If you boot to recovery environment it lists the win7 installation that it sees. Is it listing one with (C at the end? So windows is on partition that is called C? Last time it was E!! Are you booting from dvd or using F8?

It's called C instead of E because you marked that partition as active

7B means: windows thinks it's AHCI and BIOS thinks IDE. Or the other way around. Because windows loads AHCI it must be bios.

Did you change bios settings? For example "restore to safe defaults"?

1. Restart the computer.
2. Press the F2 key to enter the BIOS Setup Utility when the "Lenovo" logo appears on the screen. The BIOS Setup Utility menu will be displayed.
3. Set the SATA controller to "AHCI" mode. (The Interface will be different on each model. Most of them are under the "Advanced" menu or "Configuration" menu.)
4. Press the F10 key to save the new setup, and then select “Yes”.
5. Restart the computer.

So it was ahci already. Windows tries to start msahci as well. But it wasn't there!
What other SATA options do you have in bios? (AHCI, RAID,IDE?) give a summary please
