I'm trying to do a fresh install of DOS 6.22. I had original DOS diskettes (3), but they've gotten so old that they're failing. It's been years since I've used them. I had a COPY of the files saved onto harddisk, and proceeded to COPY them onto 3 NEW diskettes. When I try to do an install from these 3 NEW diskettes, the PC boots from diskette (diskette #1), goes into DOS 6.22 Setup, but then asks to insert setup disk #1.....which is already in the disk drive. Is there something I'm missing on setup diskette #1, or is there a 4th diskette that I need, maybe a boot diskette? Any help is appreciated.
