I am upgrading my fathers computer that has Ubuntu on it, however he wants to keep Ubuntu as an operating system, I heard of dual boot and thought it would be worth a try, however I can't back up the data because most of it is password protected and he forgets his password. Is there any way I could try and add windows 7 onto the Ubuntu desktop without having to take Ubuntu off first, or deleting all the information on the computer if I put windows 7 and it then takes priority. I'm not sure how much of that made sense, but if anyone knows another method of dual booting windows 7 and Ubuntu that would be greatly appreciated.
I have Ubuntu on my laptop. Now I want install Windows 7 in a dual-boot. How can I do this? I can't lose my Ubuntu files, and I'm afraid that I might break . Go  for UEFI only!
I just realized I can't unrar .rar files on my Ubuntu machine!  What's the easiest way to accomplish this fundamental task? If possible I'd love something like 7Zip that I can just right Click, and extract and have the program worry about how to do it regardless if it's a .zip, a .rar or a .foo compressed file. How do I transfer a Gmail account to a different Google account? Validate decimal numbers in JavaScript - IsNumeric() To better describe the above problem, whenever I start up my Ubuntu/Windows 10 Machine and select Ubuntu, whenever the machine tries to start the GNOME Desktop Environment, it says it started it successfully. however, I never get a graphical desktop environment to use. I can fix this by logging into tty3 and typing gnome-session but I don't really want to do that as, for some reason, that skips login. Can anyone help? Where can I install ubuntu if I have 4 primary partitions? I want to triple boot Windows 7, Backtrack, and Ubuntu. Windows and Backtrack are already installed. The problem is that both of them take 4 partitions: 3 for Windows, and 1 for Backtrack. When I try to make another partition, it says I can't have over 4. How can I install Ubuntu with this problem? Note: The 3 Windows partitions are PQSERVICE, SYSTEM RESERVED, and eMachines. I don't really know if I can delete one. Tikz: setting options for pin I just found the pin option to drawing, and it looks useful in some of the things I want to draw. How do I format it though? I've tried pin=[red]60:{Hey!} and I get the error Cannot parse this coordinate.  \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{shapes,arrows,positioning} \begin{document} \begin{tikzpicture}[node distance=2cm,&gt;=latex, every node/.style={     font=\sffamily\scriptsize     },       circtext/.style={draw,circle,minimum size=8pt,inner sep=2pt},     dot/.style={draw,circle,fill=black,minimum size=0.6mm,inner sep=0pt} ] { \node[rectangle, fill=green!10!white!90!black, minimum width=6cm, minimum height=3cm] at (2,0){}; \node[circtext, fill=yellow](A) at (0,0) {A}; \node[circtext, fill=yellow, right=of A](B){B}; \draw[-&gt;] (A) -- node[dot, pos=0.5, pin=[red]60:{Hey!}](C){}(B); } \end{tikzpicture} \end{document}     The default style looks like it's a gray thin arrow, and I want to change it to a black thin dotted line with no arrow.    update: I figured out how to add style to the pin node:  pin={[red]60:Hey!}]  But I can't figure out how to change the linestyle though.
