BIOS settings not found

Here is my new question on askbuntu. "My friend installed Ubuntu 14.04 LTS on his Samsung NP 300 G5X laptop that had 4GB RAM and a 700GB HDD. He encrypted the Ubuntu installation and used LVM. After reboot he was taken directly to grub. He was successful in booting into Ubuntu a couple of times but then on entering passphrase he started getting this reply - 'fs type not found'. Now, he is stuck with this and cannot even boot from any live media for his BIOS settings is not appearing." Anybody out here to help???

Try powering off and hitting "F4" over and over during reboot.
I think F4 is the hard reset for Samsung.
He tried that too but that is taking him to grub. This time he tried advanced options. On entering passphrase the message was 'unknown fs type' instead of 'no fs type'.
*He accidently got into busy box of which both of us are unfamiliar. Is this of some help?

The brick problem seems to happen after installing GNU/Linux then writing to the EFI ROM.
"UEFI should garbage-collect after every reboot. Samsung's doesn't. The right thing to do is acknowledge the bug, fix it, and push updates to customers. The absolute wrong thing to do is blame the user for installing (GNU)Linux. But that's the easy and cheap way out, because the vast majority of people who trigger the bug will do so in this fashion."
I'm still looking for an answer. Many seem to believe that it's the EUFI, which will refuse to load when the EFI ROM data stored is > 50%. Samsung's doesn't clear as others do, but will allow it to build up if more than one OS is installed/used. This seems really stupid and really Samsung.
Many people indicate that they got their motherboard replaced after this happened to them. This might be just because most people are scared of hacking their own stuff and are easy to talk into paying $$$. Then again, you might be #^@&3!).
He took it to a Samsung service center. They said they shall change something in the BIOS.

Thank God! I'm so grateful because I could not find any answer to help you. It looks like once these laptops fail due to the EUFI problem that they are bricked for good.
What about removing all power from the machine, including the cmos
battery, and just let the machine sit overnight? That may not work now,
but I know that in the past, you could totally reset a machines bios
settings that way.

He did try that but they seem to work only in the past as you mentioned.
Thank you for being so concerned. Though I'm a newbie I have a suggestion. I heard that small distros like Puppy Linux can be installed on pen drives. Can we make Puppy Linux run on our system without accessing BIOS settings menu?

Without the BIOS the operating system would not be able to know how to use the various components on the motherboard. Based on how you worded your posts I'm not sure how much of the BIOS is working by the time it refuses to start the bootloader. It's worth a shot I guess.
Trisquel works as a live usb and protects freedom better than other distributions. I'd try that first. Good luck.
The BIOS works correctly. The problem is that he encrypted the whole installation but his passphrase is not accepted. Even I would have suggested Trisquel but without accessing BIOS settings menu how can he change boot device priority? I thought one could get away with that while using these small distros for they install into the USB flash drive but I was wrong. I had to configure BIOS to boot from USB even though it was not a live one but one that had the OS installed into.
*We will get more clarification from Samsung today. I'll let you know.
