How to start system from grub2 console?

Question

linux

An error occurred during the installation of linux deepin (I wanted to format the partition with fedora and install the system there).
After it, the laptop rebooted and displays the grub2 console. How can I run fedora or win10 with it? Or fix the bootloader.
Output of ls command:

(lvm/fedora-root) (lvm/fedora-home) (lvm/fedora-swap) 
(hd0) (hd0, gpt7) (hd0, gpt6) ... (hd0, gpt1) 
(hd1) (hd1, gpt7) ... (hd1, gpt1)

Answer 1

I found 2 solutions:
1) If you know the disk and partition with the system, then you can follow this instruction
2) Use the fwsetup command to call bios / uefi
ps: To view help, you need to set the pager environment variable to 1.
set pager=1

Answer 2

The bootloader is not installed. You should boot from the installation disk and repeat the installation (or install only the bootloader if everything else is already there).
