Problems upgrading dual boot system

After having upgraded my desktop pc from FC31 to FC33 without any problem I attempted the upgrade of my laptop HP Pavilion G7 from FC32 to FC33, had a conflict in kde/plasma that seems to be solved by now, but as it was not then, I tried a fresh install and discovered that it was required to reformat the sda2 /boot/efi to enable to proceed as I got the explanation that the partition is on ntfs format. I tried the same on my desktop pc and there there was no such constraint. I did not want to reformat the EFI partition knowing that it were to destroy the windows boot. So I ended up in installing, without any complication, FC28, of which I still got a live-dvd and from there upgraded without any problem to fc33.
There are other discussions that show that after FC29 there was a change in the installer that make it very difficult to do a fresh install with personal partitioning to older pc’s that do not have the right level of UEFI bios, it seems that at HP the level should be at least be 30 while my laptop is at 25, and there is no upgrade. The consequence is that I can only boot into Fedora by pressing ESC and/or F9 at the right moment at power-on.

You should have waited a few days or enabled the updates-testing repository when updating/upgrading

the efi partition should be FAT32, not NTFS. At this early stage of boot, I think Linux/Grub don’t even understand NTFS filesystem

that sounds hard to believe, could you link additional information?

Can you show us the outputs of

lsblk

fdisk -l

efibootmgr -v

My reply by email, though using the appropriate address, did not work, so here in the alternative way:

I found the bug report describing the problem and giving a dnf command adding a specific updates/testing >repository but it did not solve the issue

As releases before fc30 don’t complain, and Windows 10 neither, I don’t see why sda2 could be ntfs

Not asked for but additional proof that sda2 is not ntfs I made a screenprint of yhe partitionmanager output.
That the early implementation of UEFI on a range of HP laptops gives dual boot problems is also seen in discussions of other linux distributions, I found several at Ubuntu.
