Windows 10: Windows 10 re-installation alongside Ubuntu after accidentally deleting it

I recently installed ubuntu linux from a usb flash drive. I did create a seperate partition for the installation of ubuntu, however the installation was performed on the ssd containing windows 10. When I reboot, I still have the windows 10 boot option in the choices, but it leads me to troubleshoot options. how can I reinstall windows 10 and which option should I go for?

Accidentally deleted "Windows" main file, can't boot Windows 10 and Ubuntu boots automatically.

Hi

I was trying to delete "windows.old" file located in main partition "C", but it seems that I've accidentally deleted the current windows main file "Windows", and after deleting finished, I was not able to
open any programs, error appears when I try to do.

I was installing Ubuntu alongside with Windows 10, I got some problems with Ubuntu also, so I reinstalled Ubuntu, but I got a new problem, that there's no boot menu to choose Windows 10 or Ubuntu, i.e: Ubuntu boot automatically.

I can see windows files through Ubuntu file manager, and I see "Windows" folder and I don't think that it has been deleted.

So, how can I retrieve Windows 10 again?

Thanks in advance
