I'm using VMware Workstation 7.x on Windows and I'm getting this error when I start my VM:



error loading operating system


That started to happen when I tried to load the VMDK file into the program VirtualBox. Prior to this, it ran just fine. Ever since then I have been unable to start it in VMware Workstation 7.x



I've already tried to repair the VMDK file but when I do it tells me there are "no errors found". I used



vmware-vdiskmanager.exe -R "c:blahmy vm disk.vmdk"


Anyone else have any more suggestions I could try? It's a 300+ GB VM and I don't want to lose it.

          Did you use the VMWare converter? If so it should give you two options:




          1. Choose the volume and then create the vmdk

          2. Maintain the Disk Size.


          I believe you want the second options.

          • But i already made the VM and just decided to try and see if it would work in VirtualBox. It only messed up because i try to start the VM in VirtualBox and VirtualBox did something to the vmdk file i guess?

          Most likely, you'll be able to get it running again with a Windows Rescue disk.
