Seeing from the screenshots, your hard drive contains no operating system at the moment, which means you have to install both OSes from scratch. You should install Windows first, then Ubuntu, choosing to install it alongside the existing installation of Windows. You can find information about installing Ubuntu alongside Windows on the WindowsDualBoot help ...

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 ...

When I had the same problem I used to press F2 and the windows boot manager allowed me to chose the Grub and then Ubuntu. Try all the Fcommands and c if that works for you. You don't need to disable secure boot as Ubuntu is recognised by your Bios as asecure OS

Just when your system is booting hit esc or f9 key it will take you to the all EFI boot options there you can choose which OS needs to be booted OS boot manager is for windows 8 and ubuntu on your EXT4 partition.

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 ...

Ok. I've been looking at your Pastebin from Boot Repair, and here's what it looks like to me: You've got all your partitions listed there, and it's listed which ones contain bootloaders. /dev/sda1 seems to contain your Windows bootloaders and a secureboot handler /EFI/ubuntu/shimx64.efi for Ubuntu. I believe there should also be a grubx64.efi in the same ...

I had the same problem when I used to dual-boot and I enabled the windows bootloader to start when pressing F12(you can change this in the BIOS of your PC). I then pressed F12(you PC probably has a different F command) and chose to boot Ubuntu. Downsides to this method: 1. Windows will still boot automatically unless you press the F command when booting. 2. ...

EDIT: Hello, downgrading the bootloader brought me a functional pc. To do that you need your install medium. Boot that up and go to your command line. Then mount your system. sudo su mount /dev/sdXY /mnt # XY the partition you installed / (root) (for example /dev/sda2 in my case) cd /mnt cp -L /etc/resolv.conf etc/ # to get the internet working mount ...

I believe I know what the problem is, and I can tell you how to fix this without deleting or reinstalling Windows. I've run into this problem twice and fixed it both times with this method. You see, prior to EFI/UEFI, there was a grandfathered-in limit of how many partitions any drive was permitted to have. I seem to recall the limit is three, or is it ...

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.

Something is confused here. You do not need this "Reserved BIOS Area" Normally. A 1Mb empty space is normally created before or after partitions because of partition padding, it has nothing to do with booting. Are you using MBR or GPT partition table? It should be GPT. Is the medium you are trying to install from, UEFI-compatible and is it actually ...

As far as I have heard, dual booting (Ubuntu and Windows) in UEFI isn't very clean I need to reinstall it to get it in CSM. This is not true. As @RodSmith already said, there are firmware bugs or seemingly deliberate faulty implementations. The device manufacturers are to blame for this, not Microsoft! (If you're blaming Microsoft and do nothing ...

If you have successfully installed Windows 7 with UEFI then everything should be in place. You would just need to boot the Ubuntu media the same way for installation and it should provide you the install alongside option. 1) Will I lose much functionality or efficiency if I simply switch the bios to legacy and do everything that way, which seems to be ...

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"

Have you tryed enter this in the tty or terminal: sudo apt-get purge -y --force-yes shim-amd64-efi shim-amd64 grub* sudo apt-get install -y --force-yes shim-amd64-efi shim-amd64 shim-amd64-generic and then enter this also in the tty or terminal: sudo apt-get update sudo apt-get upgrade and it might work fine this way.

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. How to install rEFInd in Ubuntu: sudo apt-add-repository ppa:rodsmith/refind sudo apt-get update sudo apt-get install refind More information here: http://www.rodsbooks.com/refind/

The EFI partition just contains a FAT filesystem, so you can mount it, create a directory /EFI/ubuntu and copy /usr/lib/grub/x86_64-efi-signed/grubx64.efi.signed into /EFI/ubuntu/grubx64.efi and /usr/lib/shim/shim.efi.signed into /EFI/ubuntu/shimx64.efi. Now if your nvram boot entry was deleted,m you will need to use efibootmgr to create another. One real ...

To install them I create a / and a /home partition for each distribution, but the EFI boot partition which is created by W8 at the begining of the disk is unique. Looks good to me, I would have done the same. Is there any problem with installing various linux bootloaders in the same boot partition (maybe because kernels get mixed or something)? ...

you have to run sudo update-grub from the OS that created grub (probably ubuntu-studio) otherwise, use bootrepair help.ubuntu.com/community/Boot-Repair help.ubuntu.com/community/UEFI#Converting_Ubuntu_into_EFI_or_Legacy_mode Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported)

Some motherboards have the option to select which OS to boot (mine, for instance). Then you should be able to select "Other OS" option. Look at the UEFI setup. Since you are not going to dual boot, let the installer make the partitions for you. You don't need to worry about them.

If your motherboard fully supports UEFI mode, enable that. Then, make sure when selecting your flash drive, you boot into UEFI mode. To do this, I recommend using dd. To find your flash drive sudo fdisk -l Let's say it responds with /dev/sda /dev/sda1 250 gb /dev/sdb /dev/sdb1 14.9 gb Then you would dd bs=4M if=/path/to/Ubuntu.iso of=/dev/sdb ...

I can get a Grub boot interface by typing: set root=(hd0,5) set prefix=(hd0,5)/boot/grub insmod normal normal And I can then boot into either Windows 8 or Unbuntu. But I really don't want to type that every time I reboot. That was pretty far already, in your UEFI setup you would have just needed to put that into a grub.cfg next to ...

The short answer is, you can't do it. Your laptop isn't the only one. I recall reading the reason is an incompatibility with the linux kernel and the combination of a 64bit processor but a 32bit uefi like these laptops have. it's the baytrail processor and its stupid frankenstein of a uefi that's the problem. from memory the only way of getting linux to boot ...

The amd64+mac version should work on both the Mac and the PC. The difference between the amd64 and the amd64+mac is that the amd64 version is 'multi-catalog', ie it can boot on either BIOS or UEFI systems whereas the amd64+mac version only support BIOS booting. The problem is that Macs are not able to boot 'multi-catalog' disks. However, you can get your ...

It actually is possible. Before I continue, these instructions are meant for blank EFI System Partitions (ESP) and will probably ovewrite existing files, or not work as expected. At least make backups! Adding required partitions for different platforms Platforms: Legacy PC, UEFI-based Windows computer, Apple computer Add an ESP to an existing ...

Well, I found the solution. Apparently, in my computer uefi does not show both boot managers (my previous computer used to do it). When I install Ubuntu his boot loader is set as priority over the Windows boot manager, and grub2 loads and I can choose Windows or Ubuntu. But still, somehow, when I enter the BIOS, uefi restores the priority to Windows. To ...

Have you been booting UEFI before? In that case copy contents of the old EFI System Partition (ESP) to the SSD's ESP, and re-register the bootloader with efibootmgr, else install GRUB to the ESP (note that you need to have at least the grub-efi-amd64-bin package isntalled). Both should give you a ubuntu labeled entry in the firmware (aka BIOS) boot order ...

If you've already installed Ubuntu with UEFI enabled and it works fine, then just use any method you prefer to update Ubuntu, apt or Synaptic or Software Center or an update manager (Software Updater?). I think once Ubuntu's installed it shouldn't change from just updating software packages, UEFI or not. Changing the kernel, that may be a little different, ...

Graphically, you can run the program Software Updater from the dash inside Ubuntu. If you are comfortable running commands in the terminal, open a terminal and enter sudo apt-get update sudo apt-get upgrade This will accomplish the same thing: Update the lists of software with the current versions, and upgrade those which can be upgraded without ...

The best and safest way to fix it is to create a bootstick with Windows 8 installer, from which you can run Windows' boot fix. Boot Repair sometimes does strange stuff, like replacing Windows' boot loader with GRUB2. As the GRUB EFI only loads the normal GRUB2, which is located on the stick, it won't work.

The output of efibootmgr -v shows that /efi/ubuntu/shimx64.efi has been registered as ubuntu. (These new boot entries are usually added with the highest priority.) An output of efibootmgr would have help determined if the order was correct. So from my understanding, it is a matter of changing the boot order so that the entry for grub is the ...

What you need is to boot your laptop from windows, but now that Ubuntu installation altered the windows MBR (master boot record) you are not able to boot windows. To fix this you must boot from windows boot-able USB or DVD, this can be done from this link: creating windows boot-able media After that follow the instructions on MS page.

This is a known problem with FGLRX. To fix it, you need to edit your boot settings. In a terminal, run: hwinfo --framebuffer ## Depreciated, use videoinfo instead! It should spit out a lot of numbers. Choose the resolution that you want (usually the highest). Remember the corresponding code! Now, reboot. In the GRUB menu, edit the entry and add ...

I found out an answer to my problem! I had to boot my laptop into CSM mode, legacy, and install Ubuntu from there. Before, it said that a file was not found, but if I press tab then, I can locate the file and run it from there. It has fixed my problem and Ubuntu can boot up the hard drive from there.

I've had some success with installing linux on this laptop. The UEFI is 32-bit, and so I had to compile a 32-bit UEFI grub to boot. The wireless card in this laptop is also unsupported currently. It's supported in android, but not in the current Broadcom linux drivers.

Using unetbootin to create a boot disk for a UEFI (I tend to use the term EFI, though it's technically incorrect) system is a common mistake. unetbootin, last I checked is not EFI-aware and only makes BIOS-type boot disks. This is where the problem originates. Since unetbootin creates BIOS-type boots disks, you had to enabled BIOS mode in your EFI in order ...

The path that needs to be entered as the Custom Boot image is: When using Secure Boot: EFI\ubuntu\shimx64.efi When not using Secure Boot: EFI\ubuntu\grubx64.efi This is one of two workarounds.
