You should be able to follow the default gentoo instructions, and run grub-install /dev/hda - someone else back me up on this, but I'm pretty sure that won't "wreck" the windows installation. instead, it will install the grub code in the MBR of the first hard disk, so grub will come up on startup. then, grub *should* be able to load linux off the second hard drive, or pass control to the windows partition.

this is making the assumption that grub itself can boot off the second hard drive... in any case, grub-install just puts the grub code in the MBR (I *think* that's all it does) so the worst thing that can happen, in the case that grub is still subject to the BIOS limitations, is that you'll still only be able to boot from hda. (I believe I'm correct about this part at least -- assuming the grub.conf is set up properly, with the chainloader +1 line as described in the gentoo install docs, the system will still be able to boot the windows partition on hda.) You're just replacing the MS bootloader with grub; windows itself will still boot fine assuming a proper bootloader is in place -- this is the reason dual-booting even works at all, in fact.

I'm about half way through a Gentoo install and Grub is starting to give me headaches.
My problem is that I have 2 hard drives hda is a windows install and hdb is Gentoo and
my BIOS only gives me the option to boot from the primary hard drive (hda).  So I guess
my question is how do I install Grub on hda with out wrecking windows?  Oh and just to
clarify I am POSITIVE that I can only boot from the primary drive (its a stupid old Dell
motherboard that hasnt had its firmware updated in a long time).

Thanks,
