Question: Is it possible to find, locate, or install the windows 10 boot manager through the grub 2 command line? If so, what are those commands? I cannot boot into windows of course and i can not enter ubuntu either. If the questions above are not possible, what are my options? I only want/need windows. Situation: I have a dual boot (windows 10 &amp; Ubuntu) installation on my laptop HDD, and no longer wanted to keep ubuntu on my hdd. I wanted to erase all trace of ubuntu so that i could safely transfer data to an ssd. So Naturally, as someone new to linux, i thought it made sense to simply delete the linux partition from Windows’ Disk Manager since windows was (pre)installed first. Then migrate the data over to the clean ssd. Problem: After deleting the linux partition and extending the c drive to take over unallocated space, I can no longer boot windows. As soon as i turn on my laptop, the GNU GRUB ver 2.04 shows up. In the command line it displays: “grub&gt; ” (It is Not grub rescue) Typing “exit” simply brings me back to the same screen. The UEFI menu that i have doesnt have any option change the boot back to windows bootmgr. I dont have a windows installation disk, or any external windows backup device that was recommended. And I dont currently have but could make another ubuntu live usb, if necessary. But it would be cool if i could do this in grub Neither the hdd nor the ssd can boot windows nor ubuntu. But both devices bring up the GRUB&gt; command line. I now know that data migration moves everything except the boot manager itself. Ive also learned that installing ubuntu gave the booting reigns to ubuntu and took that control away from windows. Which is why uninstalling ubuntu from windows caused this issue.. So my question is, since ubuntu is gone, is windows boot manager also erased? Or is it possible to locate it through GRUB?
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.
curlicue letters with mathptmx package How to show letters like  with mathptmx package?  I'm using pdfLaTeX with mathptmx package becasue its gooding looking normal math font letters a-z, A-Z. However, if only with this package, \mathsrc{...} is reported as "undefiend sequence" and \mathcal{...} is curlicue style like the following:  \mathcal{F} shows . If I add \usepackage{mathrsfs}, \mathcal{F} and \mathscr{F} are the same as .  What I expect is \mathcal{F} shows  and \mathscr{F} show the one in previous line.   What should I adjust? I hope mathptmx package is still being used.  Minimal code script goes like that:  % using PdfLaTeX \documentclass[journal]{IEEEtran} \usepackage{amssymb,amsmath,amsfonts} \usepackage{mathptmx}  \usepackage{mathrsfs} \begin{document} $$\mathcal{F}$$ $$\mathscr{F}$$ they are the same \end{document} Prove Equivalence Relation in G Hei, guys!  I'm having some trouble with the next problem:  Let $A$ and $B$ be subgroups of $G$. Show that $\sim$ is an equivalence relation when it is defined as follows: $g\sim g'\Leftrightarrow g' = agb$ for some $a$ from $A$, $b$ from $B$.  Should I prove this is valid for any a and b? It says for some elements a and b. But I might as well take the unit element.   Could you give me a clue on how to solve it?  Cheers! I need to end my visa waiver period when leaving States to Canada so that I don't exceed the period of 90 days. But form I-94 is no longer a physical card, it's only online.  How do I know or ensure that it will be terminated and will not continue counting the days once I leave to Canada? Is their a way to move multiple vertices gradually at a time? I have moved multiple vertices gradually but a set of vertices at a time not all at a time, as shown in the animation below (First I moved the four vertices from top, then three, then two and at last the last vertex).  I wanted to do the same thing as shown in the animation below but all at a time. How to count the number of occurrences of each item in an array?

Animated movie that had black robots that turned people into stone late 1960s to 1970s It was a weird sci-fi animated movie I saw only a little bit of it. This is what I recall:   It was old but had color, so I assume it was late 1960s to early 1970s. The animation and style reminded me of  but it wasn't as psychedelic. The setting was an alien planet with all sorts of bizarre creatures. The tech was advanced but not a dominant aspect of the planet's culture. The people lived simple and peaceful. The protagonist is a man with bluish skin like the others. The antagonists were humanoid shaped black robots that shot a beam that would turn people into stone. I am working on a print for my wall and I am trying to create something like this:      I have already created the letters in Illustrator and now I am adding the colors in Illustrator and then exporting everything to Photoshop and then using the liquify tool to blend the colors to create a similar effect. I also used the healing patch tool to blend in the hard edges.  Is that the right way of doing it? Or is there another way? Expansion of $(1+\sqrt{2})^n$ Update Manager asking me to update kernel but apt-get upgrade does not? Until I went to army, I (had been / used to be / was ) a introverted person. - which one is right? Until I went into the army, I (had been / used to be / was ) an introverted person. And after I I finished army service, I became more confident.   I think all of these are possible.  As for had been, I'm referring to the state of me being introverted before the accident that happened in the past. So, I think I can use had been.  And at the same time I feel I can use used to be and was.. If I don't want to emphasize the time gap between two accident, I feel I don't need to use past perfect. So I think this problem depends on how I'm going to say something.   which one is preferable? and what is the difference? How to cross-reference an inequality with \cref?

It's ray shielded, so only torpedoes will do.  To do this, the Rebel pilots had to fly down a very long trench, where they were vulnerable to fire from any TIE fighters to the rear.  In fact they were so vulnerable that most of the pilots on this run were blown up once the Imperial forces started responding to the attack. This battle is in space, so the fighters can, if necessary, come to a dead stop and hold their position while firing.  Also, when Luke fired his torpedoes, they took a 90 degree turn and went straight into the port.  So the torpedoes didn't have to be fired from in the trench. We also didn't see any gun emplacements firing at the fighters from near the exhaust port, but if there were, the Rebels could have targeted them and taken them out or run interference to make it hard for the towers to fire at a fighter targeting the exhaust port.  (They were already dodging fire in the trench as well.) A fighter could have easily flown directly at the exhaust port, firing torpedoes multiple times on approach and, if not under fire (or if protected by other fighters), could have actually stopped and taken time to target the exhaust port before firing. Is there any valid in-universe reason that the pilots had to fly down the trench before firing on the port?  And if there is, is there any reason they had to enter the trench so early? Just for reference, here is the  on YouTube.  There's no explanation given for having to fly in the trench. Does a List guarantee that items will be returned in the order they were added? Does a List&lt;T&gt; always guarantee that items will be returned in the order they were added when enumerated?  Updated: Thanks for all the answers folks, puts my mind at ease. I had a quick poke around the List&lt;T&gt; class with .NET Reflector (should've probably done that in the first place) and indeed the underlying store is an array of T (T[]). jQuery .delay does not delay Are dark energy and zero-point energy the same thing?

Angle between 2 points Given the following image:   $\hskip{1.5 in}$   Supposing $A(100, 300)$ and $B(300, 100)$, how can I find the angle $\alpha$ between A and B?  On a side note, what's the main difference between a point and a vector? translating a point to a vector is as simple as Point = Vector? Sometimes I find articles where the terms are interchangable
