I'm trying to make a boot disk with CopyRoms on it so I can get the ROM from my Macintosh Plus. Immediately after making the disk with Disk Copy it boots in the Plus no problem. But as soon as I mount in the finder on OS 9.1 to put the copyroms program on there, the plus refuses to but from it even tho it just booted from the exact same disk no problem. I don't understand why this is happening.
