Deleted from the windows bootloader, how to restore?

Question

BIOS

Hi all.
today it became necessary to run one program that patches the kernel to antidetect the signature of one file.
there was windows 10, there was no other OS, I started the program and tried to patch the current windows 10, it didn’t work out, it turned out that the patcher (keepatch2) only works on windows 8 / windows 7, I
had to install another Windows on top, windows 8.1, which I am on now and I'm sitting, the program worked, I patched what I needed. running the keepatch2 program again, I saw that somehow in the list of two operating systems, namely windows 10, it was also patched, it was written:
windows 10 patched
windows 8.1
windows 8.1 patched
then I poked and pointed at windows 10, then pressed delete to remove the patch, because there was no need when I already did everything on 8-ke.
deleted, then rebooted, I look after the reboot, there is no windows 10 to select the OS boot, but only windows 8.1 and windows 8.1 patched.
Actually, here is such a problem, how can I restore it and so that I can choose windows 10 again, fortunately the files remained, everything, it seems. here:

a description of the situations in the picture (for clarity):

actually how to put windows 10 back in "Downloads" so that you can choose and how to use it before? after all, the files remained .. I ask for help, I really need my main working Windows, thank you all in advance for your attention.
