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?

  • @karel - Do you know if that is really the answer? that is; is that bug still active in 16.04? should the first option be avoided and manual used instead? –  Feb 21 '17 at 10:33
  • A fix for bug #1265192 was released for 14.04. – karel Feb 21 '17 at 10:50
  • @karel - you should post that info as answer under the question that you linked here. Otherwise the standing answer is not a good answer for my question here; before that, it is not true that "This question may already have an answer here etc and therefore this is not a duplicate. That is 14.04 this is 16.04 question. –  Feb 21 '17 at 10:53

    Best practice would be to backup for safety regardless. A power failure or hardware failure can lead to unintended consequences even with tried and true solutions. – Elder Geek Feb 22 '17 at 18:48

The Erase Ubuntu and reinstall option in the Installation type screen of the Ubuntu installer will erase Ubuntu and reinstall it over the existing Ubuntu partitions without overwriting Windows if Windows is installed alongside Ubuntu.

enter image description here

This was reported as a critical bug in Ubuntu 13.10: Install/reinstall wipes out all/other partitions and a fix for this bug was released in the Ubuntu 14.04.2 point release.

  • I have to test it myself to be sure, it's too risky and when a bug arrives it's too late. –  Feb 21 '17 at 11:19

Personally I choose "Something else" part and format my main Ubuntu partition and install on that partition, never see an error after that.

It shouldn't pose any problems, but just in case the best would be for you to backup your disc. In this blogpost there's a how to guide for cloning your hard drive using the Ubuntu live cd. Whenever you are playing with partitions you have to be careful.
