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.

A few months I decided to install Ubuntu 12.04 on my PC alongside with my Windows 7 partition. In order to do that and avoid any mistake, I followed the steps of  tutorial.  Everything was going well until I decided to update to the 12.10 release. I don't know what happened, but after I updated my Ubuntu, it stopped working, it didn't even launched, when I turned on my PC and choose to run "Ubuntu 12.04" on the Grub Screen, a weird messaged appeared.  Well, so I decided to install the Ubuntu 12.10 and forget about the 12.04 partition, no problem.  I erased the partitions used for the Ubuntu 12.04 with EaseUS partition Manager.   However, when I start my PC, there is still the option of "Ubuntu 12.04" to chose, is that bad?  And what about now, can I use the  of Ubuntu to install the Ubuntu 12.10 ? What should I do to have Ubuntu 12.10 and Windows 7 in dual boot again?

I have had the last Ubuntu distro (10.something) installed for a year and love it.  But I have run in to an issue when I tried to upgrade it to the latest one it did not work and there has come some serious issues now with almost everything and I want to remove Ubuntu completely and install the new one.  How can I remove the operating system (I don’t mind formatting the whole thing if that’s what’s needed).

Hello can someone give me short tutorial how to:   Remove Windows 7 from my dual boot system (Ubuntu/Windows7) Let me use free space as new partition for data (so I don't need to extend Ubuntu itself here) Remove windows 7 option from boot screen   Update:  Thanks to Lekensteyn answer I successfully deleted windows. Now I created new partition (formatted to ext4), but I can not use it. I cannot copy files there, only as root.  Also when booting, Ubuntu complains it didn't find /windows partition (of course it didn't, I removed it). I feel like I should update some tables or what, any ideas?

I want to uninstall Ubuntu, so I need to delete its partition.  I saw that many people asked this before. For example: . I followed the instructions there and here's a screenshot of the terminal after typing the suggested command (df):    But this doesn't tell me anything...   This has also been discussed before  and the answer was: EFI and primary. But I have a lot of primary partitions and I'm not sure which one to delete.  Here's a screenshot of Disk Management in Windows:    Here's a GParted screenshot:    So can anybody tell me which the Ubuntu partitions are? (I numbered them from left to right, so to make it easy just tell me numbers please)

I have a computer which is currently running Ubuntu 14.04. I would like to dual boot with Windows 8. I can not find any instructions for installing Windows after Ubuntu is already installed. I am only finding instructions for doing the opposite, Installing Ubuntu after Windows 8.

I am not sure if this question is appropriate to be posted here but I have really no idea and I really need to fix this problem ASAP and I am so frustrated right now. I was dual booting windows 8.1 with ubuntu and after a successful installation in which both OSes boot fine, I installed gnome on Ubuntu and I could not get Ubuntu booting again, so I decided to reinstall Ubuntu but I didn't know that the reinstall and wipe data option will remove the Windows drive. Now I am left with Ubuntu but I still need Windows as my primary OS, I have backup up a system image of Windows 8.1 and my question is how to restore from that, loosing Ubuntu isn't an issue, any ideas would be greatly appreciated

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 had installed Ubuntu to my Dell Inspiron laptop with 3 partitions.   After I installed Windows I was unable to create new partitions, since I already reached the maximum number of partitions.  So I deleted the Ubuntu partitions and I installed Windows on two partitions. So I have got 4 partitions with Windows.  Then I tried to install the Ubuntu that previously deleted(on unallocated space). But the problem is that unallocated partitions are grayed out and can't be used.  Now what can I do?

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 laptop (4 GB RAM, 500 GB HDD, Intel core i3 2.4 GHz) with 2 Partitions: one For data and one for windows 8 x64.  Actually, I want to install Ubuntu 12.10 instead of Windows 8 but keeping Data partition.   So, my question is: There is no matter to use ubuntu with NTFS Windows Partition. Or i should use ext4 partition for good result? Otherwise what you think about multiple partitions for ubuntu installation?  / /home /etc  ...   Any suggestion will be very appreciated
