Hi,
I work for a small company and we are running off a single DC with windows server 2008 R2 Enterprise installed, it has a single drive that is mirrored using windows software. I have a full image backup that is backed up to a dedicated removable hard drive. I have been trying to test the restore process on a machine with different hardware to the source DC. Which i need to do incase of a worst case scenario eg, the server is stolen/damaged beyond repair.
My problem is when i try to restore in win RE i get 0x80042412 error saying the destintion drive is not suitable. The destination drive is about 100 GB larger than the source drive. I have tried using wbadmin with sysrecovery and i get the same error. I then tried to use wbadmin start recovery and got the volume to restore, but the machine wont boot, and get a BOOTMGR is missing. I then ran the recovery utilites i read about in other forums. i.e. bootrec.exe /fixboot and /fixmbr. I have tried deleting c:\boot\bcd and using bootrec to rebuild the bcd. i have run bootsect /nt60 c: /force and lastly i have run the StartRec.exe in the recovery dir on the WIN RE.
I have also tried a clean install and the booted into directory service repair mode and tried restoring just the system state. My best result so far is getting the server to boot to the loading screen and then the machine crashes and reboots.
I have not seen any other suggestion i haven't tried already. and help would be greatly appreciated.
Best regards

Hi, you need to first configure the disks on the destination machine the same as the source, run Diskpart on the source and then list disk
This will tell you how much space is needed on the destination.

Thanks for the response, unfortunetly that did not help, the source has the usual system reserved partition of 100 MB with an offset of 1024 KB and the primary is 297 GB with an offset of 101 MB. I did a wbadmin get items -version:<version id> and see the main partition is 297.99 GB so what i tried was install a clean installation, then booted off the cd and with the command prompt and diskpart formated the 100 MB and deleted the main partition and then recredted the main partition with a size of 298 GB
The offsets for both partitions are the same as the source. the only difference is there is a very small partition that is labeled as dynamic disk that is the only thing that is different. I read from one of the posts supplied by Tim that the backup should work irrespective of the raid configuration on the source server.
Any other suggestions i have not thought of?

Also are you configuring the raid the same on the dr box?

No it has only a single drive. Its larger than the source drive. But is not part of a raid. I have thought about that and its the last thing i havent tested but i dont have 2 drives of equal size to test so thats why i haven't tried. do you think i need to set up the same raid on the destination machine?

i finally have an update on this, i discovered that the drives on the source were bigger than i thought, anyway i managed to get the image to restore through the wizard on a hyper-v machine. it complete with no problems being reported, but the machine wont boot. I get to the loading screen and the machine crashes. I also have noticed that the c:/boot folder is missing. and suggestions would be greatly appreciated.

So no one has any information on this? I have done all the repair options:
bootsect /nt60 all /force
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
nothing seems to get the machine to boot.

Hello,
You have mentioned that the OS disk is mirrored using Windows software. Were there two disks during backup ? If there were then you should attach two disks during recovery.
You should make sure that for restore to succeed - the number of disks and their size should be equal or more than backup time specially for the OS disks. Even if a single byte is less the restore will not happen.
To know, which disk will be used to recover your OS. Boot from Setup DVD, Cmd prompt, Diskpart.exe, Select Disk=System. This disk size should be greater than backup time boot disk.
More info:
