Hi

I am running Fedora in one computer and now I want to make some
tests. I have an 80G HD that I can add as a slave to the system.

I want to install the second HD with its own OS that I can play with
in such a way that my original OS is not disturbed.

I know maybe this is a question for a GRUB List but I wonder if
somebody else have done this and if there is a good how-to that could
guide me in this.

Thanks!

What OS will you install on the second disk? Most linuxes that I know of
will be happy to do it for you automatically. Windows may break
everything, on the other hand. You can probably search for and find a
lot of help online about this--try including the term "chainloader" in
your search.

I run basically the same setup at home, Mandrake 10 on the first disk,
Win XP on the second disk. But having Windows installed first was the
key; Mandrake found it and set up grub for me. I have a feeling if
Mandrake were there first, the Windows install would wreck the MBR.

I have FC2 currently on disk1

I wanted to intall a new FC2 on disk2 and experiment with Slashcode. It
requires
some special setup on Apache and Mod Perl, that's why I do not want to
experiment on
my main system.

Honestly, if it were me, I would just run the install, tell it to install to that second disk, and let the installer update the MBR & grub for me. It'll see the other OS on the other drive and try to handle it for you, automatically. I know you're getting advice to do it other ways, but I bet just letting the installer handle it will work.

Once I had a problem and had to go fix grub myself. That was a while ago, with a RH9 + Windows 98 dual-boot system. It wasn't the hardest thing to do, even though I had never tried it before. If your current install on disk1 is doing something really important, I would recommend reading about grub config first, so you know what to expect, but there's a very good chance the installer will just get it right.
