"The Preboot eXecution Environment (PXE) is an environment to boot computers using a network interface independently of data storage devices (like hard disks) or installed operating systems." Its independently but do I actualy need a hard disk and OS installed on my machine? For example i have one server with VM on it and share it via DHCP. Is there a way to boot it from thin client without hard disk drive? And if the answer is yes, how actualy I can do this. P.S: Thank you for fast answer!

Hello guys. I have this issue from the title of this post. So if someone know a way to boot other PC virtual machine using network boot will be very nice. I spend hours to find a solution, but unfortunately with no success. I try to do it with Vmware Workstation and Vmware Server. Is there any way to do this with no hard disk on PC that you boot from. Thank you all, and I'm sorry if you found my questin for stupid.
