After I update the ubuntu version from 14.04 to 16.04 system not booting. screen sowing   grub&gt;   Then I tried to update the grub as follows, 1/ boot the system using USB boot. 2. open the terminal and type   sudo update-grub   it throws the below error message.  /usr/sbin/grub-probe:error:failed to get canonical path of '/cow'.   Googled and tried many forum answers. But could not solved.  Greatly appreciated your help.
I am trying to install Ubuntu 12.10 for quite some time, and passing hurdles one by one. Now I am in a situation as follows.  I have got a PC and 10 GB HDD which will be totally dedicated to Ubuntu so no option of Wubi and dual boot.  I was trying to install from DVD, but it is getting stuck at "Out of frequency" error. So I had to adapt for USB boot option. But my PC is USB non bootable, so workaround is "Plop Boot Manager". So I am doing the installation procedure as follows:   starting  from a CD drive which is having plop installed. opting for for USB boot in plop options. booting begins from USB. monitor eventually gives "out of frequency" error press Shift+Alt+F1 to get the terminal. open the grub with sudo nano /etc/default/grub. do necessary changes. sudo update-grub.   Now here I am getting error as follows:   /usr/sbin/grub-probe:error:failed to get canonical path of /cow.     My system is   P4 3.06 GHz, 1 GB ram , 10 GB HDD without an OS, monitor CRT lg StudioWorks (7 years old). Mobo Mercury P4 266a NDMx (865 equivalent). The whole system is perfectly in working condition under XP, but it is USB non bootable, and all other devices working perfectly.  What should I do next?

I bought a new tablet, but Android (2.3.1) shows that it has only 150MB free of 256MB, and it should have 512MB.  I checked the file /proc/meminfo, MemTotal information. It only shows 256MB. Is there a possibility that the Android "hid" 256MB of RAM from the user? Last Logon Time of All Users - RDP server not on a domain Why do my shortcut icons get broken on Windows 7? I have a strange problem. My icons seem to disappear randomly on my Windows 7. They were there a while back, now they ain't.  It happens often and quite randomly. Anyone know a fix? In mathematics, we like talking about idempotent matrices. In a masters program that I am currently enrolled in, I have heard one professor pronounce it one way, and another professor pronounce it another way. The  explains it better than I could:  Is there a correct pronunciation for idempotent? Is it like omnipotent (om-nip-o-tent), so id-EMP-o-tent, or is it more like the two seperate words idem + potent I'd say EYE-dm-POT-nt, but then I speak Brit. Charles Matthews 07:57, 30 Jun 2004 (UTC) Ditto, but then I speak Australian ;) Dysprosia 08:01, 30 Jun 2004 (UTC) Actually the British is more like EYE-dm-PO-tnt, I guess. Charles Matthews I'd just like to pedantically point out that it would be pronounced i-DEM-po-tent because because syllable onsets are maximized. daesotho 20:33, 21 Oct 2004 (UTC) The American pronunciation puts primary stress on the second syllable ('dem') and secondary stress on the fourth syllable ('tence'). Could somebody more familiar with IPA than I am please add this to the article as an accepted pronunciation? My American dictionary says |ˈīdemˌpōtənt| for the adjective. I speak American (non-natively) and I wouldn't stress the second syllable for itempotence. My only question is, right now it says /ˌaɪdɪmˈpoʊtəns/ -- but can't it be stressed on the first syllable too? Should we add /'aɪdɪmˌpoʊtəns/ as an alternative? -- 87.160.141.177 (talk) 14:50, 3 June 2011 (UTC) And by the way I think it's silly giving a pronounciation guide as this is just imposing a particular accent. (For what it's worth I pronounce idempotent with a short 'i', as in the word 'id'). Alex Selby I agree with Alex Selby - the pronunciation guide should be extended to show the variation, or removed. Strictly, there's no reason for the first i to be long (neuter idem has a short first syllable in Latin), and I can't find any authoritative source which advocates the pronunciation given.

Determining members of local groups via C# I wondered whether anybody knows how to obtain membership of local groups on a remote server programmatically via C#. Would this require administrator permissions? And if so is there any way to confirm the currently logged in user's membership (or not) of these groups? "User accounts" or "users account" How can I have colored and underlined links with hyperref? I would like the internal hyperlinks generated by  to be colored and underlined.    Reading some of the package documentation, I know that these \hypersetup keys exist:   colorlinks: when true, color the link; when false, draw a border around the link and color that. linkcolor: the color of the link (requires colorlinks=true to have any effect) linkbordercolor: the color of the link border color (requires colorlinks=false to have any effect) pdfborderstyle: keys for the pdf borderstyle dictionary.  I don't know what keys and values exist for this dictionary, but I do know that pdfborderstyle={/S/U} or pdfborderstyle={/S/U/W 1} can change the link border from a box to an underline.   But it seems impossible with this key structure to have colored links (requiring colorlinks=true and colored borders (requiring colorlinks=false.)  Here is a minimal (non)-working example ():  \documentclass{article} \usepackage{xcolor} \usepackage{hyperref}  \hypersetup{colorlinks=false,linkbordercolor=red,linkcolor=green,pdfborderstyle={/S/U/W 1}}  \begin{document} \section{To See}\label{tosee} \vskip2cm \hyperref[tosee]{just to see} \end{document}   With colorlinks=false (the default), the text is black and the border is red.  With colorlinks=true the text is green and there is no border. Bending of light - photon's inertia instead of mass Open Windows Terminal as admin with WIN+R Heroes of Might and Magic VI seems to have installed a program called "Uplay", which it uses to launch (in addition to Steam, mind!)  What exactly is Uplay supposed to be? I notice that when I stop playing, it captchalogs the highlights of my past session (achievements earned, etc.) - which is kinda cool, but also kinda creepy and big-brotherish. Given that I value my privacy, is there anyway to play Uplay games without using Uplay?  Is this just Ubisoft's infamous "always-on" DRM? What is the most convenient way to read definitions of in-memory symbols when we don't have the source files? (Spelunking tools) Get display resolution from the command line for Linux Desktop I'm looking for a method of reporting display resolution.

Using a transistor as a switch I am attaching a motor to an ATmega32 chip. I want to build an H-bridge but before doing that, I want to control the motor using the chip. I bought few NPN Transistors from RadioShack. I have 5V running though the breadboard. I attached Vcc to the Collector, Base to the Pin, and Emitter to the motor. And other wire of motor is hooked up to Ground. Unfortunately, the power coming out of the transistor is too low, the motor is barely moving (As opposed to when I hook up my motor straight to 5V). What is wrong? Do I need a different transistor or is my setup wrong? If it is the transistor, can you please recommend the right one, I am not too good at those. Does the series $\sum \sin^{(n)}(1)$ converge, where $\sin^{(n)}$ denotes the $n$-fold composition of $\sin$? I'd like to use a background image for my world, but I'm not sure how to do it.   Right now I am using the sun as a lightpoint and it looks like sky and a flat plane (not realistic). I was thinking of just using a mountain background image for the world.  I've done that through textures etc. but I don't see ANYTHING in render even though it shows in worlds?  What am I doing wrong?    Also what's a cheap quick fix for cases like mine so it looks like the world isn't JUST blue sky?  Thanks guys! How do I catalog files on several external hard drives that I want to store off-line? I have quite a few external hard drives that I want to store off-line, and possibly off-site.  The contents is not saved in a structured manner, however; basically  there's lots of project data for lots of projects.  Is there any software for Windows XP that will catalog all the hard drives, so I can search the catalog, find the files, and get the ID of the disk that has the content? Get the last item in an array Proof that a sequence of continuous functions $(f_n)$ cannot converge pointwise to $1_\mathbb{Q}$ on $[0,1]$ Calculate the limit including binomial coefficients $\lim\limits_{n\to\infty}{\sum\limits_{k=n}^{5n}{k-1 \choose n-1}(\frac{1}{5})^{n}(\frac{4}{5})^{k-n}}$  It's clear that we can simplify the limit a little bit, after which we get:  $\lim\limits_{n\to\infty}{(\frac{1}{4})^{n}\sum\limits_{k=n}^{5n}{k-1 \choose n-1}(\frac{4}{5})^{k}}$  I could further simplify the expression, but I feel like there's a more elegant solution.   Give me a hint, please
