I just installed Windows Server 2008. I also installed the Subsystem for unix-based applications. My question is this... can I load ubuntu operating system with the Subsystem for unix-based applications add-on? I was us VMWare to achieve this. Thanks Bill

No. The subsystem for unix is not a virtualization engine that enables running another operating system. It is a subsystem that allows you to run unix utilities and a unix shell. http://technet2.microsoft.com/WindowsServer/en/library/695ac415-d314-45df-b464-4c80ddc2b3bc1033.mspx?mfr=trueis a link for Windows Server 2003, but it is basically the same thing. tgc

Hello, Yes, I think what Tim said was right on the target. The Utilities and SDK for UNIX-Based Applications you installed on your Windows Server 2008 is an add-on to the Subsystem for UNIX-Based Applications component that shipped in Windows Server 2008. However, you could not load a Linux based OS such as Ubuntu OS by this utility. SUA (Subsystem for UNIX-based Applications) supports case-sensitive file names, job control, compilation tools, and the use of over 300 UNIX commands, utilities, and shell scripts. Because the subsystem installs separately from the Windows kernel, it offers true UNIX functionality without any emulation. I hope this helps. Regards, Neo Zhu-MSFT
