Windows 7: I Mistakenly Deleted A Partition With OS

I Mistakenly Deleted A Partition With OS

I have two partitions with different OS on them, Wondows 10 and Windows 7. I wanted to remove the windows 10 OS and merge the partition with that of windows 7, but I was unable to format the partition. So i used a flash that windows 7 as been integrated on it and I boot from the flash. When I got to the point to choose the partition I want to install on, i then formatted the windows 10 partition, leaving the windows 7 partition, then i exited the installation and restarted the system, hoping that it will boot from Windows 7 partition. But when it restarted, it's telling me that OS is not found. I checked the partition with windows 7 and it still as its files in it, but i can't seem to boot from it. Please what can i do, I really need to boot into the other partition.
