Currently have windows 10 installed on my laptop (LENOVO G50-70, i5-4th gen, 6gb Ram and 1TB hdd).
I found out by trial and error that I can't have more than four "primary partitions" and so I played around with disk management in windows and got around 100gb of free space (Healthy, Primary partition).
SO now, I have the following partitions:
sda1 : System reserve sda2 : Windows C drive sda3 : Windows D drive free space (100GiB)
I also made a bootable pen drive with Ubuntu 16.04, and entered BIOS settings to change "boot" modes.
Unchecked legacy mode and set it to UEFI (which means UEFI is supported).
Enabled USB boot-up.
All fine till this stage.
Ubuntu installer opens up, I choose the 'select other option' and choose the unallocated free space, with file system ext4 and mount point as ' /'.
But in the middle of the installation, I get an error which goes:
grub-efi-amd64-signed failed to install into /target/ error
And my installation ceases and a report is sent to Developers
I looked around for solutions; found this:
NONE OF THE SOLUTIONS WORK.
1) I Have the laptop connected to the internet with secure boot disabled.
2) My file is already named with a '64' in the end
3) I don't know how to create another 200 MiB partition because the max I can have is 4 partitions
4) The same bootable pen drive worked for another laptop (Lenovo Ideapad) - so it's not a pendrive issue
I think, (basis of the hours of googling that I have done) that it has something to do with the fact that my memory/disc is MBR and not GPT (although I have no idea what does that mean, other than the fact that I can't create unlimited partitions)
