sorry for the long delay, but here is the final word on this thread.

Never could solve the problem.  I did a clean install and all is well for one month now...

I did earlier (i.e. yesterday), but I had read at the time that the osX partition (i.e. HFS, my partition #2) should be the active one.

In any case, I just tried setting chameleon (EFI, partition #1) as active using fdisk.

Didn't work; still showing boot0: error

I tried it again just to be sure, and, yes, I got an output just like you described.

still getting boot0: error

By the way, I have been looking at my hfs volume with diskutil and in Ubuntu with gparted.  It is really messed up!  I can't mount the partition, i can't repair the partition (either in OsX disk utilities or with hfsprogs in Ubuntu).

I have found several references to running pdisk to try to let the computer know how big the partition is and so on...

e.g. http://www.nathanhei.../tag/partition/

...which might allow the partition to mount, but I can't figure out how to load and run pdisk on Ubuntu.  When I try it in OsX terminal, it won't work (presumably because i am booting into the Os X install disk, and I can't set superuser permissions that way, sudo doesn't work etc.)

So I am at a complete and utter loss.

it seems like it did (both times), since several lines of code followed that said something like 1 of 1 file copied.  Is there any way I can tell for sure that it copied?

OK, I found the boot1h file

But where exactly do I put it?

Should I be doing this in Linux or after booting into the SL install disk and then opening terminal?

I followed the instructions and copied the boot1h file to /dev/disk0s2

(which is my HFS Os X partition)

it seemed to copy successfully.

I restarted-- same boot0 error
