Computer won't boot after CMOS battery change, Changed from AHCI to IDE and back with no results

I can't get this thing to boot to windows! It is giving me a registry error, it can't find System32, etc

What other settings can I modify in the bios to make it pick up the OS from the HDD? I really wish I had taken note of the settings before the reset, alas you live and learn (doh)

The machine is a HP Elite 6300(?, I'm not in front of it right now) WD 500 GB SATA drive. Let me know what other info you need to help and I'll get to it asap.

With an aftermarket Hiram Boot disc I can see that the registry is all there, and no files are missing,but I can't get it to boot from the HDD.

Please help a noob out!

It's probably the BIOS setting you changed.. not all error messages are interpreted correctly so you probably won't be able to fix anything from a Live CD. Go back into the BIOS and try different settings, checking after each time if the HDD is detected. You will have to try a disk controller setting (AHCI, IDE Native) and save the setting, restart the computer for the new setting to take effect, and check again in the BIOS for detected drives. Then try a different setting if necessary, save and reboot to check again.

If you installed SATA drivers, it may have to be set to AHCI with SATA enabled and if no drivers were installed, it likely to need the IDE Native setting with SATA disabled.

did you try the clr cmos jumpgates? Did you try another battery? The new one may (small chance ) be faulty and shorting out.

It recognizes the drive in the bios every time just won't boot to windows. How do I disable SATA?

Tried another one without change. This computer was fine, but I cleared the CMOS in a moment of stupidity and replaced the battery. Bios is accessible, I'm just not sure of the settings to play with other than IDE/ AHCI. After switching them and saving, will I need to shut it off with the power button or should the changes take effect when it tries to boot after saving?

If the BIOS lists the HDD every time, you don't have to disable SATA... up to what point does it get to when loading Windows????.. Even if it only starts loading Windows and quits, you may just have to do a Boot repair with the Windows disc.

As Chicano points out, if the master boot record has changed windows may not post.
A repair from instal disk may well get it up and running.BTW,did you try 'optimal defaults'
in bios setting? I know, i know. .

Can you boot into BIOS by tapping the delete key when boot up starts? If so, change the first boot device to HDD. Setting optimized defaults should take care of the problem. After you reset or update the BIOS, the first thing you should do is boot into BIOS and set it all up correctly, especially the memory timings & speed.

If your comp BIOS was in AHCI mode and it is now in IDE mode, this will cause major problems too. Set up the bios. Can try flashing the bios too if nothing else works.
