How to format whole disk with anaconda

[jawadalkassim]

Now i have both Fedora and Windows 10 dual boot at the same disk
i’m planning to re-install Fedora from Everything.iso as minimal install and remove windows
but there isn’t an *Erase Disk *option in Anaconda like Ubuntu installer or PopOS or whatever
Also i’ve noticed that by advanced partitioning when i delete partitions anaconda didn’t merge free spaces together

Fedora Docs > Installing Fedora > Installation Destination
If you selected automatic partitioning and the I would like to make additional space available , or if there is not enough free space on your selected hard drives to install Fedora, the Reclaim Space dialog will appear. This dialog lists all disk devices you have configured and all partitions on those devices. The bottom right corner of the dialog displays information about how much space the system needs for at least a minimal installation and how much space you have reclaimed.

Ok thanks,
Could I use I would like to make additional space available
with custom install or advanced partitions, or just if I choose automatically partitions also that means I can’t choose BTRFS right? Should I wait until fedora 33 becomes available and BTRFS is the default?

Yes, Btrfs should be the default in Fedora 33, which should be released pretty soon.
