Cannot Update egrub - emman - 10-04-2018

Hi all.
I have recently been having issues with booting my PC. I have been getting this error:

Code:
error: unknown filesystem.

grub rescue>

I am able to boot the system by following the tutorial https://www.easytechguides.com/error-unknown-filesystem-grub-rescue.html.rub
However am not able to repair grub:

Code:
eman[member=7555]emman[/member]:~$ sudo grub-install /dev/sda

Installing for i386-pc platform.

grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.

grub-install: warning: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..

grub-install: error: will not proceed with blocklists.

Hep is apreciated.

Disk needs to be MBR, or you need a CSM partition so you can boot from the media channel. Are you dual booting with other Linux systems? Did you install a 32bit OS on a 64 bit machine? Normally LL installer would partition the disk to MBR.

I am dual booting with Windows 8. I had Ubuntu installed, then removed it and installed LL. My system is 64bit and I installed the 64bit version of Linux Lite. This problem only started when I booted to Windows from ll's grub screen.

Something to note:

The system always booted into Windows - I was never able to change this, so I always

on boot held ESC key
Choose Boot Options
Select LL Drive

before I can boot into LL.

I also Choose Something Else at the Installation Type screen during LL install, so I allocated my disk partition manually.
Could this be a cause?

If you were dual booting Windows 8 with Ubuntu (I'm guessing 16.04) you were most likely dual booting from a 32 bit EFI boot partition. LL does not have a provision for this, and requires an MBR partition to install grub to. There are some tutorials here on accomplishing an EFI dual boot which can effectively allow for LL to boot, but you will find yourself with continuing issues involving LL updates, that will often require some skill with Linux.
