I installed Ubuntu 12.04 in my laptop. Now I want to remove Ubuntu and I install Windows 7.  But when I restart my system after keeping Windows 7 DVD it is not booting.  What should I do to get rid of this problem?  I have tried to modify many options, but none of them had worked out?

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 need to install Ubuntu instead of Windows 7. Can you tell me the steps to do it? I don't want to install Ubuntu alongside Windows. Any precautions needed before installing Ubuntu? How do I install Ubuntu 11.10 without losing the current data in my laptop?

I have an ASUS K55VM and it came with DOS, and then Windows 7 was installed. I am planning to install Ubuntu on it. My computer had 4 partitions: 240GB, 230GB, 230GB, and 230GB, and I changed this to 5 partitions: 243GB, 230GB, 230GB, 150GB, and 80GB. I installed Ubuntu 12.04 to the 80GB partition through a USB flash drive. It installed fine, however the problem is during the Boot option in Windows Boot Manager. When I choose Ubuntu, this what is displayed:  Windows failed to start. A recent hardware 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 don't have this disc, contact your system administrator or computer manufacturer for assistance.    File: \ubuntu\winboot\wubildr.mbr   Status: 0xc000000e   Info: The selected entry could not be loaded because the application is missing or corrupt.   I tried to change the boot option for the OS and made Ubuntu as my first option. It worked, however Windows 7 does not show up in GRUB. In this fear I did the following:     Restarted my PC changed boot option 1 to Windows.   Formatted the drive to which Ubuntu was installed (80GB one) through Windows.   Restarted again.     The problem persists. Windows Boot Manager still shows Ubuntu, and when I choose this it gives two lines one like: grub rescue&gt;, but my Windows 7 is working perfectly fine.  Now I want a solution to remove Ubuntu from the Windows boot option and reinstall completely.

I booted from the Ubuntu ISO which I burned on a disk and installed Ubuntu, and chose the option to replace windows 7 with Ubuntu, now the version of windows 7 I was running was an illegal cracked version and I already had tried to get rid of it without booting into the actual OS and after many attempts was unsuccessful. Now did installing Ubuntu and choosing the option of replacing windows 7 actually solve my problem and did it wipe the previous windows OS EVERY LITTLE PART OF IT.

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?

I recently purchased an ASUS N56VZ-ES71 laptop which came with Windows 7 Home Premium installed on it. I wish to dual boot Windows 7 and Ubuntu 12.04 on it. I shrank the hard drive partitions to leave about 150 GB unallocated for Ubuntu 12.04. When I boot the Live CD of Ubuntu and attempt to install, the installer does not recognize any other operating systems. Through reading a few questions, I have found that this is due to a GPT partitioning table that Windows uses.  I ran boot-repair as per other threads' suggestions. This was my output:   I suppose my question is: how do I proceed in order to get the installer to recognize Windows, so that I don't have to erase the current partition table and can get a safe install?  Thanks in advance.

I have two systems installed previously Windows 7 and Ubuntu. I was trying to reinstall Ubuntu and format the Ubuntu OS partition using a tool in Windows 7.   When I have Ubuntu ready on a USB stick and restart my laptop, it prompts me with the GRUB rescue screen. If I boot from USB to install Ubuntu, it just hangs.   Anyway, I messed up everything. So my question is how can I boot Windows 7 now?

For some reason I can't install Ubuntu from CD or USB, so that I had to installed Ubuntu via Wubi. But I install Ubuntu into partition 'D' and partition of Win 7 is 'C'. If I re-install win 7, how can I use pre-installed Ubuntu ?

I have Windows 7 installed in my internal HDD and wanted to try out Ubuntu so I have an USB to put Ubuntu LiveUSB on and installed Ubuntu on a external HDD and everything worked out fine.  Now the problem. If I remove the external HDD and try to boot Windows normally it shows the grub rescue screen. The only way to boot into Windows is by having the external HDD attached.  Is there any way I can make it so I won't have to have the external HDD attached to be able to boot my Windows 7?

I currently have Windows 7 on my computer and I want to install Ubuntu alongside Windows safely.  Could someone please provide clear instructions?

I am just about to install Ubuntu alongside Windows, just need to make sure I know how to remove it later.  I know from past the major problem was when I removed Ubuntu, I either still got into the GRUB booting menu, or I couldn't boot at all, and had to format HDD and start over. Now I found an article practically saying the Windows loader should be back upon deleting Linux partition, so I want to make sure:  If I have Windows and Ubuntu dualboot, and I want to get back to Windows booting quickly itself without choosing from any booting menu, is it enough to just delete the Ubuntu partition? Will the Windows loader override GRUB?  Thanks!
