Windows 7: MissingOsLoader after updates on IDE drive

MissingOsLoader after updates on IDE drive

I'm experiencing Windows 7 boot failure.
I installed Windows 7 x64 SP1 with proper motherboard drivers. I run windows update. after rebooting the machine, Windows 7 is no longer bootable.
I tried it many times: after updates, something breaks the bootloader.

CPU: Intel E8400
Motherboard: ASUS P5Q with Marvell SATA/IDE Chipset.
HDD: 80GB IDE Maxtor.
I'm using this IDE Drive for windows 7, it is in good health.
I think that the problem is generated by using such IDE chipset on windows 7 for bootloader and OS.

Detailed Step-by-Step actions perfomed:
1. Boot from Windows 7 x64 DVD
2. Prepare HDD: erased previous partitions; created system partition (100MB) + OS partition.
3. Windows 7 Installation
4. Activation + Home Group logging (I've other machines on the LAN).
5. Driver installation (marvell sata + intel chipset + nvidia vga drivers)
6. Windows Update: only important updates selected
7. Reboot
8. Windows 7 doesn't boot correctly.
Start-up recovery is called in (auto). It didn't solve the problem.
Clicking on "Problem details" I can read: MissingOsLoader

I tried to use bootrec (How to use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows) but rebuilding bcd get me to winloader.exe missing or corrupted.

There's a way to debug which update is the cause for reporting?
How to recover the system? I have no data to save on the pc but I would like to use a updated windows 7
Using my brother's SATA drive the are no problems.
