So yesterday I managed to install Linux, by adding the commands nomodeset and idle=nomwait to the grub. I'm still getting error messages, but at least I was able to enter the desktop (only in the same session as installation, everytime I reboot I get the frozen violet screen). (Trouble booting and installing Linux - Broken BIOS suspected?) My PC specs: (msi PE60 6QE, nvidia gtx960M,16GB DDR4,intel i7). I am currently running the 15.10 64-Bit version of Ubuntu. Now somehow after choosing to run Ubuntu from the grub menu upon rebooting, I get a violet, frozen screen.Frozen violet screen Sometimes when I don't add the commands "nomodeset" and "idle=nomwait", a black screen appears and from there nothing happens either. I have also tried starting Ubuntu in recovery mode, but it just freezes during the terminal is open, the last messages I get when running Recovery Mode are:

    BIOS EDD facility v.016 2004-Jun-25, 0 devices found
    EDD information not available

after these messages Recovery Mode freezes.

When I try to boot with generic I get the following lines before the screen freezes

    Booting command list

    Loading Linux 4.2.0-16-generic ...
    Loading initial ramdisk ...

and that's when it freezes in generic. same thing for generic (upstart). I'm just trying everything, nothing seems to work.

I'd be happy for every help.

  • When you boot from the LiveCD can you reach the desktop successfully ? – Scott Stensland Feb 20 '16 at 13:28
  • Hey, when using my USB stick to boot, so when I actually use my USB stick to "install" Ubuntu it works, just have to add the nomodeset and idle=nomwait in the grub. However after installation, when I want to reboot using the Hard Disk partition I assigned to Ubuntu during the installation process, my screen freezes in the purple screen, I don't see any logo whatsoever, hope this is what you're asking for. it could be, because of my drivers. if I install linux and upgrade the drivers in the same session without rebooting, are these changes saved for the next boot? – LST Feb 20 '16 at 13:39
  • So my problem actually is, that I can enter the Desktop to install Ubuntu, however when I reboot and try to access the Desktop the screen freezes after I choose to enter Ubuntu in the grub, basically I can only get in in the same session I install ubuntu. Reboot after install simply doesnt work and I can't enter ubuntu by using the partition on my Hard Drive dedicated to ubuntu. – LST Feb 20 '16 at 14:10
  • @LST. Nvidia drivers installed as i mentioned in the other thread? – Ashu Feb 20 '16 at 15:52
  • Yes, I managed to get in once, I take it was luck, pressed Ctrl+Alt+Del during the freeze, it rebooted and suddenly I managed to get into the desktop, updated the drivers as you told me but I get the same freeze when I reboot and Ctrl+Alt+Del doesn't seem to fix it anymore, guess it was just a lucky shot – LST Feb 20 '16 at 15:55

This is fixable. On boot after BIOS screen tap SHIFT key to reach the grub screen. up / down arrow to hightlight top OS release on list (newest one) and instead of hitting Enter press E to edit.

Use your arrow keys to move cursor to line which starts

linux /boot

put your additional kernel options at end of that line. This fix is only good for current boot. Do this to confirm its the fix U need. hit ctrl-X to proceed to finish current boot.

If above helps U reach the desktop, then to make above temp change permanent, one you reach desktop open a terminal window ctrl-alt-t and enter

gksudo gedit /etc/default/grub

or if you know vi 

sudo vi  /etc/default/grub

edit the line starting with

GRUB_CMDLINE_LINUX_DEFAULT

so it appears

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

do similar for additional kernel options. Save your file then in terminal issue

    sudo update-grub

Let us know how you get on

PS. On boot after BIOS tap left Shift key to bring up grub menu. Is this possible ? If so go into Recovery Mode on topmost OS then into graphics Failsafe mode. Possible ?

  • I did that, added nomodeset and idle=nomwait at the end of the linux /boot line(http://askubuntu.com/questions/736889/trouble-booting-and-installing-linux-broken-bios-suspected/736893?noredirect=1#comment1094469_736893). without these commands id be stuck with a frozen black screen, now instead it's a frozen violet screen. – LST Feb 20 '16 at 16:38
  • I managed to enter Recovery Mode without error, I could run failsafe graphic mode. If I choose to resume boot, the login screen pops up (finally!), however, when entering my password, the screen flashes and the login screen pops up again, it seems to be in a loop. When entering a wrong password, the circle next to the password field pops up and says the password is incorrect, quite normal. I also tried opening a terminal with Ctrl+Alt+F1 and entering my password and username there, but it says, that my login is invalid although I know it is correct, since I can see it in the login screen. – LST Feb 20 '16 at 21:42
  • The wrong password is probably a separate issue. – Scott Stensland Feb 20 '16 at 21:57
  • Guess I'm opening a new thread again -.- tried to rewrite my account as sudo using visudo doesn't work and I can't find anything about this issue. Thank you for your time! was a big help :) – LST Feb 20 '16 at 22:10

In my case the "fix" for this was to finally boot on the last known good kernel (second from the top not marked recovery), which did boot, but reported errors. I clicked through the pop-ups letting the system fix itself... Then I rebooted, selected the main OS, and it booted fine.
