Dear Sir,
Indeed your information is unique about how to install 2nd OS on the pre-installed Windows Vista.
But unfornately i have failed to install another OS (XP) on my laptop which came with pre-installed Windows Vista. I have able to make another partition through your directions, but when i boot my lapto using Windows XP CD it copies the required files but when i press ENTER to install Windows XP the message appears that " Setup did not find any hard disk drives installed in your computer. Make sure any hard disk drives are powered on and properly connected to your computer and that any disk related hardware configuration is correct. This may involve running a manufacture supplied diagnostic or setup program. Setup cannot continue. To quit setup, press F3." Please note I have C: drive installed windows vista on it, i have drive D: files are available for recovery disk pre-installed by the windows vista or manufacturer. My lapto is Toshiba EQUIUM L40. Please advise how to install Windows XP on this computer.
Thanks wonde.
