Hi All, So I'm installing Win 7 Ultimate (6.1.7601.17514) on 3 exactly same laptops (Lenovo W541) with brand new disks. I installed Daz's Loader first then the recovery software. All machines activate successfully, however, one of them the F11 recovery doesn't function anymore during start menu (take me straight forward into Windows). That being said, once I uninstall the loader and reboot the F11 works again, strange. The rest of the 2 work just fine. In addition, somehow I have to disable Security Chip in BIOS for that specific machine in order to enter Windows. Otherwise it get stock in "starting Windows" forever. I'll be appreciated for any ideas.
