How to install Windows XP in a vista notebook (dual system startup)

For Windows XP, you need to change a small setting, which has nothing to do with the CPU, mainly related to the SATA hard disk. if you do not have a Windows XP installation CD integrated with the SATA driver, you can set the hard disk mode to "ide" in the BIOS hard disk settings. installing two independent systems will not significantly affect the running speed. Relatively speaking, the operating system installed in the second partition will be slightly slower. however, if your laptop is installed with Windows Vista and Windows XP is installed in the second partition, Windows XP cannot be started after Windows XP is installed, and the boot menu is invisible. the solution is to first enter Windows XP, then put the Vista installation CD into the optical drive, click "start" menu-"run" command, enter "cmd" and press enter to open the command prompt. enter "X:" in the command prompt and press enter ("X:" For your drive letter or virtual drive letter). Then enter "CD Boot" and press Enter, enter "bootsect/nt60 sys" and press Enter. restart the computer to implement Windows XP and Windows Vista is enabled.
