If you don't have system software already on the hard disk with the PC Exchange control panel installed, the machine will be unable to work with PC DOS formatted diskettes. PC Exchange should be included in a standard System 7 installation, however it will have to come from Mac formatted (HFS) diskettes.

The other mac will need to be capable of writing to HMS format. From there you can copy a system folder to the diskette.

Ok cool . I just used a powerbook 145 to transfer the system file and the system folder and it transferred but the disk just ejects when i try booting from the 100. The system file says it is currupted or something

I would have guessed that this meant that you needed a different System Enabler, but the PB100 doesn't actually need one apparently, so I'm not sure what's going on...

It occurred to me, if the System Folder you copied to the diskette was an installation specific to the PB145 in some way and not a generic installation of System 7, that may be the cause of your problem. Try copying a generic System 7 Installer to the floppy and installing that way to the PB100 and see what happens (you'll need to boot from a copy of Disk Tools first).

You might also try with a copy of System 6 (6.0.8L to be specific) as that's the original and earliest system software that came with the PB100. If you're able to get that working, at least you'll have a system on there, and then you can upgrade to 7 at your leisure.

Wouldn´t it be more straight forward to prepare a set of installer floppies from pristine disk images with DiskCopy?
DiskCopy is not installed by default with MacOS - always wondered why - but we have a page for it.
Of course DiskDup+ can create floppies from disk images just as good, its a matter of taste only.

Depending on the amount of RAM it may be wise to stick with System 6 under low RAM conditions.
Otherwise System 7.5 might be my choice for a PB100.
7.5 has roughly the same RAM footprint as 7.1 on 68k Macs.

Floppy images are on the Apple Legacy Recovery.iso.

All is good advice. I agree i think becuase i used powerbook 145b backup application thats why it wont work. I guess i have to buy floppies now for system 6. Thanks

No need for that; if you're able to put a copy of System 6 (which you can download on the Garden) onto your PB145, you should be able to then copy that to the floppy disk you already have for use with your PB100.
