Windows Guest Crashed and now won't start

[RossW]

My Windows 10 guest seemed to freeze while I was updating my DropBox sync settings so I left it running to sort itself out, but when I checked later it apparently crashed (strangely, the MacBook said the external thumb drive was not ejected properly, but it was still plugged in). In any event, I now cannot start my VM:

Code: Select all

I do not have a backup - is there anyway I can recover this? I saw cloneVDI mentioned in other threads but don't think I can use that on a Mac.

This is more a "me too". I too have a need that I think I thin cloneVDI could help. in my case I am sealing with a Linux Guest riding on a Mac Host

[RossW]

I’m stuck, I think, as CloneVDI only runs on Windows and my other Win10 VM does not have enough free space to copy over my affected .vdi.

thanks for the info. I need up deleting and starting. over there goes another day
