Caution: this rewrites the boot record and replaces the BCD store.

Assign the drive letter

Give the small FAT EFI volume a letter (v: here):

diskpart
sel disk 0
list vol
sel vol <FAT_~260 MB>
assign letter=v:
exit

Repair the boot record

cd /d v:\EFI\Microsoft\Boot\
bootrec /fixboot

Rebuild the BCD store

Rename the existing BCD, then rebuild for c:\Windows with locale en-us, system volume v:, firmware ALL:

ren BCD BCD.old
bcdboot c:\Windows /l en-us /s v: /f ALL
