Is there any way that I can install BeOS Personal Edition 5 without having Windows?

I'm not sure, but I think you can do it from a DOS boot disk.

Yes, you can install BeOS R5 PE without Windows...
in Linux (for example), just uncompress the .tgz
archive, do something along the lines of "dd if=
floppy.img of=/dev/floppy", and restart.

Or, you could create a bootable BeOS CD from the
two image files & use it to install onto a blank
drive (search on http://www.betips.net for the specifics).

The basic requirements are:
1) a way to download PE archive,
2) a way to uncompress it (it's 0.5 GB), and
3) a way to invoke the bootloader (like a floppy)

As you might imagine, there are a number of ways to
go about this... what are you trying to do,
specifically?

I think should do this:
1)Make a directory called DOS.
2)Copy the content on C:\WINDOWS\COMMAND to the DOS directory.
3)Install BeOS P.E.
4)Make a BeOS bootdisk.
5)Delete windows (all the directories associated with Windows)
6)Run BeOS from the bootdisk.

...that what I would do, but you can maybe come up with something better

It's pitty clear the person just wants to be able to use BeOS _without_ having DOS (or DOS plus Windows) or any pother Microsoft product on his system. If the bootloader has its own file reading code then is there a means to position it at the correct drive sector to for a partition or drive?

Try borrowing a copy of Windows 9x,
install it, then install BeOS. Then
DELETE Windows ie.--reformat the
Windows partition with the BFS
filesystem. It should be legal as you
won't be USING the Windows OS but for
about 55 minutes, 50 of which will be
used to install Windows and 4 1/2 will be
used to boot it just long enough to install
BeOS from it.

If you like, though, I can set you up with a
copy of BeOS 5 Professional cheap. E-
mail me for details.

Why don't you purchase the BeOS 5 Pro CD from
Gobe.com or your local BestBuys electronics
store and support the OS you love. :-)
