Ubuntu was my first OS. After that, i created another 2 partitions in my HDD and set up Windows 8. Now Windows 8 is running automatically. There is no dual boot option left. Is there anyway to get my Ubuntu system back? or at least save my files? I cannot find the partition that had Ubuntu

I installed Windows 7, which ate Ubuntu's boot file. When starting up the computer, it now goes straight to Windows, without giving me the option of booting Ubuntu.   How can I get Ubuntu back?

I have a formatted 55GB partition as NTFS, the other part of the hard disk has Windows 7.  Is NTFS the right format for Ubuntu? If not how should I format it and with what format?  Once I finish preparing the partition, how do I install Ubuntu on that partition? I'm not sure how to set up dual-boot Ubuntu and Windows.

I'm not sure I'd actually do this, but is there a way to make GRUB automatically select the boot option I didn't use last boot? i. e. If I booted into Windows last boot, it selects Ubuntu. If I booted into Ubuntu, it selects Windows. I was just wondering because I often find myself rebooting to switch OSes, as I have different games that I run on each (though with my new rig I don't need to run stuff on Ubuntu just for lower OS resource usage), and I was wondering if I could make it so that every time I pressed "restart" from either OS I wouldn't have to change selections. In practice this would also affect non-restart startups, so then I might have to boot twice to get the OS I was using last time.

I've already installed Ubuntu 12.04, but I did not make any separate partitions beside the one the operating system is installed on.  Now I want to make a new partition.  Is this possible?

I have Windows 7, and I'm trying to dual boot Windows 7 and Ubuntu. However, when I try to install Ubuntu with a USB, it doesn't give me the option to dual boot. I can only "Replace Windows 7 with Ubuntu", or "Something Else".  I've installed Ubuntu on this computer before, and this option was present. What I'm asking for is a way to get that option, or how to use the "Something else" option.

I have dual booted Ubuntu with Windows 7. I wanted to uninstall Ubuntu. So as per an answer for one of the related questions on this site I did the following:   Deleted the Ubuntu Partition through Windows. As per the answer now I was supposed to boot Windows from USB &amp; then do "repair startup".   But Windows could not find any problem hence nothing was done. So when my laptop booted normally (i.e. from HDD) it was showing some error like GRUB:/ unknown file system. I dont remember the exact words but it was something like this. Thus I couldn't boot windows neither Ubuntu. So again I had to install Ubuntu.  But now my question is how do I remove Ubuntu so that my laptop returns to the previous state of installing Ubuntu?  UPDATE: Seems that it wasnt on this site. My mistake :P .Here is the link

I installed Ubuntu 14.04 onto my Acer Aspire E15. The PC has a 500 Gigabyte HDD.   During the installation it divided the HDD into separate partitions. However every time I turn on the PC it goes directly into Windows 8.1. It doesn't allow you the opportunity to select which OS you want to use.   Question 1: How do I set the PC so it will allow me to select the OS?  Question 2: And if #1 isn't possible. How to I remove Ubuntu from the PC and recover the partition for Windows

I recently got a computer from school. It came with Windows 8.1 installed. I then installed another copy of Windows 8.1 (so it would use the built-in Windows Pro license) and upgraded it to Windows 10. I then installed Ubuntu alongside both Windows 8 and 10. Note that I made a separate 255MB ext2 partition for /boot. Now, when I boot the computer, I first see a GRUB prompt (I already un-hid the grub prompt 'cuz I like it that way) with Windows 8 and Ubuntu options. However, there is no Windows 10 option. If I select Ubuntu, the computer boots into Ubuntu. However, if I select the Windows 8 option, I then get sent to the Windows bootloader, where it then gives me options to boot either Windows 8 or Windows 10. (However, by this point, the computer has already loaded the kernel and all. Apparently Microsoft misunderstood the concept of a bootloader and decided that that meant &quot;boot practically the entire system before actually showing the bootloader&quot;. Typical Microsoft.) How can I disable the Windows bootloader and add a Windows 10 option to GRUB? EDIT: Someone has answered telling me to disable the Windows bootloader. However, I still do not know how to add Windows to the GRUB OS list. Can anyone help with this? EDIT 2: After removing Windows 10 from the Windows bootloader with EasyBCD, it seemed that, after a few reboots, it would continually unhide itself and Windows 10 would reappear. However, I then later deleted Windows 10 from the list of OSes in msconfig, and it seems to have stayed deleted. However, I STILL have not managed to get Windows 10 to appear in GRUB. It's as if GRUB simply doesn't detect it. Also, I'll put this in the question so that people see it - I have tried using boot-repair, however, it has NOT helped any.

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:

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 have a Windows 8 system and was about to install Ubuntu 14.04 in dual boot mode, when I heard about Windows 10 releasing. Now that the Windows 10 has rolled out, I would like to know whether doing the same steps as for Windows 8 would install it. I would wait until somebody else has tried it out and posted it on the internet, but I'm somewhat out of time to wait. Will it be risky trying it out so soon, or does anyone know about what would work?

My computer shipped with Windows 8 and later I upgraded to Windows 8.1 Right now I'm trying to get Windows 8.1 to dual boot with Ubuntu 12.04, but the Grub menu doesn't show up at all. My computer just boots straight to Windows. I searched for this online and the only answer I get is  to edit /etc/default/grub, but I don't even know what this is and where to find this. I also can't use a bootable CD, only a USB. I really need step-by-step answers that aren't confusing like all the other ones I've found so far.  EDIT: I just rebooted and now the Grub menu does show up but when I try to boot into Ubuntu, it says a file is missing. Windows boots normally though. I have disabled secure boot and fast startup.      Windows failed to start. A recent hardware change or software change might be the cause.     To fix the problem:     1. Insert your Windows installation disc and restart your computer.     2. Choose your language settings, and then click "Next."     3. Click "Repair your computer"     If you do not have this disc, contact your computer administrator or computer manufacturer for assistance.     File: \NST\AutoNeoGrub0.mbr     Status: 0xc000007b     Info: The application or operating system couldn't be loaded because a required file is missing or contains errors.   I'm not sure if that file was corrupted while installing Ubuntu or it's missing.

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?

Actually, I have done something terribly wrong. I did not want Ubuntu 13.04 on my PC anymore. I was sick of dual-booting every time the PC starts, and I wanted to return to Windows as well. (My version is Windows XP MCE SP2). The mistake I did is that I simply used EASUS Partition Manager to delete the Ubuntu partitions. But what went wrong here is that, even when I did it, the GRUB keeps trying to load. It says that GRUB could not be found and finally ends up running GRUB Rescue.  I cannot "Repair" my PC using the Recovery Discs (containing Windows XP MCE), it only gives me an option to press "F", which will format the HDD to re-install the OS.  Although, the best part is that I can still log in to Windows. Because, when I boot from the CD's, it does not give me a "Repair" option, but only "Format" and "Quit". By using "Quit", it takes me straight to Windows.  But I do not want to keep doing this same thing every time I start my PC. Neither do I want to Format my Hard Disk. I have tried a few applications, like EasyBCD which do nothing. So I want a good solution for it.  Is their any way to install MBR through Windows or maybe Ubuntu terminal? Even if i can't access Ubuntu again? And what after installing Ubuntu again. Any safe method to uninstall it?

I have installed Ubuntu as another OS on my laptop, and my default OS is Windows 7. I just want to know how to remove (or uninstall) Ubuntu without harming the other OS.  PS: Ubuntu and Windows 7 are both installed on one drive.

I installed Ubuntu 12.04 LTS on a hard drive, and after that on a different partition on the same hard drive with windows7. In both cases, after Ubuntu finished installing, the computer reboots, and it boots automatic into window7, without any boot menu to select the OS. So, How can I make my bootloader to see both windows and Ubuntu?
