    I'd like to have a small partition to have Linux/Ubuntu, and boot to that whenever I would like, but I am a bit afraid that it might somehow screw up the rest of the system - in which case I don't want to take the risk.

      One risk of course is that one of the options is to replace the current OS, thus removing windows. Obviously just make sure you do not choose that option. Other than that you will need to deal with the dual boot every time. I haven't otherwise seen any impact. Have you considered just using virtualization like Docker or VirtualBox?

        I installed Ubuntu on my Windows pc without any problems. Make sure you create a free disk partition in Windows where Ubuntu will be loaded. You may also need to alter the grub settings so that Ubuntu is not started by default on boot.

          Works like a charm for me. This laptop, not only do I have dual boot Ubuntu / Win10, but each OS can access the other's partitions. No need to duplicate files... To make that work smoothly you need two things: ext2fsd so Windows can see your Ubuntu partitions, and you need to turn OFF "fast boot" or whatever it's called in Win10. This is necessary for Win10 to properly close its partitions at shutdown, so they are not flagged as "unclean" when Ubuntu want to mount them. Another thing that makes life easier - set GRUB_DEFAULT=saved and GRUB_SAVEDEFAULT=true (in /etc/default/grub) That means all those involuntary reboots won't get hung up on the wrong side of the fence. Happy dual-booting! Peter [edit] added GRUB_SAVEDEFAULT=true [/edit]

              I tried dual boot and at one point hit an issue where the MBR got corrupted. It took me a bit of sweating and work to fix it(not too much work more sweating and a fair amount of swearing too) and after googling more on the issue I decided to use Virtualbox instead which suited my needs. After my experience with the MBR corruption I would not use dual boot again largely because a VM is so much safer.

                Likely windows has used up the whole disk so you will need to shrink the partition to make space. Windows disk manager can do this, and being from & within windows it's safe. (Third party products can do this too often aloowing better shrinkage, but more risky.) Do this before running the ubuntu installer. The ubuntu installer should handle setting up the dual boot (not used ubuntu myself but others do this). If starting from scratch always install windows first. Most linuxes will set up dual boot if it sees a windows bootable partition, whereas windows won't do it for linux and in some cases may even wipe that 'other' partition's record. (But windows will do dual boot for other windows, what a surprise - they can do it but choose not to when it's not windows.)

                  It should work, but prepare for possible trouble. Make at least a full backup of your data like personal files and photos. Make an extra partition with Windows and try it. Ubuntu is an established system :thumbsup:

                    I have Windows on the C:\ drive, and two different USB-pens with Linux - what gets booted is determined at startup. The only downside was Windows continuously asking whether or not to format the USB-key that contained Linux (being a drive in an unrecognized format).

                      Ubuntu takes care of this and gives you a windows boot option in grub.

                        I know this isn't the answer you're looking for, and others have already pointed it out, but I'll still say it anyway: Once I figured out what virtual machines were all about (roughly a decade ago), I stopped putting myself through the hell that dual triple multi-booting can be and never looked back. Is there a specific reason you don't want your Linux instance virtualized? If you're scared of multi-booting because you don't fully understand its implications and intricacies - VMs are exactly what you should be looking at.

                          Why not Ubuntu on Windows? If you care mostly about the command line, get the best of both word: [Install Ubuntu on Windows 10 | Ubuntu tutorials](https://tutorials.ubuntu.com/tutorial/tutorial-ubuntu-on-windows#0) I think I saw somewhere people experimenting with XWindows (in Linux on Windows), google it...

                            I'm currently dual-booting Kali and windows 10 - the only problems I've run into relate to no sound when I reboot from Kali to win (I need to shut down and power on again - no idea why, and not that much of a drag TBH)..... HOWEVER - be aware the pretty much every time there's a major windows update (such as the April 2018 one recently), windows will probably screw up your boot loader meaning you can't boot either - apparently it's been an issue since the windows 7 days, but MS aren't fixing it - windows assumes it's the only OS and overwrites GRUB.....it's pretty simple to fix, but does require some searching to find the correct incantations lol... If you just want to user Linux, and your processor supports it (most do), then I'd suggest switching on hyper-v and installing to a VM.....or even Windows Subsystem for Linux - not the full smash, but close enough to learn the terminal etc...

                              Everyone else has already covered the issues with installing Linux to an existing windows box, so I've nothing to add other than I've done it for years. However, since I was doing it mostly to keep a Linux image around for fixing windows, another option is to put a live "CD" image of Ubuntu on a flash drive and boot to it when you want Linux -- that's what I do these days.

                              I live in Oregon, and I'm an engineer.
