I recently started playing with Dynamic Memory on our dev hyper-v host. Today I ran into an interesting problem while trying to PXE boot our task sequence boot media. I had set the VM to use Dynamic Memory with a minimum of 326 MB or RAM. When I tried to PXE boot the thing to put an OS on it I got the following error message:
Clicking OK would cause the VM to restart, and I was unable to open the troubleshooting cmd prompt I normally can.
The Fix: Simple. I up the minimum dynamic RAM to 512 on the VM and I am once again able to boot into PE.
Just a gotcha I figured out and thought I would share.
