Do I have to do this on the new Mac (thus the USB-boot) or on my current macbook air 7.2 which I used to create the USB-boot?

Now I have a start-up issue, I have a "Real-Time Clock (RTC) Power loss (005) error" when booting. Also I still need the USB to start-up after using multibeast.

Does the any body had the same issue with a G2 series?
I used the latest Bios version from 02.47 Rev.A. I Changed the battery but the issue still remains.

This is a problem with this exact model (HP 800 G2). I don't have this problem with my other 2 mini PCs, Lenovo ThinkCentre m93p or m910q. Or any other hackintosh builds. It have not heard of this problem with e.g. the HP 800 G3 or G4 versions. Take a look at this post . The problem is OS X and the mobo uses different time settings. This is not a logic board error like HP told me. I changed the CMOS battery (which in fact was bad) but it did not fix the error. If I boot several times in Windows the error goes away. Booting in OS X I get the error on the next boot. Not sure how much effort I will use to fix this as it is mostlu only annoying. I did the Windows regedit hack but the error is back now. I am using OpenCore 0.5.9 as bootloader.
