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`).
10: After that, generate a GRUB configuration file, which tells GRUB the positions
11: of the operating system(s). The following command will generate such a file,
12: while adding your NetBSD system into its list.
14: # grub-mkconfig -o /grub/grub.cfg
16: Now, install GRUB into your hard drive's master boot record (MBR).
17: You have to know its device name for this step (e.g. `/dev/rwd0a`).
18: Exchange `/dev/rwd0a` with your desired device name, then change `/dev/rXXXa`
19: to `/dev/rwXXXd` to access the raw disk, as in the following example:
21: Device name : /dev/rwd0a
22: Direct access : /dev/rwd0d
24: The appropriate `grub-install` command for this drive would be:
26: # grub-install --no-floppy /dev/rwd0d
28: Hopefully, it should return : `Installation finished. No error reported.`
29: If it does so, simply reboot the system and you should be greeted by a nice
31: If not, recheck your device names, if that doesn't fix it, search the web for
32: the error message.
33: Even though there aren't that many resources about *GRUB on NetBSD*, you'll
34: find a lot of information at GNU/Linux-related sites which apply to this
35: scenario as well.
