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?

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 installed Ubuntu sometime back along side Vista, but later found that I rarely (if ever) use Ubuntu. How easy is it to return my computer to its initial state of having only one OS, and freeing up the hard-drive space used by the Ubuntu install?

Long story short, I installed ubuntu while I was watching netflix and feeling very lazy, and may have lost all my windows 7 files.  Quick summary:    -Windows 7 was installed on Legacy bios and I installed ubuntu on UEFI bios -ubuntu installer didn't detect any other OS on my computer and wanted to write over the disk, so I had to manually edit the partition    -Despite repeated warnings about partitioning windows in the ubuntu installer, I did this anyway, assigning 140 gigs to ubuntu and 500 to windows Now, my computer won't boot into anything but Ubuntu  -in Gparted, it still shows that I have two partitions, and windows 7 boot loader -However, I can't boot into the non-linux partition, and boot loader says I need a recovery disk.  My question is does anyone know if what I've done is fixable? I'm hoping that I can fix it using the way outlined in this thread:   Thanks for the help everyone!  Note: gparted shows:    Foudn linux image: /boot/vmlinuz - 3.13.0.30 - generic   Found linitrd image: /boot/initrd.img - 3.13.0 - 30 - generic   Found linux image: /boot/vmlinuz - 3.13.0 - 24 generic   Found  initrd image: /boot/initrd.img - 3.13.0 - 24- generic   memtest   memtest   Found windows 7 (loader) on /dev/sda1

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 a computer that dual-boots (or tri-boots) Windows 8 Release Preview, Windows 7, and Ubuntu 12.04. Grub boots between Windows 8 and Ubuntu; for which I use primarily. Recently, I decided to remove Ubuntu, as I hardly used it. I deleted the Ubuntu partition accidentally before replacing the Grub bootloader. Now, whenever I want to boot the machine, it gives me the "grub-rescue" prompt -- I am unable to boot into either Windows (8 nor 7), nor Ubuntu (except via USB, of course). I do not have any Windows 7/8 recovery media, so that isn't an option. Please note that after I deleted the Ubuntu partition, I put the PC into hibernate, and then turned it on. This means the C:\ [Windows 8] drive cannot be mounted. I don't know if that is bad, but it definitely doesn't make things better.  I am currently booting Ubuntu via USB, in an effort to restore the Windows bootloader. I have looked into using boot-repair to solve the problem using the instructions , although after attempting to apply the changes, it gave the error: "Please install the [mbr] packages. Then try again." I don't know why I'm getting this error; is there a way to install the 'mbr packages?' I honestly don't know what exactly they are, nor how to install them. Are there any other options I have not yet exhausted to be able to boot back into Windows, in the case that there is a better way? I want to set the bootloader to boot into Windows 8, but booting into either Windows 7 or 8 is fine (I can use EasyBCD from there). Is there a simple solution to this? I've checked BIOS, and I haven't been able to find a way to boot into Windows.

I have Dell Laptop that is 15 5567 7th Generation. So it was maybe pre-installed as Dell says and I can see in the product information that this laptop is Ubuntu built in and based not Windows.  So I want to get my Ubuntu OS again. How can I do that?

I have a PC with Ubuntu and Windows 7. Now I am intending to remove Ubuntu from there. If I login from Windows and use a Partition tool to delete Ubuntu and reclaim its space, I am afraid it would affect booting because boot menu is GRUB.   How would one take care of the same? I do not have a Windows media because it came installed with the PC.

I have dual boot configured with Windows 7 (32bit) and Ubuntu 12.04(64bit). I installed Ubuntu after windows, now my windows is corrupt due to some virus and I need to reinstall it. Currently when I start my PC, grub loader comes up and I need to select Ubuntu or Windows.   I was wondering how can I install windows again and still have my Ubuntu install? Is there a way to do this?  I do not want to install Ubuntu again and lose my settings and data there.   Thanks, Ketan

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?

How do I access the recovery mode in Ubuntu 18.04? I don't see any form of grub bootloader when the system boots - it just goes straight into the OS.

I use both Ubuntu and Windows XP. One thing that catches my attention for a long time is the high need for reboots in Windows. Most of the time when I install a program, Windows requests to reboot system. This happens considerably more frequently than Linux.  Why is it so?  Thanks!

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'm dual booting W7 and Ubuntu (installed from Wubi). I've had it up and running a few times but today I'm getting a message from Windows Boot Manager when I select Ubuntu that wubildr.mbr is missing or corrupt. Any help would be greatly appreciated.

I have 3 partitions: one for Windows 7 (ntfs), one for Ubuntu (ext4) and one just for data (ntfs so both operating systems can see them).  My problem is that I had stored some files on the data partition using Ubuntu and when I booted Windows 7 all that data was gone! After that I couldn't find the files even when using Ubuntu.  My files were simply GONE :(  Is there something I can do in Ubuntu or is it just windows problem?

I have a dual boot system with Ubuntu 16.04 and Windows 7. Windows 7 is automatically booted (default in the bootloader). On both OS I have TeamViewer installed.  When I'm working remotely and want to switch to Ubuntu I have to reboot the PC but then automatically Windows is booted again (I'm not in front of the PC, so I cannot use the bootloader). How can I in such a case switch to Ubuntu, i.e. starting Ubuntu? And how can I switch back to Windows?

I have Windows 7 installed in my PC. In a failed attempt to create a partition my disk has been converted to dynamic including system and boot volumes. How can I install Ubuntu in a partition without affecting the Windows system?
