If you mean the screen above, that is the loading screen I've been writing about in viewtopic.php?f=6&t=94381#p455695

TheawesomeMCB,
I asked for a screenshot. I still don't have a clue what you're talking about, nothing similar comes up on my VMs... Use the HostKey+E to grab a screenshot.
If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.

I'm not sure what else to screenshot, let me tell you the steps, 1.Go on a windows VM, 2. Restore a snapshot for the windows VM 3.Restart the VM computer 4. The screenshot fth0 has provided. 5. The VM crashes.

Something has gone wrong in your snapshot arrangement for your guest, and the error is influencing the guest OS such that it crashes then reverts to the low-resolution startup green bar screen. This is not a different OS, as fth0 points out, but is a low-res fallback for the OS boot process.

You should either consider restoring a backup of this guest if you have one, and you should have one, BTW, or reinstalling the guest OS. Snapshots do make the guest more delicate, but they can be usable, and aren't prone to the error you are getting. I suspect something bad in the snapshot disk file itself.

I would also not use snapshots myself except for experimenting, and keep a complete undamaged backup on guests I plan to experiment with. A simple copy of the guest folder (provided the guest disk is also in the guest folder) is a good backup. As long as you need to just revert the guest back to the backed-up state, just copying the guest disk file from the backup back over the corrupted disk file would be a valid restore. This is a different arrangement than you have now, though, and you would need a fresh install with no snapshots.

I wonder where these vms came from? Multiboot vms are pretty unusual. Unlike physical machines, there is really no reason to use multiboot in a vm. It is simpler to just create a separate vm.

Why do you think a multiboot VM is involved? :?

I see your point. The "other OS" was a red herring. I also see why you want the heading changed.
