Your machine is a UEFI machine, so bootloaders are stored in the EFI partition, FAT, bootable and you have all that. Lookd like a good UEFI setup, but you must have switched to compatibility mode in your UEFI settings (BIOS).

I own a Toshiba Satellite C50-B-14Z and did install Ubuntu Mate 14.04.1 LTS and works "Out Of The Box" except for screen dimming, but that's all talking about malfunction. I've put an Samsung SSD 840 Evo in the machine to make ik much meaner (...). After installing in UEFI mode I got the same "problems" but after turning CSM on/UEFI off and re-install ...

I really hated the desktop I bought that was causing these problems, but, in service of posting an answer for anyone who maybe had a similar problem. I booted from a boot-repiar usb stick and checked everything under advanced options and it fixed my problems.

UEFI settings for the Toshiba just allow you to set the device (HDD ). In UEFI, the partition marked with the boot flag is the location of the bootloaders. Then with a tool like efibootmgr, you can set the paths to bootloaders and their bootorder. It doesn't boot in UEFI mode because you have no bootloaders in the EFI partition. Apparently you have ...

Edit /etc/fstab and add the noauto option after in the options column. See more details here: How can I prevent ubuntu from mounting particular partitions/deivices?

Remove it from /etc/fstab (that file is used for fixed mounts). From command line use either of these: sudo nano /etc/fstab sudo gedit /etc/fstab sudo vim /etc/fstab and put a # in front of the line that mounts that disk. Save and next reboot it will not prompt for it. If correct you can next time just remove that line from /etc/fstab since the paritions ...

I finally found the answer in this similar question: APT wedged by kernel version mismatch I manually installed linux-server 3.2.0.74.88 as shown in the answer to that question and everything was sorted. Many thanks to Eliah Kagan for a thoughtful, useful and comprehensive answer.

My suggestion is: Changes in the UEFI BIOS to Legacy. Start with the option to try Xubuntu. Open a terminal and run it: sudo -i gparted From gparted delete the partition table and creates a new table msdos. Then create three partitions, A primary, active, ext4. size 45 gigabytes. Free extended rest. A logical within the extended. Exchange system ...

Try the below commands to check the boot issue, sudo mkdir /media/fix sudo mount /dev/sda2 /media/fix(replace /dev/sda2 by your drive name.) sudo chroot /media/fix su apt-get update apt-get upgrade Hope this helps.

After analyse your problem I think answer is below PXE over IP is the option to boot from a network source and is a setting in the BIOS. Press F2 go into BIOS settings. In the NIC settings you should be able to turn off PXE boot altogether as this would only be used on corporate networks. In the boot options you can make the 1st boot device the ...

I'll link to the blog/wiki page I found this solution on when I find it, because I really don't entirely understand what was going on. The UEFI boot mechanism, as I understand it, is supposed to interpret the layout of the EFI filesystem and provide the person booting the computer with a choice of which boot loader to use. In the EFI filesystem on my ...

nevermind, this was all my fault. /export/video1 is just an entry in my /etc/fstab file which I had copied from a different setup, which had a hard drive that this one doesn't have. I commented out that entry, and that fixed the problem on next boot.

As long as you're plan is to completely replace Ubuntu with Windows 7, I would boot up the computer with the Ubuntu live CD (or USB). Then run GParted and delete all your partitions. Once that's done, run your Windows installation. You should be good to go.

Well, I´m not sure what Canonical did. When I installed systemd on my Raring installation (as seen in comments), the binary was there. Now it isn´t anywhere, and the changelog before Utopic version 208-8ubuntu1 is useless (utopic does have the binary there), since they just imported the package from Debian, which is a blessing to Utopic users, since the ...

Go to Settings, Users, then you unlock your user. After that you turn off the option to enter automatically in your account. I think that is that, 'cause my Ubuntu is not in English. Hope that it solved your problem.

I would suggest you to install ubuntu on a virtual machine and get use to it. Once you feel comfortable using ubuntu make the partition of your disk or even better reboot your computer with only ubuntu :D https://www.virtualbox.org/ http://www.ubuntu.com/ Hope that helps

During reboot, press Del to get into system settings, then F8 to select which device to boot from. There, select your installation medium. Select UEFI version if you see both. And yes, you have to install from beginning.

I'm sorry to have to inform you of this, but after reading the boot repair report, it would appear that... unless of course you have two hard drives and one has been disconnected, you no longer have a windows partition. In other words it would appear that when you installed Ubuntu, you chose the option marked "use the entire drive" replacing windows, ...

I found a solution here. Commenting out the lines that read "sleep 40" and "sleep 59" in /etc/init/failsafe.conf solved my problem. Saved the file after commenting, and then reboot. Now, my laptop is booting faster.

I will try to answer my own question. Apologies if my use of technical terminology is wrong. Aim: To get Ubuntu to boot as default, and allow me to boot Windows by playing with BIOS. I believe the problem is the EFI on my machine does not allow me to boot from anything but /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi, see here for a discussion of this. The ...

Sounds to me like you are in a Console. See link: http://manpages.ubuntu.com/manpages/raring/man4/console.4.html try this command: startx You might need to login first. In any case, something is wrong with the boot sequence.

You made a little mistake in your command: sudo efibootmgr -v -c -w -L ubuntu_14_04 -l \EFI\ubuntu\shimx64.efi Because the slash is a metacharacter in bash the actual value passed is: EFIubuntushimx64.efi You should put the path in quotes or use double slashes, the following worked for me: sudo efibootmgr -c -l "\EFI\ubuntu\shimx64.efi"

It's hard to boot into Ubuntu without adding the booting entry into the Bootloader. But since you can boot into Ubuntu manually, you can use another bootloader, rEFInd.

I had a somehow similar problem. After installing ubuntu side-by-side with windows 8, it always booted straight into windows. My solution: Even though I installed ubuntu with bios-boot-setting UEFI, I can now boot ubuntu by setting bios-boot-setting back to legacy. For booting windows I set it to UEFI. Of course, entering the bios each time I want to boot ...

Since both OSes had issues, it is not a software issue. Diagnostics cannot check all the possible functions of the hardware. You may be lucky, perhaps it's simply a temperature issue and it's freezing on overheating. What kinds of temperatures are you seeing on CPU and GPU? Does your bios have a system event log? Does it show any failure warnings? If you ...

Such device names are not persistent, udev makes no guarantees that they will be the same. The Arch Wiki says: Because udev loads all modules asynchronously, they are initialized in a different order. This can result in devices randomly switching names. A udev rule can be added to use static device names. You should use labels or UUIDs instead. ...

You might have to create a separate /boot partition(if you have not done it already during installation) I think this can help you: boot partition

I also ended up having the wrong kernel on first boot of Ubuntu 14.04 after installing with an USB stick created with UNetbootin. The symptoms were that the boot partition could not be mounted, since there were no ext2 drivers available for the kernel. The strange thing was that the kernel in /boot seemed to be the correct one, at least based on it's name. ...

If you still have access to the bash shell,try updating the grub to look for devices to mount sudo update-grub This may help in mounting the partition while booting.
