Currently, my computer is dual-booting Linux and Windows 7. A series of unfortunate events has led to me needing to restore Windows using a restore disc.  I want to know if this can be done without formatting my entire hard drive, as I don't want to get rid of my Linux partition. That is, I want to reset Windows - which already has a partition on my hard drive - without affecting any of my other partitions on my drive.

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!

I have a laptop with Debian on it, and I am going to sell this laptop.   Would it suffice to erase the Debian installation before selling it to completely clean up my laptop from my personal data, and if yes how can I uninstall Debian (so that there isn't any operating system on the laptop)?

I have Windows 8 pre-installed, and then I installed GRUB with Ubuntu. Ubuntu is not my thing, so now I want to remove it along with GRUB. From what I have learned, with UEFI, GRUB does not overwrite the windows bootloader in the EFI partition and is stored elsewhere. How would I remove GRUB and make my PC use the Windows bootloader instead? It should be noted that I created a separate /boot partition when installing Ubuntu.

I installed Ubuntu 11.10 on a newly bought Lenovo ThinkCentre Edge 71 (model: 1577-G3G) with EFI boot enabled. I opted for the Use Entire Disk option. Even though the installation process went without any problems/errors, when rebooting it now just gives me:     No bootable operating system. Insert bootable disk and press any key...   I figure this is because of EFI.   Regression:   I have checked the System Setup (F1 during POST) to find a BIOS option to disable EFI/UEFI boot, however, there is no such option for this machine. This might be caused by a "Secure Boot" feature in the BIOS. The hardware vendor does not know of any such "secure boot" setting in the BIOS that would prevent Linux from booting. Lenovo support did not know anything about a BIOS setting called secure boot. They also did not know of any limitations that would prevent Linux from booting. The  does not mention EFI, UEFI nor secure boot.   How do I install Ubuntu on a machine with EFI? - Or, since Ubuntu is probably already installed: how do I make it boot Ubuntu?

I've posted a question  that I have a 32bits windows 7 on a dual boot machine with ubuntu 10.04 upgraded to 11.04. From the responses I had from the questions, I decided to reinstall the windows 7 but this time a 64bits version.  I've install the grub on the first section of the HDD on which ubuntu is install, meaning the 2nd Drive.  I still want guidance before I proceed.  What would you suggest me as best way to achieve that without disturbing the boot loading.  thank you for reading this.

I had windows 10 but during a reset, it died ( I know my bad ). So I am attempting to wipe the drive and install ubuntu from a clean install but whenever I select to install ubuntu it only gives me a black screen. It's in UEFI and secure boot.  Can anyone tell me what I'm doing wrong?

I am dual booting Windows 10 and Ubuntu 18.04. How to tell grub not to show the boot menu and boot directly to Windows 10 by default? What should I do if I want to boot to Ubuntu 18.04 instead of the default Windows 10?

According to ,      /data ... Wiping this partition essentially performs a factory reset on your device, restoring it to the way it was when you first booted it, or the way it was after the last official or custom ROM installation. When you perform a wipe data/factory reset from recovery, it is this partition that you are wiping.   What about /boot, /system, and /recovery, and /cache?    If Factory Reset wipes only /data, then I wish it were called something else, because if you've rooted your phone, it will still be left with whatever custom ROM you flashed even after a Factory Reset.    On the other hand, if Factory Reset does indeed wipe /boot, /system, and /recovery as well, especially /boot, what does it restore those from?  Do all phones come with stock images in a real internal ROM somewhere that it can re-flash those images from?    I can somehow imagine manufacturers not wanting be burdened with the extra cost that such a spec for hardware-recoverable images might have cost them, so it got left out of the standard and left out of most phones, which is why it's so easy to brick them.  So, instead, they give you the option to wipe /data and /cache only, and call that a "Factory Reset" because you're not supposed to be foolish enough to root your phone in the first place according to their way of thinking.  Since rooting my Android and reading hundreds of posts, I've found that many of the terms I learned and accepted as a Computer Science grad student in the 80's don't quite mean the same thing anymore so I have to verify what everything really means before I do something.    Comments to  answer the first part of my question.  But they don't really answer the second part of my question which is really a complaint:  Why call it "Factory Reset" if it doesn't really restore your phone to it's stock factory state?    At this point, the question is merely rhetorical.  I think I already answered this in my question, unless someone can correct me.

I want to completely remove Ubuntu from my system. But if I delete the partition, the Grub files will be deleted and that will leave me "Bootloader-less". How can I workaround this?

I need to replace my current motherboard with a new one, no other parts are changed.   Must I format my harddrive and reinstall windows, or can I use the old installation and let windows install the right drivers?  I realize, there might be a performance hit, but I'll probably need the new one just for a week and would like to replace it with the old motherboard again.

I have a problem: today at work I was told that tomorrow afternoon I have to give my pc back and take a new one just arrived. It could be a good new, but I'm a developer and I use a lot of different software to work (Visual Studio, Delphi, Eclipse, Android, Apache, MySql, etc...) and I can't think about starting to reinstall and configure everything... usually it means one week lost... and some data usually get lost too with those migrations... So, is there any way I can use my current disk as system disk on new pc? I'm afraid because motherboard and cpu are completely different...  Is there something I could do to prepare "migration"? Any kind of Sysprep command so when Windows Seven boots start recognizing new devices without getting lost with previous ones?  UPDATE: Perhaps I've just found a suitable solution here:

I recently bought a shiny new Lenovo Yoga 2 Pro and I want to dual boot it with Ubuntu for studying purposes. Its built-in OS is Windows 8.1 and it has a 256GB SSD.  I've made a separate 90GB partition just for Ubuntu and a live USB to install it.  The first time everything seemed to work great, I solved the wifi issued by blacklisting ideapad_laptop, the installation went flawlessly and Ubuntu worked fine.  When I got up the next morning and turned on my laptop it booted into Windows right away without ever showing the GRUB menu. So I tried to reset, and checked my partitions with the Disk Manager and everything looked fine. Since I couldn't find a solution online I went ahead and formatted the partition to try and install again. This time and every time since, the installation was aborted and I got a fatal error saying:  Unable to install GRUB in /dev/sda Executing `grub-install /dev/sda` failed. This is a fatal error.   Can anyone please suggest a solution to this problem? If any further information is needed I would be happy to provide it. Thanks.  When installing I get the following in details:  ubuntu kernel: [ 1946.372741] FAT-fs (sda2): error, fat_get_cluster: invalid cluster chain (i_pos 0). ubuntu grub-installer: error: Running 'grub-install --force failed.

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 use the "reset my PC" feature of Windows 10 to wipe the data on my Windows partition. But I have also a Linux system installed, which I want to keep.  Will Windows 10's full reset wipe all my disk, or just Windows's partitions ?

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.
