I run a dualboot with ubuntu 14.04 and windows 8.1. I messed up the ubuntu and now I'm going to install elementary OS instead of ubuntu. I wounder how I should do it in the easiest way possible without mess upp something. Should I first just delete the partition where I have ubuntu on and then create a new partition in windows and on that new partition install elementary OS?
Or can I install elementary distro over the current ubuntu distro and that partition with ubuntu will be overwritten with the installation of elementary OS? So the partition will be like a clean partition with just elementary on it instead of ubuntu? I mean this would be possible if I were to reinstall ubuntu right? So is it possible when I choose to install another distro?
If I had to remove the partition at first will that give some problem to start windows then? I mean I know have a "bootmeny" in grub where I can choose either windows or ubuntu from. But windows have it's own so that problem shouldn't occour? Is there anything else that can go wrong if I remove the partition with ubuntu on?
//UPDATE//
I booted Elementary OS and run the alternative delete ubuntu and install Elementary. The install failed. It said it couldn't install a grub file. Tried to restart the computer but it didn't work to shut down, restart or log off so I were forced to a power button shutdown. When I restart I get like a terminal with GRUV> and then you can write commands wich are listed on the screen when you tab but I don't now what to write?
It is possible to boot into windows pressing F1/F12 and accesing windows boot.
I see three choices: 1.delete the linux mess partitions, but I don't now what partitions windows 8.1 and my computer use by default? How can I figure that out?
2.write some command in grub for something I don't know.
3.find another distro and install that ontop of a messed ubuntu and a messed elementary os.
My laptop is an Lenovo g510 i7 4700MQ with preinstalled windows 8. Sugestions?
//UPDATE2// How do I completely remove grub? I decided to go with linux mint instead but when i choose to boot from the usb with linux mint done with unetbootin. I don't have a choice to install it I can just test it. And when I get to the advanced startup I can choose to boot from usb, cd and so on and I also have an alternative called Ubuntu? What? So I guess remove grub atached to some minimal ubuntu garbage left over will be the call?
