Debugging NTLDR

NTDEV
1

I am attempting to use WinDBG to debug a boot driver and would like to
use its ability to map drivers at boot time. The help fies say the way
to do this is replace the standard NTLDR with the debug version from
WINDDK/debug. I have tried the NTLDR_dbg from both the 3790 and 5112
versions of the DDK and both of them give me a “NTLDR corrupted” error
on boot. It seems like I am missing something very basic, but can’t
figure out what. Anyone know how to solve this?

Thanks,
Matt Monroe

Does your target use EFI hardware? If so you can’t.

My target is running in VMWare and connecting through a virtual serial
port. Are there known problems with this?

I’m assuming your trying to use the checked version… If so, you did
decompress it with the expand utility right?
