I've decided on some basic principles for my use of bootloaders.

1. Use the bootloader built for the given OS. For MS Windows, use their bootloaders (NTLDR, or whatever they're called). For Linux, use their bootloaders (LILO, GRUB). And for BSD, use their bootloaders (I've switched to NetBSD).

2. Switch OS booting by changing boot flag, using tools on the OS (e.g. parted in Linux, fdisk -a in NetBSD, etc.)

3. Do not(!) use Microsoft's diskpart tool to change boot flags if you're using other OS's. There is a win32 tool I found on a PLoS Linux distro that I like.

I experimented with GRUB. But in my experience it is not as stable, nor as fast, as using the native bootloaders. I prefer to learn to use the bootloaders than to try to use GRUB as a "universal" bootloader. GRUB prefers to use the native bootloaders for other OS's anyway.

In sum, I use boot flag switching and unfettered booting, not chainloading with a "man in the middle" (GRUB).

parted

PARTED(8)							 GNU Parted Manual							 PARTED(8)

NAME

       GNU Parted - a partition manipulation program

SYNOPSIS

       parted [options] [device [command [options...]...]]

DESCRIPTION

       parted  is  a program to manipulate disk partitions.  It supports multiple partition table formats, including MS-DOS and GPT.  It is useful
       for creating space for new operating systems, reorganising disk usage, and copying data to new hard disks.

       This manual page documents parted briefly.  Complete documentation is distributed with the package in GNU Info format.

OPTIONS

       -h, --help
	      displays a help message

       -l, --list
	      lists partition layout on all block devices

       -m, --machine
	      displays machine parseable output

       -s, --script
	      never prompts for user intervention

       -v, --version
	      displays the version

       -a alignment-type, --align alignment-type
	      Set alignment for newly created partitions, valid alignment types are:

	      none   Use the minimum alignment allowed by the disk type.

	      cylinder
		     Align partitions to cylinders.

	      minimal
		     Use minimum alignment as given by the disk topology information. This and the opt value will use layout information  provided
		     by the disk to align the logical partition table addresses to actual physical blocks on the disks.  The min value is the min-
		     imum alignment needed to align the partition properly to physical blocks, which avoids performance degradation.

	      optimal
		     Use optimum alignment as given by the disk topology information. This aligns to a multiple of the physical block  size  in  a
		     way that guarantees optimal performance.

COMMANDS

       [device]
	      The block device to be used.  When none is given, parted will use the first block device it finds.

       [command [options]]
	      Specifies the command to be executed.  If no command is given, parted will present a command prompt.  Possible commands are:

	      help [command]
		     Print general help, or help on command if specified.

	      align-check type partition
		     Check if partition satisfies the alignment constraint of type.  type must be "minimal" or "optimal".

	      mklabel label-type
		     Create  a	new  disklabel	(partition table) of label-type.  label-type should be one of "aix", "amiga", "bsd", "dvh", "gpt",
		     "loop", "mac", "msdos", "pc98", or "sun".

	      mkpart part-type [fs-type] start end
		     Make a part-type partition for filesystem fs-type (if specified), beginning at  start  and  ending  at  end  (by  default	in
		     megabytes).  part-type should be one of "primary", "logical", or "extended".

	      name partition name
		     Set the name of partition to name. This option works only on Mac, PC98, and GPT disklabels. The name can be placed in quotes,
		     if necessary.

	      print  Display the partition table.

	      quit   Exit from parted.

	      rescue start end
		     Rescue a lost partition that was located somewhere between start and end.	If a partition is found, parted will  ask  if  you
		     want to create an entry for it in the partition table.

	      resizepart partition end
		     Change the end position of partition.  Note that this does not modify any filesystem present in the partition.

	      rm partition
		     Delete partition.

	      select device
		     Choose  device  as  the current device to edit. device should usually be a Linux hard disk device, but it can be a partition,
		     software raid device, or an LVM logical volume if necessary.

	      set partition flag state
		     Change the state of the flag on partition to state.  Supported flags are: "boot", "root", "swap",	"hidden",  "raid",  "lvm",
		     "lba", "legacy_boot", "irst", "esp" and "palo".  state should be either "on" or "off".

	      unit unit
		     Set  unit	as the unit to use when displaying locations and sizes, and for interpreting those given by the user when not suf-
		     fixed with an explicit unit.  unit can be one of "s" (sectors), "B" (bytes), "kB", "MB", "MiB", "GB", "GiB", "TB", "TiB", "%"
		     (percentage  of  device size), "cyl" (cylinders), "chs" (cylinders, heads, sectors), or "compact" (megabytes for input, and a
		     human-friendly form for output).

	      toggle partition flag
		     Toggle the state of flag on partition.

	      version
		     Display version information and a copyright message.
