I wanted to know if there is a way to use OSD without pre-staging a computer association in SCCM, since i'm having trouble creating them http://social.technet.microsoft.com/Forums/en-au/configmgrosd/thread/d73011b9-43c0-43a2-93dd-b006900ca300 i wanted to know if there is another way?? Running SCCM 2007 R2 on Win Svr 2008 R2 thank you!

If you have R2, why not use Unknown computer support ? http://technet.microsoft.com/en-us/library/cc431374.aspx

As above, unknown computer support is your best bet, or alternatively you could create some offline media to a USB or something and build from that.
