Answers: What OS test menu?
If you're conversation in the region of the different starting modes in Windows, I don't ponder there's much you can do there.
If you're conversation give or take a few a bootloader similar to Grub, later you'd stifle the configuration record and steal out the entry you don't want.
Go to start>run type contained by "msconfig" and hit enter. Go to the "Boot.ini" tab, and look for the [operating systems] header.if at hand is more than one entry below that heading, remove the one you don't want. Be sure you delete the right one, otherwise you will not be capable of boot posterior into window.
