I want to install my copy of Win7 on my new e series laptop instead of the original Win8, but am running into the Microsoft secure boot manager (says "invalid operating system" when attempting to boot from my Win7Pro cd). How do I get around this? I can't seem to get into BIOS or into the secure boot manager to change settings. Has Sony gone all Apple on us and restricted user flexibility?
Thanks a lot for you guidence. I have done my installation. But the thing is after installing Windows7 I cant get into BIOS to change the Boot Order.. Also the Assist & VAIO buttons also not functioning in Windows7. Please help me on this regard.
