Hi, a while back I had trouble with my GRUB, it simply said it lacked boot media. This was because when using Windows CMD: bootrec /FixMBR wiped it I must've wiped the boot record? I was sent this link Using livecd v17.0.1 (and above) as grub to boot OS with broken bootloader and this worked.
HOWEVER, I rebooted my laptop and this happened again... Now, I try that previous solution and it boots and once I type in config /boot/grub/grub.cfg it boots me straight into the GRUB that I'm MISSING so I know it exists!!! But the second step of the process includes installing the grub, which is where it fails. Here is the error I receive after downloading grub-vanilla...
##Grub Installation Error
michaelo@michael-pc ~> 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.
(If I could be a pain and ask for a small amount of hand holding through this process I'd really appreciate it as I need my laptop for work)
