Do you mean it replaces the existing MBR with it's own implementation?
Yes.

If I understand correctly MBR's are not all the same. Different OS may write it differently. And if I reinstall the OS on my first partition, and it's e.g. Windows, it's going to write its own version of an MBR, correct?
Right.

I need more technical doc on GRUB. The manual over at GNU is being rewritten I guess and is "unifinished".
A few things, then..

GRUB is, for a bootloader, very large and complex. Most of the program is not in the boot sector, but in ordinary files stored on a partition in the system. When GRUB boots, the code in the boot sector will find and load the rest of the program, which loads a config file, which instructs it what menu options to display. It can do things like load other bootloaders -- necessary for things like MS Windows -- or make the relevant partition look active before booting something.

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.
