I want to install DOS 7.1 in the machine so that I can use Ghost. The machine doesn't have a floppy drive, so I downloaded the CD boot version of DOS 7.1, burned it to a CD, and then ran the SETUP.BAT file in the DOS71CD.ISO file. The screen flashed and then disappeared, and it wasn't installed when I checked again. Running SETUP.BAT in the fake DOS "Command Prompt" under XP prompts for an error. It also seems that the CD can't boot. Although it has been set to boot from the CD, the XP interface still pops up every time. Please, experts, give me some advice. What's the problem here? How exactly should I install it? Urgent! Urgent! Urgent!
