El Torito Image - part 2

Today I can give you guys more info about my problem.
This morning, after etprep the HD was still able to boot, but only if the pre-fba CDRom was inside.
Removing the CD the system could not be able to start anymore (BSOD).
I tought it was a letter problem, in fact "SET" command at the prompt showed many environment variables (i.e. "ProgramFiles") with the "C:\" prefix, not the "E:\".
I went into registry and manually modified the strings containing "C:\..." into "E:\..." and committed my changes to the HD, except for those in HKCM\System\MountedDevices (affected by etprep I suppose).
Now the HD was able to boot alone, with system root "E:\"!
I was full of hope! I burned the image of the HD (I created new SDI disk, copied all the files, made hd2iso on SDI disk, then burned the ISO).
Still 0x0000007b.
Am I going in the wrong direction? Is in this discussion group a solution that I've missed?
 
Try removing HDD from your device.

It is very hard to diagnose why it is not working, if you can and know how
try using kernel debugger.

There are too many things that can go wrong with El-torito if you don't know
exactly what you are doing.
Also You should use google groups to search for previous EL-torito questions
and answers.

I think that I know everything MS wanted me to know.
Previous solutions found in this newsgroup don't apply to my situation
Anyway, I have to thank you for your reply
I had already tried to disconnect my HD, plus changing BIOS parameters related to IDE controller.
Nothing. I'm going on
One more question
- I think that "PnP (User-mode)" is a necessary component for the success of El-Torito CD preparation. Am I wrong

Thank you again

Hi Michele,

You probably do know everything that MS wanted you to know, but sometimes
that is not enough.
- For instance you can use my solution for configuring REG RAM EWF without
extra partition.
- Also you can change start parameter for two drivers required for el-torito
boot during the FBA.
- You can also modify manually volume names in registry.
- You don't need to use etprep, everything can be done manually.
- You can use second partition as C: instead of first.
- workaround for hd2iso problems.
- etc.

You got my point, you can make your procedures and checks for every step.

of El-Torito CD preparation. Am I wrong?

You should have all components related to PnP. (It is always good to have
them).

One thing:
Check if both your devices are exactly the same:
For instance position of CD-drive on cable. (Master/Slave Primary/Secondary)
