Software installation will then begin.
Linux-Mandrake 7.2 is available on multiple CD-ROMs so when you see an alert message to change disks, insert the requested CD into the drive or just press "Cancel" if you don't have it.
And don't worry if you don't have any additional CDs -- all the essential packages are located on the Installation disk. Certain retail packages bundle extra CDs in the boxed sets and the "Extensions" CD is the second disk of the GPL version.
