I deleted the partition containing Ubuntu from my computer -- manage -- disk management  and now my laptop is showing:  error: no such partition. grub rescue&gt; 3   Please tell me how can I open my regular Windows 7 now.
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.
This one seems to be a common question in most forums and all over the web, it is asked here in many formats that typically sound like this:  In SQL Server -  What are some reasons the transaction log grows so large? Why is my log file so big? What are some ways to prevent this problem from occurring? What do I do when I get myself on track with the underlying cause and want to put my transaction log file to a healthy size? Xerces error: org.apache.xerces.impl.dv.dtd.DTDDVFactoryImpl Bind a key for multiple units to use the same spell How can I encrypt and decrypt a string in C#? jQuery doesn't work after content is loaded via AJAX I'm looking for an algorithm which when given a latitude and longitude pair and a vector translation in meters in Cartesian coordinates (x,y) would give me a new coordinate. Sort of like a reverse Haversine. I could also work with a distance and a heading transformation, but this would probably be slower and not as accurate. Ideally, the algorithm should be fast as I'm working on an embedded system. Accuracy is not critical, within 10 meters would be good. If a Matrix Has Only Zero as an Eigen-Value Then It Is Nilpotent Prove that a matrix with only zero eigenvalues must be nilpotent.   How will I be able to prove this? I want to do a survey of textbooks in set theory. Amazon returns 3582 books for the keywords "set theory". A small somewhat random selection with number of references in Google scholar is the following.   Two questions:    What textbooks in set-theory are considered standard?  What is a good place to aggregate standard references (of textbooks)?    (I'm only interested in text-books, which as a format already provide a kind of standardization)  Textbooks on set theory (author: title (year) #Google Scholar citations )   Thomas J.

Please leave any feedback or questions about this FAQ on .     Two weeks ago, we  to directly address concerns over pronoun usage. We tried to anticipate likely questions, but&hellip; missed the mark by quite a lot. Based on Gareth McCaughan’s excellent post, “”, we’ve gone back to the drawing board and written a new FAQ that aims to address actual questions that have been frequently asked in these discussions.  If you read only one thing, the answer to question #1 under The Basics sums up our goals in publishing this guidance:     It would be rude to refer to a man as "she" or a woman as "he". Some people are neither male nor female and might, for instance, ask to be referred to as "they". When someone indicates what pronouns should be used to refer to them, please use the pronouns they state as you would others.   This is a learning process for most of us - from authors to readers to moderators to employees of Stack Exchange, Inc.  Let’s all try to approach this with good intentions and a willingness to learn from one another.  Big thanks to Gareth for leading by example here, and to everyone who has stepped up to ask and answer the important questions!  What's all this stuff about pronouns in The Code of Conduct?  The  has two direct references to pronouns:   “Use stated pronouns (when known).” “Prefer gender-neutral language when uncertain.”   What does all of this mean and how can I as a user understand and follow the CoC guidance? How do I start a process from C#? I've read before that, by the Principle of Explosion, if a theory is inconsistent, then absolutely any statement can be proven within it.  Obviously, there are statements which are independent of ZFC (Continuum Hypothesis, etc). It seems to me that this proves that ZFC is incomplete. Why does it not then follow that ZFC is consistent? It seems to me that we could say "Assume ZFC is inconsistent. Then the the Continuum Hypothesis is provable in ZFC. But the Continuum Hypothesis is neither provable nor disprovable in ZFC. Therefore ZFC is consistent."  What am I missing here? Based on , I figured that there might be multiple questions for distinct locales. Why do the most common transactions to or from bank accounts in the US require waiting one or more days before they are completed? In the information age, it seems like we should be able to transfer money instantly (or nearly so). I'm trying to identify fantasy book series I encountered some time ago. Here are things I remember:   it was a fantasy setting but with some s-f elements; with many worlds and possibility to travel between them; resembling  setting a little, the two main races were non-human and probably hostile to each other,  a labyrinth (?), which somehow played an important role in the plot, a protagonist was some kind of emissary and was sent on a mission to another worlds  time period: 80s - 90s    Does anyone know what it is the name of the series? How to Detect workstation/System Screen Lock/unlock in windows OS using java? Do multiple instances of the Extra Attack feature stack? The WotC article  creates the &quot;Favored Soul&quot; sorcerous origin, which grants the the sorcerer the Extra Attack feature at level 6. Say I made Favored Soul sorcerer go up to level 6, and then multiclassed into Ranger to get its Extra Attack at level 5. Would the two Extra Attack features stack so that I could get 3 or 4 attacks in a turn? iOS crash log catch, debug info.. Catch and send via email to the Dev team Is there any (even the most subtle) difference between the meaning (or connotation) of that is and i.e.?  I used to be convinced that they were synonyms, until an editor of a scientific journal changed all occurrences of i.e. into that is. Is there a single word or very short phrase to describe the act of contemptuously referring to someone by using a diminutive "nickname", with which that person is not normally associated?  For example, referring to Henry Wadsworth Longfellow as Hank Longfellow? Or William Penn as Billy Penn? Rotation Path Not Shown in Graph Editor I created a couple of LocRot keyframes but the rotation path and keyframes aren't shown in the graph editor (no, they aren't hidden).
