Hi George,
What do you mean by <fedora installing the default (btrfs) "destroys"?
---
I have already installed fedora on a normal <desktop> by completely replacing  the HDD ..
In that case the HDD was initially presented with a single partition and fedora automatically created the partitions that were needed to store the operating system.
---
In this current case (the computer is a laptop)  I see that the HDD contains a partition (EFI System Partition) which perhaps should not be touched because it is used by the <BIOS> ...
---
this is the reason that I would like to know how to present (in terms of partitions) the HDD for fedora installation :
<basically I ask  if I have to leave some of the existing partition>

Thank you ..

Hi

upgrading fedora to version 35 I decided to install the OS completely from zero again, instead of doing the normal upgrade.


I have a laptop with two HDDs: / dev / sda (on which windows is installed) and / dev / sdb (on which fedora 33 was previously installed).


Of course I will install Fedora 35 on the ADD / dev / sdb .., but I would like to completely clean up the old installation by formatting the old data using gparted.


A fedora install using the defaults (btrfs) "destroys" the old data.  If you are looking for a method that would prevent recovery of sensitive data 
(e.g.), if the laptop is stolen and the sensitive information was not encrypted, there are "secure" erase tools..


I would like to ask for help about to choose the pertizioni to leave and those to format .. starting from the current situation that I transcribe below:
