Get another computer and boot with live ubuntu and fix boot. Use google for more detailed instructions.

1- Go to bios
2- Deactivate Secure Boot
3- Boot your usb
4- Graphic install
5- Choose between partition or full Hard disk
6- You re ready to feel like mr robot


7- If grub doesnt launch pm me with your mail and i tell you how to fix it (i need your mail because i cant pm, im new in this forum)

Sorry that you lost your OS. Also sorry that you had to make a pointless thread to tell everyone.
Where's the question?
