I am facing booting problem after installing Ubuntu 18.04 LTS into my system using manual partitioning (in the Something else section).
Here, note down as details: I was going to install Ubuntu 18.04 LTS as a separate OS, (one OS in full hard-disk, did not along with any other OS like windows or any) and created partitions shown in this screenshot:
There is no any issue in installing OS, it installs with any kind of warning & errors. However, when I restart the system, it comes with a black screen with the message:
Reboot and Select proper Boot device
or Insert Boot media in selected boot devices and press a key
I already tried Grub-Repair command from the live session (Try now) Ubuntu 18.04 from USB. Still, it was useless to me.
I tried these commands
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
All things going good, but when restarted, then the same issue. Even I also tried in advance user too. It gives a report that successfully repaired restart when rested then the same issue come.
So give me the proper guideline for installing Ubuntu 18.04 LTS using manual partitioning One OS in full hard-disk.
Note:
- I already try to Erase the disk and install (first one) then it works fine. But I am interested in Something else (manual partitioning) section.
- Even I also try it along with Windows OS, then it works fine.
- I also try my partition (as shown in the first image) patent in downgrade Ubuntu like 14.04 & 16.04 LTS as Something else section still all things going great. But when try 18.04 LTS then only it comes with boot device not found issue.
- I also try it in MBR & GPT partitions tables, still worthless.
- I also try to create 500 MB Reserved boot partitions, instead of EFI partitions still helpless, even also helpless in /boot partition.
- I also try different options by selecting different drive partitions in device for bootloader installing section still, worthless.
