK %Programs%\System Tools\Windows Installer,Y:\Sources\setup.exe
After checking to give advise to Shortcut to Y:\Sources\Setup.exe
The Current Shortcut appears incorrect - as the "sources" folder is not named after systemdrive....
Although remember the Install.wim is not present
