Linux newbie here I've tried to install Ubuntu 17.04 but it crashed and show this message dialog " the 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot. "   This is my boot-info link   Then i try to repair it using boot-repair and follow the instruction until it finish(im not sure i've done it correctly). next, i can boot ubuntu but crash report show up "sorry, a problem occured while installing software. Package :grub-efi-amd64-signed 1.80.2+2.02~beta3-4ubuntu2.2"  Is there any correlation with forcing uefi installation?  Thanks for your help

I am installing Ubuntu 16.04 in an Intel NUC computer with UEFI enabled. I am using an SSD from another computer. During the installation I chose Erase the disk and make a new full install  At the end of the process I see:  grub-efi-amd64-signed failed installation /target/ Ubuntu 16.04    And the system does not boot.  I tried to use boot-repair but apparently it does not solve the problem.

I want to install Ubuntu and learn Linux.  I've been using Raspbian a bit and really would like to get away from Windows as much as possible.  The only problem is some of the games I use requires Windows for now.  Also, I'm taking classes through Coursera and using online tutorials to learn Linux from and would like an operating system installed besides the Raspbian I have on my Pi.  I have a desktop computer with Windows 10 installed on a SSD (M.2 if it matters) and another HDD used to store files. I have a new 1 TB HDD I'd like to install Ubuntu on. My plan is to install it and place the GRUB bootloader on the new drive.  I can then point the UEFI to that drive as the primary boot drive and GRUB should allow me to choose Linux or Windows. My thought is if I do this, I can change the boot order in UEFI back to C:\ drive and have the machine boot directly to Windows as it does now. Then I have the option of having a dual boot system or a Windows only system. Is this viable?  Should I use the whole drive for Linux?    Also, I'm reading a couple different opinions on disabling Secure Boot and Fast Boot from the UEFI.  Any reason not to disable these in my plan above?  Any other advice is welcome. I appreciate the help!

I have installed Ubuntu 20 alongside Windows 10, then removed Ubuntu and grub issues were also solved, now I am unable to install Ubuntu 20 again. I am installing through USB and a black screen comes with some lines.  It is when I am booting the installer. Ubuntu is not installed on my system.

I have a similar laptop to    But I am opening another question as the problem I face is different. The  and did not find any experience with the Ubuntu installation.  After switching from RAID to AHCI, disabling a secure boot, updating the BIOS, and play around with the BIOS option, I am trying to install Ubuntu 18.04.03.  I am not actually installing it but just using "Try Ubuntu". I pass to the bootloader the options nomodeset intel_idle.max_state=1 without which the installation stops very early. I've also played around with ipv6.disable.  Everything stops while turning on services(see attached figure). In particular acpid.service is the last thing I see, then the system freezes.  I suspect it is related to ACPI setup but don't have any clue on how to fix it. Any suggestion is much appreciated.

I've installed Ubuntu 16.04 LTS along side with Windows 10 (I shrinked my Disk using Windows Disk Management) on my Acer laptop (ES1-531-C13G), but when I restart/reboot my system no menu (Grub screen) appears from where I can select the operating system that I want to boot with, but instead, system takes me into Windows 10 everytime. I've tried several things from internet including :    Ran bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi from windows command prompt.  Reset  Bootorder i.e. first Ubuntu then Windows from Ubuntu terminal (after successful Ubuntu installation) etc, but nothing works for me so far. Please guide me !

I installed Ubuntu and after the installation, i can't boot to XP. When i choose XP from the Grub menu, I got black screen for like 30 sec, and then it returns to the Grub menu.  Thanks!

On an Acer PC, after installing any Linux system with any bootloader, I can boot it once, but after a reboot the UEFI Linux entry is gone.  The Linux system's file in the EFI boot partition seems to still be here.  I tried this with Ubuntu and ArchLinux, with GRUB and systemd-boot.  Why does this entry disappear simply by booting the system ?

Accidental BIOS mode install  I have Intel 64-bit hardware with UEFI setup utility. Ubuntu 14.04.1 LTS was  installed as the only operating system on the only drive attached. Accidentally Ubuntu was installed in BIOS/CSM/legacy mode.  Convert to UEFI  While later on learning about UEFI, the goal is to change this existing Ubuntu installation to (quicker) boot via EFI/UEFI. I do still want to have some kind of - 2 seconds displayed - boot menu that allows me to enter the UEFI setup utility. Therefore I think I do need use Grub (can't use an EFI boot stub) and . I have already re-partitioned the drive using a Live CD and inserted a 200 MiB EFI partition in the beginning of the drive and marked that fat16 formatted partition as type id 0xEF.

I don't want to use a GUI, or install any extra packages, and I don't want any data being accidentally sent to pastebin.com and because I do want to know what will be changed exactly, I don't want to use .  Under the hood  Trying to figure out what boot-repair actually does, I found this snippet:     Boot-Repair will convert a BIOS install to UEFI by uninstalling grub-pc, and installing grub-efi, if gpt partitioned.   source:   UEFI mode install comparison  A clean Ubuntu 14.04.1 installation in UEFI mode creates a 512 MiB Fat32 formatted EFI partition. That partition contains one directory /EFI/ubuntu, containing 4 files: grub.cfg, grubx64.efi, MokManager.efi and shimx64.efi. The grub.cfg contains:  search.fs_uuid 7d843e47-3917-4114-8725-55dfa1fbe002 root hd0,gpt2 set prefix=($root)'/boot/grub' configfile $prefix/grub.cfg   Search.fs_uuid points to the UUID of the Linux installation partition, in this comparison UEFI installation Linux is installed partition /dev/sda2 (versus sda1 in BIOS mode installation).   No potential Asrock firmware issues found  Having CSM still disabled in firmware and using the clean UEFI mode Ubuntu installation. Resizing the 512 MiB EFI partition to 200 MiB using a Live CD and gparted results in that its formatting changes from FAT32 to FAT16. The Asrock firmware P1.50 (incorrectly called BIOS by AMI in boot message "BIOS date") is still able to boot into UEFI mode Ubuntu: UEFI+FAT16 = ok. (msdos) using the same Live CD terminal command gdisk and its commands r g p w also results in a UEFI bootable Ubuntu on an MBR partitioned drive: UEFI+MBR = ok.   Question  Does this mean that the only commands I do need to execute - from the legacy Ubuntu install and in this order - are:  # apt-get install grub-efi # apt-get remove grub-pc   ? Or is more needed to be done?

I have installed Ubuntu 15.10 alongside Windows 10 with UEFI. To install Ubuntu, I chose the option install alongside Windows 10 or something similar to this. Then I created a new partition for Ubuntu and installed it. After installation, the boot menu did not show up. Initially I thought Ubuntu has not been installed, but when I plugged in the USB drive and wanted to install Ubuntu I saw an option of reinstalling Ubuntu on my machine. So, I found out that Ubuntu is installed. Pressing F8 and F12 also does not help. Can anyone help me bring up the GRUB boot menu? In Windows, I also entered the command bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi in cmd, but still the boot menu does not show up.  Reply (Himanshu) : Just boot in bios and, if you can, add boot option with name say ubuntu and path EFI/ubuntu/shimx64.efi. No need for live PCB or anything. Move the boot option to top. This is for dell GUI bios but I assume it works for all. Or you may want to see  or , where you can enable Windows Boot Loader for one boot or forever as you wish, and boot Ubuntu from it. If you want now, you can use the installed Ubuntu terminal to use the commands update-grub to use GRUB instead. (Not enough reputation to answer properly btw.)

I installed Ubuntu 18.04 amd64 desktop on Asus Eeepc 1015px, but it hangs on booting. The last message is 'Started User Manager for UID 120'.  I managed to boot up in recovery mode and finished the installation with 'sudo apt-get upgrade', but nothing has changed.  Does anybody know how I can tackle it?  Thanks in advance, Newton.

Today after I installed Ubuntu 16.04 via USB on my pre-installed Windows 8 machine, I was required to restart my computer. After doing so I wasn't offered to select an OS, so after searching the internet, I came across Boot-Repair which I ran using the Try Ubuntu option in my Ubuntu installation USB. Following the boot repair I got a message saying,  If your computer directly reboots into Windows, try to change the boot order in your BIOS. If your BIOS does not allow to change the boot order, change the default boot entry of your Windows bootloader. For example, you can boot into Windows then type the following in an admin command prompt: bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi   After I rebooted my PC, I am receiving the following error message for about 3 seconds, after which it boots automatically into Windows 8, without letting me access Ubuntu. Error received while booting after manufacturer's logo, before grub: Failed to open \EFI\BOOT\grubx64.efi - Not Found   Failed to load image \EFI\BOOT\grubx64.efi: Not Found     start_image() returned Not Found    So I tried the other solution of typing that command in the cmd, to which my surprise, worked, and I am now prompted a window (grub) to choose my OS each time I turn on my PC, but unfortunately, I still receive an error each time, that lasts about 3s, after which I can choose my OS (both are working just fine) and work normally. Do you have any suggestions to get rid of the error message each time I boot my PC?

I just got my new working notebook with Windows 8 pre-installed. After installing Ubuntu 12.10 the grub menu says that there is an "invalid EFI file path" and it won't boot Windows. Ubuntu works fine...  Is there anything I can do about this?
