Boot problem when installing Ubuntu

[Suhail]

HI
I currently have Windows 10 and I wanted to have a dual OS with Ubuntu.
So I downloaded ISO file and made it into a bootable USB, went into BIOS and installed Ubuntu.

I chose the "install alongside WIn10" and filled in the rest of the details and the installation started.

It was all going fine until I got an error about boot not installed (something a long those lines). I also recall is mentioning something about grub.

Anyways, I hope someone can tell me what went wrong and why the installation got cancelled.

Thanks in advance, Suhail

Your EFI system partition is corrupt. You will need to repair it using either dosfsck or chkdsk/scandisk in windows.
