I bought this new laptop and there are tons of problems in installing ubuntu. There is a not full solution here:
It doesn't work for me cause I ended up where I cannot do what the solution says. Let me start from the beginning.
I used a USB stick with the latest version (ubuntu-15.10-desktop-amd64.iso) and after many tries I could install ubuntu.
I don't know why but the loading screen and the passages through installation went through smoothly all of a sudden, till the really end when I had to reboot manually cause i couldn't move the mouse and click "Restart Now". What ever.. The installation left 500Gb to windows 10 and created a new partition of 500Gb for ubuntu. I tried to boot the new installed Ubuntu but nothing: black screen. I booted in recovery mode and I went to driver settings and I set nVidia ones instead of the wrong ones. So finally when I rebooted Ubuntu normally it worked. I installed some stuff and did full updates of the system then I shutted down ubuntu. After using Windows 10 a bit I booted again ubuntu it gave me the following error:
kernel panic-not syncing: VFS: unable to mount root fs on unknown block(0,0)
Ok then I looked it up and I found out I had to start ubuntu from liveUSB and run some commands like:
sudo mount /dev/sda1 /mnt sudo grub-install --root-directory=/mnt /dev/sda
The problem is I cannot anymore! liveUSB doesn't start as it get stucked in ubuntu loading screen! The laptop doesn't even have a cd reader I can only use USB! The recovery mode of ubuntu gives kernel problem as well. The BIOS setup is already changed to:
Secure Boot = [Disabled] Load Legacy Option Rom = [Disabled]
Also I tried in grub panel pressing 'e' to write
nomodeset at the end of linux line. I did it everywhere (installed grub panel and the liveUSB one) hoping that was allowing me to boot something but it never worked.
Please read the answer in the old thread to have a full picture.
How do I do what they say here if I have no access at all to the prompt?
Dual Boot on Dell Inspiron 7559 laptop
Should I go on Windows 10, delete ubuntu partition and start over?
