  • How do I get my Mac to boot from an Ubuntu USB key?

    - by user11621
    If you select "USB" and "Mac" on this download page, it gives a series of command line instructions to make a USB key which the MacBook will boot into Ubuntu from. I've followed them to the letter two or three times on different USB keys, and it doesn't work. There's a very great deal of technical discussion about EFI etc. but this set of instructions seems to suggest it should just work, but it doesn't. Help? I'm increasingly unhappy with the more locked-down approach Apple is taking, and I'd quite like to start using Linux with a view to transitioning over to using it as my main operating system, but booting from the CD takes forever, runs slowly and I'm really hoping to get it moving off USB. Can anybody help me?

  • Install Ubuntu Netbook Edition with Wubi Installer

    - by Matthew Guay
    Ubuntu is one of the most popular versions of Linux, and their Netbook Remix edition is especially attractive for netbook owners.  Here we’ll look at how you can easily try out Ubuntu on your netbook without a CD/DVD drive. Netbooks, along with the growing number of thin, full powered laptops, lack a CD/DVD drive.  Installing software isn’t much of a problem since most programs, whether free or for-pay, are available for download.  Operating systems, however, are usually installed from a disk.  You can easily install Windows 7 from a flash drive with our tutorial, but installing Ubuntu from a USB flash drive is more complicated.  However, using Wubi, a Windows installer for Ubuntu, you can easily install it directly on your netbook and even uninstall it with only a few clicks. Getting Started Download and run the Wubi installer for Ubuntu (link below).  In the installer, select the drive you where you wish to install Ubuntu, the size of the installation (this is the amount dedicated to Ubuntu; under 20Gb should be fine), language, username, and desired password.  Also, from the Desktop environment menu, select Ubuntu Netbook to install the netbook edition.  Click Install when your settings are correct. Wubi will automatically download the selected version of Ubuntu and install it on your computer. Windows Firewall may ask if you want to unblock Wubi; select your network and click Allow access. The download will take around an hour on broadband, depending on your internet connection speed.  Once the download is completed, it will automatically install to your computer.  If you’d prefer to have everything downloaded before you start the install, download the ISO of Ubuntu Netbook edition (link below) and save it in the same folder as Wubi. Then, when you run Wubi, select the netbook edition as before and click Install.  Wubi will verify that your download is valid, and will then proceed to install from the downloaded ISO.  This install will only take about 10 minutes. Once the install is finished you will be asked to reboot your computer.  Save anything else you’re working on, and then reboot to finish setting up Ubuntu on your netbook. When your computer reboots, select Ubuntu at the boot screen.  Wubi leaves the default OS as Windows 7, so if you don’t select anything it will boot into Windows 7 after a few seconds. Ubuntu will automatically finish the install when you boot into it the first time.  This took about 12 minutes in our test. When the setup is finished, your netbook will reboot one more time.  Remember again to select Ubuntu at the boot screen.  You’ll then see a second boot screen; press your Enter key to select the default.   Ubuntu only took less than a minute to boot in our test.  When you see the login screen, select your name and enter your password you setup in Wubi.  Now you’re ready to start exploring Ubuntu Netbook Remix. Using Ubuntu Netbook Remix Ubuntu Netbook Remix offers a simple, full-screen interface to take the best advantage of netbooks’ small screens.  Pre-installed applications are displayed in the application launcher, and are organized by category.  Click once to open an application. The first screen on the application launcher shows your favorite programs.  If you’d like to add another application to the favorites pane, click the plus sign beside its icon. Your files from Windows are still accessible from Ubuntu Netbook Remix.  From the home screen, select Files & Folders on the left menu, and then click the icon that says something like 100GB Filesystem under the Volumes section. Now you’ll be able to see all of your files from Windows.  Your user files such as documents, music, and pictures should be located in Documents and Settings in a folder with your user name. You can also easily install a variety of free applications via the Software Installer. Connecting to the internet is also easy, as Ubuntu Netbook Remix automatically recognized the WiFi adaptor on our test netbook, a Samsung N150.  To connect to a wireless network, click the wireless icon on the top right of the screen and select the network’s name from the list. And, if you’d like to customize your screen, right-click on the application launcher and select Change desktop background. Choose a background picture you’d like. Now you’ll see it through your application launcher.  Nice! Most applications are opened full-screen.  You can close them by clicking the x on the right of the program’s name. You can also switch to other applications from their icons on the top left.  Open the home screen by clicking the Ubuntu logo in the far left. Changing Boot Options By default, Wubi will leave Windows as the default operating system, and will give you 10 seconds at boot to choose to boot into Ubuntu.  To change this, boot into Windows and enter Advanced system settings in your start menu search. In this dialog, click Settings under Startup and Recovery. From this dialog, you can select the default operating system and the time to display list of operating systems.  You can enter a lower number to make the boot screen appear for less time. And if you’d rather make Ubuntu the default operating system, select it from the drop-down list.   Uninstalling Ubuntu Netbook Remix If you decide you don’t want to keep Ubuntu Netbook Remix on your computer, you can uninstall it just like you uninstall any normal application.  Boot your computer into Windows, open Control Panel, click Uninstall a Program, and enter ubuntu in the search box.  Select it, and click Uninstall. Click Uninstall at the prompt.  Ubuntu uninstalls very quickly, and removes the entry from the bootloader as well, so your computer is just like it was before you installed it.   Conclusion Ubuntu Netbook Remix offers an attractive Linux interface for netbooks.  We enjoyed trying it out, and found it much more user-friendly than most Linux distros.  And with the Wubi installer, you can install it risk-free and try it out on your netbook.  Or, if you’d like to try out another alternate netbook operating system, check out our article on Jolicloud, another new OS for netbooks.

  • Ubuntu boot hangs after message "Running /scripts/init-bottom ... done"

    - by Douglas B. Staple
    I've been trying to copy a Proxmox container based on the Ubuntu Precise Standard template to a VirtualBox VM. I am now stuck at a point where my new Ubuntu/VirtualBox VM hangs after the message "Running /scripts/init-bottom ... done" during boot. I started by installing Ubuntu Server 12.04.4 LTS on a VirtualBox VM. Ubuntu Server 12.04.4 LTS was the closest "official" Ubuntu ISO to the Proxmox container OS I could find. I installed all updates on both the Proxmox container and on the VirtualBox VM. The idea was to get same version kernal running on the ProxMox container and VirtualBox VM. sudo apt-get update ; sudo apt-get upgrade ; sudo apt-get dist-upgrade sudo reboot rsync the entire proxmox container to a temporary directory in the VirtualBox VM: cd / mkdir /tmp/backup rsync -e ssh -av --exclude={/dev,/proc,/sys,/tmp,/run,/mnt,/media,/lost+found,/boot,/selinux} root@my_proxmox_container_hostname:/ /tmp/backup Shut down the virtual machine, and boot the VM with a bootable linux image. I used the Desktop image of Ubuntu 12.04 LTS, ubuntu-12.04.4-desktop-i386.iso Drop to a root prompt. Mount the VM root filesystem: sudo mount /dev/sda1 /mnt Remove files from most of /mnt cd /mnt sudo rm -rf bin etc home lib opt sbin root usr var Move all of the files from /mnt/backup into /mnt sudo mv /mnt/tmp/backup/* /mnt Rebooted system. For me, at this point the system freezes after starting, after the message: Running /scripts/init-bottom ... done I've tried reinstalling GRUB and all manner of other thing. I am almost ready to give up.

  • How can I display additional boot and shutdown information on the Windows 7 welcome screen?

    - by Daniel Saner
    There is a small tweak, I believe it is a registry key, that allows to display additional information on the Welcome and Shutting down screens of Windows 7 (and most likely Vista, too). I have activated this tweak on one of my systems; unfortunately I forgot how I did it, and I can't seem to find the website that originally gave me that information. Usually, the Windows 7 welcome screen will just display "Welcome" when logging in. With the tweak activated, my Welcome screen gives status information such as "Loading user settings" or "Preparing desktop". When shutting down, the default screen simply says "Shutting down". With the tweak activated, it gives additional status information such as "Stopping Windows services". This appears the same way that Windows gives information when updates are installed or configured during the startup or shutdown procedure, and I find them quite helpful in getting a feel for what task takes how long during that process. The only setting I was able to find is the Boot log checkbox on the Boot tab of the msconfig application. However, this results in Windows displaying console logs of drivers it is loading, etc., instead of the animated Windows title. This is NOT the setting I am looking for. The "additional boot information" setting that I have activated on this system still displays the regular animated Windows logo, and only replaces the strings displayed on the blue Welcome and Shutdown screens. Could someone direct me to the registry key (or whatever setting) that is used to get this behaviour? Edit: Here are a few pictures of the enhanced Welcome and Shutdown screens taken with my mobile phone—they're in German though. Login screens "Waiting for User Profile Service" and "Preparing desktop": Logout screen "Stopping Windows services":

  • WOL doesn't work if set to anything other than `a` but this setting makes it boot all the time

    - by Elton Carvalho
    I manage a small "cluster" of 4 Xeon machines with Intel boards in my lab. They are all plugged to a 5-port 3-Com switch with static IP addresses like 10.0.0.x. They are all running OpenSuse 11.4 and their /home/ is served by one of the machines (node00) via NFS. They are plugged to an UPS that can keep them on for ca. 15 minutes, but there are lots of electric shortages due to "unscheduled maintenace" that are longer than this. So they end up being powered down without notice. If I set the BIOS to turn them on after power shortages, the issue is that they all boot at the same time and, if node00 decides to run fsck in the /home/ partition, it does not finish booting before the others try to NFS mount their /home/. I am trying to make wake on lan work, so I can choose to boot the NFS clients only after the server has successfully booted. The problem is that when I run ethtool I get an output like this: Supports Wake-on: pumbag Wake-on: g Theoretically, it is set to wake on MagicPacket(tm), according to the manual. But sending the WOL packet using wol -i 10.0.0.255 $MACADDR does not wake up the box after I shut it down with halt. The ethernet link led blinks after I send the packet, so it appears to be getting to the machine. However, if I set it up with ethtool -s eth1 wol bag, the machine always wakes up right after halting, even if I don't send the Magic packet. This means that the device can wake up with LAN activity, but seems to be ignoring the magic packet. Setting wol ag does not wake the box with the MagicPacket. Does setting wol a mean that it should boot with any broadcast message? How can I diagnose the issue of the machine not waking up with the MagicPacket even though I am sending it and it's set up to wake up with it? Thanks in advance!

  • No boot device found. Press any key to continue

    - by Andrew Banks
    I took out the hard drive from my Dell Latitude E5420 notebook, put in an ADATA S599 solid state drive, and installed Ubuntu 11.10. When I boot, the Dell BIOS splash screen appears with a progress bar, which quickly fills up, and the screen goes black. All of this is like it was before. At this point, the OS splash screen should fade in. Instead, I was dismayed to see simply the following, in white text on a black screen: No boot device found. Press any key to continue After looking around for the Any key (just kidding) I press a key, and the Dell BIOS splash screen appears again with a progress bar, which quickly fills up, and the screen goes black. This time, however, the Ubuntu splash screen shows up, Ubuntu opens up, and all is normal. Every time I shut down, however, this happens again. It's like a game the computer and I play together. The computer has never started up without first saying: No boot device found. Press any key to continue and it has always started up after I press any key to continue. It also starts up fine if I click Restart instead of Shut Down. Thoughts?

  • Can a OS be copied from one hard drive to another and still boot?

    - by AlexMorley-Finch
    Background My computer gets stuck on the make and model screen after the BIOS screen, aka the Toshiba screen. After some research I've realized that the problem is the hard drive. I'm using an old 250gb model that USED to be used for backup purposes, however I loaded windows 7 ultimate onto it This hard drive has trouble getting up to full RPM therefore cannot boot correctly until its warmed up. meaning that my pc needs to be restarted several times before it boots (once it took my 13 reboots to get my pc on!) From my research its either that, or lack of power supply, and I've tried multiple PSUs. Question I have my OS and all my files on this 250gb HDD... If I were to literally open the explorer, and copy EVERYTHING (including hidden files obviously) from this 250gb, to a spare 500gb I've got knocking about... Will it boot if I just copy everything? I cannot be bothered to load another OS onto my PC so if there is a way I can just copy the existing one over from one HDD to another and have it boot normally. This would be epic! I've heard about HDD cloning software. But before I purchase and/or download this software, I need to know if i can just copy the OS over through the windows explorer

  • How do I ensure my Apple keyboard connects on boot?

    - by Stacey Richards
    I am using Ubuntu 10.04 on a laptop and have an Apple wireless keyboard which pairs fine. Every time I turn my computer off and back on again my keyboard stops working. I have to use the keyboard on my laptop to log in. Once I've logged in, in order to get the wireless keyboard to work, I need disconnect and reconnect it by: Clicking on the Bluetooth icon, select Apple Wireless Keyboard from the drop down menu, then click on Disconnect. Clicking on the Bluetooth icon, select Apple Wireless Keyboard from the drop down menu, then click on Connect. Looking through syslog, to see what's happening during boot, I find: Nov 25 10:29:21 sony kernel: [ 24.525372] apple 0005:05AC:0239.0002: parse failed Nov 25 10:29:21 sony kernel: [ 24.525379] apple: probe of 0005:05AC:0239.0002 failed with error -14 and then later in syslog, once I've disconnected then connected the keyboard, I find: Nov 25 10:30:14 sony bluetoothd[1247]: link_key_request (sba=00:21:4F:49:8A:DB, dba=E8:06:88:5A:E0:D4) Nov 25 10:30:14 sony kernel: [ 79.427277] input: Apple Wireless Keyboard as /devices/pci0000:00/0000:00:1d.2/usb8/8-1/8-1:1.0/bluetooth/hci0/hci0:12/input11 Nov 25 10:30:14 sony kernel: [ 79.427611] apple 0005:05AC:0239.0003: input,hidraw1: BLUETOOTH HID v0.50 Keyboard [Apple Wireless Keyboard] on 00:21:4F:49:8A:DB I can't find anything helpful when Googling "apple: probe of failed with error -14".

  • Grub can not boot after resizing windows XP (NTFS) partition. What is to be done? [closed]

    - by cipricus
    Possible Duplicate: How to Repair Grub while dual booting ( win7 / ubuntu 11.10) I had installed Lubuntu on a PC with Windows XP and used dual boot for some time with no problems. Since I had almost abandoned Windows (kept it for printing...) I decided to resize its ntfs partition and add the free space to my Ubuntu space. Tried that with a gparted stick and a live cd but would not work due to an issue related to the ntfs partition: gparted signaled with a red exclamation point that there was a problem with that partition. I read that a checkdisk might solve it but in the end used EaseUS in Windows to shrink (resize) the ntfs partition and create a new one (ext3) from the space left. All seemed ok with that procedure: but resizing the partition and moving the data might have affected the grub file: or whatever the following message means, which I get when trying to start my pc: error: file not found grub rescue> Booting from a live cd I see, beside the shrinked windows partition and my old linux one, the newly created partition, containing a directory called lost+found that I cannot open. Can I fix the grub file and recover both my XP and Lubuntu installations?

  • Oneric Aspire One. After latest 11.10 update to Linux 3.0.0-9 boot hangs at staement "Starting Bluetooth"

    - by hevh
    I have today updated the version of Linux on Ubuntu on my Acer Aspire One. The boot hangs on the statement "Starting Bluetooth". Help please!! EDIT1: I get the grub menu when I start the netbook and it doesn´t matter which version of linux I choose the resulkt is the same. It gets as far as the Ubuntu spash screen then drops into command line mode then hangs on the line "Starting Bluetooth". I can log in and have tried various forms of the apt-get command to fix the system but with no result. I do not need bluetooth at the moment and so could remove the application if I knew how. (have tried apt-get remove bluez). When I use the command sudo apt-get -f install I get an error message saying "There's not enough space in /var/lib/mysql/" folowed by several other error messages. I have spent some time looking for similar problems and solutions using google but so far got to nothing to help. Thanks EDIT2: I have since discovered when running Knoppix or slitaz from a usb stick that the file managers report the hard disc as having no space. However GPARTED reports it as having 3.69gb. I do recall making space on the hard drive by deleting some old files and emptying trash whilst the update was running; perhaps its related. Any suggestions for how I can recover the apparently lost space from hard disc without losing the data. I have backups of the actual data but do not wnat to lose the applcations configuration. Thanks Kev

  • Why is my dual-boot Ubuntu partition showing up as a peripheral "root.disk"?

    - by Don
    I recently installed Ubuntu 12.04, which I had been booting from a usb key, as a dual-boot on my machine running Windows 7. From what I had read online while researching, I was prepared to have to shrink the Windows partition and all that. But I never had to - it really was just a few clicks here and there and it was installed. I'm still pretty confused about it, but whatever, it worked, and the two peacefully coexist on my machine, and I have broken things to fix before I worry about fixing unbroken things. So yesterday I got it in my head to look at my partitions (I was considering making an all new partition to install the Windows 8 Release Preview). What I saw confused me. Here's a screenshot of the disk utility. At this moment, there is nothing connected to my computer, and nothing in any of the optical drives/ports/card readers/etc. Can you help me figure out what's going on here? Don's Machine is, I believe, my Windows partition - that's the name I assigned my machine from Windows Explorer. PQSERVICE is from what I can find online also Windows, but having to do with backup. And SYSTEM REQUIRED, if I browse it in Ubuntu, is definitely something to do with booting, and I believe it is also Windows'. According to the sizes shown, those three together should use up my 500 GB HD. Then further down, as a "peripheral device", it lists that 31 GB disk. This is obviously my Ubuntu (Model:Linux Loop:root.disk), but why is it showing up as a peripheral? So, to sum up those questions and to add some more random ones I had: Why is Ubuntu showing up as a peripheral device? If the Windows sections take up all 500 GB, where does Ubuntu live? If I renamed the disk partitions, would my life become a nightmare (seriously - can I safely rename them)? Why didn't I have to resize the Windows partition in the first place? Would giving Ubuntu more space improve its performance (it hangs alot)? Is it possible to have a partition for each OS (Windows 7 & 8, Ubuntu), a partition for files, and a separate partition for backups? Is this towards the good or bad idea end of the spectrum? @Elfy, would that explain why it keeps hanging? I guess I'll backup my files, rip it out, and reinstall it correctly later on today.

  • Install problem on UEFI, Windows 8 new desktop

    - by albuquerque mat
    I just bought an HP desktop, p6-2326s, which has windows 8 installed. I have tried booting a Ubuntu live disc but the machine won't boot it. When I bring up the UEFI boot menu it offers a selection of UEFI BOOT SOURCES, windows boot manager, dvd drive, IP4 Ethernet controller, or IP6 Ethernet controller. If I select the dvd drive with the CD in it I get the message "Secure boot violation, Invalid structure detected. Check secure boot policy in setup." With all other selections it just boots into windows. So where do I go from here?

  • What does the BIOS setting XHCI Pre-Boot Mode do?

    - by Jamie Kitson
    I have a BIOS setting called XHCI Pre-Boot Mode. If I have this enabled USB devices which aren't plugged in at boot are never recognised, if I set it to Disabled then USB devices work normally. The brief BIOS description says "Enable this option if you need USB3.0 support in DOS." Which I don't, but it also says "Please note that XHCI controller will be disabled if you set this item as Disabled." So does that mean that USB3 is disabled with this option?

  • Can ISC dhcpd operate as a proxy dhcp server for PXE boot?

    - by Matt
    I have an existing LAN with a DHCP server already dishing out IP addresses. For various reasons I cannot replace that server so it will still need to dish out IP addresses. I've been experimenting with dnsmasq in proxy mode to provide PXE boot filenames. Now I have dnsmasq chainloading iPXE ok, but I found that the problem with dnsmasq is that in proxy mode it won't send dhcp options down. So I can't seem to send option 17 to boot iscsi san. I read somewhere that it's not enabled in the source code. Oh well, so I thought perhaps I should try isc dhcpd (default version4 with ubuntu). But I can't find any configuration examples that work as a proxy. Does isc dhcpd even work in proxy mode? examples on the web imply patching the source. What other options do I have?

  • How do you recommend installing Linux on a computer that has no external drive or ability to boot fr

    - by 7777
    I have an old Toshiba Portege 3505 "ultralight" laptop, meaning it doesn't have any kind of disk drive on it at all, that I'd like to completely reformat and install Linux on. However, it won't boot from any drive (and I don't have any on hand), so I'll have to install it from a USB drive (which I doubt it boots from either). (I'm not sure how to change the settings in my BIOS to get my computer to boot from a USB stick. Any ideas for this?) How do you recommend I do this? I want to note that I don't want to run Linux off a LiveUSB, I want to actually install it on the machine. I was thinking about Damn Small Linux, it's tiny and all I need. Any advice or suggestions for something else though? Finally, I'm a total newbie to this, I've never installed Linux on anything before so I might be a little slow on some stuff! Thanks!

  • Tips on self-learning boot-time fundamentals (grub, disks, partitions, LVMs, etc)?

    - by Harry
    Is there any good resource which I can use to self-learn all the low-level system administration details on Grub, Grub2, disks, partitioning, LVM, etc? I'm comfortable with system admin tasks post-boot but I lack knowledge about both the fundamentals and actuals of all that happens during boot on a Linux system such as Fedora. Any recommendations on how to setup a testbed on my desktop for learning the above? I may not be able to get another machine / harddisk, so may have to rely on something like VirtualBox. But don't know if there are other (better) options... so asking for tips from those who have self-learned / mastered this track themselves.

  • Can someone recommend a Compact Flash card to be used as a boot disk/fixed disk.

    - by Hamish Downer
    I have an early Acer Aspire One netbook, and the flash drive is really slow at writing. I've taken it apart to add more RAM, but I've pretty much stopped using it. I've read about people replacing the SSD with a Compact Flash card and a CF to ZIF adapter but I've also read about some Compact Flash cards where the manufacturer has permanently disabled the boot flag to stop people doing this kind of mod. (Can't find the link any more though). (Although I have just found some info about CF cards that says "Most CompactFlash cards by default identify themselves as removable media instead of fixed disk" and that this is an issue for Windows. So my most specific question is: can someone recommend a compact flash card that does allow the boot flag to be set and to be set as Fixed Disk? Please say whether you've done it yourself, or just heard about it from someone else. Beyond that, is this generally a problem?

To create image I run # xen-create-image --hostname=debian-wheezy --memory=512Mb --dhcp --size=20Gb --swap=512Mb --dir=/xen --arch=amd64 --dist=wheezy After generation finished I start vm and see: # xl create /etc/xen/debian-wheezy.cfg Parsing config from /etc/xen/debian-wheezy.cfg libxl: error: libxl_dom.c:409:libxl__build_pv: xc_dom_ramdisk_file failed: No such file or directory libxl: error: libxl_create.c:919:domcreate_rebuild_done: cannot (re-)build domain: -3 In the /etc/xen/debian-wheezy.cfg i have # # Kernel + memory size # kernel = '/boot/vmlinuz-3.11.2-201.fc19.x86_64' ramdisk = '/boot/initrd.img-3.11.2-201.fc19.x86_64' and ls -1 /boot/*201* shows /boot/config-3.11.2-201.fc19.x86_64 /boot/initramfs-3.11.2-201.fc19.x86_64.img /boot/System.map-3.11.2-201.fc19.x86_64 /boot/vmlinuz-3.11.2-201.fc19.x86_64 Then if I fix ramdisk directive in .cfg file to /boot/initramfs-3.11.2-201.fc19.x86_64.img vm will start but os inside will not boot.

  • How to copy partition from one disc to another (boot partition keeping all the vital data)?

    - by Patryk
    I have bought a new laptop but the HDD, which runs at 5400 rpm, is not sufficient for me. The laptop runs Windows 7 64-bit. I have my 'old' one (a better one - Seagate Momentus 7200 rpm) and I would like to replace it but without reinstalling everything. And there my question arises: can I copy my boot partition from my laptop hard drive to my old drive so that it will boot from it properly? If so, then how to do it? Will Norton Ghost be useful here? My point would be to just replace this partition and leave the rest.

    - by Keith Fitzgerald
    Thanks in advance for your help! As the title states, I have Windows 7 x64 Boot Camp Partition, Snow Leopard on MBP, and VMWare Fusion 2.x/3.x.

Has anyone experienced this? Can someone provide or link a remedy? My google fu is failing miserably ....

  • How do I add xen kernel boot parameters in grub2?

    - by Matt
    I know that I can add command line parameters to the grub2 command line by editing /etc/default/grub according to this answer How do I add a boot parameter to grub2 in Ubuntu 10.10? However, that would apply to ALL kernels would it not? How do I apply the command line parameters to specific kernels? i.e. only xen. I'm wanting to append something like: xen-pciback.hide=(06:00.0) I'm guessing I need to add it somewhere in the file: /etc/grub.d/20_linux_xen Which contains: #! /bin/sh set -e # grub-mkconfig helper script. # Copyright (C) 2006,2007,2008,2009,2010 Free Software Foundation, Inc. # # GRUB is free software: you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation, either version 3 of the License, or # (at your option) any later version. # # GRUB is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

  • How can I boot Ubuntu 10.04 on my MacBook Pro from a USB hard drive?

    - by Daniel Huckstep
    I installed Ubuntu 10.04 to my MacBook Pro (not the latest gen with i7, but one before that) on an external, USB harddrive (GRUB installed to the external as well). When I hold down the option key to try to select the external, it doesn't show up. After some looking around, my understanding is that it won't boot 'unsupported' operating system from an external drive. I have ran OSX from an external when I upgraded my harddrive. What can I do (or is it even possible) to allow my MacBook Pro to boot the Ubuntu drive?

  • How do I boot a virtual machine image from my network?

    - by Haabda
    I have many machines which require the same configurations. My goal is to boot them all from the network and load a virtual machine. It would be wonderful to have one image for all of our customer service machines. That way, I could load the virtual image, perform updates, and know the next time they boot up they will have all the changes. Ideally, the machines would store the image locally and only download a new image if there has been a change. With all the information out there on "desktop virtualization", "PXE booting", and "virtual machines", I feel lost. I have been reading for hours and feel like I have only just scratched the surface. I would like to do this using open source or free software. Any suggestions?
