Fix Grub Not Showing For Windows 10 Linux Dual Boot
For help, knowledge, and fellowship. Skip to content. Quick links. Forum rules Before you post please read how to get help. I decided to put in another HDD and experiment with other distros there.
So I installed elementary 0. Tried the obvious "update-grub" and it doesn't come up. Looking at gparted and other places, seems everything is intact.
And do both Elementary and Windows work when selected? If "yes" to both, boot into Elementary and enter the following command in a terminal: Code: Select all sudo update-grub. Night crew. Grub currently only contains entries for elementary and Windows.
EDIT: No luck on either of those. When I run the "Linux Mint 18" rule as typed above I get the following error from grub: Code: Select all error: no server is specified. Press any key to exit. So will try hd0 and the terminal code above. Yes I can access Windows on sda and my elementary drive on sdc. I have a bunch of install USBs so if needed I can boot to those. I'm backing all my stuff and now and getting ready for a clean install cause I have work I have to get back to and can't be just missing my Mint partition.
However, after I posted I realized that if that were not the case then it also would not find Windows So, false hope on that one. Running out of ideas. What does sudo efibootmgr -v return? As I was backing up my files I realized everything was still intact. Infact, here's the contents of the grub. Simply type the menu entries you want to add after this comment. Be careful not to change the 'exec tail' line above. I hesitate to suggest that though, because if fix doesn't work I don't know if it would then mess-up what is still working -- booting Elementary and Windows.
If you see "efi" listed in output, you are booted in EFI mode. Shouldn't it have just realized there was already a grub configuration file and just added the entry to it. I decided to go for broke and experiment a bit.
I added a few lines to the grub file located on sdc elementary and then run "grub-update".I didn't see this detail anywhere else, and it's the primary reason for this post's existence. When I logged into Windows for the first time after installing Linux Mint The solution to that problem is described in step 7. Here are basic the steps I took, in case you want a tl;dr.
More information is included further down. Shrink the Windows 10 partition using Windows Disk Manager, which will create a large chunk of unallocated space on your hard disk. Boot up Linux with a live USB and begin installation. None of the distros I played with recognized the existence of Windows Assign the remaining unallocated space for swap.
Continue with the install normally. There are many tutorials online about dual-booting a Linux distro onto a Windows 10 machine, but none of them got me from start to end. Some were simply updated versions and often just updated titles of articles about dual-booting Linux alongside Windows 7, and provided no new information pertaining to a UEFI secure-boot system.
The new UEFI system has thrown a hefty wrench into the otherwise smooth process that was installing Linux, so there's not yet a flawless, widely accepted method.
It's likely the authors of the mostly-adequate articles simply didn't encounter the same problems I did, and thus didn't address them.How to Fix Dual Boot Problems
For the same reason, you may find that this post doesn't address an issue you encounter. This is not intended to be a tutorial, though some people may find it useful.
Windows 10 not showing up in dual boot menu(GRUB)
I'm going to try to keep this as concise as possible, so if you desire more information about UEFI, Linux, Windows 10, or anything else mentioned but not illuminated to your liking, you'll have to rely on your Google-Fu. I'll try to keep the explanations succinct. This is probably not an appropriate guide for beginners. It's written with the assumption that the reader has installed a Linux distro before.
If you choose to replicate anything I describe here, you're on your own. As always, back up your data. Background: I installed Linux Mint In all the dual-boot Windows and Linux setups I've done I've lost count Once the drive is booted, up comes the grub menu that lets you select between Windows and Linux.
What happens when you select the hard drive as the boot device? If you don't get grub's menu, something in the install got sideways.

However when I turn on the computer and hit the escape button.
First it tells me if I want the multi boot menu to press F12 which gives me that menu. It gives the three choices I mentioned. If I choose the Hard Drive and hit enter. It goes straight to Windows. The others just give me a blank screen.
The second one is the Hard Drive, because when I have a disk in the bay, it opens the disk if I click on that one. I expected to see something else, as I have a dual boot on my Acer Netbook and it gives me the choice of XP or Ubuntu likeise both in safe mode, or regular mode.
It looks totally different than this. This looks like a hardware menu. Yep, F12 gets you the hardware boot menu. That's OK, but with a dual-boot install, you will just select the HD anyway. Same as just letting it boot the default device.
For some reason, the Ubuntu install didn't put grub in the MBR, it seems. Did you select where to put grub during the install?Forums New posts Search forums. What's new New posts New profile posts Latest activity. Members Current visitors New profile posts Search profile posts.
Hi Yaraand welcome! There are probably a few ways to fix this, but strangely enough, one of the easiest is from Windows. When starting the computer, before Windows starts This is how you probably get into Setup too, but this time look for Boot Menu or Boot Options, and pick that. I'm on my phone and working from memory, so this part is a little fuzzy You may need to select the double dots. But if it boots okay, then this should make grub boot first for you I don't remember if there is any response to the command, but as long as no errors, you should be able to reboot now and get grub first.In some rare cases, the boot partition may become corrupted or badly configured.
In any case, the Boot Repair utility can work like charm. This tool is free and available for Windows and Linux Ubuntu and derivatives. If you have multiple OS installed, just boot into the one that works and let the tool do its job. Make a live USB flash drive and let it do its job! The installation process is quite simple. Boot Repair uses online paste services. The info is super useful in debugging complicated GRUB configurations.
You can upload it directly to the Ubuntu pastebin for easier sharing with others. There are multiple options available that you can tweak. You can also place GRUB on a different device. Boot Repair works the same on Windows.
The simplicity of this tool makes it easier to fix your system without having no geeky knowledge at all! Of course, the tool is also capable of doing advanced tweaks to the boot configuration without any problem.

If I'm missing some pertinent bit of information, please point it out. This went along well, and I seem to have completed it without a problem.
However, upon restarting, the boot menu refused to show the Mint OS. It noted that Mint had installed to the partition I assigned it to. Perhaps some boot menu setting was preventing the recognition of the new OS, but with my limited understanding my fiddling proved unsuccessful.
I feel like I'm missing some obvious catch that prevents recognition, and I don't fully understand what I'm missing. Hi there, Quote:. Originally Posted by Fruffles. In sda, or in sda1?

Well, from your description you might have installed GRUB to sda1 instead of sda. Thread Tools. BB code is On. Smilies are On. All times are GMT The time now is AM. Open Source Consulting Domain Registration. Search Blogs.

I recently installed Phoenix OS alongside my windows 10 on a partition. It is working fine except now imI unable to go back to my windows I'm using grub dual boot menu, but it only shows Phoenix OS.
Before i was using grub menu, the laptop was directly booting with phoenix. Please help. All files seem to be in order to me, so I'm assuming that my windows is still intact only im unable to access it. Did this solve your problem? Yes No. Sorry this didn't help. But this requires me to run some commands which are run in Ubuntu terminal, i have no clue as to what to do with those. Phoenix doesn't provide any such thing. You can try boot-repair-disk.
See this sourceforge link. I was wondering if i should do a clean installation of windows? That seems like the easiest solution so far. Can i install it on the C: partition, in which the previous windows was installed?
Will my data be preserved? There's only one partition on my computer so everything is on the C: drive. Please guide me through it. The problem is not solved, i never reached that stage as the laptop is not failing to boot- it is opening with phoenix just fine. Only the menu doesn't show windows I tried editing the menu. I received the following error after rebooting and selecting windows 10 from the list:. April 7, Keep in touch and stay productive with Teams and Officeeven when you're working remotely.
