So this has been a wild ride of a day, I started by trying to remove Ubuntu, messed up and removed GRUB, tried to fix it using a Windows 10 repair loaded onto a USB, that didn't work, reinstalled Ubuntu, discovered that GRUB was no longer loading. So I looked around found the Boot-Repair tool, used it. Now I have GRUB but it only lists UBUNTU and Advanced UBUNTU Options.   Link to my fdisk -l and parted -l results

I installed Windows on my computer, followed by an installation of Ubuntu. However, now I'm unable to boot into my Windows install.  What can I do to fix this?

I installed Windows 8 and after that I installed Ubuntu. This are my partition now:   70Gb --> Windows 8 50Gb --> Ubuntu 12.10 100Mb --> UEFI 300Mb --> Recovery   I installed the GRUB on /dev/sda. Then, after GRUB not showing up and booting directly into Windows 8, I turned the laptop off and booted again into Ubuntu LiveCD and ran the Boot-repair utility, it give me  but it didn't solved the problem.  My Laptop still boots directly into Windows 8, without GRUB or Ubuntu even showing up.

I'm new to how Ubuntu works and installed it yesterday alongside Windows 7, but in doing so I have created a few problems. I have partitions for Windows, Ubuntu, System Recovery, and storage for all my files with the intention to access them on either OS, but I don't even see all of my drives listed on Home Folder. Not to mention that  during the Ubuntu instillation I managed to screw up any chance of booting to the Windows side of things at all. I'll fix Windows once I get my hands on a copy in a couple days, but in the mean time any suggestions for accessing my files?  If you need me to find any data about my computer to help you figure out what's wrong with it, please don't hesitate to tell me what I need to show you. Thanks

I recently repartitioned my HDD and I have damaged GRUB on my system. On boot I get the GRUB rescue prompt and I have to go through the following steps in order to boot normally:  set root=(hd0,msdos6) set prefix=(hd0,msdos6)/boot/grub insmod normal normal   (Those steps were found on another post on here!).  I'm very tired of repeating this on every boot, how do I permanently fix GRUB?

Recently, I installed Ubuntu 10 Netbook edition (on my netbook, yes, obvious). My battery died literally, while I was using Ubuntu.   Now, when I restart the computer, it seems that GRUB has duplicated all of the entries in the MBR that pertain to the partition that houses my Ubuntu install. For example:  Ubuntu ... Ubuntu ... (Recovery Mode) Ubuntu ... Ubuntu ... (Recovery Mode) Memtest ... Memtest ... Windows (Vista loader) Windows (Windows 7 starter loader)    When I try to access either of the two Ubuntu instances in the boot loader it presents me with an error akin to this:   ...numbers... Kernel panic ... VFS unable to mount...   What I would like to do is:  Wipe out grub, and Ubuntu, and then reinstall Ubuntu (I really only use it for emacs and ess for R so there's nothing in the home directory that I need to backup)  How would I go about "resetting" my system? Or fixing the issue that I have.   Thanks in advance!   BEB

Ok, so I'm such a newbie to Ubuntu and I bought a Windows 8 pre-installed laptop last month.  I updated to Windows 8.1 and then I thought about installing Ubuntu as a dual boot so I could mess around and learn more about it.   So I followed a Youtube tutorial (  ) and I got my stuff working fine.   The first few times I booted I got the GRUB menu instead of my default HP Boot OS Manager, and I was able to select my OS.   So I went to sleep and the next day I turned on my computer and the GRUB menu did not show up. I tried several times and it didn't automatically show up.  In order for me to see the GRUB menu I had to turn on my PC and on start had to press ESC to pause startup and press F9 to get boot options. Then from there I had to pick from OS Boot, Ubuntu, Ubuntu (Yes there were two Ubuntus available) and a default EFI file thingy.   When I click the first Ubuntu I get the GRUB Menu (I was too scared to try the second in case I screwed my laptop up) and I can safely load Ubuntu from there and use it (although I do have to increase my brightness every time I load Ubuntu because it somehow reduces my brightness to complete darkness on boot)  So my problem here is why isn't my GRUB showing on boot, after it worked on the first day?   My laptop is a HP TouchSmart j-078CA.  EDIT 1: FYI I just switched to Ubuntu LiveCD to check my Installation and found out that one of my partition is flagged as msftres. Here is a screenshot of my GParted on a LiveCD:

So it's time to ask my first question, something I've been struggling with for a while now. I know there are some questions around the same topic, however, none of them (which I could find) have been of any help.  Before you ask, I want to do some explaining of the core problem.  Why have I not just installed it in UEFI mode?  I was unable to boot the install (or live mode for that matter) in uefi mode. After some time spent searching on google I noticed that several people have had this exact problem: after the menu appears (the uefi one), whatever I do simply results in a black screen.  After reading this article , I though I'd try installing ubuntu in legacy mode, and then use boot-repair to convert my install to uefi.   NOTE: I am dual booting ubutnu alongside Windows 10. Currently I have to enter the bios settings to enable uefi boot in order to enter windows and vice versa.   What I have tried  Boot-repair  I then tried, of course, boot-repair while in a legacy mode session only to get this error message:     The current session is in Legacy mode. Please reboot the computer, and use this software in an EFI session. This will enable this feature. For example, use a live-USB of Boot-Repair-Disk-64bit (www.sourceforge.net/p/boot-repair-cd), after making sure your BIOS is set up to boot USB in EFI mode.   Boot-repair live usb  I tried creating a live usb with boot-repair 64bit only to encounter the same problem as when booting the ubuntu install  Why do I need to boot with UEFI?  Well I don't REALLY need too boot using UEFI, however, my current windows install does, and it would be great to be able to choose whether to boot windows or ubuntu without having to switch between legacy and uefi.  Need any more information?  Is there a way to manually create the /boot partition and do the necessary changes for my system to boot efi?  Other suggestions?  Thanks  EDIT:  While I have tried both on and off, secured boot has been turned off for most of my attempts.  Edit #2: (In response to Rod Smith and comments regarding more info)   I have tried rEFInd boot manager, it encounters the very same problem I have tried rufus (Windows) and unetbootin (Ubuntu) for creating the usb media, both of which producing valid media (for other computers at least) I have a friend with (almost) the same computer with the same problem Very few distros work, Arch and Gentoo are among those who do work I have a GTX 1060 card on a Multicom laptop Windows does indeed use GPT and UEFI boot   Many of my assumptions have been made after reading this post right here:   Especially the text right after something describing my problem:     There is no solution for these errors and the workaround is to disable UEFI to enable the Ubuntu installer to run in legacy mode; after which boot-repair can be used to install grub-efi which then allows/needs UEFI switched back on before Ubuntu will boot using UEFI.   I actually assumed I couldn't reach the F6 menu at all, but now I haven't had time to recheck that.

I have made a BOOTABLE USB installation of Ubuntu 13.04 using . I also have Windows 8 on separate partition. After I finished installing Ubuntu 13.04 from the USB, it went straight to Windows 8 without Grub showing to ask me to select an operating system, how can i fix this ? I don't have UEFI or secure boot.

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 just installed a fresh copy of 12.04 on a new Lenovo ThinkCentere from a USB drive, and when I restarted after installation, the boot sequence didn't find the OS. Instead I got the 'no operating system found' error. When I started Ubuntu from the USB, I could see the HDD and that it had all the installed files. I just couldn't boot into it. It appeared that GRUB was not at the right place... or that there was something funky with the MBR. What is the simplest way to fix these sorts of errors?  Thank you,  EDIT: It appears the problem might have to do with UEFI and GRUB...

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.

I searched the Internet for instructions on how to remove , but the only thing I could find was using a Windows DVD to "repair" the system. I previously had a Windows/Linux doal-boot and removed Windows ( + ), but GRUB is still installed with only one entry: the Linux one.  How can I uninstall GRUB and directly boot on a -based OS?

I installed Ubuntu yesterday alongside Windows 7 and whenever I start my computer I don't have the option to boot Windows. When the computer starts it goes straight to Ubuntu without giving me an OS selection menu. When it goes to Ubuntu it gives me Ubuntu repair options and Ubuntu normal start option. I still have all of the Windows 7 files on my hard drive, but Windows 7 has no way to boot.

My computer doesn't boot. I format my Toshiba laptop with a bootable USB drive. I make this , and when i restart the computer after the installation, my computer does not boot. Then i run boot-repair and finishes with this . I reboot ant nothing happens. I review some questions before, but could't find anything yet. Can someone help me please?

First some background: I have dual-boot Windows 7 / Ubuntu 13.04 on Lenovo laptop. As I did the installation about 1.5 years ago and was then even more un-savvy linux user than I am now, I can't recall everything I did to get both OSes up and running. However, I do remember that it was quite troublesome procedure (running boot-repair at least once).  Now I'm considering trying another linux distro in addition to Ubuntu (most likely Arch), and this time I'd like to do it in a way that I have an idea what I'm doing (and possibly learn more about 'inner workings' of linux distros).  So that's enough for the background. Now my question is: How do I get information on what is my current grub / boot-loader configuration?  This seems to be first and quite separate issue to consider before even dreaming about installing a third OS and more advanced messing with partitions and boot.

I installed Ubuntu in the dual-boot configuration so that I can still boot up in Windows. But I just want to get Windows off of the machine.  Anyone know how to do this without having to go through another Ubuntu install? Also are all of the Ubuntu updates safe to take? Does Ubuntu have restore points in case something goes haywire from the updates?

After successfully updating my bios,  and I ended up with a blinking cursor on the top left corner of a black screen. No errors, no nothing. The bios now only listed a SATA: &lt;disc name&gt; boot option in place of the usual UEFI ubuntu one. I'm using a GPT partitioning scheme.  I eventually found that the working solution was to properly reinstall grub-efi-amd64. So, how do I do this ?  PS: Actually, i succeeded to reinstall GRUB2 EFI on my own and will post my answer here as I was unable to find any complete how-to on this.
