I had sata off in my bios, installed windows 7 rc no problem. Now if I turn on sata in my bios, windows 7 won't boot. Any ideas on how to make it boot with sata on? thanks

If you accidentally installed Windows 7 with SATA turned off in your BIOS, and now you're facing issues where Windows won't boot when you turn SATA back on, there are a few steps you can try to resolve this issue:

1. Switch SATA Mode in BIOS: Try changing the SATA mode in BIOS. If it was set to IDE mode before and you installed Windows 7 in that mode, and now you've switched it to AHCI or RAID, Windows might not boot. You can try changing it back to the mode it was originally installed in.
2. Repair Windows Startup: You can try to repair the Windows startup to address any issues that might be preventing Windows from booting with SATA turned on. Here's how you can do it:
   • Insert your Windows 7 installation disc or USB.
   • Boot from the installation media.
   • Select "Repair Your Computer" > "Startup Repair" and follow the instructions.
   []Driver Installation: Sometimes, changing the SATA mode requires installing SATA drivers specific to your motherboard. If Windows is unable to recognize the SATA controller in the new mode, installing the appropriate drivers might help. []Registry Modifications: If changing the SATA mode doesn't resolve the issue, you can try modifying the Windows registry. Here's how you can do it:
   • Boot into Safe Mode.
   • Press Windows key + R, type regedit, and hit Enter.
   • Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msahci.
   • In the right pane, double-click on Start and change the value data to 0 (zero).
   • Restart your system and check if Windows boots with SATA on.
3. Check for Windows Updates: Ensure that your Windows 7 installation is up to date with the latest updates. Sometimes, updates can address compatibility issues with different hardware configurations. If none of these steps resolve the issue, you might need to re-install Windows 7 with the SATA mode you intend to use from the BIOS settings. Remember to back up any important data before making significant changes to ensure no data loss occurs.
