I have a PowerBook 145B but something is wrong with the systemfolder so it wont boot. I've downloaded System 7.0.1 from Apple and put it on Floppys with my Macintosh Classic. The PowerBook boots from the floppy but after a minute it just comes up a window thats completely white.
I've tried a lot of things, but my Macintosh classic (with original floppys) runs 7.0.0. And the PowerBook needs atleast 7.0.1 and did run 7.1.0 as original OS.
How do I fix this?
You may want to try another startup floppy for a test. Use, for example, the Network Access Disk 7.5.
Make sure that you are using Disk Copy (the Make A Copy button in version 4.2, or the Make a Floppy command in 6.3.3) in order to create a correctly sector-copied disk from the downloaded image.
