Restore to virtual machine fails: the boot selection failed because a required device is inaccessible

Post by daystrom » Nov 10, 2019 4:13 pm

I am trying to restore a veeam agent backed up windows 7 virtual machine, something I've never tried before. What I did was:
- volume back up of system, C and D to a spare partition on the virtual hdd
- restored system, C and D to a new virtual hdd
- removed the original .vhd that the machine has been booting from
- windows boot fails with "the boot selection failed because a required device is inaccessible"

That error screen suggests booting to windows install disk and doing a repair. I attached a windows 7 pro iso, and booted to it. It asks me to select the OS to boot to, windows 7 is the only entry in the list, and then I get the "the boot selection failed because a required device is inaccessible" error again.

What have I missed in this process?

This took care of itself. I restarted the host; tried the vm again, and this time it didn't ask what OS I wanted to boot to. It showed the "install windows" screen, with the option to repair, and the repair worked.

Hello daystrom,

Thank you for your post and glad to hear that you've found the solution. Based on your description it looks like an issue with the VM you've used to restore backup to. I'd recommend to use newly created blank vm as a target whenever you need to perform a Bare Metal Restore to a VM (that just helps to avoid possible conflicts with the existing VM configuration). Cheers!
