Hello Ubuntu Community,  Ok so basically, I had a dual boot and yesterday I deleted the linux partition not thinking about what could happen. All was fine till today because I restarted my pc. As I started my pc I got into the grub rescue menu. I was a bit confused as of why it still exists so I searched online. I found some videos but those weren't really helpful because I would need a Windows USB/CD or a Linux live USB/CD. So right now I am pretty much stuck without any ideas on how to continue with this problem. I am a starter at linux and all that, I honestly just wanted to try it out because of the AMD Drivers  Thanks for helping!
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.
Why does the review system disable the "First Posts" and "Late Answers" if I reached daily upvote limit? I was reviewing on , and I faced a weird thing. I can review "Close Votes", "Low Quality Posts", and "Suggested Edits" if I reached my daily vote limit, but I can't for "First Posts" and "Late Answers". Why?    If they just deserve an upvote/downvote then they should not include in the review system. But if we can improve them through leaving comments and by editing the posts then why can't we access them? Indecomposable limit ordinals What is the maximum or minimum tire width I can fit on my bicycle We often get questions on bicycles.stackexchange about fitting wider or narrower tires to bicycles. We have a large number of these with answers suiting the specific bike or style of bicycle in question, but I have been unable to find one that provides a generic answer covering off all things that need to be considered. For most bicycles, the answer is the same regardless of the specific style and sizes of tires in question.   This is intended as a canonical question that we can point closed questions to.

What would be the the mathematical equivalent of this excel formula? =PMT() I need to create a JavaScript form that does the same calculation as this =PMT() function.   mortgage = 220000 rate= 4.75% term = 30   The example formula I have is =PMT(4.75%/12,30*12,220000*-1)  What would be the equation for this function? I tried to look up this function but it doesn't explain it very well. iPhone App CrashReport Can we modify "Ask question" to automatically suggests tags based on your question content.   So instead that user needs to type "team-foundation-server" or "TFS" or "TeamFoundationServer" he will see list of tags auto-populated with ajax which he (or she) can then select and it will be associated with the question. So basically only thing we need is code which will cross-match question content with list of known tags while user is typing and display results in some nice ajax-enabled list/cloud/whatever UI control. This should be separate control for tags suggestions so user still has option to use standard tag list input to type-in tags.  In this case, instead of three (or more) tag variations we would have only one tag for Team-Foundation-Server. What is a good data plan for Internet surfing in northern Italy? I've checked the webpages of some their providers, but franly, just like in the case of those in my own language, I literally cannot find my way around them. So if you wouldn't mind sharing a word of two or advice.  I'm looking for a good solution for mobile internet surfing in northern Italy, that can be connected to a laptop (you know, that usb stick with a SIM card inside kind of thing). 15 Gb or so at some decent speed. Can you perhaps give a recommendation or two of what to get?    Edit: Just to define what I'm looking for exactly. A data plan of 15 Gb with an internet key (usb stick into which a SMS card goes) that you plug into a laptop. Preferably non-contractual, so I can cancel when I leave. I am not interested in surfing on my mobile phone since due to size I still prefer the smaller Nokia-like models for calls (smaller to carry) - no internet on them. When voting to migrate an off-topic question, why is the list of sites limited? On per-site metas, users are given a rank based on meta participation, and this ranking is seen on the default tab of the users page on each per-site meta. How is this participation numerically calculated to give a ranking? Is it by votes? Something else? Are community wiki posts included in this?

How to compute $$\sqrt{(1\sqrt{(2\sqrt{(3\dots)})})}$$ &amp; $$\sqrt{(1+\sqrt{(2+\sqrt{(3+\cdots)})})}$$?  I understand that  $$\sqrt{(1\sqrt{(2\sqrt{(3\dots)})})}=(1^{1/2})(2^{1/4})(3^{1/8})\cdots$$  and  $$\sqrt{(1+\sqrt{(2+\sqrt{(3+\cdots)})})}=(1+(2+(3+(\cdots))^{1/8})^{1/4})^{1/2} $$  How to Proceed further? If two ends were a certain "length" apart were they therefore at rest (or at least rigid) to each other? I have a small issue with configuring the lidR  for parametrizing the extracted raster files with grid_metrics() function.  My question is how to set in the catalog options that:   be able to overwrite the results with a second run if I want to run my script several times and I do not want to name each output differently. instead of .tif I would like to get .grd files as output.   My current code (which is working) is the following:  normalizedctg = catalog(workingdirectory) opt_output_files(normalizedctg) &lt;- paste(workingdirectory,"/clipped/normalized/{XLEFT}_{YBOTTOM}_height",sep="") height = grid_metrics(normalizedctg, max(Z),res = resolution)   But with a second run on the same code I get the following error:  Error in .getGDALtransient(x, filename = filename, options = options,  :    filename exists; use overwrite=TRUE How do i install drush for a drupal site which is on shared hosting? Why is "letter" not plural in "two letter words"? How to install Broadcom wireless drivers offline? I have installed Ubuntu alongside Windows 8.1. But the wifi is not working in Ubuntu (perhaps the drivers are not present), which worked fine in windows. Also I cant connect with Ethernet since my laptop does not have an Ethernet port. So is there any way for me to connect to the internet in ubuntu?
