I have absolutely no experience with Linux, and I desperately need to get my computer back up and running again with Windows.  How do I remove Ubuntu and reinstall Windows?    Editor's note: many of the answers are about removing Ubuntu from dual-boot but keeping Windows (which is a bit complicated), while other answers are about removing Ubuntu from single-boot (which is easy: basically just format the disk while installing Windows). The question as written is ambiguous between dual-boot or single-boot.

I installed Ubuntu on a Dell XPS 13 laptop that had Windows 10 preinstalled on it. I installed it from a USB flash drive on a partition. When I boot my computer I can only boot into Windows 10 and Ubuntu is nowhere to be seen.  If I boot into my USB then I can see that Ubuntu is installed, but I can't get to it from the BIOS boot menu.

I can buy Dell Latitude E7270 through my employer. It will come with Windows, but I would like to install Ubuntu (most likely 14.04). This model does not appear on the list of certified hardware, however. Does anyone know whether I should anticipate any problems with his laptop? Thanks!

So i'm trying to install Ubuntu on my laptop, it seems to work fine until it tries to install grub. I haven't seen progress the past hour and this is the second attempt.  I'm trying to install 13.10, using a Linux Live USB. I don't care about the contents of the laptop.   I've been trying to find instructions about installing grub before starting the installation, hoping that would solve my issues, but I came up empty.  Laptop is 2 years old, it used to run dual-boot windows 7 and Ubuntu. I'm now doing a fresh install of just Ubuntu.  I hope anyone knows how I can find out why it is happening.

I recently have upgraded my PC, my new Motherboard (ASUS M5A99X EVO) uses UEFi instead of the regular MBR option.  I have a Ubuntu 11.10 installation that I did when I had my previous hardware (MSI MS 7267) , Ubuntu alone boots fine, and so does Windows 7, however Windows 7 is using UEFI (GPT) boot whereas Ubuntu is using MBR.  I have my OSs in separate drives, so that GRUB2 wont' get replaced by the Windows Bootloader and viceversa, as I said both OSs boot fine on their own, but to do that I have to disconnect one drive in this case the Ubuntu drive as it prevents Windows from loading.  Now my question is, How can I change/convert Ubuntu's drive so that instead of using MBR it uses GPT and allow Windows to boot?.   Preferably without reinstalling the whole system or lose any data.  And if I were to wipe the drive, How can I install Ubuntu in GPT, UEFI, whatever it is mode?.  I have used gdisk to convert from MBR to GPT, but now Ubuntu can't boot seems like grub just doesn't start.  I have re installed the OS, and the drive is GPT now by default however grup-pc is still being used instead of grub-efi.  How can i make Ubuntu boot from EFI?.

So basically as it stands I have a laptop which has no cd/dvd drive, and I don't have a usb drive.  The laptop has windows 7 installed with ubuntu 11.04 installed through wubi.  What I want to do is remove windows completely, and make ubuntu the only OS installed on the system.  Is there a way to do this without re-installing ubuntu? (i.e. can I take my wubi install away from windows?)  or is there a way to from inside ubuntu have it run the ubuntu iso somehow so I can just wipe the system and install it fresh? (even if it means I need to have an e.g. 2gb partition just for the image to reside in).

I installed windows 10 on my laptop in UEFI mode with HDD GPT disk format, then I installed Ubuntu 16.04LTS on another partition. So I have Ubuntu dualboot with Windows 10 now.  I also installed rEFInd (it's like GUI for you to choose between different OSs) because I don't wanna use Grub2 as the default bootloader. Now I want to have Windows 7 too, but when I boot from the USB stick, an error screen showed up saying something like  the windows boot manager is having problems due to a recent hardware change   My system is still working fine so I don't know if the problem came from my system or if the setup I want is impossible.

I downloaded Ubuntu 12.04 LTS to my Dell Dimension 4600 with Windows XP installed.  I now have a neat dual-boot system, but I want to get rid of the XP OS and keep Ubuntu as my only OS.  How do I do this?

I have a Win/Ubuntu 11.10 dual-boot setup, where I am running the OSes on separate partitions of my laptop HDD. I assume the best method of uninstalling is 'simply' a matter of deleting the Ubuntu partitions -once I've made sure control is given to the Windows bootloader instead of grub after POST.  The question is: How do I do that?  Stuff I've tried:  I tried the boot-repair CD (), but that was a bit beyond my abilities to figure out if I could do it with that tool :/.  I also tried EasyBCD (). It couldn't identify my ext3 partitions, let alone change the bootloader.  Lastly, I tried installing startup-manager in Ubuntu, and using that to set the Win7 bootloader as default. But upon restart, it still loads grub.

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.

I just got a new netbook and I'm setting up operating system configuration. It came with windows 7 starter but I installed dual boot Ubuntu 12.10. I've been writing on some forums and now I don't want things from previous searches and stuff popping up in public so I'm considering a disc wipe and reinstallation of Ubuntu.  Ubuntu was installed by downloading an iso from inside Windows, then put on an usb drive and rebooted and installed alongside windows. I did not do any fancy configuration about swap spaces or partitions. When I start, I get to choose if I want to boot up as Windows or Ubuntu. It automatically chooses Ubuntu. Also, I would like to change this so that it chooses Windows by default.  My question is, is it possible to reinstall Ubuntu without having to reinstall Windows 7?  I'm not interested in a wiping of free disc space or any goverment-level confidentiality. I just want my Ubuntu partition cleared, from occasionaly peeping curious eyes, not having previously visited websites or previously written documents popping up accidentally. If I remove Ubuntu from my hard drive, and then install it again, will a lot of the stuff still be there? I really would like not to format my hard drive because I have stuff on the windows part of the system that I use.

I am using Ubuntu 12.04. I want to install Windows 7 on my system from a CD through VirtualBox. I searched the detailed tutorials through google but I did not find one that worked.   So can some one kindly share any detailed tutorial or link which will really help me out.

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?

Im not familiar with Ubuntu or Linux in general but have succesfully installed dual-boot windows7/Ubuntu on a single harddisk on my private PC. I used the "Install Ubuntu alongside them"-option.   On my work PC I have an existing windows 7 64-bit installation that boots from BIOS firmware on a SSD drive (C:), and have my working data (documents etc) on a partition on a separate disk (D:). I now want to install Ubuntu (v 14.04.3) on the remaining unformatted space on D:\ using with the option of choosing system using GRUB. There are of cause fine descriptions around (e.g.  and ). My question is how to setup the partitions in the "something else"- option during the Ubuntu installation.   In  tutorial they assume that all partitions on the D-drive can be deleted; however I only obviously want to keep the working data on the existing D-partition, and place Ubuntu on the residual space (or part of it) on the D:-drive.  A) How is this ensured ? B) how many partitions should I make (boot, root, home, swap ?)  C) and should boot be made primary, and the others logical ? D) Should I set Device for boot loader installation as/dev/sdb - will this not erase the existing D-partion ?
