A friend of mine gave me a pc that was not working. All I had to do was replace the memory chip. Now I have a working Windows 7 and it's only a year old. I am now trying to get VMWare Workstation 8 up and running. Everytime I try running the virtual machine, the screen turns black as in DOS mode with this message: PXE-E53: No boot filename recieved. PXE-M0F: Exiting Intel PXE ROM. Operating system not found. I just downloaded the VMWare workstation program. Do I need something else to get this to work? I will be thankful for any help.
