VM stuck at GRUB command line on boot

[FallingSloth 2]

I have a ubuntu server vm that is stuck at the grub command line on boot.  From there I can see both partitions and view a list of folders on each partition.  I mounted the vdisk into a desktop ubuntu vm and it shows up as a blank disk (all unallocated space).  How can this be fixed, at least to the point where I can grab a couple of scripts off of the vdisk?

Perhaps install a fresh Ubuntu server on a different vdisk and see if you can mount the broken Ubuntu vdisk as a secondary disk?

I mounted it in a different ubuntu vm as a second disk, it shows up as 100% unallocated.

Make a copy of the image, and use testdisk from https://www.cgsecurity.org/
