Re: reinstalling fedora 35

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:

			Partition

			Name

			File System

			Mount Point

			Size

			Used

			Unused

			Flags

			/dev/sdb1

			EFI System Partition

			Fat 32

			/boot/efi

			600.00
			MiB

			21.58 Mib

			578 MiB

			Boot,esp

			/dev/sdb2

			ext4

			/boot

			1.00 GiB

			295.10 MiB

			728 MiB

			/dev/sdb3

			lvm2 pv

			fedora_localhost-live

			929.93 GiB

			929.93 GiB

			0.00 GiB

			lvm
