Hey Guys!
While fixing a lifebook i could not boot from usb with windows 7 on. So here is the fix :
To boot from USB or CD/DVD media, please change the BIOS settings:
press "F2" key to entering BIOS setup
go to "Security" Tab and "Set Supervisor Password"
after that go in the "Security" tab to "Secure Boot Options" and "Disabled" the "Secure Boot Option"
go to the "Advanced" tab then "Boot Configuration" and "Enabled" the "CSM"
Now you can remove the Supervisor password in the "Security" tab.
Finally, go to the "Exit" tab and use "Exit Saving Changes".
Your LIFEBOOK will be start now from every bootable CD/DVD or USB media.
Additional information:
Windows 8 Recovery media or USB sticks with Windows 8 Recovery boot Image is not affected!
