  • How to install Ubuntu Server 12.04 in a Virtualbox VM with UEFI boot enabled

    - by Deleted
    I have a server which I'd like to install Ubuntu 12.04 on, but I've had some problems and thought it would be nice to get things working in a Virtualbox VM with the same features as the server. I want to enable UEFI-boot in the VM. I "Enable EFI" in the System / Motherboard settings for the VM. I make sure the Ubuntu Server 12.04 ISO is inserted when I boot. And yet I get stuck in the UEFI boot console when I start the VM. How do I install Ubuntu Server 12.04 in a UEFI boot-enabled Virtualbox machine?

  • Steps to install solely ubuntu 13.04 on Dell inspiron 14z ultrabook with SSD+HDD

    - by rishy
    I have tried a few things like disabling the Intel smart response, choosing AHCI in BIOS. But there are certain problems I am still facing. I can't see my SSD during the installation of ubuntu (I am planning to install Ubuntu on my SSD and other files on HDD). When I run Ubuntu my laptop gets overheated and battery backup reduces to 90 minutes. (I guess it's related to my graphic driver ATI Raedon HD 7570). Cooling fan seems to run at its fullest, it was working much better in windows. So, overall I wanted to know what are the exact steps I need to follow to install Ubuntu on my SSD and then use my HDD to keep other files, How can I get rid of overheating and battery backup problem?

    - by mathew
    Hello, I had a system running Win 7 Home premium and ubuntu 10.04, side by side dual boot.I got an ubuntu 10.10 image disk so I decided to update.But during the installation I think I made a mistake by specifying the whole partition, and after installation of ubuntu 10.10 I saw that my windows and all the other data was gone.there was around 250GB of it.Is there any way I can recover this data??I had a lot of irreplacable photos and collections on the drive.I do have a recovery cd for my windows, but it does not detect any windows os.thanku very much.

  • Bringing the xenbr0 interface up on XEN under Ubuntu 8.04

    - by iyl
    I installed XEN on Ubuntu 8.04 using this tutorial: http://www.howtoforge.com/ubuntu-8.04-server-install-xen-from-ubuntu-repositories but after I reboot with the XEN kernel, I don't have xenbr0 device. I see that network-bridge script runs and it creates peth0 device, but not xenbr0. I have a very basic IP setup, with a single static IP defined in /etc/network/interfaces. The only unusual thing is that my hosting (1&1) gave me a netmask 255.255.255.255, so I had to add the default gateway with this script: /sbin/route add -host 10.255.255.1 dev eth0 /sbin/route add default gw 10.255.255.1 Everything else is plain vanilla Ubuntu 8.04.

  • Can I run Ubuntu directly under Windows 8?

    - by huahsin68
    Text below is extract from the article, Windows 8 Tip: Virtualize with Hyper-V. Better still, Windows Virtual PC offered a feature called XP Mode, free for users of Windows 7 Professional, Enterprise, and Ultimate, which included a full working copy of Windows XP with Service Pack 3. But the big deal here is that as you installed applications in the virtual copy of XP, they would be made available through Windows 7’s Start Menu. And you could run these applications, side-by-side, with Windows 7 applications on the Windows 7 desktop. It was a seamless, integrated experience, ideal for those one-off application compatibility issues. I was thinking to install VirtualBox in Windows 8 and then run Ubuntu as guess OS. Since Hyper-V is a Type-0 hipervisor, may I know does this bring the same benefit if I have Ubuntu Linux install as a virtual guess OS? Meaning, if I turning the Ubuntu on (the guess OS), does the Ubuntu still able to access the hardware information like nVidia display card or processor information? I'm just curious to know can this be done?

  • My PC suddenly reboots

    - by ChocoDeveloper
    Yesterday I opened my PC hub (after like, 5 years) to add more RAM and a new HDD. It was full of dust and balls of fluff, so I cleaned it a bit by blowing. I also removed the fan that was attached to the motherboard (I think it's there to cool the processor) and I cleaned it also by blowing and with a paintbrush, then put it back where it was (it had 4 weird plastic screws, it wasn't easy). Then I added 2 x 2Gib of RAM (Kingston 1333MHz), and the new HDD (Western Digital Caviar Blue 1TB SATA 3). I couldn't find another wire like the one my first disk had, which was thicker, but there was one that was more flat, so I plugged it and it worked fine (I also plugged the wire that I think is for the data, which looks like many little wires glued together). I'm running Ubuntu 12.04, and in the new disk I've just installed Windows 7. Between yesterday and today, two reboots ocurred while working on Ubuntu. I haven't used Windows 7 that much so I don't know if it will happen there too. So where can I begin to debug this?

  • VirtualBox running Ubuntu 11.10 in Win7 is suddenly way too slow

    - by elithin
    For two months I've been running Ubuntu 11.10 64bits in VirtualBox 4.1.12r77245 but today everything has been really slow, freezing all the time. I've had to restart the VM about 7 times already because Ubuntu just freezed in the middle of a task. I'm using my laptop, it's a LG P420 i5 with 4gb ram. I don't know if it could be an update of Ubuntu or VB, but I really need it to work. Any guesses? Thanks in advance

  • Linux Has Become Very Slow Dealing With Large Data

    - by Kohjah Breese
    Last year I bought a computer, for around $1,800, so it is relatively high-end. When I first got it I was particularly pleased at how quick it dealt with large MySQL queries, imports and exports. But somewhere along the way something has gone wrong and I am not sure how to diagnose the problem. Any job that involves processing large amounts of data, e.g. gzipping file c. 1GB+, UPDATEs on large MySQL tables etc. have become very slow. I just performed an intensive alter statement on a 240,000,000 row table on a remote server, which is lower spec. This took about 10 minutes. However, performing the same query on a 167,000,000 row table on my computer went fine until it hit 860MB. Now it is only writing about 1MB every 15 seconds. Does anyone have any advice as to debugging what the issue is? I am using LinuxMint (based on Ubuntu 12.04.) The home partition is encrypted, which really slows down gzip. I have noticed the swap is barely used, but am not sure if that is because there is more than enough RAM. The filesystem is ext4. The MySQL server is on a separate hard drive, but it was fine when I first installed it. Other than the above issues, there are no other problems with it. I am going to install a fresh Ubuntu on the 4th hard drive to see if that is any different.

  • How to install TortoiseHG on Ubuntu

    - by Webnet
    I just downloaded and installed the latest Ubuntu and it doesn't look like I'm used to. I don't see any Mercurial developer tools in the Ubuntu Software Center. I got on http://tortoisehg.bitbucket.org/download/index.html and it looks like it can be done, but I'm not entirely sure how. I've done some Googling but the results I keep running into are on older versions of Ubuntu. Any ideas on how I can make this happen?

  • An increase to 3 Gig of RAM slows down Ubuntu 10.04 LTS

    - by williepabon
    I have Ubuntu 10.04 running from an external hard drive (installed on an enclosure) connected via USB port. Like a month or so ago, I increased RAM on my pc from 2 Gigs to 3 Gigs. This resulted on extremely long boot times and slow application loads. While I was understanding the nature of my problem, I posted various threads on this forum ( Questions # 188417, 188801), where I was advised to gather speed tests, and other info on my machine. I was also suggested that I might have problems with the RAM installed. Initially, I did not consider that possibility because: 1) I did a memory test with a diagnostic program from DELL (My pc is from Dell) 2) My pc works fine with Windows XP (the default OS), no problems with memory 3) My pc works fine when booting with Ubuntu 10.10 memory stick, no speed problems 4) My pc works fine when booting with Ubuntu 11.10 memory stick, no speed problems Anyway, I performed the memory tests suggested. But before doing it, and to check out any possibility of hardware issues on the hard drive, I did the following: (1) purchased a new hard drive enclosure and moved my hard drive to it, (2) purchased a new USB cable and used it to connect my hard drive/enclosure setup to a different USB port on my pc. Then, I performed speed tests with 1 Gig, 2 Gigs and 3 Gigs of RAM with my Ubuntu 10.04 OS. Ubuntu 10.04 worked well when booted with 1 Gig or 2 Gigs of RAM. When I increased to 3 Gigs, it slowed down to a crawl. I can't understand the relationship between an increase of 1 Gig and the effect it has in Ubuntu 10.04. This doesn't happen with Ubuntu 10.10 and 11.10. Unfortunately for me, Ubuntu 10.04 is my principal work operating system. So, I need a solution for this. Hardware and system information: DELL Precision 670 2 internal SATA Hard drives Audigy 2 ZS audio system Factory OS: Windows XP Professional SP3 NVidia 8400 GTS video card More info: williepabon@WP-WrkStation:~$ uname -a Linux WP-WrkStation 2.6.32-38-generic #83-Ubuntu SMP Wed Jan 4 11:13:04 UTC 2012 i686 GNU/Linux williepabon@WP-WrkStation:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 10.04.4 LTS Release: 10.04 Codename: lucid Speed test with the 3 Gigs of RAM installed: williepabon@WP-WrkStation:~$ sudo hdparm -tT /dev/sdc [sudo] password for williepabon: /dev/sdc: Timing cached reads: 84 MB in 2.00 seconds = 41.96 MB/sec Timing buffered disk reads: 4 MB in 3.81 seconds = 1.05 MB/sec This is a very slow transfer rate from a hard drive. I will really appreciate a solution or a work around for this problem. I know that that there are users that have Ubuntu 10.04 with 3 Gigs or more of RAM and they don't have this problem. Same question asked on Launchpad for reference.

  • how to reinstall/repair ubuntu 12.04 after dual boot installation fails with windows 7

    - by Rini
    I have installed Ubuntu 12.04 on my preinstalled windows 7 Sony vaio s series laptop following instructions here: http://www.linuxbsdos.com/2012/05/17/how-to-dual-boot-ubuntu-12-04-and-windows-7/ Everything went well and I am able to boot in to windows after complete installation of Ubuntu. Now following instructions on web I tried to add Ubuntu to my BIOS using Easy BCD (but forget to add windows 7 entry). As a result, I loose windows 7 OS and can't boot in to either OS then I successfully repaired windows 7 using recovery CD. Now my problem is that I can't reinstall Ubuntu 12.04 using Live CD it halts every time before disk partition step giving error. "ubi-partman crashed". "ubi-partman failed with exit code 141. further information may be found in /var/log/syslog. Do you want to try running this step again before continuing? If you do not, your installation may fail entirely or may be broken." and, any choice to continue will result in the same error. I looked in to /var/log/syslog but not able to understand what is error. Then, I ran sudo fdisk -l to view my partitions and it shows me only one partition. Probably, all the partitions I created for Ubuntu 12.04 are lost while running windows 7 recovery CD. So, I don't know whether the Ubuntu is still there or probably corrupted. My boot-info URL is: http://paste.ubuntu.com/1202146/ Please tell me how to remove this error so that I can reinstall/repair Ubuntu 12.04 Thanks in advance. R Shukla My boot-info URL is: http://paste.ubuntu.com/1202146/ Please tell me how to remove this error so that I can reinstall/repair Ubuntu 12.04 Thanks for your help! I tried to boot from the CD but I every time it give me error before disk partitioning step. Also, I am unable to start Gparted. "ubi-partman crashed". "ubi-partman failed with exit code 141. further information may be found in /var/log/syslog. Do you want to try running this step again before continuing?

  • ubuntu 12.10 installation failure

    - by Eidelmaim
    Here i am asking this question again because someone deemed it a duplicate to another topic which i over looked and NOTHING AT ALL in that topic pertained to my problem. If your going to close a topic believing it is a duplicate at least do somke reasearch into WHY you think its a duplicate and provide a like to a better source. How do i get past this installation username and password issue? I downloaded ubuntu 12.10 directly from Ubuntu.com and created a bootable USB with linuxlive. after loading the boot drive and ubuntu begins, it goes directly from the purple ubuntu startup screen directly to a black DOS like prompt asking for a ubuntu login. this is COMPLETLY before any installation -begins. i need some help with this. FYI : this is what it is saying after it goes to the login area in the DOS (Full black screen) like screen. Ubuntu 12.10 ubuntu tty1 ubuntu login: now i will provide a few images of the problem i am having. and because i DONT HAVE ANY OS on the computer BECAUSE ubuntu WONT go PAST this... i have to snap these pictuires with a cell phone and upload on another PC. these links are in chronological order from time of pressing power button to time i am presented with log in screen : image 1 image 2 can only post 2 links in messages... will post additional links in comments So, again... how do i get past this ? this is entireley before ubuntu is installed on my system. my PC specs... Homebuilt computer: Motherboard is a Asus Sabertooth x58 with a intel core i7 processor. Mushkin memory @ 12gbs. 4ea. Seagate 150gb hard drives. nvidia GTX 260 graphics card. i initially attempted to install to raid 5. failed. i broke down the raid and attempted to install to a single drive with all other drives disconnected from the PC. again, thanks in advanced for any assistance.

  • Ubuntu Install 11.10 doesn't recognize Windows 7 installation with new HDD

    - by arlendo
    Replaced my crashed HDD with a Seagate 2TB Sata (bought from a company who pulled it from a working computer, OS unknown) and did a fresh install of Windows 7. Windows shows 100MB boot partition (bootable NTFS) and 200GB Windows partition (NTFS), the rest is unallocated. Win7 Disk Management says the partitioning type is Master Boot Record. Win7 boots and runs fine. Ubuntu 11.10 Install procedes to Allocate Drive Space screen and should say This computer currently has Windows 7 on it. What would you like to do? Instead, it says something like Install doesn't detect any existing OS on this computer. When I click on Something else, the partition table shows only the unallocated space of 1.8TB. Ubuntu Disk Utility says Partitioning: Master Boot Record, but GParted Live says Partition Table: gpt. It was my original intention to have the Windows boot partition and application partition, then install Ubuntu 11.10 using boot, root, swap, and home partitions, and maybe another partition just for data (mostly photos). Currently, I would be happy if I could just get Ubuntu installed along with Win7. I am aware of the MBR limits of 3 Primary partitions and 1 Extended partition. I suspect that my new HDD is partitioned for GPT and that is why Ubuntu can't see the Win7 installation. Am I on the right track? I was going to use Windows Disk Management to convert GPT to MBR but I only have the one drive on my AMD-64 mini-computer and it says I have to empty the drive of all partitions before I can access the Convert command. And I can't find any bootable software that would allow me to do that conversion. Here is the result of sudo fdisk -l: ubuntu@ubuntu:~$ sudo fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sda: 2000.4 GB, 2000398934016 bytes 224 heads, 19 sectors/track, 918004 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xd4a68c18 Device Boot Start End Blocks Id System /dev/sda1 * 2048 206847 102400 7 HPFS/NTFS/exFAT /dev/sda2 206848 419637247 209715200 7 HPFS/NTFS/exFAT ubuntu@ubuntu:~$ Keep in mind that I'm a definite newbie to screwing around with the inner workings of Ubuntu. I previously had Ubuntu 10.04 running with Vista and I don't remember even having to partition anything that wasn't automatic in the install. Thanks for taking a look here. My Win7 is running fine but I miss my Ubuntu.
