Yes 1st before you start your PC INSERT YOUR XP DISK IN DRIVE. If your PC start from CD then you be fine just follow the INSTRUCTION but if your PC do not start from CD then you have to tell your BIOS 1st BOOT Device is CDROM.
To do this start your PC and start pressing the DEL key on your Keyboard. This will help you to ENTER BIOS SETTINGS. Look for 1st BOOT DEVICE it could be FLOPPY OR HDD AND LAST WILL BE CDROM.
Now here if you have FLOPPY CHANGE THAT TO CDROM AND SAVE AND EXIT BIOS.
IF YOU HAVE HDD THEN CHANGE THAT TO CDROM AND SAVE AND EXIT
THIS SHOULD START YOUR CDROM AS 1ST BOOT DEVICE.
