Installation of Silverblue Rawhide (20201221.n.0.iso) removed Windows boot entry

My Dell Vostro 3350 have Fedora 33 and Windows 10 dualboot working normally.

Then I installed Fedora 33 Silverblue, by removing all Fedora 33 partitions in the installer.

At this point, Windows and Fedora33 SB still dual-boot correctly.

Then I installed SB Rawhide 20201221. Also in the installer to remove all Fedora 33 SB partitions.

After this, Windows is not being listed as available to boot (actually, the usual grub2 menu do not show up at all.)

How can I have the grub2 menu back?
