I had dual OS running on my system (the default was Windows 10, then I installed Ubuntu alongside Windows). With the intention of deleting Windows and keeping only Ubuntu, I logged in to my Ubuntu (chose Ubuntu from GRUB), used Gparted, and deleted ALL the partitions, except the following:-

  • Partition containing linux installation
  • Partition for linux swap space
  • Other NTFS Partitions - containing my data.

So, basically I deleted the Windows C partition, system reserved partition, and EFI partition.
This caused my Ubuntu to not load.

As instructed in this answer, I used a bootable USB drive (Proteous LinuxPorteus Linux) and booted from it (in TRIAL mode).
Using Gparted, I created a new partition named "EFI System partition" setting its flag to boot, esp.

My partitions now look like this:- enter image description here Then I installed GRUB using this guide.

Notice that the name of my efi partition is not /boot/efi intead it is /dev/sda1.

Somehow, the GRUB menu has returned, as I see it when I boot my PC.
But, when I try to choose Linux from there, I get the following error:-

enter image description here

Even now, I can't seem to boot my Ubuntu.

What can I do to resolve the issue?
