Is there any way to reinstall Ubuntu 12.04 straight from the terminal? My terminal works but I literally almost purged my entire operating system by accident (bad advice from a community member). The terminal runs on a black screen now but it works. Any ideas?

I have absolutely no experience with Linux, and I desperately need to get my computer back up and running again with Windows.  How do I remove Ubuntu and reinstall Windows?    Editor's note: many of the answers are about removing Ubuntu from dual-boot but keeping Windows (which is a bit complicated), while other answers are about removing Ubuntu from single-boot (which is easy: basically just format the disk while installing Windows). The question as written is ambiguous between dual-boot or single-boot.

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?

I've upgraded to Ubuntu 12.04 and did it . I didn't look at the "packages to remove" section before clicking next - I've done Ubuntu upgrades many times and assumed it was just the normal set of obsolete library packages etc. But I do tend to watch the terminal text go by and see what it's doing, and I saw it removing a number of packages I wanted. I guess these are packages that aren't on the CD that can't co-exist with the new Ubuntu.  Anyway, I want to find which packages have been removed. So does the update log get saved somewhere?  Then I can start doing some grepping on it and then reinstall the packages I did want.

I'm brand new to Linux. I just installed Ubuntu as a dual boot system on my HP Pavilion laptop.  Where should I start? I've tried to play around with Terminal over the last hour or so, but I'm probably not helping myself out. Any suggestions are welcome!

I just typed   sudo apt-get remove python2.6   I didn't realized that this command will uninstall the whole packages from my computer. Is it possible to uninstall the ubuntu without CD. Or how can I fix this big mistake?

How do you completely remove ubuntu-desktop along with all installed packages with it? I'm using Ubuntu 14.04 server on vps and used sudo apt-get install ubuntu-desktop to install.

I was attempting to update my 11.10 install to 12.04beta. During the install step, I accidentally lost power to my laptop (the power cable came unplugged) and it shut down. Whenever I go to boot now, I can select my install via Grub and it loads up to where the sign-in should happen, but I get a display that looks like what you see as soon as you shut down. It looks like it locks after checking for the battery.   Is there anyway, with or without Live media, to restore my machine's install/update to 12.04 but still keep my settings/applications/files?

I would like to ask a very basic question but I have never thought about it before. Well, when someone installs an application from terminal, he has to add the repository first, right? On the other side, when someone installs an application from the Ubuntu Software Center, is the repository then added automatically?  I am asking those questions to figure out this: When I run update and then upgrade, will this application be upgraded or not? Is the result same in two options?

This is NOT an installation problem question. I've had both op sys working fine side-by-side for a couple of weeks now. I'm using Ubunutu 12.04 64-bit.  This morning when I tried to switch from Win8 to Ubuntu, it just rebooted into Win8. No grub screen whatsoever. This is the 3rd machine I've had dual-booting &amp; have never seen this, but then Win8 is a 1st for me &amp; has thrown some pretty awesome blocks in the path to get to here. Atrocious op sys...  I'm assuming the ASUS updater did this yesterday. (ASUS R503U)  So, do I just put the Ubuntu disk in &amp; reinstall grub?

I just installed Ubuntu 18 on my desktop PC alongside Windows 10 and have been using Ubuntu without any problems for a couple of days. Today, when I booted up my computer, I am no longer able to open the terminal at all. I've tried restarting it multiple times, but it still won't work. If I click the terminal icon on my task bar, nothing happens. If I try opening the terminal with CTRL+ALT+t, it still doesn't work.   How can I resolve this?

How can I safely upgrade an Ubuntu installation from one release to another? What should I do before upgrading to ensure it goes smoothly, and is there any clean-up I need to do afterwards?  In particular, do I need to do anything special if I am using packages from PPAs, if I have a graphics card that needs drivers, or if I'm running a custom Linux kernel?  This is a general question , but as example we take Ubuntu 12.04 and Ubuntu 12.10

Hi I'm new to ubuntu world. I have few questions about the software installation in ubuntu:   What's the difference between installing a software in ubuntu software center and command line? Why some software I installed with command line can't be searched in software center (press the window key)? What are the correct commands to install a software from command line so that I can search them? I backed and restored up my system once but some commands worked before (like "subl") don't work after restoring the system.   I think these questions are about $PATH somehow but I can't find some material about this. Any extra material would be appreciated. :)
