I am a new Linux user. I am facing problem in booting my PC when I installed Ubuntu 20.4 along with Windows10 dual boot.
Now when I start my PC there is GNU Grub page opens with this message: Minimal BASH-like line editing supported.
I have already tried Boot-Repair through a live USB, but it did not opened the Boot-Repair option for my PC, therefore I couldn't my grub this way. I am also providing the Boot-Repair Boot Info Summary here for your reference.

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would not act on the MBR.
Additional repair would be performed: win-legacy-basic-fix
sudo efibootmgr -vwhich is also shown in report. But your p5 partition is not fully shown. I might try fsck or e2fsck on it. askubuntu.com/questions/642504/… If fsck works, then Boot-Repair or just changing boot order with efibootmgr may work.
