what's the correct BIOS settings to fresh-install Win 7 on? Also, should I use GPT or MBR partition? Here are some pics of my BIOS:
On the first one, at the SATA Controller Mode, should I use Compatible or AHCI?
The Notebook is a Lenovo G500.

Definitely AHCI
Windows 7 32 bit won't support GPT, or EFI/UEFI
Ideally GPT is your is the newer and better choice.
Booting with GPT is only supported for 64 bit editions on EFI/UEFI-based system.
Windows should detect and handle EFI, but you need the 64 bit version of windows.
Windows 7 Should automatically load EFi/UEFI automatically if support is detected.
If doesn't.
- Back up all data to another drive.
- Boot the windows 7 installer
- Shift F8 should get you a command prompt
- diskpart
- select disk 0
- clean (all partition and data on said disk are lost)
- convert GPT
- exit
- Continue with the installer normally.
