My desktop runs 5 disks and I've renamed disks in Bios advanced settings...

So now booting goes haywire and I have to select the proper disk manually with f11 on every restart, played with boot order etc...just a headache...

So basically, I updated my CMOS to current version last month, will taking out the battery and putting it back in take me back to old cmos version?

I just want to reset the MOBO to default, but without loosing my CMOS update.

Is this possible?

You are confusing the terms CMOS and BIOS. You updated your BIOS which is firmware that starts up your hardware. Cmos is just the memory that remembers settings that you set in the BIOS. If your issue is with messed up settings in the BIOS then resetting the cmos, either by a jumper or button (depending on your mobo) or by removing the battery, draining the system and sorting the jumpers will put your system back in default settings using your CURRENT Bios.

I'm still confused!

My boot sequence is screwed up....

My BIOS was 1.1 orginally, my new bios is now 3.20

If I take out the battery, will the bios revert to 1.1 ?

And is this my best solution for PC to reboot on proper disks?

I renamed them in advanced settings, wasn't sure to choose boot manager or the SSD ect...I want the PC to pick correct disk automatically as usual ;)

Your BIOS will stay at its current version which you mentioned is 3.20
I can't answer if this will fix your issue as I am unsure what you have done and I don't have access to a "proper" system (work pc atm) to double check BIOS settings to help guide you through it.

Figured it out, had to go into f11 advanced settings in and go delete the disk I created. I thought the function was rename existing disk, but actually this is the behaviour it displayed:

- Pick a disk (Disk 1)
- Rename it so something I could understand

Result:

- System tried to book from non existing disk I created!
