hi friends
i have encountered an strange problem.
in my servers with windows server 2008 R2 full installation (not server core) & also win 2012 R2 full installation, when in my virtual machines (VM OS = win 2008 R2) , in disk management snap-in i convert basic to dynamic, system normally boots after restarts & no problem occurs.
but i have another server on which i have installed "windows hyper-v server 2012 R2" which is core edition. on it i also have virtual machines. in these VMs when i convert their disk from basic to dynamic, then after restart system remains in the black screen & never boots.
any help please
thanks in advanced
