Hi Paolo,
It looks that you have problem with disk.sys driver that is much on lover level in drivers chain that volume letter assignment.
Since if you don't have disk driver then partitions and volumes are never exposed.
Quick try would be to use HDD that is different from HDD that you used during the FBA. Also you can try with HDD that you used
during the FBA, just to compare results.
Before creating SDI file, please delete setupapi.log. (Optionally in registry increase log detailed shown by setupapi)
When you boot from SDI file your setupapi.log will contain only information's related to why your disk failed to start. Please send
this file in this NG.
This also could be PnP related problem (Please check that you have User Mode PnP component)
Regards,
Slobodan
