Installing an image from a PC with ide drivers to a PC with (only) ahci drivers available

To save time with installing several programms an image was made form an old PC. That PC was using ide drivers for the harddrive. The problem was, that on the new machine, only ahci mode was available in BIOS, so that there was no possibility to boot. In normal cases you would change the entry in the registry before changing the BIOS Settings from ide to ahci.

Changing the registry entry remotely in commandline

Because there is no possibility to boot the PC with mismatching drivers, the registry entry had to be adjusted. There are several ways to get to a commandline, like Windows PE or simply with the Windows recovery DVD. Once the commandline is open, the registry editor can be started with regedit.exe.
Now the SYSTEM structure from the affected pc has to be loaded with File/load structure.

The structures are located at X:\\Windows\System32\config

Change following START keys:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci --> "0"
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\pciide --> "3"
