Okay well nevermind guys I got the answer I needed after even more crazy things happened. In the end I got the dude at the customer service to tell me that the computer that I have is basically useless without Windows 10 and that all the problems that I've been having basically stem from me not having installed that OS in the first place, and that until I ...

As you have placed a brand new hard disk in an UEFI system, you first need to restore the UEFI partition. Try them in the following order: The original System restore DVD/CD/USB from your hardware's manufacturer The Open Source rEFInd Go back to BIOS: no more worries about Unified Extensible Firmware Interface (UEFI) problems. This one is hardware-...

so I returned the notebook and got a new one. Installed Mint on it and went smoothly. Upgrade the Kernel to 4.6 and It's been running for almost an hour now and no problems so far. But I tried using the same wifi driver I had for Ubuntu but it seems like that it's not compatible with this one. Where did you get your driver from? To install the hadess ...

You can't 'convert' Ubuntu to UEFI. It is already installed in UEFI mode, because the uefi bootloader uses an EFI partition (as well as Windows, too). In (old) BIOS mode there is no need for an EFI partition. Legacy bootloader seems to be kinda backup boot mode, in case efi bootloader got corrupted.

You do not have to create a new ESP (EFI system partition). In fact, you must leave the ESP alone as explained in the UEFI Ubuntu help page Make sure you install Ubuntu in EFI mode so you will be able to boot both Ubuntu and Windows from GRUB.


2

You can and should use one EFI partition for all OSes installed. The only concern is if you have many OSes that there is enough space on it. But in most cases this is not an issue since efi files are small.

Make sure your BIOS supports booting from USB - all modern PCs have that, but some may have it disabled in BIOS Settings by default - make sure legacy USB is also on if there is such option. If that doesn't work or is not the case, then try a different tool to make the USB bootable. For example, 1/10 cases when I used Unetbootin it didn't work, but with ...

Which version of ubuntu are you using? Linux kernel? Type in a terminal: uname -a It might be related to: bugzilla eMMC Try upgrading to the latest kernel release (4.6 i think), not the RC's.

I have the same laptop (ideapad 100s) and I recently installed Linux Mint 18 on it.

I had a similar problem like you and I solved it using EasyUEFI which apparently is free for home use (on non-enterprise Windows editions).

Now enter or enter the file path of Shim: "\...

You are correct. The Canonical Kernel Team has enabled EFI_SECURE_BOOT_SIG_ENFORCE in the new 3.19 Ubuntu kernel. That prevents from loading unsigned 3rd party kernel modules. It looks like there is a script with GUI that is supposed to help to disable Secure Boot. It did not work in your case. It depends on specific UEFI implementation in your computer. ...

I found a solution which works for me: I just sudo-copied grubx64.efi in /boot/efi/ (from the /boot/efi/EFI/ubuntu/ subdirectory), so that now I have the file /boot/efi/grubx64.efi Then I indicated this as a reliable file in the setup. Now it seems to work. Thank you, Zanna, for editing, and ubfan1 for your ready answer.

No, the indication from "Software and Updates" is not adequate to confirm that you have no "third party drivers" installed. I had the same issue this morning when installed updates to my Dell 64 bit UEFI system (Ubuntu 15.10). I have a dual-boot setup with Windows 10. Back when I installed Ubuntu last year, I had to install a third party driver for the ...

Remember that you MUST user GPT partition table type to make the UEFI System boot. Some time ago,i had the exactly same problem. I solved it, formatting my disk, and creating a new partition table with gParted from the LiveUSB. The default value for the partition table is msdos, which is for Legacy boot. Change to GPT from the dropdown list. A more ...

The easiest way to check if you have 3rd party DKMS modules is to use dkms status command. But there is a possibility that you installed some modules without using DKMS. But you should know if you installed something from source.

Had the same message,... Basically, if you are using proprietary drivers for your video chipset, or your wireless chipset, you are using 3rd party drivers. Commonly, AMD or nVidia drivers are proprietary. Some Atheros and Broadcom drivers are proprietary, as well. A dead giveaway is if you have dkms (Dell Kernel Module Support) run when you do a 'sudo apt-...

Two other workarounds occur to me, in addition to the one provided by Brady Dean: Workaround 1 Before running the installer, change the GPT type code of the EFI System Partition (ESP) you do not want to use to something other than the code for an ESP. Details of how to do this depend on the partitioning software you use: In gdisk, sgdisk, or cgdisk, ...

Well I didn't find a solution, but I found a workaround. After booting the live cd, run dmesg | grep ata to find the id for the internal drive.

Some reason it doesn't want to save the EFI boot loader properly or it was being corrupted in ...

This is not a bug, it is a feature. As Anthony Wong says, when you install a DKMS package you are compiling the package yourself, thus, Canonical cannot sign the module for you. However, you can definitely use Secure Boot, however this is exactly the use case where Secure Boot is trying to protect you from yourself because it cannot know whether you trust ...

You never 'remove' the grub boot screen because it is part of the grub bootloader. And Ubuntu can't boot up without its' bootloader (namely grub). You can HIDE the grub boot screen (as display it for zero seconds) by installing and using tweaks of grub-customizer. My advice would be to clean up all the mess (delete all partitions you don't need) and do a ...

All these instructions are working in Ubuntu 16.04. I don't know if something is different in Ubuntu 13.04. If you just don't want to use Grub as bootloader, because you don't like it, I can't help you with what you are asking. But if you don't want to use Grub only because it overwrites Windows bootloader, then there is a way to have Grub2 installed ...

Finally, I got it to boot in UEFI. The problem is with UEFI firmware which seems buggy. It does require the EFI partition to be the first one in the GPT table. The partition entries in GPT table were unordered. (EFI was the first one on disk, but 4th in the table). I followed instruction below to fix that: Boot using Live USB Backup GPT table sudo su ...

As you already mentioned, there are two different clocks: The software clock is set and used by the linux kernel and provides the time for all programs The hardware clock (real time clock (RTC)) has battery backup power (i.e. is always running) and is used to adjust the system clock on boot UEFI has no access to the system clock and thus uses the RTC. ...

Searching the Internet leads to the conclusion that the exact same error can be produced in many different situations. That's true. However, there is a single underlying issue.

Step 1: Run the Ubuntu Installer. Select SOMETHING ELSE at the storage configuration prompt.

It would help though if you looked at the logs and gave us some more information on any errors that you find. Can you get to the command line using Ctrl-Alt-F1 ? If you can't do that, then you perhaps have to enter the Grub menu during boot and boot into recovery mode under the Advanced options. You will then be able to get to the command line.

You need first to open gparted (sudo apt-get install gparted) , go to your hard disk with windows and ubuntu , and delete boot flag from ubuntu partition and set it to windows. Now it will boot directly in windows. Now in Windows , you need to delete the ext4 partition (with ubuntu). For partition on windows see ...

I find the answer in http://wiki.osdev.org/GRUB_2. Looks like bootx64.efi itself is GRUB 2. The configuration file grub.cfg read by bootx64.efi is also stored in ESP. By default, the grub.cfg in ESP is a configuration to read another grub.cfg in partition where Ubuntu is installed.

I had this issue too. It was because I was using version of the USB Startup Disk creator that was very old, I think it was on Ubuntu 14.10.

Grub should be able to do this, but you didn't tell it to look for your Windows installation before rebooting.

From yr log it seems that there is a conflict between the way you installed Ubuntu (as if yr existing hw context was BIOS-MBR) alongside a Windows 8 system that is UEFI-GPT based.
