How can I delete/uninstall ubuntu from single boot laptop and install Windows 8.1? I have tried to do some responses posted before but coudln't make it.
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.
Is voltage the speed of electrons? What book would you recommend for scientists who are not statisticians?  Clear delivery is most appreciated. As well as the explanation of the appropriate techniques and methods for typical tasks: time series analysis, presentation and aggregation of large data sets. Multi-partition multi OS bootable USB I want to create a recovery flash drive. I have my 8 gb flash drive[Kingston data traveller] with me. I also have the required .iso files for a>Ubuntu 13.10 b>Boot-repair disk c>AVG Rescue CD  I Wish to create 4 partitions(3 for each bootable .iso and one for data storage. Also, I want a way in which I can select which OS to boot each time I boot from USB.   So, is there a way to install GRUB on USB as well as the three other live distros? And how to create such a setup? How to create a DEB file manually? I want to create a DEB file manually. I would like to just provide a folder which contains data to install, and a script to be executed after installation.  Is this possible? Identify $P(2014)$ if $P(i)=1/i$ for every positive integer $1\le i\le2013$ Suppose $P(x)$ is a polynomial of degree $2012$ and $P(x) = 1/x$ when $x$ takes the integer values $1\cdots2013$ (inclusive). What is the value of $P(2014)$?   I get $1/1007$ but I'm not sure if it's right, and my method is very inelegant. Let a,b,c be positive real number, such that  $\frac{1}{a}+\frac{1}{b}+\frac{1}{c}=a+b+c$. Prove that :  $\frac{1}{(2a+b+c)^2}+\frac{1}{(2b+c+a)^2}+\frac{1}{(2c+a+b)^2} \leq \frac{3}{16}$  Can anyone help me how to deal with it? Javascript profanity match NOT replace How do you use Excel server-side? A client wants to "Web-enable" a spreadsheet calculation -- the user to specify the values of certain cells, then show them the resulting values in other cells.  (They do NOT want to show the user a "spreadsheet-like" interface. This is not a UI question.)  They have a huge spreadsheet with lots of calculations over many, many sheets.  But, in the end, only two things matter -- (1) you put numbers in a couple cells on one sheet, and (2) you get corresponding numbers off a couple cells in another sheet.  The rest of it is a black box.  I want to present a UI to the user to enter the numbers they want, then I'd like to programatically open the Excel file, set the numbers, tell it to re-calc, and read the result out.  Is this possible/advisable?  Is there a commercial component that makes this easier?  Are their pitfalls I'm not considering?  (I know I can use Office Automation to do this, but I know it's not recommended to do that server-side, since it tries to run in the context of a user, etc.)  A lot of people are saying I need to recreate the formulas in code.  However, this would be staggeringly complex.

What's the definition of a symmetric distribution? Someone told me that a random variable $X$ came from a symmetric distribution if and only if $X$ and $-X$ has the same distribution. But I think this definition is partly true. Because I can present a counterexample $X\sim N(\mu,\sigma^{2})$ and $\mu\neq0$.  Obviously, it has a symmetric distribution, but $X$ and $-X$ have different distribution! Am I right? Do you guys ever think about this question? What's the exact definition of symmetric distribution? String formatting in Python I want to do something like String.Format("[{0}, {1}, {2}]", 1, 2, 3) which returns:  [1, 2, 3]   How do I do this in Python? "Where" exactly are complex numbers used "in the real world"? Migrating to full Ubuntu after dual installation on WinXP I previously ran 12.04 alongside WinXP to see how it performed on my mom's older laptop.  i also migrated her email to Thunderbird. If I now convert from dual WinXP/Ubuntu to only run Ubuntu will things like her Thunderbird emails be transferred as part of the Ubuntu full install? Or must I do something else? I am fairly tech aware, but not a full IT boffin! parsing NSJSONReadingAllowFragments Questions like:   ♦ ♦-should-discriminate-more-when-bumping-unanswered-questions ≠-users-who-want-to-write-good-posts   well, you can see there.  The diamond (and other problematic Unicode characters) in the title breaks the automatic prettification of internal question links.  This becomes a bit more of an issue when one wants to link to an answer.  For example ♦-break-the-automatic-hyperlink-parser/242572#242572 should link to Martijn's answer, but, it doesn't (tangent, but a different issue is that  which is the share link doesn't auto-prettify unless the userid part is removed - one keeps having to manually remove things to get the auto prettify to engage).  If one looks at the html generated for  for the title and the url linked in the &lt;h1&gt; of the page, we get:  &lt;title&gt;Users who can&amp;#39;t write good posts ≠ users who want to write good posts - Meta Stack Exchange&lt;/title&gt;     &lt;h1 itemprop="name"&gt; &lt;a href="/questions/238644/users-who-cant-write-good-posts-%e2%89%a0-users-who-want-to-write-good-posts" class="question-hyperlink"&gt;Users who can&amp;#39;t write good posts ≠ users who want to write good posts&lt;/a&gt; &lt;/h1&gt;   And while that's a long link title, I will point out that the quote as part of the word "can't" was removed from the slug.  The bug is that this should be done for other characters too. Selecting LiDAR return point type in LiDAR dataset with ArcPy? I am trying to create a Digital Earth Model (DEM) using ArcPy under ArcGIS Pro 2, but I am running into some problems.   I can generate a DEM within ArcGIS Pro by selecting only the ground points under LAS files in the LAS dataset properties, but when I try to run the same code within ArcPy, it generates a DEM using all the points.   Any ideas how you select the return point type in ArcPy?   Here is the code that I have used.  arcpy.conversion.LasDatasetToRaster(lasd, "Test_arcpy_dem", "ELEVATION", "BINNING AVERAGE LINEAR", "FLOAT", "CELLSIZE", 10, 1)   As I said, this generates two different outputs, depending if I am in ArcGIS Pro or not. Word for a person who continually tries to teach you when it's not necessary I've experienced this way too many times, and the best example I can give is a person who treats you like you have no idea how to do X and who keeps teaching you how to do it. I feel handicapped. Take for example how to play a card game. You know how to play the game because you've played it 5 times. However, there is a person always insists on explaining the game to you - like you are always new to the game - when you don't actually need any help and you just want to think for yourself. Another example situation is doing a repetitive task which you already have experience with, and yet the person continually tries to 'teach' you when you don't need help/already know how to do it. It almost makes you mad because you really don't need help. As an example which recently happened to me:  &quot;Hey, do you remember how to start the wood chipper?&quot; &quot;Yes I do&quot; &quot;Okay, well, let me show you one more time&quot;  Again, is there a term for someone who does this? Where can you find the quantities of each amino acid of a particular protein or food?
