General :: CentOS Live CD Of Current Installation?
Mar 7, 2010
I'm trying to create a live CD of my current CentOS installation. I want it to be almost like a backup, so whenever I want to copy my current installation to another computer I would simply install from my custom live CD.I know this is possible, and I found some resources on the net, but they all seem to only create a minimal version of CentOS; I want to have all the current functionalities available to me at present, including all of my development functionalities, Apache and samba settings, etc.

alrighty, long story short, I screwed up. I had installed a copy of ubuntu 9.1 to my sda1 partition and a copy of windows 7 to sda2 and it worked pretty well, but after needing to change the partitions around, I deleted sda1 and did a wubi install. I forgot to adjust the mbr before deleting the ubuntu install and my live CD is still running ubuntu 9.1 (think that's grub 1.5) and I can't update the live CD, as my only functioning OS is currently running off it. I suspect, therefore, that the mbr is still pointing to a now non-existant partition to find the boot files. So, in short, how do I use my current live CD to allow me to boot into windows in this situation? my current partition table is sda2: windows 7/wubi, sda1: media/backups

I was just wondering if there is a way to capture current state on a machine and create live cd from it?
If not - what is the best way to create Live CD with optimazied system updates and configuration packages.

i'm using centos 5 and i want to save my setup when switching the user.when i switched user from user1 to user2 and then i logged in user1 back without shutting down, i couldn't see any working window on user1. But since it's working on the CPU, i guess it's working but i cannot just see the window(such as terminal in my case) i was using. i have been using scientific linux which have "save current setup" when logging out. but centos seems not to have that check box!i want to know whether centos can contain the setup for each user when switching user.

Is there any sure-fire way to identify whether the current Ubuntu system is running in Live mode or not? I want to distinguish between Live mode and running from installed HD, and do some processing in boot up script. FYI, in grml, the /etc/grml_cd file only exit in Live mode file system; no such file if running from installed HD.

I have got an Notebook whose CPU is 64bit.The Notebook has an CentOS installation. Now I want to find out if this CentOS is 32bit or 64bit.How can I check this?
uname -a
gives something with ....i686 i686 i386...."
What does that mean?Does that refer to the hardware or the CentOS OS? An 32bit CentOS can be installed on a 64bit hardware!I am interested in the OS capability not of the hardware!

I have XP currently installed on my work machine, which is getting a bit outdated and sluggish. I was hoping to install Ubuntu 32-bit through Wubi and use VirtualBox to run XP.Would it be possible to mount my current XP installation?Would this even be advisable in order to speed up the XP applications I need to access?

Half of my hard drive is an unused partition, which is formatted ext2 which is just temporal and has no specific intention of mine. This unused partition has its own swap area, which is also a temporal and not important.
So my HD is:
Now, I'd like installing Windows 7 using these sda2 and sda4 partitions without corrupting current Linux installation and its GRUB2 setting(I'd likt to reconfigure the GRUB2 after successfully installing the Windows image, for the dual-boot).

I've done a good few ubuntu installations for friends and colleagues and now my Dad wants in on the action. His PC is more than capable of running ubuntu 32 bit BUT I've hit a brick wall I've never come across before. I've burnt a CD image of the 10.04 iso from [URL] on my ubuntu box and for some reason, his PC just won't boot from it. If I select the option to manually select the boot source, all I see is the hardware monitor telling me things like CPU temperature. As for the Live USB - nothing whatsoever. Is it possible that I've managed to corrupt the iso file somehow?

Live CD: I dowloaded the ISO, burned it to CD, booted from this CD. It starts to load and I can see the purple background with the loading icons. Everything seems normal. But instead of ending up with the login screen, it ends up with a screen that says 'Please remove all bootup media and hit ENTER' or something like this. So I hit enter and then it shuts off my computer. That's it.
Live Stick: So I tried another option and created a stick with 'usb-creator.exe' that is on the CD. Then I start from that stick, but all I end up is a line of 'Syslinux bla bla copyright 20xx-2011'. That's it. Then it does nothing anymore. The cursor is blinking, but no prompt or whatsoever and keyboard input doesn't do anything.
Now something weird: When I insert Live CD and Live Stick at the same time and then boot my computer, then it boots into Ubuntu. Obviously it loads the first parts from CD and then the rest from stick. Because when I'm then in Ubuntu and try to format the stick, it says it can't do so, because there's system files from that stick in use.

I just ran "yum update" to download the latest kernel from the repository, and noticed that it's 2.6.18-164.11.1 while the latest on www.kernel.org is 2.6.32.4.Out of curiosity, why is there such a discripency between the two? Lack of resources to test and build binaries?

I am trying to port the current Fedora4 system to the CentOS5 on a new hard disk. Actually, the Fedora4 system is constantly being hacked due to my lazy update. So i prefer a fresh install of CentOS5. I am not clear what files need copy and what does not need for ease and for avoiding possible backdoors.

I want to dual boot Fedora 11 and Windows Vista, and the last time I tried I deleted my Windows Vista (big no no). So, I've made a partition of about 30GB, and I'm trying to go through the installation (from the live CD), but I don't know quite what to do? If I select Shrink existing disk, it doesn't let me do it for any amount that I put in, by the way.

I just downloaded OpenSuse 11.1 64 bit live cd from it's official site.I have live usb creater in my xp box , with the help of which I successfully created live USB for fedora 11 earlier. Now the problem is whenever I try to create live usb using Opensuse live ISO image after extracting all files to usb , it gets failed.The same thing is happening with OpenSolaris 11 live cd iso image. Does this mean that live usb creater I have, was only foe Fedora distros?

I installed Ubuntu Lucid Lynx a while ago. but then upgraded it to 10.10
I don't have the CD with me right now and i need to fix some mistakes of mine (being a n00b to ubuntu) urgently i.e. i can't wait for morning. Is there anyway i can rollback to the time when my ubuntu installation was in mint condition?
One more thing. Let me tell you my mistake. Almost a month ago i installed Apache2 on my Laptop (for LAMP). and now i have to install Apache Tomcat for JSP development. but the problem is that the files made by Apache2 and the PHP5 installation i made are not removed with
Code:
Code:
So now the apache2 files are superseding the Apache Tomcat. hence i cannot distuinguish between apache2 or apache tomcat when i goto:
Code:
So if anyone has a way of ridding my laptop of this disease without complete overhaul, please post your replies here.
Until then, I will have to defect back to Windows.

I want to install Ubuntu 10.04 to another machine alongside that other machine's XP. I know I could just run the install disc; but I'd like to take what changes I've made to Ubuntu along with it - for instance, TrueCrypt, Simple Backup, AdobeReader 3 (I think that's an addition), K3b, MuseScore, and some other applications I've added along the way. Also, I went thru some Terminal commands to get Brasero to copy CD's recently and would like to avoid doing that again.

I am going to set up Linux on a USB Flash Drive and want to either install to the drive or run a Live Distribution from it since I want to stay with the distro I have on my hard drive.What size or type of drive should I use? I have access to a Corsair Voyager 16GB. Is 16GB enough and would the speed of it be enough?I have seen other drives such as the OCZ Rally 2 which have faster write and read speeds.
