Windows Inaccessible boot device help please

Thread needs solution

My setup.

Current home PC Asus motherboard with RAID enabled. Windows OS disk single SSD not RAID (data disks are on RAID). Migrating to new build PC, Asus motherboard RAID enabled,  Two NVME drives on RAID for OS, Two spinning disks on RAID for data. One drive not on RAID for scratch disk.

Preparation.

Installed latest Intel Rapid Storage Technology Driver on current PC so up to date.

Used Acronis Cyber Protect Home Office to backup complete OS disk to USB drive.

Used Acronis Rescue Media Builder to restore backup using mirrored NVMe drive on new PC

Used Acronis Universal Restore to inject Intel Rapid Storage driver.

Problem

Boot PC,  get inaccessible boot device error, goes into preparing automatic repair which failed. Go to recovery window select keyboard > trouble shoot > command prompt. At command prompt typed diskpart, list disks. No disks found, so not seeing disks on RAID nor the disk not on RAID.

I can install a new version of Windows on the NVMe RAID drive so the hardware is working OK,  stuck with how to fix the restore on the RAID drive so any help appreciated.

Hi many thanks for the help.

I have pretty much tried those options I used Acronis Universal Restore to add the Intel RAID driver after the restore, but it did not help. I am unclear what to restore although I have tried the following

1) Complete original disk restore to new disk. This will copy across the Track 0 I assume this is a bad idea for a new system?

2) Installed fresh copy of Windows to create EIF partition and Restore partition, and then just restored the C: partition backup to the new Windows partition

Done both methods with and without using Acronis Universal Restore to add the Intel RAID driver. All fail with the same inacessible boot drive error message.

Is it possible to move from a system OS disk on a single drive to a new system with a larger RAID drive? Both PCs are UEFI based so that should make a little easier.

Please confirm that the recovery media (being used for the restoring to the new PC) is being created on the new PC. If not, the correct RAID drivers may not be loaded. When creating this recovery media, include Universal Restore (but it may not be needed - just abundant caution).

Please confirm that the new PC uses Intel Rapid Storage Technology rather than the newer VMD controller. In the latter case it can be challenging to restore to a PC that uses it. Assuming it is a relatively new system it will use a VMD controller.

As Ian points out you have likely run into your backup not containing the Intel RST VMD storage driver.  You should be able to download this driver from ASUS support site.  Once downloaded unzip the file to its own folder.

Next create new rescue media and point to the iastorvd.sys driver found in the folder you have created.  You must use the advanced option to add drivers when creating rescue media to get the option to add drivers.

Hi Ian, yes the new motherboard has the Z790 chipset with VMD controller. From what I can see the VMD driver is always used even if no RAID. 

I managed to restore to a non RAID drive OK, then used IRST app to extend the drive to a mirrored RAID setup. 

David,

What driver is your mirrored RAID setup using?
