Question i accidently deleted efi partition on windows 7

[Dr. Tam]

hello i have dell optiplex 9020 (that i edited the bios on and made it boot off nvme windows 10 and boot from ssd on win7) i was trying to delete an mechanical hard drive partition and accidently deleted the 100mb windows 7 partition on my ssd. and now the ssd with my windows 7 is not booting, i also bought a windows 7 ultimate key online and i think its an oem key i wanted to know if its possible to reuse it on the same pc after in case my windows 7 ssd is doomed? i wanted to know if its possible to rebuild this 100mb efi partition or do i need to reinstall the windows?
