BootDisk.com

As a Mac user, I have long been familiar with disk images. I really didn’t know that the Windows world had them. Although I really don’t think they work completely the same as they do on the Mac.

BootDisk.com has disk images of Windows and DOS Boot Disks as well as images of a lot of the utilities.

For example one page has the following list:
WINDOWS AND DOS BOOT DISKS

DOS/Windows9X/Me/NT/2K/XP Excellent Bootdisks
