Urbackup image restore windows 11 errors

Has anyone been able to do an image restore with a windows 11 image? I’m trying to restore it from a dell PC to a virtualbox VM. urbackup restore works fine without error but the resulting VM won’t boot. I’ve tried various commands to fix bootloader error and event boot-repair 64 but it won’t get past the boot loader.

When I boot into a recovery console the C drive looks to have the right data and such but the host will not boot.

Any ideas or steps that folks have tried to get the image to boot?

I have not had any problems restoring to windows 11 pro to a physical disk. What urbackup server and client version are you on? I suspect it is a bootloader fix and also a tweak to a virtualbox VM setting. Do you have a windows 11 vm that you installed from ISO that is booting and can you compare the virtualbox settings to that of the restored VM and see if anything is different. Also are you going from a physical windows 11 backup into a vm restore or is the original backup also of a VM or a physical disk?

I went from a physical to phyiscal as part of an SSD swap and that didn’t work on the same machine.
So I did a fresh install of W11 on the physical with new drive and it was fine.

I then tried to restore that old image to a VM so I could get some chrome settings exported from it. The Virtual box VM is setup run a windows 11 host and work ok.

I used the following

URbackup 2.5.36

windows client 2.5.28

urrestore ISO 2.6 took all defaults during restore

I double checked all the settings and they seem ok. The wierd thing is when I boot with a windows CD into a recovery doc prompt I can go to the C drive and all looks ok. I only checked a couple user files on knew were on the desktop, but the data looked ok on the restored host it just won’t boot.

Are you getting a specific windows or virtualbox error when the restored VM boots or just black screen or ?

Current Windows Client version is 2.5.29

Previous had a few issues fixed …

No error from virtualbox. Windows goes to what I assume is the start of boot loader, the screnn with the dell logo and a pinwheel spinning. Then it should go over to the first MS screen which also has a pinwheel, but instead pops up a screen saying there was an issue. Then it tries to restart and repair itself but can’t and gives a text file. I’ll re-restore and get the file I didn’t see anything good in there. I’m not as familiar in how to get a more verbose log of the boot process from BIOS or windows.

My guess the host machine was installed with a specific HDD controller/raid controller and the VM use its own controller. So the restored OS is missing the HDD controller.

Should be an option to not reboot after blue screen. Turn that on, what stop error are you getting?

Do you have access to the original machine? Check your bios, was it in IDE,AHCI or raid mode? you may need to match that with the VM your trying to run.

Also, may need to boot off a Virtual ISO windows install disk, and side load the correct HDD controller drivers into it.

Ok thanks, i’ll give that a try.

I’ve attached a set of screenshots of what i’m seeing

  1. Retore do HDD goes ok

  2. First boot windows bootloader shows error it tries to restart itself

  3. It tries to diagnose and fix the system on it’s own but can’t and shows the second screen

I can then boot into windows recover console and launch a dos prompt.

When i do this and type c: i can see the c drive just fine.

I’ll try installing windows 11 on a VM and just replacing the main system partition on the VM. Thanks

I tried the fresh install of windows 11 which booted ok and just restored the C partition to the c partition on the VM that was working and same thing. it boots into an error saying there was problem, then it’ tries to diagnose and fix it but can’t

I can boot into a recovery console and see the C drive with a dos prompt but it wont’ boot.

is the original system still bootable ?

Open up device manager, and expand “Storage controllers”
what devices do we see there ?
