I'm currently using a dual boot setup on my laptop, with Windows 10 and Fedora and I'm planning to replace my HDD with an SSD for obvious reasons.
I'll make a clean installation of both OS, but I've got a doubt regarding the EFI partition: since Windows creates a 100 mb big ESP by default (if I remember correctly) and that's not enough, I've read that the best way to have a bigger EFI partition is to create it before the installation of Windows 10.
Is that right? Or is there a better way to proceed?

Most likely, you won't need larger ESP (EFI System Partition). Windows OS loader is rather small and Fedora will most likely just install GRUB on ESP and place the rest of its boot files in
/boot
which will be on a separate partition anyway. Unless you're going to experiment with unusual Linux setups (like EFISTUB booting etc.), 100 MB should be sufficient.If you want to have a larger ESP just in case, you can create one using Windows installation media before the partitioning step.
How to manually create ESP using Windows installation media
Before the partitioning step:
(Technically, you could also do this on the partitioning step and click Refresh afterwards.)
diskpart
Enter. Diskpart will take a while to launch.list disk
Enter A list of disks will be printed. Note the number next to yours (most likely0
). Select that disk:select disk 0
Enter.create partition efi size=500
Enter (500
is partition size in MiB).exit
Enter.
