Hello members,
How to launch windows program in DOS at OS selection screen during boot?
To share the concern better, I have made a video taken from someone's computer and wish to setup same at mine. Kindly have a look at the following link:

I'm a little unclear at your goal here, even after viewing the video. The OS Selection menu is meant to show which operating systems you have available in a multi-boot system. Are you trying to launch another operating system or have an application start with your current operating system?
