was running diskwarrior on my 2007 imac running 10.6? as i always do every so often. when i was done i couldn't find the option to choose the startup disk so i could restart from the computer's drive. keeps restarting from diskwarrior. resorted restarting w/pram procedure in hopes of tricking it. nope. then tried restarting holding down shift/eject. nope. i'm not a whiz when it comes to this stuff some i'm prepared to physically fish the disk out unless someone here knows of any tricks. fwiw, i've run the my current version of DW many times on my current OS version. can't understand why all of a sudden it is doing this.
