1: # How to install GRUB2 on NetBSD
3: This how-to explains the steps needed to install GRUB2 on an existing i386/AMD64
4: NetBSD-installation. The steps should work on a properly chroot'ed system too.
5: Tested on NetBSD 6.0 AMD64:
7: First of all, either download the package, using `pkgin install grub2`, or build
8: it yourself from package sources (`/usr/pkgsrc/sysutils/grub2`).
11: After that, generate a GRUB configuration file, which tells GRUB the positions
12: of the operating system(s). The following command will generate such a file,
13: while adding your NetBSD system into it's list.
15: # grub-mkconfig -o /grub/grub.cfg
17: Now, install GRUB into your hard drive's master boot record (MBR).
18: You have to know it's device name for this step (e.g. `/dev/rwd0a`).
19: Exchange `/dev/rwd0a` with your desired device name, then change `/dev/rXXXa`
20: to `/dev/rwXXXd` to access the raw disk, as in the following example:
22: Device name : /dev/rwd0a
23: Direct access : /dev/rwd0d
25: The appropriate `grub-install` command for this drive would be:
27: # grub-install --no-floppy /dev/rwd0d
29: Hopefully, it should return : `Installation finished. No error reported.`
30: If it does so, simply reboot the system and you should be greeted by a nice
32: If not, recheck your device names, if that doesn't fix it, search the web for
33: the error message.
34: Even though there aren't that much resources about *GRUB on NetBSD*, you'll
35: find a lot of information at GNU/Linux-related sites which apply to this
36: scenario as well.
