    Replaced CMOS battery Lost Win 10


    I just replaced my CMOS battery. The system rebooted and all my Windows 10 files are gone, it's created a new drive N: but I couldn't restore from Command line and I have a semi useless Windows 8 in place. Help?

    :)

    Lost activation after cmos battery replaced

    Thanks Brenda - That would have been my last resort. However; decided to give Microsoft Support a try snd they resolved it for me, via remote ontrol.

    Hopefully; this type of problem is not a sign of things to come, following the upgrade. We should be able to maintain our machines without being put through this hassle. Thanks again!

    Lost activation after cmos battery replaced

    My computer required a cmos battery replacement, this morning.

    It is/was running Windows 10 (upgraded from Windows 7).

    Battery replaced.

    However - I am now told that Windows is not activated and I need to supply a key (which naturally I don't have, due to the upgrade).

    How do I overcome this - can't find an answer on Support?

    Help!!!!!!

    The only thing replacing the CMOS battery would do is change your boot settings to default in Bios. Without seeing a screenshot of disk management:

    My guess is that you have two hard drives. You installed Windows 10 on a second hard drive. When you replaced your CMOS battery, the boot settings went back to default, which was to boot from the Windows 8 hard drive. You need to go back into BIOS settings and change the boot order to boot from the Windows 10 hard drive.

  5. *Ditto Replacing the battery isn't going to erase anything. Like he said, your boot order got changed. If you have installed Windows 8 after the fact though, your files could now be truly gone. Depending on how and where you installed Windows 8.

    Thanks for your reply. My reason for replacing the CMOS battery was a system freeze, having scoured the Google world this appeared to be the remedy. I had installed a Crucial SSD. In the process of examining Disk Management I found that whilst the new Drive(Disk 0) had a System Reserved Partition, the next partition was indicated as the boot partition but did not recognise the SSD when I reset the boot order in BIOS.
    Since then I have done a Clean Install of Windows 10 from the original .iso disk. Now the system continually freezes and crashes. It's frustrating as I am trying to use Command (Admin) but I have been unable to complete any software changes because it never completes the download/installation sequence.

    It's an Asus mobo, I have manually checked, the RAM, (removed and reseated) the Graphics Card (Nvidia) and updated all Drivers.

  7. I think you need to post a screen shot of your expanded disk management screen, if possible. I'm not exactly understanding what you did and where your at now?

    Replaced CMOS battery Lost Win 10

    I tried to read the post 4 a few times .... it appears that Jonty45 has done a clean reinstall after his first post; and now he is experiencing system freezes and crashes. But my understanding might be incorrect.
    Hi @Jonty45. Are you experiencing application crashes, or random shutdowns or BSODs?
    If you want, you may post a log following the Blue Screen of Death (BSOD) Posting Instructions in your reply post. The files help to determine the root cause of crashes.

    Both, the BSOD's have been analysed by Whocrashed utility. Most refer to software issues with the kernel/software. The freeze\crashes are still occurring
