Hyper-V VMs take up a lot of diskspace. Your lab VM has a temporary storage drive which gets wipped after every reboot. To save space on your C:\ I’ve told Hyper-V to store sate files on this Temporary Storage partition and then placed backups on the C:\ partition. If this doesn’t make any sense don’t worry about it, just follow the image below to copy over the files so your VMs will boot.

Use the Hyper-V Manager to start up the lab virtual machines.

Corection! First start Einstein-dc01, wait 20 seconds or so, then start the remaining four VMs.
It’s entirely possible that this issue was isolated to me and me alone but just to be on the safe side. I noticed that the Ubuntu screensaver was causing my RDP session to freeze which resulted in annoying VM reboots. I recommend disabling it just to be on the safe side.
