C:\Windows\system32>bcdedit -create -application osloader /d "WinPE"
The entry {e130d653-5b23-11df-aac2-bac3ae784ab1} was successfully created.

^ randomly generated number, thats the WinPE GUID, edit out the %WinPE
GUID% accordingly


bcdedit says:
Many of the Bcdedit commands require identifiers. An identifier
uniquely identifies entries contained in the store. An identifier takes the
form of a globally unique identifier, or GUID. A GUID has the following format,
where each "x" represents a hexadecimal digit.

    {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}

hard coding a GUID into the instructions might be an idea, eg

C:\Windows\system32>bcdedit -create
{01234567-0123-0123-0123-123456789abc} -application osloader /d
"WinPE"
The entry {01234567-0123-0123-0123-123456789abc} was successfully created.
