inaccessible boot device after restore to new hardware

Posted on 2008-10-27

We have done a disaster recovery to a new machine. The restore of the data was through without any errors, however, the system state went through in seconds, and we did not see if it completed successfully.
I know windows 2000 is not very happy going to new hardware, but I need to make this work, and have done so in the past.
Windows boots to just before the log on screen, then blue screens with the error  inaccessible boot device.
I guess this is because it has the wrong SCSI drivers. How do I get the new SCSI drivers in to the registry?

Thanks for the help

Without being able to access the boot device, you can't access the registry.  You MIGHT be able to boot to a custom PE (BartPE) and manually edit the registry hive for the system but I would rather search ebay for an identical server for three years before trying to get that to work.  You will need a binary editor to open the C:\Windows\Reg.dat file and then tediously fine the entries you need to update and copy the proper drivers to their location.  The easiest way to figure out what to edit would be to get the install files for the SCSI driver and tear into them to find the reg keys they create and search for their location in the binary editor.  I have done edits like this for small stuff from within Windows and never through a torn up system and they have taken days but it is doable.

I am able to access the disks via the recovery console, so I know the disks are working correctly. I did also restore the whole system to the disks, and the boot does work up to a point.
I have started looking into a BartPE disk, but am hoping there is a better way to do it.

Actually, with re-reading this it is probably not the SCSI drivers.  I would bet that the partitions got pooched on the restore.  It almost sounds as if the system is trying to rescan the drives (like it does right before the login screen) and is maybe seeing two primary partitions or something quirky there.  With your Bart disk or any boot disk for that matter, see if you can go in and reset the partitions and rewrite the MRB record to make sure all that is clean.

Also, if this is one of those systems that has a "Manufacturers" partition, make sure that the partition type is correct. I have ran into issues with Microsoft ADS and Altiris misinterpreting those drive types.

okay, so we have 2 disks in the machine. Both disks have an active partition. the first disk has 2 primary partitions, with the first partition set as active.
The partitions are labelled C,D and E.
Should the C partition be primary and active, the d, secondary, and E primary?

Yes, that should be the correct order.
