I downloaded Ubuntu 20.04 ISO file and used UNetbootin to boot Ubuntu in my hardrive. But when I restart my laptop and boot into UNetbootin it gives me an error that a windows file is missing, but when I boot into Windows 8.1 and it is fine. Please help. In short, I used UNetbootin to boot Ubuntu into my hardrive but gives me an error. It will be really helpful if you can help me.
This is the third time I've tried to install Ubuntu Server 14.04.03 64-bit on the same laptop, and each time it caused different problems.  Each time I wrote the same iso image to a USB flash drive by using a different application and OS.   Universal USB Installer (pendrivelinux.com) from Windows WinImage writer from Windows built-in image writer from Linux Mint 17.2    The iso image is the same in all three cases, the USB flash drive is the same, and the laptop is the same. However each time the installation of Ubuntu gave me different installation options. For example, the last time I installed Ubuntu, it didn't show all the packages to choose while installing (Basic Ubuntu server, etc.).
Should we close 'fix my program' questions Recently, I've seen many questions with this structure:   a wall of code a request for the community to debug it by inspection   You can find a nice selection .  I offer, as a thesis, that these questions are not consistent with the stated goals of SO. They do not, usually, create a resource of use to other people.   As a community, we could politely but firmly tell these askers to do enough of their own work to come up with a concrete, specific, programming question, other than 'can someone tell me what's wrong with this?'  Don't get me wrong. I'm sympathetic to people with problems. I have not been downvoting or voting to close these, because the community seems to be inclined in general to be helpful. I'm asking, are we really doing the right thing by encouraging the site to populate with these?  If the consensus is 'yes' then I'll just slink back to my cave. I'm not interested in starting a campaign here. Is there a way to separate variables between multiple notebooks? Submission on hold on arxiv I have recently submitted a paper to arXiv, but the arXiv moderators put my paper in status "on hold", because they have to make a decision on the right classification for the paper.   To those who have experienced a similar situation, how long did it take before they made a decision and published the paper on the arXiv? I just want to have an idea of how long I will have to wait. A guide to moderating comments Q&A blank in Stack Exchange Android app v1.0.95 - S10e/Android 10 Recently upgraded to a Samsung S10e and Android 10, but all Q&amp;A in the Stack Exchange app v1.0.95 are blank.  The title and comments are visible, but question/answer posts are just white space. Accessing the About page in the app is also blank.  I tried clearing data, cache and re-installing the app, but I still get the same behaviour. What can I do if a repository/PPA does not have a Release file? Differences between "however", "although","albeit", etc Graph of Reputation Over Time for all linked accounts how many instances for a class exists at runtime in java How to simulate data that satisfy specific constraints such as having specific mean and standard deviation? Further anonymize deleted accounts by changing the username in close/delete notices When an account is deleted, the username in the user's posts and comments is changed to a generic user&lt;userID&gt;. But the username stays the same on close and delete notifications on posts the user had voted to close / delete1. I think it shouldn't, especially for users who used their real name as their username, if they chose to distance themselves from the site and remove their accounts, it makes sense that they wouldn't really want their name plastered on close and delete notifications.   A perhaps easy way to avoid the actual username remaining visible would be to change it to the generic user&lt;userID&gt; (or anything generic enough, like "anonymous") prior to deletion, and wait a bit for the generic username to propagate all over the site. If I'm not horribly misreading , this was part of the process in the old days.   This could be automated or added as a suggestion to the .  Glaring example can be seen , where the deleted user also posted a comment where their name is properly anonymized:        1 I've seen it on close notifications and self deleted answers. I'm not sure it happens on deleted questions, or deleted answers that aren't self deletions, and I don't have a way to verify it - other than stumbling on them accidentally What experiment would disprove string theory? Why does light in a room not form constructive and destructive interference patterns? Can I find the connected components of a graph using matrix operations on the graph's adjacency matrix? If I have an adjacency matrix for a graph, can I do a series of matrix operations on the adjacency matrix to find the connected components of the graph? Math mode macro in TeXstudio I want to set up a macro in TeXstudio for math mode which displays $*$ and places the cursor at position *. So far I have tried using $%|$ but upon triggering, this macro does not allow text insertion at the placeholder.  EDIT: The method above works fine if the macro shortcut is set to the default Shift+F1. However, changing the shortcut to another combination, as I would like to do, seems to be the cause of the problem. If I short sell stocks of a company but do not close my position by buying them back, what will happen? I realize it is a bad thing, but what exactly? I will need to pay a penalty? Hero who is against enhancements but has some himself What to look for in the datasheet when choosing a MOSFET? update-java-alternatives vs update-alternatives --config java On Ubuntu 12.04 LTS I have installed Sun's JDK7, Eclipse, and the Arduino IDE. I want the Arduino to use OpenJDK 6 and want Eclipse to use Sun's JDK 7.   From my understanding I need to manually choose which Java to use before running each application. This led me to the update-java-alternatives -l command. When I run this I only see the following:   java-1.6.0-openjdk-amd64 1061 /usr/lib/jvm/java-1.6.0-openjdk-amd64   but when I run update-alternatives --config java I see the following:   *0  /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   auto mode 1  /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java   manual mode 2  /usr/lib/jvm/jdk1.7.0/bin/java                   manual mode 3  /usr/lib/jvm/jre1.7.0/bin/java                   manual mode   I don't understand why the update-java-alternatives doesn't display the same 3 options. I also don't understand how to switch between OpenJDK6 and JDK7. How I can go about using the OpenJDK6 for Arduino development and Sun JDK7 for Eclipse/Android development? How can I install Skype on 32-bit Ubuntu 14.04?
