I have got all the MS-DOS installation files on hardrive and have printed out packing.lst, I copied all the files onto disk and have labeled them DISK 1 2 and 3 but when I boot from disk 1 it says invalid system disk please insert...etc. what am I doing wrong? Can someone please help? Thanks a lot.

Two things may be wrong 1) Disk One needs to be a bootdisk. Just copying IO.SYS & MSDOS.SYS onto a blank floppy disk will not work with MS-DOS 6.22. Obtain a bootdisk from my site above or from bootdisk.com 2) Disks need the correct disk label. For Disk One it needs to be DISK      1 Thats DISK followed by six blank spaces, then 1 Disks 2 and 3 need the number changing to DISK      2 and DISK      3 of course! Hope this helps. Mick C
