Tired of poor performance in Windows Vista? Want to rollback to Bug Free Windows XP?

If you have purchased your laptop with Windows Vista, It doesn't support you to install Windows XP by default. Dont need to panic. It requires easy steps to resolve it.

Just restart your PC and go to BIOS settings. (While you restart press F2 to enter into BIOS settings - Key Differs based on the manufacturer, Check the manual how to enter into BIOS)

There you can see "Onboard Devices" (differs based on the bios version, so if you are not able to find onboard devices, just search for the following in any submenu) Select it. In the submenu you can see "SATA Operations" Just select and press Enter. Right side you will have two options "ATA" & "AHC1". Your computer must be in the AHC1 mode. That is the reason you are not able to boot through XP installation CD. So what you have to do is, Just select "ATA" and press enter. Now press ESC key in the keyboard. Select "SAVE & EXIT" from the bios settings.

Now put the Windows XP installation CD in your media drive and choose the boot menu from the CD. You will be able to boot through XP without any hassle... Have fun with XP.
