to do that, from a run command type 'msconfig'
one more way to do it is from 'my computer' properties, in the 'advanced' tab, select [settings] in the 'startup and recovery' section
from there you should be able to click on  'to edit the startup options file manually,...'
if that doesn't work you can enter recovery console from the OS install disk, follow the instructions to get to a prompt and type 'fixmbr' (for fix master boot record)
