If you did not make backup copy of installation CD, this is how to make it bootable if your CD is still readable.
1. Create folder named XPSETUP, XPSETUPBOOT on C: drive.
2. Download http://www.nu2.nu/download.php?sFile=wxp10.zip file into C:\XPSETUPBOOT folder.
3. Unzip wxp10.zip file then copy proper w2ksect.bin file to C:\XPSETUPBOOT folder( XPHome and XPPro has different file, so copy the proper one.)
4. Download ImgBurn CD Burning software and install it.
5. Copy everything from installation CD to C:\XPSETUP folder. ***Write down the label name of the CD such as WXHOEM_EN.
6. Start the ImgBurn, make the CD Bootable, use the bin file C:\XPSETUPBOOT\w2ksect.bin that you copied in step 3.
7. Add the folders and files in the C:\XPSETUP folder.
(This is 2 step process, adding folders then adding files).
8. Use the label name you wrote down in step 5 as cd label.
9. Start burning. It might ask you to change some settings since it contains I386 folders, allow it to change it.
