Now my problem is that i have made the setup and it is made like

setup-1a.bin , setup-1b.bin , setup-1c.bin and setup-2a.

When i put the setup-1a.bin to setup-1c in DVD1 and in DVD 2 setup-2a.bin it asks for DVD2 (Please insert the disk 2) then i insert DVD 2 i.e setup-2a.bin . And when i put setup-1c and setup-2a in DVD 2 it asks for disk 1. Please I want to change the Insert disk 1 text to insert disk 2. Because I want to put the files like this.

DVD 1
setup-1a.bin 1.5gb
setup-1b.bin 1.5gb

DVD 2

setup-1c.bin 1.5gb
setup-2a.bin 1.5gb
