Hello friends this is a tip to make your xp boot first.First of all, this tweak only apply to those who only have one HDD on their primary IDE channel (nothing else on device 0 or 1) and a CD-ROM and/or DVD-ROM on the secondary IDE channel.
Each time you boot Windows XP, there's an updated file called NTOSBOOT-*.pf who appears in your prefetch directory (%SystemRoot%Prefetch) and there's no need to erase any other files as the new prefetch option in XP really improves loading time of installed programs. We only want WindowsXP to boot faster and not decrease its performance. , result in an EXTREMELY fast bootup:
1. Open notepad.exe, type "del c:windowsprefetch tosboot-*.* /q" (without the quotes) & save as "ntosboot.bat" in c:
2. From the Start menu, select "Run..." & type "gpedit.msc".
3. Double click "Windows Settings" under "Computer Configuration" and double click again on "Shutdown" in the right window. 4. In the new window, click "add", "Browse", locate your "ntosboot.bat" file & click "Open".
5. Click "OK", "Apply" & "OK" once again to exit.
6. From the Start menu, select "Run..." & type "devmgmt.msc".
7. Double click on "IDE ATA/ATAPI controllers"
8. Right click on "Primary IDE Channel" and select "Properties".
9. Select the "Advanced Settings" tab then on the device 0 or 1 that doesn't have 'device type' greyed out i.e disabled , select 'none' instead of 'autodetect' & click "OK".
10. Right click on "Secondary IDE channel", select "Properties" and repeat step 9.
11. Reboot your computer.

BAD IDEA
Few people who read this "tip" will understand what it does. I do, and it is not pretty. It is an ugly hack which will do the opposite of what is claimed.
Steps 1-5 will create a script that will delete the "NTOSBOOT-B00DFAAD.pf" file on every shutdown. This file is used to guide the boot prefetch operation that takes place during the moving bar animation. If the file is deleted this can not take place and the animation will take very little time. This is what convinces many people that the boot process is faster. Don't be fooled.
The files that were normally loaded during prefetch must be loaded. If this can not be done by prefetch, it will be done later on during the boot sequence. But now it will be done much less efficiently and take longer. If the boot process is timed with a stop-watch it will be clearly seen that it is slower.
Steps 6-10 will remove a small delay during boot. This will partially offset the damage done in steps 1-5. It will disable a second HD or CD if present.
Don't be fooled like the author was, give this "tip" all the attention it deserves - none.
