You definitely can. The usual gentoo install is based on the support of
another system, being that gentoo or debian makes no difference as long as
you can chroot at some point.
But i think you might have some problems if you want to install a 32bit
gentoo from a 64bit system. If that's not your case you should be safe...

Hello Alex,

I installed it from Ubuntu which is similar to Debian. While doing
that I did rework the german Wiki page not long ago.

http://de.gentoo-wiki.com/wiki/Installation_von_Gentoo_Linux

It was helpfull for me. Now it should be even more up-to-date.

Al

You can control the master boot record only from one partition. If
Debian already has it (and is your main system) I would adapt it
there.

If you install it into experimental Gentoo and break it, you will not
even be able to boot Debian.

That's not my question, problem was adding Gentoo to grub2 config, it
was'nt found by grub2-script and not added to the list. But i will see
in a few minutes how it comes.

I suggest you try first on virtual environment before breaking anything
- virtualbox for example...

For creating 32bit gentoo on 64bit debian use /usr/bin/linux32 before
you chroot to gentoo stage root.

So the plan I see is:

1. create gentoo on server (linux32, chroot, compile, emerge -e world,
etc). You can always recompile world with another set of CFLAGS if you
have different machine, so set CGLAGS for generic 686
2. create experimental environment with debian and compiled gentoo in
virtualbox
3. learn about problems (bios, grub, grub2, backup copies)
4. do it :)

good luck

You can even do it from Windows if you feel that way inclined.

All an installer does is write a bunch of files to known names on a disk. It 
does absolutely nothing else. All you'd need Windows to do is:

have a driver for the filesystem you want Gentoo to run on
make valid partitions and filesystems, then write to them
run portage correctly

This is all the installer ever does.
it's also what wubi does.

Grub2 is more complex than Grub1. A whole directory of configurations
from which the actual configuration is finally generated. Read some
tutorial here.

Gentoo wasn't detected automatically from Ubuntu. I needed to
configure it manually following the Gentoo handbook.

Grub2 (or os-prober) can't find Gentoo installs. You have to add it manually or 
add a script that generates the Gentoo entry "blindy".
