SOS! Extremely urgent! How do I start a USB CD-ROM drive under DOS?
I accidentally deleted the system on my laptop’s hard drive, and I don’t have a backup. My machine is all external, with a USB CD-ROM drive and a floppy drive. I’ve used Super Boot Disk, but it can’t start the USB CD-ROM drive.
What should I do, experts?
