Re: Dual boot with dos on floppy

DOS (Disk Operating System) is, as the name implies, an OPERATING SYSTEM.
Just as four tires and a steering wheel does not constitute an automobile, a
few DOS system files does not constitute an Operating System.
Hint #1: The Disk Operating System upon which Windows 95 rides upon will NOT
fit on a single floppy disk.
Hint #2: The Command Line Interface included with Windows NT/XP/2003 is NOT
Windows DOS.
Hint #3: You will need to create a FAT partition on your hard drive if you
wish to install DOS.

Hi,

I would like to build a boot floppy disk (which will become a CD after
validation) with MS-DOS on IT.
It would first boot and propose to choose between:
-WinXP (on hard drive)
-DOS (on the floppy)
(The idea is to make a boot CD which would permit to get dos on any PC and
booting XP without having to take the CD/floppy out.)

I made my disk like that:
1) I did format it under XP to get the proper MBR on it.
2) I placed boot.ini, NTDLR and NTDETECT.COM on it so that it boots and
propose to choose.
3) I placed the WinME boot disk files (autoexec.bat, command.com,
config.sys, io.sys...)
4) I extracted the WinME MBR and placed it as BOOTSECT.DOS on the
floppy

Here is my boot.ini
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="WinXP" /fastdetect
/NoExecute=OptIn
A:\BOOTSECT.DOS="DOS" /win95dos

I thought it would be ok (and it works perfect for WinXP), but when I
choose DOS, I got an error on <windows root>\system32\hal.dll

What is wrong with this boot disk?

Thanks for your help

Cheers

Alex
