How to run Ubuntu alongside Windows?

So basically, I bought an Ubuntu laptop (because of cheaper) and installed Win10 on its place. Now I rang support and they said I need the original OS to get support. Can somebody just tell quickly how to run Ubuntu alongside Windows?

 

Create a second partition without a file system. Install Ubuntu into that partition and add Windows 10 to the bootloader (actually it should do that automatically).
There are plenty of wiki/howto articles about that sort of stuff, so run a search if you want details, I don't think this is the appropriate place to discuss this.

The main question is: why did you call for support? was it for hw issues? in that case the OS shouldn't matter (tell them that).
If it was about win10 issues, then installing Ubuntu won't help you anyway.

 

It is a HW issue, but since their bad will won't seem to end before I install the original OS, I figured it's easier to do that than try to explain it to them.

 

What they will give you in support, most likely will then be aimed at the original OS the device came with: Linux.

HW issue, you say, but not what it is. Could be that W10 is causing the issue, its not really unknown to do that... The whole W10 thing is a single monolithic "issue."

You can alternatively try this: google for one of ther many guides telling you how to install a bootable Linux Ubuntu version on a USB stick and then launch the device with this USB stick. You need an Ubuntu ISO for that, and a tool that creates bootable USB sticks. You then boot and end up in Linux and have no messed up boot manager written on your HD, there is a risk that a wrong selection of options leads to this and sees you ending up with a device where you cannot load your wanted OS anymore, repairjng the boot manager is possible then, but tricky if the person doing it is new to the whole stuff. Once you booted into Linux via the stick, check the hardware whether your issue is present under Linux as well, if not, then you know it is a W10 problem. Maybe you will need to play around with different graphcis drivers before your Linux runs stable again, this can happen to be needed.

 

It's actually a simple issue: I bought a laptop and the actual hardware specs are different from the ones announced at their website, so I called their support and (not sure if trying to avoid responsibility or just eliminate every variable) they said I need the original OS to get support. Quite a lot of BS, since OS won't change my CPU clock, but if it's one less way for them to stall my support then I'll just do it. I just don't want to have to erase all my Windows files to do it, so I'll probably create a small partition just for Ubuntu, and if they finally decide to take the product back I'll just leave only the Ubuntu install to make them happy.

 

Yep, linux-stick, best way to go, i would say. I always have a linux-stick by my side, if someone calls out "hardware-issue".
For devices with pre-installed OS: always install your OS of choice alongside - going Dualboot for a lttle while; if everything runs fine, you can still delete the unwanted OS later.

Dont know, but since your profile says brazil - you may find some info over there -> http://ubuntuforum-br.org/ .

edit
Sounds like they only want to get out of the warranty somehow. Never had something like this...

Edit2
But aren't you going to "lose" your win-install, if you have to send it in or get it replaced or something?

 

Does sound suspiciously like it. But let's see, on monday I'll get back to them with the new-old OS, and if they open up their excuse book again I'll just ring some consumer protection service.

 

I do not know the laws in Brazil, but in Germany, if the advertised hardware specs do not meet those of the hardware you got, it would not matter what OS is installed, the fault is theirs and they could be legally held accountable for it. We call it "irreführende Werbung" in German (§5 UWG). This includes not de facto wriong info and wrong statements given about a product - already formulating it in a fashion that could easily be misunderstood by people and could raise misleading impressions, is something the seller could be held accountable for. Compare what you have to that in Brazilian laws. I think what I just described for Germany, indeed is Europe-wide EU law.

Consider to meet your consumer rights organisation immediately.

If the info said for example it is an i7 CPU, but you get only an i5, then it does not matter what you did with the original OS anymore. It does not change the fact that you were misinformed by them - and that is the point, becasue you formed your decision to buy on the basis of this erratic info.
