Despite reading several askubuntu blogs related to this issue, I have been struggling for last 24 hours to solve this.
My current OS is windows 10 which has an EFI partition. I have a bootable USB from which I'm trying to install ubuntu 18.0.4
PC specification : 1TB HDD (100 GB unoccupied space) 256 SSD (80 GB Unoccupied space) Aim : Installing ubuntu with '/' under SSD. '/home' under HDD.
In the drive selection screen of Ubuntu installation, /dev/sda appears as HDD and /dev/sdb appears as SSD.
Installation fails with..
Unable to install GRUB in /dev/sda
Executing `grub-install /dev/sda` failed.
This is a fatal error.
This link talks about the same issue. But i'm unable to open a terminal while the installation is running.
I tried using the "Try Ubuntu" option and then proceeding to installation. Here i get the terminal. But then none of the commands as mentioned in this Question works on this terminal.
Also if i agree to proceed "continue without a bootloader" I'm completely out of reach of Ubuntu after the restart. There is no trace of it. In the BIOS setup, Bootsequence or anywhere.
Please help.
Disk set up:
/
and/home
should go). There should also be a place to select the device that has your bootloader. This should be the same device where you have the EFI partition for both OS.
