I tried to reinstall Ubuntu 16.04 alongside Windows 10 in UEFI mode. An earlier non-accessible version of Ubuntu 16.04 (due to a grub issue) was installed in legacy mode over which I am trying to reinstall Ubuntu 16.04 using a live USB, but in UEFI mode now.

As soon as the reinstallation (in previously installed Ubuntu's partition only) was completed, after restarting Ubuntu 16.04 a black screen with the following message was displayed.

[    7.958699] Couldn't get size: 0x800000000000000e
[   10.239669] sd 2:0:0:0: [sdb] No Caching mode page found
[   10.239699] sd 2:0:0:0: [sdb] Assuming drive cache: write through

How can I fix it and dual boot Ubuntu 16.04 successfully?

  • Possible duplicate of My computer boots to a black screen, what options do I have to fix it? Basically you have Nvidia Graphics (I know from your other question) so you need nomodeset until the Nvidia drivers are installed. The error/warning messages have nothing to with the GUI not coming up. –  Nov 08 '18 at 18:24
  • It looks like that there's no caching mechanism for your hard drive. It's disabled or maybe not recognized for some reason, so the system will write directly to the drive. – karel Nov 08 '18 at 18:52

    Hi @GabrielaGarcia , i don't actually have Nvidia Graphics card in my machine so why would i need those drivers ? Umm do you have any other possible solution to my problem ? – Ashish Bhardwaj Nov 09 '18 at 05:46
  • @karel thanks for the edit of my question . And i don't think https://askubuntu.com/questions/1085807/black-screen-after-installation-of-ubuntu-18-04 is a possible duplicate for my black screen problem because there's a message as well on that black screen and also i don't have any Nvidia graphics card so i don't think it'd be any beneficial for me to set nomodeset . I'd be really glad if you can provide me any solutions specific to my problem , Thanks ! – Ashish Bhardwaj Nov 09 '18 at 05:53
  • Aren't you using a Acer Travelmate P259 series? –  Nov 09 '18 at 06:29
  • Yes i am using Acer Travelmate P259 series , model no : N16Q2 . But it does not have a graphics card and it has i3 intel chip . – Ashish Bhardwaj Nov 09 '18 at 08:09
  • @GabrielaGarcia Any possible solution ? i can't think of any solution that fixes my problem , Please help ! – Ashish Bhardwaj Nov 10 '18 at 13:22
  • According to Toshiba yes, it does have a GeForce® 940MX graphics. It must have something because i3s do NOT have integrated graphics, so there. So, back to my first comment, the solution is using nomodeset until you install Nvidia graphics drivers. Nothing else to add. –  Nov 10 '18 at 13:57
