I was trying to install Atomic Wallet, when my Ubuntu froze up for over 2 hours. I forced shut down from hardware, and now Windows doesn't load up in the grub menu. These are the things I've done.

Code:
sudo update-grub
From here, I tried to list the menulists from grub.

Code:
awk -F\' '/menuentry / {print $2}' /boot/grub/grub.cfg
But I just saw Ubuntu.


Code:
