Restore from SDR on a remote server won't work

Hello,

I come here again, because I'm proceeding my bunch of tests. Currently, I try to restore my main domain controller (Active Directory + DHCP + DNS) on a remote server.

The two servers are from Dell brand, physical.

The disk configuration "appear" to be the same (not the case apparently), but the system reserved and OEM partitions are recognized as incompatible, the size is ok.

Image may be NSFW.
Clik here to view.

*For the OEM, I've created a RAW partition instead of NTFS

• The system reserved partition is recognized as System, but not Active, when I boot on the SDR disk
• The OEM Dell Partition can't be manually created I think, I just need to the right file format I guess.

But my question, is why the System Reserved 100 Mb partition is not compatible ? I mean, it's the same both side !

Thanks in advance,

Regards,

Alex
