    1: # How to install GRUB2 on NetBSD
    2: 
    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:
    6: 
    7: First of all, either download the package, using `pkgin install grub2`, or build 
    8: it yourself from package sources (`/usr/pkgsrc/sysutils/grub2`).
    9: 
   10: 
   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.
   14: 
   15:     # grub-mkconfig -o /grub/grub.cfg
   16: 
   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:
   21: 
   22:     Device name :   /dev/rwd0a
   23:     Direct access : /dev/rwd0d
   24: 
   25: The appropriate `grub-install` command for this drive would be:
   26: 
   27:     # grub-install --no-floppy /dev/rwd0d
   28: 
   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
   31: OS-selector.
   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.
