You can find other references on the net about this that have more info than I do, but it is changing. This is only directions that I know work. I'll let everyone know when I finish my latest test on the install. I'm thinking that when I had 98 and Linux togehter one time and threw on XP that I didn't have to change anything. I could boot into the NT loader and choose DOS and LILO would pop us, but I need to retest to see for sure.</p>

Here</a> is some reading ,directly from Red Hat, that gives some key points to consider. They also explain some
of what I am doing here.

<p>Operatings Systems I have used to do this include:Red Hat Linux 7.2, Windows 98se, Windows NT 4.0 Server and Workstation, Windows 2000 Professional and Advanced Server, and Windows XP build 2505(Beta) and 2600(Retail). All installs were done on a single hard drive in various systems. Someone e-mailed me that they did it with Mandrake 8.1 or 8, I forget.

<p>When installing XP/NT you must remember that most Linux distrobutions can't read a NTFS partition. So if you
want to share info between Linux and NT you're going to have to make a small fat32 partition to do so. Otherwise you
will have to compile the kernel with read-only NTFS support or go through a hassle to get it to write
to an NTFS partion. Though you can use NFTS for this process.</p>
<p>This tuturoial is not meant to teach you Linux, only
how to dual boot it with Windows. After you install XP/NT you need to install Linux, or you can install XP first. With these instructions I have put 98 first with Linux followed by XP. So it is up to you. When installing Linux <font color="FF3300">do not install LILO into the MBR</font> Install
it the first boot partion of the drive you install it into, and remember where you installed the /boot
partiton. Like /dev/hda4 or whatever. </p>
<h3>This method works for LILO. I do not use GRUb this way. I would advise you to get a newer version that has GRUB and use it to install with. It has not failed me once. But if you are in a situation and need this it is here for you.</h3>
<p align="center"><font color="FF9900" size="+2">I DO NOT RECOMMEND INSTALLING INTO THE MBR - THIS MAY FAIL IS YOU DO SO</font></p>
<br>
<p align="center"><font color="FF3300" size="+2">Make sure you make the boot disk, otherwise this process will not work.</font></p>
<br>
<h3>Note: Installing Linux , Red Hat 7.1 and down at least, have a limitation that you must install the /boot to the first 1024 sectors of the disk and your present OS installed may be bigger that that. So if installing an older verion of Linux, install it before NT or XP will keep you where you need to be, NT/XP will take the MBR anyway.</h3>
<p>Someone aksed, "Why not install into the MBR?" --- Upon initial install Red Hat will see and boot Win98 and ME from LILO, but we are using an NTFS partition and not a fat32. Although Linux can read-only NTFS, it is not recommended by most. In most cases Linux will fail to boot the NT install, even when it looks all good and you think it will. You may as well go ahead and do it right the first time rather than fdisk/mbr and adding to its headaches.</P>
<p align="center"><font color="FF3300" size="+2">Make sure you make the boot disk. Otherwise this process will not work.</font></p>
<br>
<p align="center"><font color="FF9900" size="+2">I DO NOT RECOMMEND INSTALLING INTO THE MBR - THIS MAY FAIL IS YOU DO SO</font></p>
<br>
<p>Once you have finished the Linux install make sure you can still boot XP/NT. You can? Now boot Linux
using the boot disk I told you to make. You can do that too?</p>
<p>Now you need a formated DOS floppy to use. Once you have that you can boot into Linux using your
boot floppy. Now go to the root drive (<font color="FF3300">cd /</font>) and type the following command.</p>
<center>
<font color="FF3300">df -h</font>
</center>
<p>You can 'man' the df command, bascically it will show you the current filesystem, the H
is human readable. Look for the /boot part of it.
</p>
<p>Then type the follwing command to copy the the boot sector info from the boot sector to the root of linux
</p>
<center>
<font color="FF3300">dd if=/dev/hda4 of=/bootsect.lnx bs=512 count=1</font>
</center>
<p>
the if=/dev/hda4 is supposed to be where you put the /boot partion so look at yours and replace as needed.
</p>
<p>Do an <font color="FF3300">ls</font> to see if it is there, like it is supposed to be.
</p>
<p>Now put in the dos floppy and do the following commands to mount and copy the file bootsect.lnx to the floppy
</p>
<center>
<p><font color="FF3300">mount -t msdos /dev/fd0 /mnt</font>
</p>
</center>
<p>Mounts the ms-doss floppy so you can use it.
</P>
<center>
<p><font color="FF3300">cp /bootsect.lnx /mnt</font>
</p>
</center>
<p>Copies the boot sector info to the floppy and the last command will list the floppy to ensure it is there.
</p>
<center>
<p><font color="FF3300">ls /mnt</p></font>
</center>
<p> Is it there? Good. Now unmount the floppy drive.</p>
<center>
<p><font color="FF3300">umount /mnt </font></p>
</center>
<p>Now reboot into XP/NT and go to a Dos prompt with the following command.</p>
<center>
<p align="right"><font color="CC6699">Do this from the DOS promt</p>
<p align="right">If you do this from Windows Explorer and Notepad, you will get a blinking cursor when you try to boot Linux from the boot loader.</P>
<p align="right"> Do it from the dos prompt</font></p>
<br>
<p><font color="FF3300">Start ---> run ---> cmd </font></p>
</center>
<p>This will open a dos box for your needs in editing the file <font color="3399FF">boot.ini is in the c:\ directory.</font><br>
Now let's move into the right direcoty and set the file properties to
not read-only, not system, not hidden</p></font>
<center>
<p><font color="FF3300">cd \</font></p>
</center>
<center>
<p><font color="FF3300">attrib -r -s -h boot.ini</font></p>
</center>
<p>Remember to use edit from a dos prompt here</p>
<center>
<p><font color="FF3300">edit boot.ini</P</font></font>
</center>
<p>It should look something like this.</p>
<p>[boot loader]<br>
timeout=30<br>
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT<br>
[operating systems]<br>
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect<br>
<p> Now look at the bottom of the file and add the following to it</p>
<center>
<p><font color="FF3300">c:\bootsect.lnx="Linux"</p></font>
</center>
<p>Once you add that, it should now look closer to this.</p>
<p>[boot loader]<br>
timeout=30<br>
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT<br>
[operating systems]<br>
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect<br>
c:\bootsect.lnx="Linux"</p>
<center>
<p><font color="FF3300">attrib +r +s +h boot.ini</font></p>
</center>
<center>
<font color="FF3300">Now copy the a:\bootsect.lnx file from the floppy to the root drive c:\ .</font>
</center>
<p>Simply put the floppy in the drive and copy the file a:\bootsect.lnx c:\ . Stay at the dos prompt and type the following commmand to copy it to your c:\ drive
</p> <br>
<center>
<p> <font color="FF3300"> copy a:\bootsect.lnx c:\</font>
</center>
</p>
<p>Now you should be able to reboot and have Linux as part of your XP/NT boot loader and hit Linux to boot Linux</P>
<p>This file was created in less than 5 mins so if a typo occurs I will fix as I go</P>
