The M$ OPK winpe.chm(Sep.2006) says it can, in "Customizing WinPE"->"WinPE walkthroughs"->"walk through: boot PE from hard disk".

but I failed, following its instructions. and especially,

bcdedit reports error message: cannot open system store,

and I use bcdedit /store to explicitly specify it to work around, but

when finished, it still cannot boot, report some errors like "C000000F, winload.exe missing or corrupt".

any ideas? thanks in advance.

copy all the files in the System32\Boot folder to the root of System32. This is a known bug that was reported to Microsoft, and was supposed to be fixed for the RTM release, but wasn't.

EDIT:

I use this command in my build script

xcopy "%source%\mount\Windows\System32\Boot\*.*" %source%\mount\Windows\System32\*.* /e /y

This should fix your winload.exe error
