• New laptop, Windows 8.1, attempting dual install. Ubuntu installer doesn't 'see' existing OS

  - by Flaminica

  Though I've used Ubuntu for a few years, I'm new to installation. Previously I had help and now I'm doing it alone (moved across the world). Windows 8.1 came preinstalled on my new laptop (Toshiba Satellite C70-A-17C - Core i5, 8 GB RAM, 750 GB HDD). I have already followed a few steps I found online to prepare for a dual install (with Ubuntu 14.04). I backed up Windows, created a bootable Ubuntu USB and DVD (just in case one didn't work), turned off fast boot and secure boot, and shrunk C:/. The new unallocated drive portion is 292.97 GB. After shrinking C:/, I restarted Windows a couple of times to make sure everything was working fine (it is). I then attempted to install with the Ubuntu live USB. However, the Ubuntu installer doesn't see that Windows 8.1 is already installed. I don't understand, and don't want to mess with Ubuntu partitioning when I don't know where the partitions will be created. My concern is that, if I go further with the installation process, Windows might be overwritten or compromised in some way. I then tried to reboot using the Ubuntu live DVD, thinking I might get a different result. However, I can't figure out how to make the laptop boot from the CD drive. I went into the BIOS and found no option there, either. Any help is very appreciated! EDIT: Looks like I can't link directly to each photo. Here is my album of screenshots: http://imgur.com/a/zChCo Here you can see that there's no option to boot from CD drive, only USB. Everything looks okay so far. I don't understand this. Ubuntu has not yet been installed. Unmounting partitions? (I chose 'no'.) Even though the laptop came pre-installed with Windows 8.1, the Ubuntu USB installer can't see it. I chose 'something else'. I need to pick and format partitions. I scrolled down and took a second shot to include all information. Completely lost and cancelled installation.

• Serverless Web Application

  - by Andrea Di Persio

  In my company we work on a software that produce reports in html format. My bosses love the fact that static html pages can be moved across computer simply by moving/copying a folder and no web server is involved, so the customer only need a browser. The problem is that they asking me to implement a lot of feature which is very hard to implement properly and in a clean way without an application server. Frames cross domain problem, the impossibility to work with GET and POST data, no URLs routing...is very hard to work with this limitations. Anyone had similiar experience and wants to share their tricks/suggestion ? Do I need to tell my boss 'there is no future without a web server'? Regards.

  I installed Ubuntu 12.04 LTS using Wubi in the D: drive of my PC. I have Vista installed in the C: drive. I have forgotten my password for my Ubuntu Admin Account.

• Added 2nd HDD, created new mount point for /mnt/datanew, get you are not the owner

  - by user212383

  I am completely new to Linux and have been asked to extend a VM running Ubuntu, I thought I would test this first so have just installed it in a test VM, I added the 2nd hard drive and used Gparted to format it with ext4 so I now have a drive called /dev/sdb1 I then created a new directory called mnt/datanew I then mounted that using the below command sudo mount -t ext4 /dev/sdb1 /mnt/datanew I thought I was doing well until when I went into home folder / file system mnt / datanew I noticed I couldn't create a new folder etc, I check the properties and it said I don't have permission as its all root How do I change this, I need to create some data and then test extending the partition as I want to see if it has any impact.

• Attempting to install Ubuntu 11.10 along side Windows 7 Professional 64bit. Installer doesn't recognize an operating system present

  - by KichigaiDave

  System Details: Asus Sabertooth 990FX motherboard AMD FX-8120 CPU 16 GB DDR3 1600 Corsair Vengance RAM (4x4) EVGA Nvidia GTX-560Ti video card 2x Dvd/cd rw dirves 1 Bluray RW drive 1 Orico USB 3.0 & eSata panel 1 Sabrent floppy bay card reader w/USB 2.0 port 760W pc power & cooling PS OCZ agility 120GB SSD (Windows 7 Professional 64bit installed in an approx 80gb partition, NTFS. There is also a "System Reserved" partition shown in disk management at 100mb in size, also NTFS) That leaves about 32GB usable free, un-partitioned space in which I hoped to install Ubuntu. However when I run the Ubuntu 11.10 AMD64 installer, it doesn't show there is even an operating system installed. It just shows the entire drive as free-unpartitioned space. Just not sure what to do here. I was thinking about using the Wubi installer, but i don't know about that. Is the performance reduction pretty drastic? Thanks,

• Need Help with partitions and such Dual Booting 13.10 w/ windows 7

  - by Aymax

  so I've spent the past couple days freaking out about this and looking for answers, and I decided to resort to asking on forums. probably should have before I wasted 2 entire days. so I am trying to DUAL-INSTALL Ubuntu 13.10 with my x64 Windows 7 home premium computer. I have 6 gb of ram, 1TB hard drive, and a 3.3GHZ dual core processer (just in case it matters). I've managed to figure some things out. I've burned the ubuntu files onto a DVD, and I have been able to successfully run it off the disk. I also shrunk my Windows partition by 120Gb and partitioned that for Ubuntu (all using the windows Disk Manager). Problems: When I turn my computer on with the DVD in the tray, the computer cant find windows. it flashes a screen real quick that says something about not being able to find an operating system, and then goes to "grub" and asks what i want to do with Ubuntu. this scares me, because I don't know if that means that I will not be able to boot windows if I install Ubuntu. The Ubuntu 13.10 installer does not detect my Windows operating system. I only have the options to Erase everything on my drive, or "something else." I choose that, which brings me to 3 I don't understand the partition table. I have no idea which drive im selecting to install stuff on, much less which one to select. I tried to tell by the amount of memory partitioned off, but none of the numbers seem to be accurate. Plus, all the names are dev/sda(#). I know Ubuntu knows the name of my partition, because on the sidebars it shows the names of the different drives, including the partition I made; so why don't they use the names? I have no idea what I'm going to be erasing. I've read that I should know which is which by the file system type, but they are all NTFS, including the one I made. my only other option was FAT, none for EXT2 or any of that like people said to do. My main concerns are that of accidentally erasing windows or not being able to access windows. any feasible solution is helpful, weather it helps me with the install or to make Ubuntu see windows. I realize this question has been asked much, but i have found no feasible answers so far. I am relatively new to this, and have never installed an operating system before, so I do not know most of the jargon. please keep it relatively simple, please. I am not a programmer. Thanks.

• Misused mke2fs and cannot boot into system

  - by surlogics

  I installed Ubuntu with WUBI in Windows 7 64bit, and I had installed Mandriva 2011 with a disk.

• What's a good way to get an IT internship? [closed]

  - by user1419715

  I'm a second year CS student who's worked really hard to build and expand my skills. I've spent the past week now trying to find a place to volunteer (i.e. work for FREE) so I can get a little bit of in-the-door experience with web development. I have a portfolio with several decent projects, a handful of languages and other hard/soft skills that employers constantly say they're clamoring for. I can't even get people to take my calls. This is me offering to work for them for FREE, remember. I'm in a reputable program at a respected school, get decent grades and...yeah, I've worked really hard to be presentable. On the rare occassions I actually get to speak to somebody at a design firm they hedge and do everything they can to get me off the phone. Nobody's ever expressed even the slightest interest in taking me on. The answer to the experience problem is supposed to be "you need to spend a year or two building up a big portfolio of projects on your own" so that employers will be impressed. I've done that. Websites, standalone apps, etc.. Nobody will even look at my resume, though. Question: Why does there seem to be so little interest in taking on upaid interns in the world of IT? Update: Sorry you all think I'm too aggressive or angry. It wasn't my intent to be a jerk to people while asking them for their opinions. That said, how would you feel if employer after employer turned you down cold when you offered yourself to them without asking for remuneration? One can't even get an unpaid job in this economy now, it seems. How am I going about my search? I find web firms in my area and contact them via email with a brief sales pitch of myself and a resume attached. Then a couple of days later I follow up with a phone contact. Nobody--anywhere--is advertising for interns of any kind. If there were I'm sure there'd be about 500 resumes per position, even unpaid. I've had good experiences in the past with cold-calling firms for actual paid jobs in other industries (hiring is a pain in the ass process and a call like this can show initiative while reducing a busy employer's need to do all the hiring overhead work), so I thought volunteering would work at least as well. My skills are pretty good for a CS student and include the usual suspects: HTML/CSS/Javascript, Python, Java, C, C#/.Net etc etc. I made a point on my resume to tie each ability claim to a project as well. Oh, and regarding the "working for free still costs the employer money" argument: that's an excellent point I hadn't though of. But it means...what? I have to pay the employer for the privilege of working there now?

• Can I properly use NS2 on latest Ubuntu 12.04?

  - by Nwe Nwe

  I am a novice user for Ubuntu because I need to work with NS2. NS2 properly work only in Linux, Ubuntu. Now, I wonder if it can properly work on latest version Ubuntu. My current window is Window7. I also want to use Window7. So, which one will be better on parallel booting of Window 7 and Ubuntu or using VMWare on Window7 to install Ubuntu. My RAM is 4G. My processor speed is 1.6G. If I use VMWare, my C drive is only extra 10G. So, does VMWare can work properly in D drive? Please let me know which way is the best for my situation. I hope the advice from anyone. Thanks in advance.

• attempted WUBI install corrupted Vista

  - by oliver zimmermann

  Tried to install WUBI through Google Chrome on my Vista machine. Got through the usual warning about running new software, selected "continue" and waited for a prompt about where to install WUBI. Never got one...waited about 30 minutes (computer still running fine)...decided to reboot and try again. OOOOOPS. Was not able to reboot Vista. Ouch. When I run a Vista recovery CD it tells me there is an "X:" drive on what used to be my C: drive and it cannot find a Vista install to recover. Anyone seen this ? It is making me very happy... THANKS!!!!!!!!!!!!

• Ubuntu 12.04 x64 doesn't boot anymore after a power failure

  - by Felix

  I'm a Windows user and I have no experience with Linux and Ubuntu. I installed Ubuntu 12.04 on my netbook (Asus 1215B) and everything works fine. Yesterday I ran the "update application" and updated over 120 "things" (I have no idea what exactly). After that I was asked to reboot, and I did. Ubuntu starts again and at the load screen with these 5 dots that normally begin to change color, it freezes. After 20 minutes I took out the battery to try another reboot (yes, not the the best idea), and now nothing happens. I boot from the HDD and I get an Error BOOTMGR is missing. I have important data on the hard drive. Is there an option to get this fixed? Or if not, to at least get the data from the hard drive?

• Ubutnu 12.04 mdadm inactive

  - by user32274

  For a while now, my RAID 5 has ceased to work. Everytime I tried "madm --detail /dev/md127", its states all the drive and drive info, but that two of the drives have been removed. After some restarts, doing the same thing, i am getting /dev/md127 does not appear to be active. When I go into DiskUtil, I can see all 6 Hard Drives healthy and present, and i can see the Raid 5 at the bottom under Multi-disk Devices. However, the Raid says 0.0kb, and is not active. Please help and let me know how to proceed from here. I would really like to avoid rebuilding the RAID, especially because all 6 drives seem to be healthy and present. Thanks so much.

• In setting up dual Boot with Windows XP and Ubuntu, which OS do I install first?

  - by markl

  I'd like to install both Ubuntu 12.04 and Windows XP on a Dell laptop, and I was thinking about using a dual boot structure, and using the bulk of my hard drive as empty hard drive space to share files between the two operating systems (so choice of file system type is very important in this set-up). The kind of partitioning structure I would like to use is Partition 1 - Ubuntu 12.04 (root) (20GB) Partition 2 - Ubuntu /home (20GB) Partition 3 : Free Space (560GB) Partition 4 : Windows XP (35GB) Partition 5 : SWAP (3GB) (Total Hardrive Capacity is ~640GB) My question is; what is the best way to go about setting up this kind this system? Should I install Windows XP first and setup the partitions, and then install Ubuntu which I believe will install the GRUB bootloader for OS booting choice or Do I install Ubuntu first, setting up the available partitions and then perform a WIndows install? Please let me know if there is anything in this setup that I have left out and should know about, including things related to setting particular partitions as logical or primary, and whether the boot partition and the filesystem partition should actually be two separate partitions.

• Ubuntu One lost most of my files!

  - by Max

  I keep in my UbuntuOne the source code of my projects as a back up. In the past it worked and I never had problem. It happened that I had to change the hard disk of my laptop and I installed a fresh Ubuntu 12.10 in the new one. First time I connected with UbuntuOne it downloaded my files, but when I went to see my projects almost all my c++ source code files were missing!!!... I tried to check if I still have them on UbuntuOne by accessing from the web but nothing... my work is lost forever. I don't know who to ask for help? Is there a way to get back my precious files? Honestly I can't trust this service any more, I'm very disappointed. (edit: thanks God I found a back up in one of my external hard disks. I won't trust Ubuntu One any more, it's buggy and quite slow. )

• Best places for offshore development?

  - by Smokefoot

  In the past I've worked a lot with Philippines and India as a Offshore Development Unit in our Projects. My experience is mixed. Some are very good, some not. But I am thinking about other countries for offshore development. Personally I would like to have here some developers onshore, but the situation here is very hard and good developers are very hard to find. So we have to develop offshore. So my question is very simple. Do you have any experience with offshore and where would be a good place for development? By the way I am at the moment very interested in Russia and Ukraine. I know some Russians and Ukrainians and I like their engagement and the way they work. Maybe these countries are good for offshore development too?

• If you need more than 3 levels of indentation, you're screwed?

  - by jokoon

  Per the Linux kernel coding style document: The answer to that is that if you need more than 3 levels of indentation, you're screwed anyway, and should fix your program. What can I deduce from this quote? On top of the fact that too long methods are hard to maintain, are they hard or impossible to optimize for the compiler? I don't really understand if this quote encourages better coding practice or is really a mathematical / algorithmic sort of truth. I also read in some C++ optimizing guide that "dividing up a program into more functions improves its design" is frequently taught in CS courses, but it should be not done too much, since it can turn into a lot of JMP calls (even if the compiler can inline some methods by itself).

• Delete all traces of windows from Ubuntu

  - by TheOm3ga

  I used to have a dual boot in one of my hard disk drives - Ubuntu and Windows 7. Then, I added a SSD which is now my main hard disk drive, and I'm using it for Windows 7 completely, keeping Ubuntu in the old HD. I restored the Grub so everything works ok, except for one thing. Everytime I update the grub, it detects two windows: Found Windows 7 (loader) on /dev/sda1 Found Windows 7 (loader) on /dev/sdb1 Obviously, I don't want it to detect the Windows on sdb1. Because I no longer use it (I manually deleted the files). What can I do about that without wiping out completely the partition?

• Ubuntu Doesn't Start from USB After Installation

  - by Fred Venus

  My computer refuses to boot from the USB even after I change everything that I can possibly think of on my motherboard's BIOS. But I have booted from the USB twice in the past. The first time is when I first got the computer and needed to install a new operating system. The second time is when I installed Windows onto the whole hard drive and needed to reinstall Ubuntu. It seems that it only refuses to boot if there is already an existing installation of Ubuntu on the hard drive. Any ideas on what is going on?
