Restart problems installing 10.6

[pluda]

Hello,

 

I'm trying to update my nb100 from 10.5.5 to 10.6, but I always fail when the instalation restarts the computer to continue install.

 

The process is,

 

I've one image of my 10.6 cd in a usb stick, I double click the installer and it works good, until that restart part, where the pc doesn't boot with the usb inserted, So I can't continue to update.

 

When starting the computer I get always the toshiba logo and the option of chosing to press f2 or f12, doesn't matter what I do, the instalation doesn't continue.

 

what should I do?

 

Thanks
