OS 4 Classic - Fresh start, dual boot?...

[TiredOLife]

I have two 1 gig partitions for 3.9 and 4.0.
OS4 is my default partition.
Just use the boot options in the early startup menu to boot to 3.9.

Don't forget if your 3.0 and above reboots because of blizkick for instance, you will need to use the early startup a second time.

Yes, both bootable.
I'm using SFS, which both 3.9 and 4.0 are happy with.
I put the two partitons in the 1st two gig as I had problems when using the 1st 4 gig although that should have been possible.

Probably easier to start of with OS4 1st, as you can boot from the floppy provided and the installation goes ahead quite easily.
The tools for partitoning and formatting are all there.

No problem
