Several people have mentioned having problems opening the attachments so I am going to post the contents here instead; first up is Win 9x & Win 2000.

How to Dual-Boot Windows 9X/Me and Windows 2000 Pro
Updated: 06/26/2004
Introduction
These instructions provide step-by-step directions for installing both Windows 98SE and Windows 2000 Pro (hereinafter referred to as Win9x & Win2K) on the same hard disk drive so that either operating system can be selected when the computer first boots-up.
While it is possible to install Win2K first then Win9x, it is much more difficult and not recommended or explained here; this describes the installation of Win9x first, then Win2K.
Note: Multi-boot configurations with Windows 95/Me and Windows NT/XP are implemented in a similar fashion.
Overview
Use a Windows 98 startup disk to fdisk and format the hard drive.
Create and format one partition (for Win9x), leaving some unpartitioned space (for Win2K).
Copy Windows 98 files onto the HDD and install Windows 98.
Use the Win2K CD to create and format a new partition in the unpartitioned space.
Install Win2K.
Install software and test system.
Step-by-Step Instructions
-- Caution --
If using a disk drive that has data on it, it is highly recommended that the data be backed-up before proceeding as everything on the drive will be deleted.
Preparation of the hard disk drive (HDD)
• Check the BIOS to make sure it is set to boot in this order: Floppy, CD/DVD, HDD (or IDE0).
• Put a Windows 98 startup floppy disk in the floppy drive and boot/reboot the computer.
• Start without CD support when asked (no need for it yet and it just takes longer, but it won’t hurt anything if it starts automatically).
• Click Yes to enable large hard disks whenever asked.
• Use fdisk to delete all existing partitions (don’t forget to check for non-DOS partitions).
• Use fdisk to create one partition, but leave enough space for Win2K to be installed on another partition which will be created later.
• Set this partition as active.
• Press Esc, usually 3 times, to get back to the a:\> prompt, and then reboot (Ctrl-Alt-Del).
• Start without CD support again when asked.
• Format the partition just created; include the “s” switch (/s) in your command, i.e. format c: /s (this switch transfers system files that allow the disk to be booted).
• Press Esc, (3 times), to get back to the a:\> prompt, then reboot (Ctrl-Alt-Del).

Install Windows 98SE (Wizard instructions NOT included)
Install Win9x before Win2K (if installed after, it will overwrite the C:\BOOT.INI file and not allow a dual-boot).
Boot (or reboot) with the Win98 startup disk. Whenever asked, start with CD support.
When you get to the command prompt, look a few lines above it for one that says something like “Drive X: = Driver MSCD001 unit 0”… X will be the CD drive letter.
• Make a directory on the C drive to copy the 9x files into using the command:
o A:\>md c:\win98se (space before “c”). Press Enter.
• Put the Win9x installation CD into the DC drive.
• Copy files from the CD into the C drive directory you created using the command:
A:\>copy x:\win98\*.* c:\win98se (where x is the drive letter for the CD drive (note the spaces before “x” and before “c”). Press Enter.
• After all files have been copied, the command prompt will return. Remove the CD, but not the floppy, and reboot (Ctrl-Alt-Del).
• Start the Win9x installation with the command:
o A:\>c:\win98se\setup.exe (no spaces). Press Enter.
Note: If the installation does not start, use the command A:\>rd c:\win98se, then go back to the “Make a Directory” section above and start over; make sure your disk is clean, not scratched, and that you are copying from the correct drive. If the installation starts, continue:
• Remove the floppy disk; follow the on-screen instructions to install Win9x.
o Have the Product Key ready to enter when requested.
o Have a watch or clock handy to set the correct time when asked.
o Allow the computer to reboot as necessary to detect and install available device drivers. When asked to specify a location for drivers, browse to the C:\Windows folder unless there is a floppy or CD.
• When Windows has finished installing, Right-click in any open area on the desktop, click on the Screen Saver tab, click on the Settings button. Set System standby, Turn off monitor, and Turn off hard disks to Never (this can be revised later). Click Apply, then OK, and OK.
Optional but Recommended – run ScanDisk (click Thorough and Automatically fix errors) to make sure HDD doesn’t have any errors (this may take awhile).
Optional – run Defragment Now to make sure OS files are contiguous (shouldn’t take too long at this point).
• Close any open windows, and then install the motherboard drivers (should be on a CD that came with your motherboard/computer, but may be on a Restore disk).
• Right-click on My Computer, click Properties, click on the Device Manager tab.
o Install/reinstall drivers for any devices that are shown to have a problem.
• Install an anti-virus program. A firewall is recommended as well.
• Use Internet Connection Wizard to setup internet access.
• Use Windows Update to download patches and security updates (click Start, and Windows Update should be at the top of the list).
• Update anti-virus program and run it.
• Run Disk Cleanup to delete any unneeded items left over from the preceding steps.
• Run Disk Defragmenter (recommended but not required).
• Install and run another program to make sure everything is working properly.
After Windows 98 has been installed and is working well, the next step is to install Windows 2000.

Install Windows 2000 Professional (Wizard instructions included)
Boot to Win9x. Close any programs that are running and disable the anti-virus program.
Insert the Win 2K CD into your CD drive. It should autostart and display the following message:
This CD contains a newer version of Windows than the one you are presently using. Would you like to upgrade to Windows 2000?
• Click Yes even though we will not actually be upgrading. The following error message may pop up:
The option to upgrade will not be available at this time because Setup was unable to load the file c:\WINDOWS\UpgDlls\w95upg.dll\WIN9XUPG\W95UPG.DLL.
The system cannot find the file specified.
Ignore this message, if it shows up, by clicking OK.
• The next message will say:
Welcome to the Windows 2000 Setup Wizard....
What do you want to do?
o Upgrade...
o Install a new copy of Windows 2000 (Clean Install)...
• Select the second choice (Install new) and click Next.
• Accept the agreement.
• Enter the product key.
• In the resulting window click the Advance Options button to generate the following screen:
Advanced Options
You can select options to customize setup
Location of Windows 2000 files
E:\I386
\WINNT
Copy all setup files from the CD to the hard drive
I want to choose the installation partition during setup
Check both boxes. Default location for the Win 2K files should be acceptable.
Click OK. A Select Special Options window will pop up. Use this to add any languages other than English, add accessibility features, or change the options from the last step. When done, click Next. Setup will then copy files to the hard disk drive and restart the computer.
When it restarts, select Windows 2000 Setup from the options.
Setup will then boot to the following screen (or something similar):
Windows 2000 Professional Setup
===========================
Welcome to Setup.
This portion of the Setup program prepares Microsoft Windows 2000 to run on your computer.
• To set up Windows 2000 now, press ENTER.
• To repair a Windows 2000 installation, press R.
• To quit Setup without installing Windows 2000, press F3.
Press ENTER on the keyboard to continue.
Windows 2000 Professional Setup
===========================
The following list shows the existing partitions and unpartitioned space on this computer.
Use the UP and DOWN ARROW keys to select an item in the list.
• To set up Windows 2000 on the selected item, press ENTER.
• To Create a partition in the unpartitioned space, press C.
• To delete the selected partition, press D.
xxxxxx MB Disk 0 at ID 0 on bus 0 on atapi:
C: FAT 32 xxxxxx MB (xxxxx MB free)
Unpartitioned space xxxxxx MB
Scroll down to the unpartitioned space with the arrow key and press C to create a new partition in the free (unpartitioned) space.
Note: xxxxxx will vary depending on the size of your hard drive and existing partitions.
Windows 2000 Professional Setup
===========================
You asked Setup to create a new partition on xxxxxx MB Disk 0 at Id 0 on bus 0 on atapi.
• To create the new partition, enter a size below and press ENTER.
• To go back to the previous screen without creating the partition, press ESC.
The minimum size for the new partition is 8 megabytes (MB).
The maximum size for the new partition is xxxxxx megabytes (MB).


Enter the partition size and Press ENTER on the keyboard.
Note: To create additional partitions now, enter appropriate sizes before continuing.
The new partition will be created and this screen will return with the new partition included:
Windows 2000 Professional Setup
===========================
The following list shows the existing partitions and unpartitioned space on this computer.
Use the UP and DOWN ARROW keys to select and item in the list.
• To setup Windows 2000 on the selected item, press ENTER.
• To Create a partition in the unpartitioned space, press C.
• To Delete the selected partition, press D.
xxxxxx MB Disk 0 at ID 0 on bus 0 on atapi:
C: FAT 32 xxxxxx MB (xxxxx MB free)
E: New (Unformatted) xxxxxx MB
Unpartitioned space xxxxxx MB
Unpartitioned space 8 MB

Scroll down to E: (the new partition) with the down arrow key and press ENTER to install Win2K on this partition.
Windows 2000 Professional Setup
===========================
The partition you selected is not formatted. Setup will now format the partition.
Use the UP and DOWN ARROW keys to select the file system you want, and then press ENTER.
If you want to select a different partition for Windows 2000, press ESC

Format the partition using the NTFS file system.
Format the partition using the FAT file system.
The choice now needs to be made as to which file system to use. NTFS is recommended because it is more stable and uses space more efficiently. But Win 9X cannot access files on NTFS formatted partitions; Win 2K can access both format types. In order to access files on the Win2K partition from the Win9x partition, FAT needs to be selected. If Win9x will not need to access Win2K files, choose NTFS. If unsure, use FAT for now; it can be changed to NTFS later if desired, but once NTFS is used, there’s no going back to FAT.

Using the arrow keys, scroll to the appropriate file system and press ENTER (FAT was selected for this example).

Windows 2000 Professional Setup
===========================
Because the partition is greater than 2048 megabytes (MB), Setup will format it with the FAT32 files system.
Files stored on this partition will not be available when you are using other operating systems, such as MS-DOS or some versions of Windows.
• To continue and format the partition, press ENTER.
• To go back to the previous screen without having Setup formatting this partition, press ESC.
• To quit Setup, press F3.
Press ENTER to format the partition.
This will generate a screen showing the format progress. The following screen will examine the disk and proceed to install Win 2K.
After Windows 2000 has installed, the system will reboot to this screen:
Please select the operating system to start:
Microsoft Windows 2000 Professional
Microsoft Windows
Use ↑ and ↓ to move the highlight to your choice.
Press Enter to choose.
Seconds until highlighted choice will be started: 29
For troubleshooting and advanced startup options for Windows 2000, press F8
The first choice, Windows 2000, is highlighted and the system will boot to that automatically if another selection is not made within the time limit. The other start up option, Windows, will be Win9x.
At this point, select Win2K and press Enter.
Right-click in any open area on the desktop, click on the Screen Saver tab, click on the Settings button. Set System standby, Turn off monitor, and Turn off hard disks to Never (this can be revised later). Click Apply, then OK, and OK.
Optional – run Defragment Now to make sure OS files are contiguous (shouldn’t take too long).

Close any open windows, and then install the motherboard drivers (should be on a CD that came with your motherboard/computer, or may be on a Restore disk).
• Right-click on My Computer, click Properties, click on the Device Manager tab.
o Install/reinstall drivers for any devices that are shown to have a problem.
• Install an anti-virus program. A firewall is recommended as well.
• Use Internet Connection Wizard to setup internet access.
• Use Windows Update to download patches and security updates (click Start, and Windows Update should be at the top of the list).
• Update anti-virus program and run it.
• Run Disk Cleanup to delete any unneeded items left over from the preceding steps.
• Run Disk Defragmenter (recommended but not required).
• Install and run another program to make sure everything is working properly.
After Windows 2000 has been installed and is working properly, additional partitions can be created in any free space that was remaining on the hard disk drive.
To create and format additional partitions:
• Boot to Windows 2000.
• Right-click on My Computer.
• Click on Manage.
• On the left side (the “Tree” pane), click on Disk Management.
• Maximize the window if necessary to make viewing easier.
• Right-click in the area identified as Free Space.
• Click on Create Logical Drive…
• A wizard pops up describing what will be happening; click Next.
• Logical drive should be your only option; click Next.
• Type in the size of the partition in MB; click Next.
• Unless you know what you’re doing, it’s best to leave the default option: Assign a drive letter. Leave the default letter or change it as desired. Click Next.
• If the partition isn’t formatted it won’t be usable. So the only reasonable choice here is to format. The file system then needs to be identified, as explained earlier, either can be used.
• Type in a name for the partition.
• Quick format can be selected if time is limited, but a full format is generally preferred.
• The partition will then be formatted.
Repeat this process until all free space is being utilized.
