[IAEP] Trouble With Helper CD

[laura at penobscotschool.org]

I am running a Mac Book with OS 10.5.6. I tried using the Helper CD  
and SoaS stick distributed at the FOSSed conference. Following the  
wiki directions, the Helper CD booted up then required a decision  
about booting options. After choosing the "boot" my machine locked up.

When I restarted my machine, it did not recognize my boot drive. I can  
no longer get into OS X. Before I reimage my machine any suggestions?
