BootMGR (Users)

I want to thank to BTTR-software for their BootMGR.
A long time I was looking how to make dual-boot on my notebook HP Pavilion dv6
(Win7/FreeDOS).
It is quite problem because it is SATA/AHCI only without possibility to change it in BIOS. It is f.e. impossible to install there WinXP (even with various custompacs and driver collections).
I tried various warez boot managers to make dual boot to HD1/p0(win )and HD1/p1(dos) and it din't work. And then I tried BootMGR and voila, everything works fine.

What type of system do you have
DR Dos?
Windows XP?
One Hard Disk?
2+ Hard Disks?
One Partition on the Hard Disk?
2+ Partition on the Hard Disk?
Fat 32 File System?
NTFS File System?

I have a Dual Boot System That uses only Windows Boot Manager!
One Hard Disk with 2 Partitions
First Partition Windows XP on NTFS
Second Partition Dr Dos on Fat 32

WEB : http://www.winimage.com and http://www.winimage.com/bootpart.htm
Add partition in the Windows NT/2000/XP Multi-boot loader
Usage : When running under Windows NT/2000/XP or MS-Dos
BOOTPART
List all partition, with number
BOOTPART <part_number> [LBA] <filename> [<name_of_system>]
where : part_number : a number of a partition (or A: for floppy)
LBA : force LBA addressing for loading partition bootsector
filename : the file name of the bootfile to create
name_of_system : the name to be added in the BOOT.INI
Create a boot file for the partition, and if name_of_system
is specified, register it in the BOOT.INI
You can also replace <part_number> by DOS622 or WIN95 to them.
BOOTPART LIST
List entry in BOOT.INI (you can remove them after with BOOTPART)
Under MS-Dos (MS-Dos 6.22 or the "MS-Dos 7.0" from Windows 95) only:
BOOTPART <part_type> BOOT:C:
where <part_type> is DOS622, WIN95 or WINNT, rewrite the boot sector
of C: for boot under MS-Dos 6.22, Win95 or the NT Boot loader
BOOTPART REWRITEROOT:C:
Put the IO.SYS and MSDOS.SYS file from MS-Dos 6.22 at the beginning
of the boot sector
------------------------------------
BOOTPART lets you add partitions to the Windows NT Multiboot menu. Usually,
the only partitions on the Windows NT multiboot are the one or more installations of
Windows NT.

With BOOTPART, you can add any partition to the menu. You can add OS/2
Multiboot or Linux Partitions (with Lilo) to the menu.

BOOTPART creates a 512 byte file that contains an image of a boot sector
that loads the boot sector of the partition. That is, it creates a small program
that loads and executes the specified partition's boot sector.
Thereafter, this file is
declared in C:\BOOT.INI (a text file used by the Windows NT boot menu). The
boot sector comes from FDFormat and WinImage.

Note that under Windows NT, BOOTPART must be run from the Administrator account.

Example :
You create and move to a directory for the boot file, and display the
list of partitions :
C:\>MD BOOTFILE
C:\>CD BOOTFILE
C:\BOOTFILE>BOOTPART

Run "bootpart /?" for more information

2 : C: type=5 (Extended), size = 8032 KB
3 : C: type=7 (HPFS/NTFS), size = 8001 KB
4 : D: type=6 (BIGDOS Fat16), size = 261104 KB

8 : D: type=7 (HPFS/NTFS), size = 369648 KB
9 : D: type=83 (Linux native), size = 296944 KB

Note : Extended partitions (type 5) are the only partitions that can contain
other partitions. It's not useful to add extended partitions to the NT boot
menu !
The * after C: means that partition 0: is the active partition.

Now, you add some partitions :
C:\BOOTFILE>BOOTPART 9 BOOTLINX.BIN Linux
C:\BOOTFILE>BOOTPART 1 BOOTLINX.BIN Boot Manager OS/2
C:\BOOTFILE>BOOTPART a: BOOTLINX.BIN Boot floppy A:

The last line (A:) is special, and is designed for a BIOS configured for
booting from C: before reading from the floppy (A:) .

The next time you boot, the Windows NT menu will show Linux, OS/2 Boot
Manager, and the floppy !

BOOTPART is a Win32 console application written in C++ and compiled with Visual C++ 2.2
bootpa32.mak is the Visual C++ Makefile, bootpart.cpp is the source file,
bootpart.exe is the executable, and bootpart.txt is this documentation.

Fast tips : To repair the Windows NT boot sector
====================================
Windows NT installs a boot sector that lauches 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 MS-Dos 6.22 on your hard disk, on an 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:"
=======================================================================
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 can be hidden, but you can ask File Manager or Explorer to
display hidden files). Then go to the section "To have both MS-Dos
6.22 and Windows 95 in the NT menu"

Just enter these bootpart command :
BOOTPART DOS622 C:\BOOTSECT.622 "MS-Dos 6.22"
BOOTPART REWRITEROOT:C:

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.

format c: and voila : )

Yes it is good that it works, I know it is one of main reasons why people don't want to install dos and not lose their current windows. Probably grub4dos can do the same trick, at least its docs says that.

There is an old anecdote:
Year 2020. The World computer corporation (read M$) introduces a new computer with a new OS. Guests from all countries are invited. The agent of the corporation proclaims: " The new OS can do EVERYTHING, just tell the command into the microphone and it will be done! You want beer - just say 'give me beer', you want a beautiful girl, just say it and she will appear... there is no thing it cannot do!"
A gloomy russian programmer shouts from the croud : "format c: without prompt!"
