Hi there im quite new to Linux  I have problem with my grub  Windows entry show twice in the grub and probably in wrong partition    As you can see there is 2 entry for Windows 7  I can only boot to windows using loader on /dev/sda2  I think loader for windows should be on /dev/sda1, but the loader on it render black screen to me  I think i did something wrong with my windows and endup with this grub..  Is there a way to fix this? (remove duplicate entry and change it to /dev/sda1)  And here is my partition

I have Ubuntu installed alongside of Windows and in bootloader (grub) these operating systems as all of yours are with long names! How can I change the names in grub? for example I want to change the 4th one to "my fathers OS" and when I choose it in the grub it will go to the Windows.

I'd like to ask for help getting grub-reboot to work.  The theory: According to  (and other sources) I should be able to choose the kernel for the next reboot, using grub-reboot. However, this does not work for me; grub always boots to the default kernel.  Here's what I tried:  $ grep GRUB_DEFAULT /etc/default/grub GRUB_DEFAULT=saved $ grep "menuentry " /boot/grub/grub.cfg  menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-f3a807d1-3fd6-4970-b741-5382e9801060' {     menuentry 'Ubuntu, with Linux 4.4.0-43-generic' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-4.4.0-43-generic-advanced-f3a807d1-3fd6-4970-b741-5382e9801060' {     menuentry 'Ubuntu, with Linux 4.4.0-43-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-4.4.0-43-generic-recovery-f3a807d1-3fd6-4970-b741-5382e9801060' {     menuentry 'Ubuntu, with Linux 4.4.0-36-generic' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-4.4.0-36-generic-advanced-f3a807d1-3fd6-4970-b741-5382e9801060' {     menuentry 'Ubuntu, with Linux 4.4.0-36-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-4.4.0-36-generic-recovery-f3a807d1-3fd6-4970-b741-5382e9801060' {  # Version 1, using the name $ sudo grub-reboot "Ubuntu, with Linux 4.4.0-36-generic"  # Version 2, using the id $ sudo grub-reboot gnulinux-4.4.0-36-generic-advanced-f3a807d1-3fd6-4970-b741-5382e9801060  # Version 3, counting $ sudo grub-reboot 3   Neither of these commands seem to have an effect; after reboot, I always end up with the 4.4.0-43 kernel.  Note: This is on Ubuntu 16.04 Xenial. It is a server machine and I don't have access to the console during boot, so I can't look at the grub menu :(

I used to have Windows 8.1 - Linux Mint dual boot. I succesfully removed Windows from the system but Grub still shows Windows in boot options:    I would like to configure the system the way, that on start up I directly load into Linux Mint without seeing Grub screen options at all.  What I tried so far:   sudo update-grub sudo sed -i 's/GRUB_TIMEOUT=10/GRUB_TIMEOUT=0/' /etc/default/grub  sudo update-grub Deleted Windows entry using  efibootmgr; it was entry Boot0003, it is no more there:  BootCurrent: 0002   Timeout: 0 seconds   BootOrder: 0002,0004,2003,2001,2002   Boot0000* EFI Network 0 for IPv6 (70-54-D2-8C-E9-B5)    Boot0001* EFI Network 0 for IPv4 (70-54-D2-8C-E9-B5)    Boot0002* ubuntu   Boot0004* Ubuntu   Boot2001* EFI USB Device   Boot2002* EFI DVD/CDROM   Boot2003* EFI Network    3 followed by deleting directory Microsoft from /boot/efi/EFI. Currently /boot/efi/EFI has three dirs left: Boot  toshiba  ubuntu   Is there anything else I could do?

After having installed the 64bit version of Ubuntu 12.04 on my Lenovo B570 I ran into the same problems I had when installing 11.10 with Grub not playing nicely with a uEFI system. I used the same technique as last time to solve the problem (using a Super Grub Disc LiveCD session to repair Grub) and my system happily dual boots between Ubuntu and Windows 7  However now when I boot up the Grub menu only displays   Ubuntu, with Linux 3.2.0-24-generic Ubuntu, with Linux 3.2.0-24-generic (recovery mode) Previous Linux versions Windows 7 (loader) (on /dev/sda1) Windows Recovery Environment (loader) (on /dev/sda4)   I no longer see the option to use Memtest86+ which was there previously, having checked in the Ubuntu Software Center I can see that the package is installed, but how to I make the option to run it once again appear in the Grub menu?  I've tried:  sudo update-grub    which doesn't make any difference.  sudo chmod +x /etc/grub.d/20_memtest86+    results in:   chmod: cannot access /etc/grub.d/20_memtest86+': No such file or directory   and entering  ls /etc/grub.d/   results in:  00_header        10_linux      30_os-prober  41_custom 05_debian_theme  20_linux_xen  40_custom     README

After today's update, Ubuntu asked me to replace some files and I blindly accepted. After I restarted PC after the update, I saw duplicate entries in the grub menu:    Here's the image of the grub customizer.    Apparently, Grub Customizer can not save edited information.  Is there a way to remove duplicates from Ubuntu 12.04 grub menu and set Windows 7 on first position?

I installed Windows 7 on one partition and formatted the other where I had Windows 10 installed leaving only that one Windows 7 OS on my drive, but I still have two OSs offered in Windows Boot Manager. What is even weirder is that their names are reversed, when I choose Windows 10, it's Windows 7 that gets loaded.

After installing the Windows 10 upgrade on my laptop, it ruined the grub boot manager, and I could only boot in windows 10. I fixed the boot manager using a live cd with the boot-repair tool, but it only recognized the Ubuntu partition, and not the Windows one.   So I edited the /etc/grub.d/40_custom file and added the following contents:  menuentry "Windows 10" {     set root='(hd0,3)'     chainloader +1 }   After running sudo update-grub2, I got an entry in the boot menu, but the partition does not load. It gives the following error:  Error: Invalid signature.     Does anybody know how one can overcome this error?   My most recent boot-repair dump is here: , and the partition I want to boot is this one:  sda4: __________________________________________________________________________      File system:       ntfs     Boot sector type:  Windows 8/2012: NTFS     Boot sector info:  No errors found in the Boot Parameter Block.     Operating System:       Boot files:        /bootmgr /Windows/System32/winload.exe

I've posted a question  that I have a 32bits windows 7 on a dual boot machine with ubuntu 10.04 upgraded to 11.04. From the responses I had from the questions, I decided to reinstall the windows 7 but this time a 64bits version.  I've install the grub on the first section of the HDD on which ubuntu is install, meaning the 2nd Drive.  I still want guidance before I proceed.  What would you suggest me as best way to achieve that without disturbing the boot loading.  thank you for reading this.

I'm very new to Ubuntu, and have come to this point that I can't boot back to my Windows Vista anymore.  I thought that I would get some kind of dual boot in the beginning when booting my computer, but this doesn't seem too happen and I don't have the slightest idea on how to fix this. I was looking for help here at askubuntu, but I couldn't seem to find anything. I'm too new with this software.  I'll need hints and tips on how to fix this  Thanks for your time folks!

I did a fresh install of ubuntu 11.04, then I installed Windows 7. So I decided to fix the grub after win7 install using the ubuntu 11.04 Live CD.  Disaster:  instead of  $sudo grub-install --boot-directory=/media/uuid/ /dev/sda  I entered  $sudo grub-install --root-directory=/media/uuid/ /dev/sda  Now when my system boots, it stops at the grub console  grub>  My problem is exactly as this one  but I have not been able to fix my problem. Thanx for your help.

My operating system was Windows 7, and recently, I installed Zorin OS (linux based on Ubuntu). At first, when I turned on my laptop Windows started automatically. I used a program to make the Windows boot loader come on and ask me what to start.   If I chose Linux, then the Linux GRUB comes on and asks me what to do. I want to remove the GRUB. I want to keep my Windows boot loader.

I've read several answers to related questions here, but have not found one that matches my situation.  I assisted a colleague to reinstall Windows 7 from a recovery partition. We then booted into Windows, shrank the Windows partition (/dev/sda3) and the installed Ubuntu 12.04 (we partitioned the remaining space into / (sda5), /home (sda6), /swap (sda7) and free space for another Windows drive later.) I specified GRUB to install to /dev/sda. /dev/sda1 and /dev/sda2 were recovery/system partitions.  After rebooting, grub showed the Ubuntu boot options in the menu, and an option for a Windows recovery on /dev/sda1 and a similar one for /dev/sda2. It did not show an entry for Windows 7 on /dev/sda3. I booted into Ubuntu and ran sudo update-grub, but this failed to detect Windows on /dev/sda3. I checked the contents of /dev/sda3 and Windows is still there.  I hope I can resolve this soon, as this is not a good first impression of an LTS release to someone who has just decided to start using Ubuntu/GNU/Linux!

I have two disks in my system:   Non-UEFI windows 10 install UEFI kubuntu 16.10   This system is my home server. I'm migrating from Windows to Kubuntu, but it will take a while since I can't yet duplicate the entire functionality. In the mean time I want to run dual boot so that I can run the server as was (windows) while I'm setting up the Kubuntu deploy in any spare time I get. So:  I'd like to add windows boot to grub's target list, however update-grub does not find my Windows bootloader.  I'm guessing the problem is that it's searching for an EFI boot while there is only a legacy BIOS one.  Is there a way I can add my Windows install as a grub target?
