I have posted before about installing Ubuntu on my NP780Z5E-S01UB. I will give a quick recap of my previous problem below:
I installed Ubuntu 12.04 64 bit with really no problems on my laptop. I had it installed in UEFI mode with secure boot on. When I went to uninstall to install 13.04 I encountered my problem. Ubuntu was stuck on the boot menu in the UEFI settings. It was something like UEFI: ubuntu[...]. I could not get the entry off for anything. If I selected the entry, it went to a grub menu and said it couldn't start or something. I could boot into Windows 8 just fine, but the extra entry was annoying me. I had wiped my laptop and everything but still no dice. FINALLY after MONTHS of talking to customer support and googling, I got a BIOS updater tool which allowed me to reinstall my current BIOS version, which fixed the problem. Which brings me to my new concerns.
After dealing with that I learned that Ubuntu may brick certain samsung laptops with UEFI. I haven't found my exact model number on any of the numerous articles/forum posts I've read, but you never know. I read that it has only been known to affect 2012 samsung laptops. So now, I have a whole new batch of questions before I do ANYTHING with Ubuntu on my laptop, as I can not risk bricking this.
1. Is it possible to install Ubuntu in CSM/Legacy mode even though my Windows 8 was preinstalled in UEFI mode?
1.5. Would I have to switch UEFI mode ON if I wanted to boot back into windows IF I CAN install in CSM/legacy?
2. Could installing it in UEFI mode cause a brick if not possible?
3. Are there any precautions anyone knows of that I should know before attempting any Ubuntu installation?
4. Are there any more problems that have come to light about Samsung laptops and/or MY specific model?
