You shouldn't have a problem with this, just install win95 FIRST, and use a DOS boot floppy to install booteasy. Win95's boot sector locking will foil attempts to install booteasy under it. > However the first time I did this, I got the > "operating system missing" message when trying to boot FreeBSD or the > old Win slice. Did you run Fdisk and make sure that the active partition is set to the Win95 one on the IDE disk? FreeBSD will reset the active partition bit and if it's on the second disk it won't boot. > I have 2 possiblities for this: > 1) I installed booteasy on the IDE drive via a DOS shell under > Win95.

It won't be able to figure out how to boot it without a clue from the Boot: prompt. > Also, somehow the SCSI disks slice information got written onto the > IDE drive. I think this might have something to do with the shadowing. That shouldn't have happened. Are you sure you installed to the right disk?
