Unable to boot OS - No boot device found. Press any key to reboot machine

Question

I tried to install Ubuntu 18.04 LTS in my laptop. Even though the installer ran without errors, I failed to boot. I tried it 8 times, both in Legacy and UEFI mode. Still nothing. It shows only: No boot device found. Press any key to reboot machine.

Update: I have identified the problem. Outdated microcode of my CPU was causing the problem. Reinstalled Windows and applied the update. Previous version: 20090330 Update version: 20180425

Could you please provide more details? Did you install it on a fresh hard drive, did you make all the necessary partitions? What do you mean "failed to boot", what happens when you try to boot? — SakoDaemon, Jun 22 '18 at 15:40
My laptop says "No boot device found. Press any key to reboot machine" — Mashrafe Aiman, Jun 22 '18 at 15:42
And no, it's not a fresh HDD and yes I created all necessary partitions — Mashrafe Aiman, Jun 22 '18 at 15:43
@MashrafeAiman Please [edit] the question to add details, including what you already mentioned, plus your laptop model, since the solution to this issue seems to be hardware/firmware specific. — wjandrea, Jun 22 '18 at 15:45
Try using whatever bootable device you used to install the OS, and tell us what shows up. (You may want to edit your questions with these details) — SakoDaemon, Jun 22 '18 at 15:46
@Mashrafe Aiman.. After Succeful installation when you restarted "no boot device found" at this point change your boot mode to opposite of what it is showing.. BIOS>UEFI & UEFI>BIOS — PRATAP, Jun 22 '18 at 15:47
Making the same mistake eight times does not fix the mistake. See How do I install Ubuntu?. — user535733, Jun 22 '18 at 16:01
@MashrafeAiman could you answer your question with details of how you fixed the problem? — Hee Jin, Jun 22 '18 at 17:08

Outdated microcode of CPU was causing the problem. Reinstalled Windows and applied the update. Previous version: 20090330 Update version: 20180425.
