BootPart 2.60: Boot Partitions for WinNTBootPart is an easy tool for adding additional partitions to the Windows NT multi boot menu (for example, add the OS/2 boot manager or a Linux partition).
Bootpart 2.60 is compatible with Windows NT, Windows 2000 and Windows XP.
You may download BootPart 2.60 by ftp or http :The files below are standard zip file. You can use PKZip, WinZip, InfoZip or MimarSinan Codex Suite 2002 tools to decompress them.

BOOTPART lets you add partitions to the Windows NT/2K/XP Multiboot menu. Usually,
you will only have a MSDOS or Windows 95 entry and one (or
several) Windows NT entries on this boot menu.
With BOOTPART, you may add any partition to the menu. You may add an OS/2
Multiboot partition, or a Linux Partition (with Lilo) to this menu.
The only thing I highly suggest is : your active partition on your first hard disk must be a FAT16 primary partition. This may be a small partition.
It seems it's actually impossible add an HPFS partition with
OS/2 boot. If you find a workaround, please let me know.
BOOTPART creates a 512 byte file which contains an image of the boot sector
that loads the boot sector of the partition. After, this file
is declared in C:\BOOT.INI (a text file used by the Windows NT
boot menu). The boot sector itself comes from FDFormat and WinImage.
The current version 2.50 now
has very cool features : repair the Windows NT loader boot
sector on Fat partitions (but Bootpart cannot perform the repair running under Windows NT/2K/XP), easily add both MS-Dos 6.22 and Windows 95 to
the boot menu, support FAT32 partitions and disks over 4 GB, LBA support (for disk over 8 GB)...
Bootpart is a free tools. But if it saved you a lot of time and a lot of money, you can make a donation with Paypal (or buy WinImage or SmartVersion). Don't forget also send a postcard (see documentation)
Repairing the Windows NT/2k/XP boot sector on a Fat partition
Windows NT installs a boot sector that launches NTLDR and displays the Windows NT boot menu. If you lose this boot sector, BootPart can restore it.
Boot under MS-Dos (this can be a copy of MS-Dos 6.22 on your hard disk, on a MS-Dos bootable floppy, or the "MS-Dos 7.0" included in Windows 95 (you can obtain it by pressing Shift+F5 when Win95 loads). Then, enter the command :
BOOTPART WINNT BOOT:C:
If you want to remove the WinNT boot sector, you can replace
it with the command "BOOTPART DOS622 BOOT:C:"
or "BOOTPART WIN95 BOOT:C:"
How to have both MS-Dos 6.22 and Windows 95 in the NT menu (forget F4 !)
The standard situation for a computer that multiboots to
Windows NT, Windows 95, or MS-Dos 6.22 is : the user selects a
"Windows 95" entry in NT menu, and, then must press F4
if he wants to boot MS-Dos 6.22. If you don't have this situation
(i.e. : you don't have both Win95 and MS-Dos 6.22 on your system,
but want to have both), see the next section.
Just enter these BootPart commands :
BOOTPART DOS622 C:\BOOTSECT.622 "MS-Dos 6.22"
BOOTPART WIN95 C:\BOOTSECT.W95 "Windows 95"
The last line (REWRITEROOT:C:) MUST BE EXECUTED UNDER MSDOS, and moves the MS-Dos IO.* and
MSDOS.* files to the beginning of the root directory, which is required
for successful operation.
You may visit the page : http://www.bcpl.net/~dbryan/directboot.html for
obtaining more information on triple booting WinNT/Win95/DOS.
If you have WinNT & Win95 and you only want to add MS-Dos
Take an MSDos 6.22 floppy, copy the files IO.SYS,
MSDOS.SYS, and COMMAND.COM to C:\ as IO.DOS, MSDOS.DOS, and COMMAND.DOS (warning
: these files may be hidden, but you can
tweak some settings to make File Manager or Explorer to make them
display hidden files). Then follow the instructions in the section section
"How to have both MS-Dos 6.22 and Windows 95 in the NT
If you have WinNT & MS-Dos and you only want to add Win95
Install Win95 in a new directory (start the install under MS-Dos 6.22 or Windows
3.1) and then follow the instructions in the section "How to have
both MS-Dos 6.22 and Windows 95 in the NT menu"
How to add OS/2
Unfortunately, I can't directly add an OS/2 partition by itself (if
you have a workaround or fix, I'd be happy to hear about it
!). Install the OS/2 Boot Manager (you need 1 MB free on your first
hard disk), add the OS/2 partition in the boot menu with automatic
startup (0 seconds wait time), and then add the OS/2 Boot Manager
partition to your NT menu with BootPart. Sometimes, when you
install the OS/2 Boot Manager, it becomes the active partition of
your first hard disk. You can use FDISK to set the partition with
NT boot manager as the active partition later.
How to add Linux
For Linux, you must install Lilo at the beginning of the Linux partition (as is the
case with the OS/2 boot manager) and then add the Linux
partition with BootPart:
When you install Linux or run liloconfig, select "Superblock of the root linux partition" as the location for Lilo. On my own Linux box, this added the line "boot=/dev/sdb4" into the file /etc/lilo.conf
If you want mount your NTFS partition under Linux, visit the NTFS for
