Getting Error PCI/VEN8086&DEV_1C26&SUBSYS_50061458&REV_05 (Acronis True Image Home 2012 Plus)

Hello!

I'm trying to move a complete Win7 Installation from an older computer to a newer one. The complete backup was successfull without any errors. But trying to recover the backup to the new computer, I'm getting the message "PCI/VEN8086&DEV_1C26&SUBSYS_50061458&REV_05" wasn't found. Sometimes I'm getting the error message ""PCI/VEN8086&DEV_1C2D&SUBSYS_50061458&REV_05"

What I've tried until now (The backup is on an external USB HDD):
Of course, I told Acronis to use "Universal Restore" with the location of the driver files.

I copied all drivers from the DVD of the new motherboard to the root directory of the external USB HDD. => Didn't work

I searched for drivers on the Internet and copied them also to the root directory of the USB HDD => Didn't work

I installed Win7 and than the complete chipset drivers. After reboot, I copied the content of the folders "WINDOWS/inf" and "WINDOWS/SYSTEM32/drivers" of the Win7 installation to the root directory of the USB HDD => Didn't work.

Put the old HDD into the new case and tried to clone it to the new HDD. => Didn't work.

Win7 is only showing the start screen and after a few seconds my computer is rebooting. Try the system-startup-fix from Win7 didn't help.

Do you have any ideas??
