    Which emulator are you using? Or are you using real hardware?

  • Though, I wonder why the 7.1 disks works and the 7.5 didn't? is it an upgrade for System 7?
  • It is possible that this specific disk set was not intended for all Macintosh machines. Apple was funny that way.

    The 7.5 disk 1 will boot on a Mini vMac configured for a Mac II. But it doesn't seem to like Mini vMac configured for Mac Plus.
  • Also, one thing I noticed is on Mini vMac are that the 7.5.3 and 7.5.5 disks asks for the disks and the Hard Disk. (Or 2 Disks at the same time) then the emulator crashes and the disk gets corrupt. any fix?
  • Mac OS 7.5.5 works fine on mini vmac (mac plus). You may want to install Mac OS 7.1, then upgrade to 7.5 -> 7.5.3 -> 7.5.5
