How to fit Windows into Grub?

Question

linux

I installed Windows then Ubuntu. Grub understood everything, and when turned on, it gave a choice.
But in ubuntu i removed the disk "Ripped by the system"-100mb
And after reboot only ubuntu works in Grub. Can it be fixed? and how?

Answer 1

There is a suspicion that you are missing these files. Until I slammed them, Windows did not disappear from grub.
1. Restore Windows boot
2. Either reinstall ubuntu or reinstall grub

Answer 2

1) Restore the Windows bootloader (it was on the partition you deleted, now you can put it on the same partition as Windows)
2) Restore GRUB

Answer 3

Restore GRUB
