Currently I have Ubuntu 14.04 LTS installed on my PC, but unfortunately there are some programs, which do not run on Ubuntu even with Wine and there are no good alternatives available.  Therefore I want to additionally install Windows now. This [ article and many others recommend to first install Windows and then Ubuntu, an option that I do not have unless I can somehow back-up and transfer this current system.  It speaks of some advantages to virtualizing the other OS, but due to lack of knowledge, I do not really know what that means and what would be the best option in my case.  I plan to use Ubuntu 95% of the time and Windows only for few programs, that don't run on Ubuntu.  What do you recommend and how do I go about it?  Best regards and thanks for any advice!  Markus

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 am trying to install a fresh version of Ubuntu in my computer without touching the windows 10 dual boot! In the Installation Type, the first option seems exactly what i wanted to do.  My question is, is this feature is safe to use? because i don't want to lose any windows files and other NTFS partitions on the hard-disk. Please eliminate my confusion. Note as that i dont need any files or media which are in the ubuntu partition, Thanks.

I plan on installing Ubuntu 19.04 and give it 100 GB of my 256 GB SSD space and leave the rest for Windows as I would primarily be using Ubuntu.     A. Now, as I plan to install a lot of applications in Ubuntu, should I give more space to the / partition than the home partition? (Or maybe even drop the /home altogether?).    B. I have another 128 GB SD card for files like photos, audio and video files. Please suggest me the optimal partitioning for the use case.    C. Also, I have 8 GB of RAM so what should be the optimal swap partition size?    D. How would the distribution be if I choose "install Ubuntu alongside Windows" option?

I currently have dual boot Windows 8 and Ubuntu 13.04 on a Dell XPS 13 laptop. Ubuntu has a major problem with display drivers (screen backlight) that I haven't been able to solve, so I'm looking for alternatives. I would like to use some kind of virtual machine program on Windows that will boot up my existing Linux install into a fullscreen window. I am after one of two scenarios:  Something that would mount and boot my existing Linux install from where it is, so I can still dual-boot if required. This seems like the cleanest option, and would make life very simple indeed.  A way to make a copy of EVERYTHING from my existing Ubuntu install onto a virtual machine, leaving me free to delete the Linux partitions, and use Ubuntu via VM only.   Scenario 1 is preferred. Thanks for your help.

Hello, as a freelance developer I recently found myself severely bound by the memory limit of 32-bit operating systems, and I need to upgrade to a 64-bit system in order to continue working effectively. (To explain: I have to use multiple virtual machines on a daily basis. Right now I have to turn them on/off frequently as I test solutions, and still my main OS is very slow and swapping heavily.)  I planned to migrate from Windows to GNU/Linux for a very long time, and I'd like to use this opportunity to make the switch now. I will still need to keep Windows around (for games, and as a general fall-back scenario), and since I do not want to dual-boot, I would rather like to run it as a virtualized client OS.  What I would like to achieve:   Primary OS - GNU/Linux (64b)   daily work, web browsing, etc several virtualized client OS' via VirtualBox (for testing applications)&nbsp;  Secondary OS - Windows XP (32b) or Windows 7 (64b)   legacy applications (until I find suitable GNU/Linux alternatives) DRM-ed stuff which works problematically under GNU/Linux (e.g. Blu-ray) games which don't have a native Linux client    Notes:   my hardware supports  to assist the virtualization effort I'm not against a bare metal hypervisor (Xen?) nor against using the primary OS as the host (KVM?), as long as it's possible to make it work (sort of) reliably the secondary OS (Windows) must be able to fully use the graphics/audio hardware (3D video games, i.e. OpenGL/OpenAL, DirectX, etc)   I was already looking into several solutions myself, but I did not manage to find reasonable results (mostly on the bit about games). As I don't have any practical experience with this, I would like to kindly ask you guys for your help before I start the migration effort (and hit a road block).  Which solution would you recommend please? (Is the above possible at all?)   Thank you for your help, M.

I am already dual booting windows 10 with Linux Mint, and I am trying to replace Mint with Ubuntu. I have already created a bootable usb for Ubuntu.  When I try to install Ubuntu, I don't see any option to install Ubuntu alongside windows 10. Rather, I see "install Ubuntu alongside Linux Mint". I didn't find any option to keep my windows 10. How can I replace Mint with Ubuntu in this dual boot system? Mint is installed on an ext4 partition and I have a Linux swap partition.

I have Ubuntu installed on my work computer. I am wondering whether I could have access to it from another computer with Windows installed. If so, could you give a step by step guide?

Having some issues installing Ubuntu 14.04.3 LTS 64bit next to Windows 10.  This is what I did:  1) Created a bootable usb with ubuntu on it using Universal-USB-Installer-1.9.6.3  2) Changed the boot mode  3) Boot from USB - It showed the option to test drive or install - I chose install  4) Choose Language  5) Setup Wireless - I didn't choose anything here  6) Then it showed me the preparing to install  7) After that a message popped up saying:      Unmount partitions that are in use The installer has detected that the following discs have mounted partitions /dev/scd Do you want the   installer to try and unmount these partitions before continuing? If   you leave them mounted, you will not be able to create, delete, resize   partitions on these discs, but you may be able to install on an   existing partition there.   So obviously I said yes.  8) Installation type - I chose something else - This looked nothing like the screen shots I saw on the installation guide.    9) Then it only gave me the option to choose my bootable usb for the installation. With a bunch of options to choose, so I got scared and quit.     Can any one please help?  Keep in my mind I do not know a lot, so please dumb it down. Why can't I choose to run it along side Windows 10? Why doesn't the installation pick up my hard drives?  If you need any other info, please ask. But I think I put everything in here.

What's the difference between installing Linux alongside Windows and installing it on a separate partition?  I already have data on Windows and other partitions that I don't want to lose.

I have 2 partitions (Windows and Ubuntu 13.04) and I am asked which one to boot each time I turn on my computer.  I want to install Ubuntu 13.10 to the entire disk.  I do not mind if all previous Ubuntu/Win data are lost.  How can I do that?

Today I bought a Lenovo G510 Laptop (4GB Ram, 500GB Hard Drive) and need install both Ubuntu and Windows 7. I have some questions regarding this.   What OS should I install first ? What are the partition sizes should I put for swap, root and home ?

I want to know if I will keep and still be able to use my Windows 7 installation after I use the Wubi Windows Installer (from ) to install Ubuntu?  Thanks in advance, Bas.

Just as the question says, I need to install newer version of Ubuntu without messing up the older version. I have looked at the responses to similar questions but it isn't clear to me how to do so (some suggest dual boot using a second hdd and some suggest using virtualization -- both of these are not an option for me).

I'm wanting to use Xen Hypervisor to be able to run both Ubuntu 12.04 and Windows 7 at the same time using virtualization. I can find plenty of XCP tutorials but I'm not looking to install the cloud stack, I just want the server confined to my machine.  All I need is a link to a decent tutorial for this purpose. I've read a ton of articles that lead me to believe I'm on the right track, but not enough to feel comfortable getting it right if I just dive in. I'm getting caught up on whether I need to install Ubuntu and then install Xen into it, or do I need to install Xen on a small partition and then leave the rest of the hard drive open for the virtualization... I dunno.  Basically, I need the virtualization of Windows 7 for Adobe Premiere and After Effects (until Lightworks for Linux comes out and I can afford NUKEX). If I didn't need those, I'd be rocking out a straight up Ubuntu machine or just using VirtualBox for my virtualization. However, I need Windows to run as an HVM so it runs like I would expect rather than having the issues I may run into with VirtualBox (video drivers, etc).  So, any suggestions?

I have already dual systems : Windows 7 and Ubuntu installed on my laptop. The Windows 7 had been installed when I bought this laptop, and I don't have a CD.  I just installed VitrualBox under Ubuntu, hoping that I could install another Windows in this virtual machine, so that I could run some applications of Windows even under Ubuntu.  But it seems that I need a CD or ISO of Windows to boot inside this virtual machine. Otherwise, there is an error: FATAL: No bootable medium found! System halted. My question is where I could find a CD or ISO?  At the moment, I am downloading ISO from this , but do not know if it will work. By the way, I am not sure if I should pick the 32-bit or 64-bit? As my CPU is 64-bit but my Ubuntu is i386.  Could anyone help? Thank you very much.

I want to install a new Ubuntu on a drive where a previous Ubuntu system is already installed beside Windows7.  The first option says that only Ubuntu will be replaced.   The second says that all will be erased.  I only want Ubuntu replaced with the  new one while keeping Windows7 untouched.  Is the first option (“Erase Ubuntu16.10 and reinstall”) the good one in this case?

The only reason I ever boot into Windows (7) is to use the popular video chat software ooVoo (). It's useless under Wine and there seems to be no way to run it in Ubuntu except for some proprietary tools. Does anyone have any information on some alternatives to running it with Wine?
