Boot Ubuntu From NetBSD Boot-Loader
 

I Want To Have NetBSD Installed On My Copmuter But GRUB Doesn't Seem Apt To Boot NetBSD (No Pun Intended). NetBSD's BootLoader Has The Ablility To Boot To Windows.

How Could I Ether Force-Feed GRUB To Boot To NetBSD Or Use NetBSD's Bootloader To Boot To Ubuntu?

Windows is generally booted by chain loading. That is, the "OS" is Windows' own bootloader inside the partition. I believe GRUB can work fine inside a partition, so the same trick should work. I can't tell you how to configure GRUB for that, though.

Same problem here. I installed NetBSD 5.1.2 alongside Ubuntu 11.04 Natty. Grub2 (the version shipped with Natty) does not see the contents of the NetBSD slice/partition, and thus is unable to boot netbsd kernel (interestingly enough, it CAN boot NetBSD if run within QEMU!). Downgrading to the old grub (grub1) does not solve the problem -- it says it's unable to boot anything beyond certain cylinder.

Here's my grub.conf:

# grub.conf
#
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,4)/grub/splash.xpm.gz
