Rewrite the original /boot/efi esp partition and selected a previous pop os partition no formatting

So I have win 11 and pop os dual installed on the same drive. I switched between them from boot menu, but suddenly I couldn't find pop os in the menu, probably because of my corrupted USB flasg drive I removed without ejecting while it was getting scanned by a badblocks command. I tried to access my pop os partition from windows through a program, and my files were there but the /boot/efi folder was empty.So I'm trying to add a new bootloader in the ESP That was already there by trying to install new pop os, but without erasing my root partition. But I'm afraid to continue sinvlce the option says erase and install. Do you think I should continue?
