I just got a new pc and installed windows 10 and I am a big linux fan so of course I setup dual boot with ubuntu 15.10 but I would also like to setup linux mint. I have checked out other questions like this but they all start without ubuntu installed. Is it still possible for me to add another distro after I have installed ubuntu?

Triple Booting Xubuntu, Ubuntu and Windows   I'm an avid Xubuntu (Ubuntu + XFCE) user but I also dual boot with Windows XP.  I originally created 3 partitions and wanted to use the empty one as a storage volume but now I want to install Ubuntu 12.04 LTS (the one with Unity) to do advanced testing and packaging. Ideally I would love to keep these two totally separate as I had problems in the past with conflicts between Unity and XFCE.  This way I could wipe the Ubuntu w/ Unity installation if there are problems and really mess around with it.  My disk looks like this:   Disk /dev/sda: 200.0 GB, 200049647616 bytes 255 heads, 63 sectors/track, 24321 cylinders, total 390721968 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes     Device Boot      Start         End      Blocks   Id  System /dev/sda1   *          63    78139454    39069696    7  HPFS/NTFS/exFAT /dev/sda2        78141440   156280831    39069696   83  Linux /dev/sda3       156282878   386533375   115125249    5  Extended /dev/sda4       386533376   390721535     2094080   82  Linux swap / Solaris /dev/sda5       156282880   386533375   115125248   83  Linux   Keep each in it's own partition and totally separate and be able to select from each of the three systems from the GRUB boot menu...  sda1 ---> [Windows XP] sda2 ---> [Ubuntu 12.04] "Unity" sda3(4,5) --> [Xubuntu 12.02] "Primary XFCE"   What is the safest and easiest way to do this without messing my system up and requiring invasive activity?

I have been trying for a week to install (not live cd) Ubuntu on an external drive.  I am totally new to Linux and would love to try it out. That's why I want to install it on an external drive and not dual boot.   I used two USBs, one with a live Linux system, and another to install it onto. I chose the boot location as the external hard drive when installing Linux. But when I boot the PC (without the drive inserted)  GRUB appears and stays there. However when the drive is inserted and I boot the PC GRUB appears and gives me the option to go to Ubuntu.   So it seems as if Ubuntu is installed on the USB, but something important for booting seems to be installed on the PC and therefore when I use the drive on a different PC it doesn't boot (which is the main reason I'm installing Linux).   Please help me fix this!

I went ahead and installed windows 10 on my windows 8 and Ubuntu dual boot PC. All went smooth and Windows 10 works perfectly however the computer automatically boots to Windows and the grub launcher is missing. The partitions are still there I just need some help getting Ubuntu back. Thank you in advance!   Edit: I found a way around it. I don't know of this works for everyone but I went in to the control panel and went to update and recovery. Then I went to recovery and booted into uefi.  Then I selected boot from device and my Ubuntu partition was there and I could boot into it.  Feel free to post other solutions though!

I have installed Ubuntu as another OS on my laptop, and my default OS is Windows 7. I just want to know how to remove (or uninstall) Ubuntu without harming the other OS.  PS: Ubuntu and Windows 7 are both installed on one drive.

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?

Hi I want to try Ubuntu 20.04 without installing it due to some driver issues in my laptop. But I already have 2 OS ( Windows 10 and Ubuntu 20.04 [Dualboot] ), so will trying Ubuntu mess with the already installed Operating systems? And I know how to make live usb and booting from it but don't know how to exit it and then bring my laptop back to normal. Tried finding procedure on internet but reliable results are not found.

I am brand new to Ubuntu. I have just build my new PC, it has 2 separate hard drives installed in it. I would like to install Windows 10 on the first SsD (They are both 250GB Samsung 850 EVO) and i would like to install Ubuntu on the other and be able to choose to use either one or the other on dual boot. As i said I am brand new to Ubuntu. In fact, I have not downloaded or installed it as yet. I would like to know if this dual booting from separate hard drives is possible.

I want to install Ubuntu on my laptop that doesn't have a CD-ROM drive and I have no spare USB disk. I've tried Wubi, but that doesn't seem to work (since it prompts me to have the CD in the drive, which I don't have).  How can I install Ubuntu, easily and in a fast way?  P.s: I want to dual boot it with Windows 7 (which was preinstalled).  Edit:   When extracting the ISO to a folder and running Wubi it does install, but when I reboot the computer, it doesn't show GRUB, nor can I choose if I want to boot Ubuntu or Windows 7. After trying for the third time today, wubi gives me an error: Permission denied   I'm the administrator on the PC.

I recently got a computer from school. It came with Windows 8.1 installed. I then installed another copy of Windows 8.1 (so it would use the built-in Windows Pro license) and upgraded it to Windows 10. I then installed Ubuntu alongside both Windows 8 and 10. Note that I made a separate 255MB ext2 partition for /boot. Now, when I boot the computer, I first see a GRUB prompt (I already un-hid the grub prompt 'cuz I like it that way) with Windows 8 and Ubuntu options. However, there is no Windows 10 option. If I select Ubuntu, the computer boots into Ubuntu. However, if I select the Windows 8 option, I then get sent to the Windows bootloader, where it then gives me options to boot either Windows 8 or Windows 10. (However, by this point, the computer has already loaded the kernel and all. Apparently Microsoft misunderstood the concept of a bootloader and decided that that meant &quot;boot practically the entire system before actually showing the bootloader&quot;. Typical Microsoft.) How can I disable the Windows bootloader and add a Windows 10 option to GRUB? EDIT: Someone has answered telling me to disable the Windows bootloader. However, I still do not know how to add Windows to the GRUB OS list. Can anyone help with this? EDIT 2: After removing Windows 10 from the Windows bootloader with EasyBCD, it seemed that, after a few reboots, it would continually unhide itself and Windows 10 would reappear. However, I then later deleted Windows 10 from the list of OSes in msconfig, and it seems to have stayed deleted. However, I STILL have not managed to get Windows 10 to appear in GRUB. It's as if GRUB simply doesn't detect it. Also, I'll put this in the question so that people see it - I have tried using boot-repair, however, it has NOT helped any.

Im not familiar with Ubuntu or Linux in general but have succesfully installed dual-boot windows7/Ubuntu on a single harddisk on my private PC. I used the "Install Ubuntu alongside them"-option.   On my work PC I have an existing windows 7 64-bit installation that boots from BIOS firmware on a SSD drive (C:), and have my working data (documents etc) on a partition on a separate disk (D:). I now want to install Ubuntu (v 14.04.3) on the remaining unformatted space on D:\ using with the option of choosing system using GRUB. There are of cause fine descriptions around (e.g.  and ). My question is how to setup the partitions in the "something else"- option during the Ubuntu installation.   In  tutorial they assume that all partitions on the D-drive can be deleted; however I only obviously want to keep the working data on the existing D-partition, and place Ubuntu on the residual space (or part of it) on the D:-drive.  A) How is this ensured ? B) how many partitions should I make (boot, root, home, swap ?)  C) and should boot be made primary, and the others logical ? D) Should I set Device for boot loader installation as/dev/sdb - will this not erase the existing D-partion ?

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 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?

I want to install Ubuntu on the C: partition where my Windows 7 is, simply to replace the systems. I've also tried to install it on another partition (without formating it), which failed!  All I get is:      No root file system is defined. Please correct this from the partitioning menu.   I want to install Ubuntu without formatting any of my partitions. Is that possible?

I have a PC with 5 hard drives (SSD and HDD). One of the drives has Windows 10. In the past, I have tried to install Ubuntu and Windows using the following method so there will be no interference between the two operating systems:  I Simply removed all the hard drives, except the one that I wanted to install Ubuntu, then install ubuntu and connect other hard drives. Then select the boot drive using the BIOS.  Can I do the same thing without taking out taking all the drives?  I mean I do not like  to see the GRUB on boot, I want windows to boot as default without the need for GRUB.
