Question: the bootcamp partition disappeared
the bootcamp partition has disappeared, it will not find> tools> the boot disk, and will not even boot it after restart and manual switching.
On the 700GB I have a 700GB I do not need to save, but to combine to have a 2TB (fusion disk).
Thank you for any advice and help to remove the bootcamp section when it does not show it to me.
