SBS 2008 – Restore Failed – Element not found 0x80070490

We have been spending some serious time tearing into SBS 2008 by breaking all sorts of things to see what happens and to figure out how to fix them.

In some cases, we are successful in getting the fix in, and in others we are still on the short end of the learning curve.

The big confidence builder in all of this is the fact that the built-in SBS backup is phenomenal! The ability to restore various aspects of the server up to and including the server itself is simply the best out of the box backup system we have worked with on any Microsoft OS product.

We have restored the bench SBS 2008 box so many times from so many backups we made during our testing that the built-in SBS backup is a viable contender to stay on the box as the de facto backup solution for SBS 2008.

The one spot we have not tested yet is the built-in backup’s ability to restore to different hardware. Though, from what we can see, the ability is there as the restore process gives us the ability to install drivers prior to running the restore.

While working on one of the restores, we ended up receiving this error:

09-03-05 SBS 2008 Recovery Fail - 0x80070490

Windows Complete PC Restore

The Windows Complete PC Restore Operation failed.

Error details: Element not found. (0x80070490)

It did not take much to find the reason behind the error: WindowsNetworking.com: Performing a Recovery Using Complete PC Restore.

It seems that even though have the USB Boot Priority disabled in the BIOS, the boot order was set as follows:

09-03-06 SBS 2008 - Backup - BIOS Settings

USB HDD Set as Default

The recommended action in the WindowsNetworking article was to keep the USB HDD unplugged until it came time to scan the backup drive for the backup being used to restore the system.

Once we left the USB drive unplugged during the POST and subsequent SBS DVD boot, we were able to accomplish a successful restore.

Hi,

I was getting this exact error trying to restore a backup off the network, Web server 2008. I turned off booting off usb and network. But I still get the same error. Very frustrating because this error is not very helpful.
If I had any hair, I would be pulling it out.
Thank you for your post it gave me a ray of hope. Microsoft does some things very good and some things very bad. Very poor error information and I cannot find any information on this error.

Thanks,
Victor

Follow up because you were only one posting about this error.

I was trying to restore a backup of Windows Web Server 2008 that was installed on a Citrix XenServer. Wierd configuration, drive 0 24G as D:, drive 1 100G as c:. Backed up full system and then tried restore to bare drive, and then partitioned drive. Error - The complete PC Restore failed. Element not found 0x80070490. I added second drive to sata1 and this did not work.
So set sata0 to 80G drive and sata1 to 250G drive.
I then went back into recover and on the last step I went into advanced and unchecked reboot when done and the unchecked the check disk option.
I do not know if unchecking the two options or arranging the drives to match the virtual drives worked but the system restored.

If I run more tests I will post.
I wish MS would supply more information than the poor error message. Especially with something as critical as restoring backup.

Thanks,
Victor

Why does Microsoft not just put in proper error messages, like remove the dam drive before you boot. It would make life so much easier!!!!

Thanks a lot for this tip. I was getting the same error trying to restore a backup from usb-hdd to my hp dl 380G6 with W2008SRV. I try something different ways, but always the same error occurs. Then I went back into recover and on the last step I went into advanced and unchecked reboot when done and the unchecked the check disk option. The system were restored.
Thanks and Greetings

This is a great guide, I had the same problems as you had.

My setup was a little different though. I had to restore a complete server over remote KVM. A USB disk was attached to the computing module with the backup image on it. So I couldn't just unplug the USB disk when I got the element not found error...

I decided to have a look at the BIOS myself.
I changed the USB boot priority to disabled. I also changed the hard disk order. Because if the USB disk was attached at a previous boot, it would be on top of the list already. (Philip, I thing that is why you still could not restore after the change)
After these changes. The restore did start for me.

I'm off to sleep now, hoping by morning I will have a bootable system...
Thank you for the article.

THANK YOU SO MUCH!!!

If I was young and cute I'd kiss you!!

A quantum leap in in help for 'microsofted' people !! Thanks a lot.
In my case, it helped already changing the boot order of hdds in BIOS once (target drive first, source drive second).
After that, everything worked perfect as -it should.

You are THE MAN. You saved me spending hours and days to resolve this.

I was replacing a SBS 2008 installation on a HP Proliant ML110 using P212 Smart Array. Was wondering why was it failing when all seems in place. your article is a God send.

Thanks you my friend :)

Thanks a lot! It is working :) I made restore SBS2008 with raid 1. Before I changed the HDDs with largest capacity. I thought it a problem but my think was wrong.
Thank you again.

Thank you so much! Luckily, your solution was first on the list when I did a search on the error. I have already wasted enough time with this raid controller. I am tired and want to go home. Thanks again.

Thanks! Same error here.
I was actually booting from an ISO on a USB thumb drive. Tried lots of different things booting from USB, but nothing worked. Once I read your post, plugged in a DVD drive and booted from an actual DVD (with no USB plugged in), it worked.

Hope works for me....

Thank you very much! I was starting to panic when I wasn't able to get a restore going after a failed disk repartition attempt.

Unplugging the USB hard drive initially did the trick for me.

Thanks again.
