How do you go about with the dual boot Vista/xp installation when you get the message that disk is not recognized at xp install time and the BIOS does not have an option for you to deactivate native SATA?

Some excellent tutorials here for Dual booting vista and XP when vista is the first OS. Finally got round all the raid issues that come with my Laptop, ie no recognition of HD during XP set up. Fixed that with nlite and Intel Matrix storage, but now we get the fun issue! My vista recovery disc has no option to repair from boot!!!! So after I installed XP and then went to repair the boot sequence so the computer recognising Vista and XP in the boot menu, all I managed to do was completely format and install Vista! Why is everything so rubbish?

Any ideas what I could do (and don't say buy a new copy of Vista!)?

Oh, I have had that, it's a nightmare! You have to create a bootable image of XP in which certain drivers are contained! You need nlite (free download) to make the image and burn it to disk, and you need the drivers from Intel Matrix Storage ..... something... Copy the drivers from the intel program once installed into the drivers addition section in nlite, (which ones?) well I did em all and it worked for me!!! Others have had other troubles there!!!

Good luck.

nLite is a greate program, i use it often. The drivers do not "have" to be on the disc, they can be loaded during the initialization of the install process, from another disc.

Right you are indeed! But you need to have a floppy drive attached if you're using Vista (as you know, I've read your tutorials and you clearly know almost everything!

Maybe you can help me, I did everything you said, but my stupid recovery DVD doesn't allow to repair, format and reinstall only! (Total Rubbish eh?)

So guess what? I'm back to a single Vista! I will get my dual boot though, even if it kills me! Anyway, can I do the 'repairing' of the boot menu without using the DVD Vista install by using VistaBootloader or vistabootpro (something like that anyway)? What's your take on it?

I wasn't trying to be misleading earily by saying 'on a disc' I just understand that too many option often fries the brain!

ok, i installed xp into the partitioned hard drive, but now im stuck in it, my laptop came preinstalled with vista and i have no vista recovery disc, i downloaded the vista loader and installed it but when i choose to load vista or xp or system recovery it just loads xp, yes i checked to make sure the right drive was selected. any help please? sorry if im leaving out important information im new to this..

You need to boot XP (which happens auto) the download and install Vistabootpro. After that listen to this guy Install Windows XP in a Dual Boot with Pre-installed Windows Vista that's what I'm trying because I have a Vista recovery disc that can't repair! Only format install. It seems from the explanation that VistabootPRO can change the boot entries from the XP area. I hope I'm trying now!

i just got vista running but when i go into the boot menu and try to run xp it gives me a ntledr error, what do i do with this? am i screwed and do i just have to reinstall xp?



what i had done wrong in the vista boot pro is i had the wrong setting selected

I'm out of my depth here, have been all day. I suggest you copy that error and google it! Someone will have something useful to say on it. I'm sure you're not screwed though, just temporarily waylaid! I have heard of that error, can't say I know what it means. I'll google too and let's see what we get!

I googled and lots of people are talking about ntledr error, missing. Check them out....
