The problem was actually the combination of 3 problems. I resolved them one by one after hours of researches and struggles.

First access the maintenance mode as root user.

Then run

1. nano /etc/default/grub
2. Replace the content of the line GRUP_CMDLINE_LINUX_DEFAULT by GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 iommu=soft"
3. Save and exit
4. In my case,there were few corrupt files in /dev/sda9. So I ran fsck /dev/sda9 and gave y to all queries.
5. Next Reboot using reboot command

If still you are unable to boot, then disable SECURE BOOT in BIOS setting and reboot again.

If still you are unable to open, then enter the recovery mode and look for the error and do research for your error.

EDIT: I posted this answer using my ubuntu OS that i troubleshot few hours ago.
