Reconfiguring Grub after installing second flavour.

HI, guys,

I've got a spare partition and want to throw Gentoo on it.  This will overwrite my Grub.  Arch is my permanent flavour (obviously), so I want it to 'own' Grub.  Once I have installed Gentoo, what is the best way to give Grub ownership back to Arch?

Looking at the problem from another angle.  Would it be better if I installed Gentoo, but didn't do the Grub bit? I could then theoretically boot into Arch and then have Grub point at Gentoo, also.

Anyone been down this road and found the best solution?

Cheers,

Chris.

If you install Gentoo from stage3, I don't think that there is gonna be any Gentoo's grub automatically installed somewhere.

Hmmm, wouldn't that leave most Gentoo users unable to boot?

Re: Reconfiguring Grub after installing second flavour.

In case gentoo *does* install grub into the MBR, the way to give control back to Arch from gentoo is:

$ grub

      GNU GRUB  version 0.97  (640K lower / 3072K upper memory)

 [ Minimal BASH-like line editing is supported.  For the first word, TAB
   lists possible command completions.  Anywhere else TAB lists the possible
   completions of a device/filename. ]

grub> root (hdX,Y)
grub > setup (hdX)
grub > quit

where (hdX,Y) is the boot partition of Arch in grub notation.

Good ideas do not need lots of lies told about them in order to gain public acceptance.

Re: Reconfiguring Grub after installing second flavour.

Many thanks.  I think i will install Gentoo, but exclude the Grub step.  I will hopefully be able to boot Arch hen and use grub to point to my hda3 partition.

Hopefully this will work.
Cheers,

Chris.
