Parameter

Description

timeout

The number of seconds the user has to select an operating system from the boot loader screen before NTLDR loads the default operating system.
If the value is 0, NTLDR immediately starts the default operating system without displaying the boot loader screen.
You can also set this value to -1, in which case NTLDR waits forever for you to make a selection. You must edit the Boot.ini file to set the value to -1, because it is an illegal value for the System option in Control Panel.

default

The path to the default operating system.
