I got notebook with broken Windows booting and I have found some tricks how to repair it. I copied CMD from web and paste it to terminal. Imediately after pasting the CMD it executes with wrong disk. Then I tried to restart my computer and it says:

No boot signature in partition.

The CMD was:

sudo lilo -M /dev/sda mbr

Does anyone know how to repair it?

I would imagine you have an EFI disk and lilo acts like it's processing an MBR disk. But I only use grub so it's just a guess. As the answer below suggests you should run testdisk if lilo documentation makes no mention of backing up the MBR (Master Boot Record) before it runs. Note both MRB disks and EFI disks utilize a Master Boot Record. (Confusing I know).

I don't know much about boot stuff, but it sounds as if something has been overwritten. Try using testdisk. To do so, get a live CD or USB, boot into it, and in a terminal type:

sudo apt update
sudo apt install testdisk

and then run

sudo testdisk

and try this guide.
