I use Ultrabac software for back up and restore, and bare metal restores. It works very well. I highly recommend it. Recently, I found a problem with restoring Win 7 64 bit machines to hardware with a two drive, RAID 1 array. This has never been a problem with Windows 10 64 bit Pro restores, regardless of the target hardware. The current target is an HP Z 420. I can put any Win 10 on there from any source without issues.

The main problem is once the Win 7 image is restored to different hardware, upon first boot, the Intel RAID 1 Volume IS there, the machine boots normally and starts installing all the drivers as expected. It also creates a RAID device that is missing a driver listed with other uninstalled devices. If I leave that RAID device as is, BSOD on reboot. If I uninstall it, I can reboot without incident, and this mystery RAID device comes back as it was before, seeking a driver. This does this against any and all Win 7 images NOT generated on the same kind of hardware profile.

The RAID device does NOT have a disable option in the contextual menu, just Update driver or Uninstall. I tried to install the RAID driver used in the boot disk that is used to run the restore jobs, Intel Rapid Storage RAID driver. Restore disks are built machine specific with RAID and Ethernet drivers injected into the restore disks as needed. When I try to install those drivers against that RAID device, it takes the drivers, then fails with an error "Cannot create a stable subkey under a volatile parent key." At that point, the RAID device becomes an unknown device, and at reboot, BSOD that I can't recover from.

The vendor has only seen this once before, and thinks there is a registry setting that causes the creation of this, what appears to be, an "extra" RAID device. Everywhere else one can check, the RAID is installed and working as single disk. The RAID works. If it didn't work, I would not get a boot cycle at all. This needs to be addressed via a registry setting, but we aren't sure how or where to address this "ghost" RAID driver that won't install, nor will go away.

Any ideas? Thank you.
