|I'm assuming you're booting the computer from the Windows 7 (or Vista) DVD.|
You get the Stop:00x000000CA error when the mboard's bios Setup has the mboard's SATA controllers in SATA or AHCI mode, AND the Windows DVD does not have suitable SATA controller drivers available for your specific main chipset on the mboard.
(Apparently, the Vista and Windows 7 DVDs have SOME SATA controller drivers, but not all possible SATA controller drivers, on the DVDs. Windows XP and 2000 CDs have NO SATA controller drivers on the CDs. )
You can fix the problem by either.....
- changing the SATA controller mode in the bios Setup to an IDE compatible mode of some sort, Save bios settings.
The Windows DVD will then detect SATA controllers and SATA drives as IDE compatible controllers and drives, you'll be able to complete Setup successfully, and later on after Setup has finished, you load the drivers for the mboard including the SATA controller drivers, then you can change the bios settings so the SATA controllers are in SATA or AHCI mode again,
- or - by leaving the bios settings set so the SATA controllers are in SATA or AHCI mode, and pressing a key near the beginning of loading files from the DVD when you see the line "Press (a key) to install drivers for.." or similar , then providing the SATA controller drivers for the mboard when prompted to do so that have been copied onto a suitable media source e.g. a USB flash drive.
If you have a generic desktop computer,
- the manual for the mboard, the printed one if it has it, or the one on the CD or DVD that came with it, and/or the manual for the specific downloads for tjhe mboard model on the manufacturer's web site, usually has detailed info about the settings in the bios Setup.
If you can't figure out how to set the SATA controller mode to an IDE compatible mode even when you do have that info, see the generic info below, or TELL US the make and model of your mboard - if you don't know that, the model is usually printed in obvious larger characters on the surface of the mboard, often between the slots, include any Rev or Ver number you see beside that, or it may be displayed on a logo (graphical) screen while booting the computer, but that may not be as specific as what's printed on the mboard surface.
- the CD or DVD that came with the retail mboard model has the suitable SATA controller drivers to be provided to Windows while loading it from the DVD. The mboard manual may have specific info about how you load the SATA controller drivers for the mboard while installing an operating system.
If you have a brand name system computer,
- usually we CANNOT find specific info about what you see in a brand name system bios version, but whatever the SATA controller mode setting is, it's presently set to SATA or AHCI, it's changable, and at least one other choice is an IDE compatible mode of some sort.
- the suitable SATA controller drivers download to be provided to Windows while loading it from the DVD is usually in the downloads for your specific model. If not, it's available on the web site of the maker of the mboard's main chipset.
NOTE that I've found that most retail mboard models of newer mboards have the SATA controller mode already set to an IDE compatible mode in the bios Setup when you get the new mboard, and that's the default setting, so that you don't need to provide the SATA controller drivers while loading files from the Windows CDs or DVDs.
