How to Upgrade Motherboard or Reckoner and Go along the Current Windows Installation & Installed Programs.

To keep and use your current Windows installation, programs and settings later on changing your Motherboard or after upgrading your estimator (e.g. from your old Desktop to your new laptop), you have only to "tell" Windows to use the Standard SATA difficult disk controller driver at Windows kicking. To accomplish this job you lot must modify the registry according your situation (scenario).

Scenario 1: You haven't replace the motherboard nonetheless (in social club to upgrade your calculator) and your computer starts (boot) normally to Windows. In this case you lot accept to alter the registry from the current working Windows environment before proceeding to figurer upgrade.

Scenario 2: Windows fails to boot because:

1. You lot have already supervene upon the motherboard, OR  because
2. You take modify the SATA fashion setting from BIOS.

In this case you lot have to use an Offline Registry Editor to modify registry settings.

Scenario i: Modify Registry before you supervene upon (upgrade) the mainboard on your calculator (Windows starts normally).

– Use these instructions only if you oasis't replace your motherboard yet and Windows starts normally . If you have already supervene upon the motherboard and/or Windows cannot boot, then follow the instructions in Scenario 2. –

HKEY_LOCAL_MACHINE\System\CurrentControlSet\services\msahci

* Note: If you lot have Window 8, Windows 10& Server 2012,so navigate to the "StorAHCI" key
(e.g. : "HKEY_LOCAL_MACHINE\Repair\ControlSet001\services\storahci"), considering in these Operating Systems the MSAHCI has been replaced past StorAHCI.

three. At the right pane double click at 'Beginning' DWORD value and modify its value data to 0 (zero). Click OK when finish.

four. Now perform the same modification to this central:

HKEY_LOCAL_MACHINE\Arrangement\CurrentControlSet\services\pciide

5. If you apply RAID  (otherwise ignore this step) then y'all accept to perform the aforementioned modification to this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStorV

vi. Close Registry editor.

That'due south it! At present you 're ready to continue with your figurer upgrade. When done, enter y'all BIOS settings and specify the SATA mode (IDE-ATA, AHCI or RAID) according your needs or get out the default setting. Exit BIOS settings and start Windows. Windows should start without bug. and install the required hard disk controller drivers. When Windows finishes the driver installation, continue to install the balance device drivers for your new motherboard..

7. Highlight the HKEY_LOCAL_MACHINE key.

viii. From File carte select Load Hive (to load the offline registry).

9. Navigate to the disk where Windows installed on (eastward.yard. "C:").

ten. Open up the organisation file institute in "% Windir%\system32\config\" directory. (east.g. "C:\Windows\system32\config\system")

11. Type a Key Name for the offline registry (e.g. "Offline") and press OK.

12. Double-click to expand the HKEY_LOCAL_MACHINE fundamental and you should a new central nether it, named with the name you typed before (e.grand. 'Offline" in this example).

13. Aggrandize this new fundamental & navigate (from the left pane) to this subkey:

xiv. At the right pane double click at Start (DWORD) and change its value data to 0 (zero). Click OK when finish.

15. Perform the same modification to this subkey:

HKEY_LOCAL_MACHINE\Offline\ControlSet001\services\pciide

16. If you use RAID (otherwise ignore this step) you have to perform the same modification to this key:

HKEY_LOCAL_MACHINE\Offline\ControlSet001\services\iaStorV

17. When y'all terminate with the modifications, highlight the key you created earlier (e.k. "Offline") and from the File menu choose Unload Hive to write back the changes y'all made to the offline Registry.

18. Close the Registry editor, the Command prompt window and Restart your reckoner.

nineteen. Enter BIOS settings  and specify the SATA fashion (IDE-ATA, AHCI or RAID) according your needs or leave the default settings.

20. Leave BIOS settings, remove the Windows Installation DVD from the CD/DVD drive and allow Windows to start normally.

Windows should start without issues and and so will install the required hard disk controller drivers.

That'due south it!
