It only takes a minute to sign up. I have both Windows 7 and Ubuntu installed on a shared machine. Because a lot of the non-developers use Windows, I'd like to change the boot order to make it easier for them. You can use an easy-to-use the GUI application called Grub Customizer to make your life a little bit easier.
As the name suggests, you can do much more than just reordering GRUB menu entries with it. Take a look at it if you're interested.
For example, if somebody has two OS-es installed Windows and Ubuntuand then installs a third OS Manjaro, etc and then tries to follow the above answer, Grub Customizer changes will not work when made from the second OS Ubuntu, in the example. The program has to be installed in the thirs OS, as it seems that Grub Customizer can only edit the Grub files created by the installation of the system on which itself is installed.
The files that determine the Grub boot menu come in most cases with the latest system installed on a machine, so Grub Customizer has to be installed and used from that Linux system. You can also change the grub default boot entry from the command line without having to install any additional tool. This won't change the order in the list but it will allow a different OS to boot by default, which sounds like what you may want anyway. In case something goes wrong, you can easily revert to the known-good copy:.
Note that the menu items are zero-indexed. That means that the first item in the list is 0 and that the sixth item is actually 5. So to boot to the sixth item in the list, the line would read:. Each menu entry is specified by a line of type:. This may be a better method, as it does not depend on the order of the entries, which could change.

From the tombuntu site article by Tom :. Before you make any changes to it, it may be a good idea to back it up by creating a copy:. This change will make it easier to change the default item later. The configuration change we made allows the grub-set-default and grub-reboot commands to be used at any time.Joinsubscribers and get a daily digest of news, geek trivia, and our feature articles. You can change its settings to select a default operating system, set a background image, and choose how long GRUB counts down before automatically booting the default OS.
For example, on Ubuntu, there are scripts here that configure the default theme. For an easy-to-use terminal-based editor — Nano — use the following command. You can use any text editor you like, of course — including the standard vi text editor. As with any other configuration file, you need to edit the options to your desired state and then change the file. If it does, edit the existing line instead of adding a duplicate one.
You can also specify a label in quotes. This option specifies GRUB will be hidden and it will automatically boot to the default OS after 0 seconds —immediately, in other words. You can still access the menu by holding Shift as your computer boots. GRUB will automatically bot the default operating system after a period of time, usually ten seconds. During that time, you can choose another OS or leave it be to automatically boot.
The image file must meet various specifications. You could also use a TGA image file. Your changes will become part of the grub. The Best Tech Newsletter Anywhere.

Unless you have multiple operating systems installed, this bootloader is normally hidden — but it provides options you may sometimes need. The boot loader is the part of Linux that loads when you first boot up your computer. It normally just boots the Linux kernel, which loads the rest of the operating system — but it also provides a menu with options of its own. By default, Ubuntu and other Linux distributions hide this menu.
You can access the hidden menu by holding down the Shift key at the very start of the boot-up process. Use the Up and Down arrow keys as well to select and option in the menu, and press Enter to boot the selected menu entry. Your Linux distribution should automatically configure GRUB to list your other installed operating systems when you install it.
You can also access some additional tools here, although the exact options available will depend on your Linux distribution. Press Escape or reboot your computer to leave the memory-testing environment. GRUB2 is also where you can choose between your installed Linux kernels. To switch to a new Linux kernel, you have to reboot your operating system and boot into it.
This all happens automatically the next time you boot. However, in some cases, a new Linux kernel might have a problem on your system. It may refuse to boot after you update, or you may experience hardware problems. For this reason, Linux distributions generally keep at least one older Linux kernel around. You can switch to the older Linux kernel by rebooting into your GRUB boot loader and selecting the old kernel.
The most recent kernel appears at the top of the list, has the highest version number, and is selected by default. Other Linux distributions may provide something similar. If you ever need to fix your Ubuntu system, the options here may help. GRUB2 has some more advanced options. You could boot into runlevel 3 — the standard system without a graphical desktop — or runlevel 1 — a single-user mode designed for administrative tasks.
To change boot options, select a boot entry with your arrow keys and press e. Next, we pressed space and typed 3 to specify runlevel 3. Even people who need to use GRUB2 will generally just use it as a menu to choose their desired operating system when they boot their computers. Image Credit: Paul Schultz on Flickr.

Since we launched inour articles have been read more than 1 billion times. Want to know more?This tutorial shows you how to easily change grub boot order to make Windows as default OS in Windows-Linux dual boot with the help of Grub Customizer. Many people prefer to install Linux in dual boot mode with Windows.
At the boot time, on the grub screen, if you do not choose Windows for login within 10 seconds default Grub timeoutit boots up into the Linux. This grub behavior creates problem if you prefer to have Windows as your primary OS. You have to wait till the computer boots up and stay close to your computer to choose Windows for login. You can change the grub behavior to make Windows your default OS in dual boot by editing the grub configuration file.
Change Boot Order in Windows Linux Dual Boot with Grub Customizer
While this is my preferred way, I can understand that as a regular Windows user you might not want to use the command line and would prefer a tool with graphical user interface. I was asked by a few readers to provide a tutorial on using a GUI tool to change the boot order to make Windows default OS instead of Linux.
Startup Manager was the best GUI tool to configure grub. However, it has been discontinued. The void of Startup Manager is somewhat filled by Grub Customizer. While Startup Manager was just focused on giving you few options to configure the boot menu, Grub Customizer focuses on all the aspects of customizing Grub, and hence it is a little complicated for beginners.
The tutorial should also work on all Ubuntu versions including All Windows versions including Windows 10, 8 and 7 should work fine. It requires the admin password because you are dealing with an important configuration that requires root privileges.
Enter your password. You can see that Windows lies at the bottom after so many Ubuntu options. All you have to do is to move Windows over the first Ubuntu. You can use the arrow option from the top menu for this task. Once done, you should have Windows on the top of this list.
At this point, you should save this configuration.Howto Change Linux Boot Options and Splash Screen
If you do not interact with the grub menu at the boot time, it takes 10 seconds to boot into the default operating system. You can use Grub Customizer and reduce this boot time to something of your choice like 3 seconds or 5 seconds.
You can do some other grub customization as well with this wonderful tool. I hope the tutorial helped you to change the grub boot order in Ubuntu and other Linux distribution and make Windows the default OS in your dual boot system. Grub Customizer is an amazingly simple tool for this task.
This is especially important if power goes out and comes back; I won't even be in the house. I started out by installing Ubuntu The internets and this site suggests that the old way to fix this is to run update-grub so GRUB recognizes Windows and then grub-install to put GRUB back on the device.
I have done this, but unfortunately, it still has the behavior as described above, where the BIOS by default chooses Windows Boot Manager. Second edit: Because the correct answer ends up being mentioned in a comment to a response, I'll repeat it here:. There are potential problems and complications with any of these options. The most likely complicating factor is if there are old or alternative ubuntu boot entries. It's important that you move the correct one to the top position in the boot order; if you move the wrong one, you'll end up with either no change in behavior or something non-functional booting, which would make it harder to boot.
If you use efibootmgrthe BootCurrent line may help you to tell which option you should set as the default. There are other ways to do it that are overkill. These approaches run the risk of damaging a known-working GRUB configuration, though. You may want to check out these questions and answers on AskUbuntu if you run into such problems:.
I've been having this exact problem the past few weeks. I figured it out using these options. What I would recommend to you is install Windows 10 first. Then install ubuntu. But I know it is kinda taboo to just say "reinstall your software" so I'll offer an alternative too. Click the "Recommended Repair" option and follow the instructions given. Go through it carefully and read all the commands before executing. This will override the current grub installation with a new one which should hopefully fix it.
I went to the "boot list option" in my bios. Clicked on "Add Boot Option" I am aware that this is bios specific. I then moved the grub entry to the top of the boot sequence, and now it shows as the default entry.
None of above options worked for me with old HP laptop. I found out solution is to set windows boot manager inactive:. Replace 4 with your number of windows boot manager. Run efibootmgr again and you should see star disappear to mark inactivity. The first "menu entry" has a value of "0".

Fix Grub Not Showing For Windows 10 Linux Dual Boot
I would have preferred the computer to wait until I told it where to boot but could not find a way of doing that. All of the Linux distros that I tried just take over without being asked. And I agree with him, it is annoying how the boot loader is often set up by default to boot into Linux too quickly. This first screenshot shows when the computer first boots up. If you are not paying attention then the 5 seconds might elapse and it will boot into Linux without you getting the choice.
You might want to always select which operating system to load, or you might want it to load Windows by default, or a different operating system also installed on your computer. The second screenshot shows the boot menu after you have pressed any key. In this example the boot menu offers the choice between Fedora 8 and Windows. By default Fedora 8 is selected but you can choose to move the arrow keys up and down and then hit the enter key when you are ready.
Open up the file using a text editor, either running the command as root or using sudo. The "hiddenmenu" option hides the boot menu so you need to press a key to get to it, instead showing the example splash screen in the first screenshot above. Fedora 8 by default only allows you 5 seconds before booting into the default option so if you are not paying attention you might miss it and have to reboot before being able to make your selection.
To stop this behaviour and go straight to the boot menu instead of the hidden screen change it to this:. This comments it out and means the boot menu will no longer be hidden, allowing you to always see the menu list when booting up.
If you want to change back to a hidden menu at some later stage you can uncomment it by removing the character. The "timeout" option specifies how long in seconds the hidden menu or regular menu list should wait before automatically booting into the default option.
On Fedora 8 the default is 5 seconds. You can either make it a much longer time, such as 30 or 60 seconds, or disable it entirely and make GRUB always wait until you specifically make a selection. To disable the automatic boot option, "comment" out the line as per the hiddenmenu option above:. The final thing you might want to do is to change the operating system that is selected by default.
Whether you choose to have auto boot enabled or not, the default option will always be selected by default. The options are number starting from 0 in order of the file. In the example menu list above 0 would be Fedora and 1 Windows.Brief: Cannot access Linux in dual boot because system boots straight to Windows without showing the grub menu?
Here is a possible fix for you. So, finally, I upgraded Windows 8. Since, I dual boot Windows 8. But the upgrade to Windows 10 from Windows 8. It just kept booting into Windows 10 at each start up. It seemed like as if there is no way to access Ubuntu at all. It was just the UEFI settings that were different in the boot manager. If you too are unable to boot into Grub and rebooting Windows 10 repeatedly, I am going to present you the simple solution that worked for me.
Warning: Playing with your boot settings can leave your system messed up. Though I am saying Windows 10, the steps are equally valid for Windows 8 and 8. Similarly, I am using Ubuntu in dual boot here but the trick applies to all other Linux distributions such as Linux Mint etc. Search for Command Prompt, right click on it to run it as administrator.
The command should run just fine given that your account has admin rights. I hope this quick tutorial helped you to fix the Grub issue. You can try some suggestions mentioned here to stop dual boot from booting straight into Windows.
I am an avid Linux lover and open source enthusiast. I use Ubuntu and believe in sharing knowledge. Apart from Linux, I love classic detective mysteries. I'm a huge fan of Agatha Christie's work. You can end in the endless loop of system repair, preventing even Windows to boot again. Maybe you should specify it. It did not solve my issue. I have windows 10 and ubuntu on two separate disks, is this dualboot? Please log in again. The login page will open in a new tab. After logging in you can close it and return to this page.
Step 1 In Windows, go to the menu. Step 2 Search for Command Prompt, right click on it to run it as administrator. It did not work? Like what you read? Please share it with others.
