Due to the issue with Windows 7 being too dark on the Ideapad S400 (backlight issue), I decided to roll back to windows 8. To install Windows 7 from our deployment server I changed the BIOS to Legacy Support., but then to install Windows 8 I changed the BIOS back to UEFI but now under FI (Boot) only the network card is listed and not the hard-drive. If I roll back to BIOS to legacy then the hard-drive is listed as a boot device. Sound like a bug.
I really got the feeling that the BIOS of the Ideapad S400 is a beta. Will Lenovo issue a BIOS update in the near future? This is the worse laptop I've even seen so far!

AFAIK, to see the HDD under UEFI boot on the BIOS, you must install Windows 8 in UEFI (HDD being formatted as GPT).
1. Install Windows 8 in UEFI as stated in this guide.
2. Boot into the BIOS, press F9 to reset BIOS to default then check if HDD is now listed under EFI boot
Hope this helps

Well now I can't even go in the BIOS anymore to change back to UEFI to install Windows 8. (F2 or Fn + F2). I put back the BIOS back to Legacy so i could install the USB stick with Win8 . The laptop boot straight to Windows 7 which i can't use since this laptop is not compatible with Win7 (dark screen issue).
Any idea? Sorry loosing it ..

Try to press the One Key Recovery button located at the left side of the unit then try and enter the BIOS Setup Utility.
