Image x and no bootable devices found

Hello,
I recently created a Vista image using ImageX. I foillowed the step by step
instructions, and sucessfully ceated the WinPE Boot disk and a Vista image. I
used the following commands:

1.) created Sysprep.html using the Windows SIM
2.) sysprep /generalize /shutdown /unattend:sysprep.html
3.) booted with WinPE disk
4.) imagex /capture /compress fast /verify
5.)_applied the image just created back on the the source pc.

I get the message that the image was successfully applied, exit from WinPE
and reboot. On startup, I get the message that no bootable devices were
found, or that Windows failed to start because of a recent hardware or
software chang.

I think I'm close to getting this to work. Am I missing a step, or some
switch in the command line? Re-applying the image to the pc it was created on
shloud not cause any problems.
