Acer laptop Caldera DR-DOS 7 05 with windows 7

[PaganWoman727]

I'm having trouble getting past the black screen reading A:\> with a flashing cursor at the end. Every time I enter something I get command or filename not recognized. All I want is to get past this and into my Acer laptop again. HELP!!

After the "A:\>" type "dir" then enter. See what in the list. remove the media(disk, cd, usb) and reboot.
