Hi
I have an Inspiron 15z 5523 15z laptop. I upgraded to W10 in December 2015 by doing a clean install. Everything was working fine.
To cut a long story short, something went wrong recently after I did a registry clean using CCleaner (which I’ve done before with no issues) which eventually ended up with me being unable to boot in to Windows at all – I just got BSOD and/or error messages.
So, having backups of my files, I did a new clean install of W10. At the point of installation I wasn’t allowed to install on the C: drive (I don’t know why), so I put the OS on a different partition. I now have the C: drive (Local Disk) with Program Files etc. while drive D: is called OS. On both drives there appear to be some duplication of files and folders, particularly in 'Windows' - see attached.
Now when I restart the PC it asks whether it should start using W10 on Volume 3 or Volume 4. I can’t see any reference to these volume numbers anywhere, including in Disk Management. Volume 4, being the newer, seems to work and so is presumably the D: drive. Volume 3 won't boot to Windows at all - just tries a disc repair.
How can I delete from this Volume 3 to remove the apparent previous version of W10 to both stop the option appearing and free up space?
Thanks
