Hi
Im sure the answer is here somewhere but I can't find it.
For various reasons I would like to do a clean install of Big Sur. My problem is I have an active Boot Camp partition that works just fine.
Is there anyway I can do a fresh install of the Mac OS and relink to the existing Boot camp partition or can someone advise me of best practise to go forward, maybe clone the windows installation and reinstall?
My thanks in anticipation
Stephen
You need not enable Automatic Updates, if you can check manually. There may be a situation that you do not want latest updates which can cause issues. I will usually check for Security Updates, and leave OS updates.
A Fusion drive will make the Windows boot slower, but the macOS side should boot quickly. Are there specific applications that are slow. From macOS Terminal, can you post the output of
diskutil apfs list
and we can check if there are any issues. Another tool is https://etrecheck.com.

Is this what you want
Thanks a lot

Your Fusion drive looks normal. macOS is installed on the faster SSD, with the HDD as the backup store. Can you check MacOS Activity Monitor (Activity Monitor User Guide for Mac - Apple Support) and look for any issues?
Unless you want to erase the whole storage, just reinstalling Big Sur on Macintosh HD should suffice. If you erase the whole disk, you will need to also re-install Windows.
Is there a specific reason you want to re-install Big Sur? Be aware that there are known EFI issues with Big Sur and Windows.
Thank you for taking the time to help.
The windows 10 boot camp partition works brilliantly. all I use it for is some specialised Audio Editing software not available on apple platforms but it wont run under a virtual machine.
My mac has got unbelievably slow. What is the best way to start over so to speak? i wondered about deleting me as a user and creating a new one. Might that help?
Thank you

What is the year/model of your Mac (do not post the serial number)?
Big 11.0.1 is a much older version. See What's new in the updates for macOS Big Sur - Apple Support for reference.
Does your iMac have a Fusion drive?
Make sure you make a backup of all your data, Windows and MacOS partitions, before you do the install.
it says
iMac (Retina 5K, 27-inch, Late 2015)
11.0.1 (20B29 big sur
What I stress is that its definitely got slower over time
Thanks a lot
This is very helpful.
I wonder why am not being offered the updates or even see and option to install them.
Yes its a fusion drive
Thanks again
My fault, Automatically keep my mac up to date wasn't ticked.
Im downloading now!
