Hope the title is good enough
Following Kari's excellent tutorial I successfully transferred my WIN 7 and Programs (they are on an OCZ SATA SSD) to a new motherboard and CPU. Until here no problem, the OS started perfectly, went online and activated my copy of Windows 7.
Then I shut down and connected my second HD, a small 320 GB Scorpio where I save all my personal files. Reboot and Windows 7 after loading, freezes. Had to reset and boot in save mode but no information about the problem. devices are OK, the disk is seen from the system with its correct letter but when I boot normally it still freezes the OS. As soon as I disconnect the SATA HD's cable, Windows 7 boot perfectly.
On UEFI Bios all the 6 SATA channels are enabled, I also tried to change connectors but the problem is still there. If additional details are needed, I will be very grateful for some help.
