Hello Tomislav. What operating system are you using? I assume windows 7 but I just want to be sure.

Also, was it beta bios or a non-beta bios?

Is it wrong if my previous bios version was like 200ish from 2013 and i just update to this one?
 
Its probably reset the BIOS settings. Go into it and reconfigure the settings

You cant change from IDE to AHCI it'll crash.

If you want AHCI, you should put it on AHCI before you install Windows, not after

And since you removed the battery, you'll have to reconfigure the BIOS settings

You can just flash the latest BIOS. No need to flash every single BIOS
