CentOS 5 :: Booting From LiveCD - No Install Icon?
Jul 30, 2009
Coming from Windows. First installed Fedora 11 but lost network and haven't been able to restore network connectivity. Attempted to re-install but during the boot process it complained about creating a soft link to /dev/root (not sure what this is about). So attempted to install CentOS by booting from the LiveCD. Much nicer interface but have no install icon and there doesn't appear to be installation guide. How I can install CentOS?
I downloaded the CentOS-5.6-i386-LiveCD.iso and burn it on a CD, as usual. When booting, it does the automatic boot but then crashes, with "Buffer I/O error on device sr0, logical block 354800 (and more)". I am having the same problem with making a boot-able USB. I am not exactly sure what is wrong, I see two folders on the cd LiveOS and isolinux. I'm not sure if it is suppose to be like this, if the burning process when ok. I'm trying to set up a desktop on a pc (with AMD Sempron processor). This is very strange, I ruled out that it couldn't have been my computer (because my Fedora boot disk booted fine), my cd (because it is new and an entirely different brand), or the .iso (because I tested it in VirtualBox, which it booted perfectly).

-I could use a hand in installing opensuse on my 2009 Intel Macbook
-I need to use a USB stick for the install, my optical drive doesn't work.
-I am trying to reformat my macbook to run 64-bit opensuse 11.3 instead of Apple's proprietary operating system, OS X
-So I started here: Chapter1.Installation with YaST
-And in this article, under section 1.1. Choosing the Installation Media, i found this sub-section: Booting the LiveCD from an USB Stick.
-So i followed those steps to create a bootable USB stick in Terminal, and i got an error in Terminal and was unable to go any further;
-this was the error in Terminal: dd: bs: illegal numeric value
Would anyone know what the error means, and what i should have typed instead? Is it because my USB stick is generic instead of being a specific type like a U3 stick?
I have been trying to create a live CD or DVD with kiwi, and following the instructions from Portal:KIWI - openSUSE All went well with the building and creation of the ISO image, but when I try to boot it I get:
Failed to mount ext3 clic container Failed to mount root filesystem if I press Alt-F3 (suggested in the terminal)the top most error is tune2fs: Attempt to read block from filesystem resulted in short read while trying to open /read-only/fsdata.ext3 Couldn't find valid filesystem superblock. Something I did find was that it may not have permission to use tune2fs.I haven't done any fiddling with the template supplied with kiwi.
I am getting a "No devices matches MBR identifier 0x8c71ad6e!" message along with a reboot in 120 seconds message. This occurs after kernel load and at the start of openSUSE boot.
I have checksum checked both images after download. I have attempted the install on CD and USB stick with both images and the result is always the same.
I've included a screen image on my site: No Devices Matches MBR Identifier | Badzilla
I recently had to reinstall windows on another partition on my hard drive due to there not being any good way to run unrealed under ubuntu (believe me, I've tried everything) Is there a way to install grub from windows without using a liveCD or booting to a USB? I have downloaded WINGRUB and to be fair I have no clue how to use it.I no longer can access my Ubuntu partition.
I'd like to download Cent 5.6, but I'm a bit confused on which ISO I need to download. I can't use any of the torrent files since my company FW won't allow it through. So, should I download the Live CD or ISO 1 through 8? Can I install the Cent from the LiveCD? If I decide to download ISO 1 through 8, how do I then combine them?
This might sound like a really daft question but how the hell do I install CentOS 5.5? I cant find any guide how to install the dam thing. I ve downloaded "CentOS-5.5-i386-LiveCD-Release2.iso" & burnt this to a CD. I then booted my server form this CD. I see a very nice colourful screen which says "Automatic Boot in 10 seconds". After 10 seconds nothing happens. I then rebooted the server & this time I hit the enter key, I now see a menu with the following options:
Boot Boot (text mode) Network Instillation Memory Test Boot form local drive
If I try the "Boot" or "Boot (text mode)" options nothing happens. Selecting the Network Instillation appears to boot the install I then see a blue & red screen asking me to choose a language I picked English hit OK selected UK as the keyboard type hit OK Installation ethod...... Ive chose Local CDROM but the message says: The CentOS cd was not found in any of your CD drives.
for the past couple of weeks, I have been booting from an Ubuntu LiveCD. Here's why: When I boot my computer (emachines E528 laptop), it gets to the BIOS loading screen (the one where you have the option to press a function key to get to the BIOS settings), then it goes to a black screen and looks like it is going to load GRUB, but instead of loading GRUB, the computer reboots. It does this endlessly, unless I insert a LiveCD. So, it's not the BIOS. That's good. When the Mint GUI (Linux Mint was the LiveCD I was originally using as I just happened to have it on hand) loaded for the first time, I checked all of the hard drive partitions and they all seemed to load fine. So, it's not a mechanical problem with the HDD. That's good.
At this point, I figured the MBR had become corrupted somehow. Now I wasn't really sure exactly where the MBR was, or how it all worked, but I was pretty sure that if I just reinstalled GRUB, everything would be hunky dorey. Unfortunately, I hit a road block when trying to install GRUB. That's not good. I am trying to follow the instructions in this thread, but I get the following error:
Code: grub> find /boot/grub/stage1
Error 15: File not found So then I tried following the instructions here, but I don't know how to tell which drive is sda1, sda2, etc. I'm guessing there's some terminal command to figure it out, but I don't know it and Google was less than helpful. I feel like something that basic should be easy to find, but I digress.
At this point, I am getting very close to backing up everything and reinstalling everything. Only problem with that is that I am not sure how to access the files on my Ubuntu partition as they are encrypted (I wrote down the key when I started it up, I just don't know how to bring up a prompt that will let me enter the key). I really don't want to reinstall and set everything back up, but if I have to I will.
So, I guess I just need to know how to tell which partition is associated with which sda#, or how to access the files in my encrypted Ubuntu home folder, or (hopefully) someone who can tell exactly what's going on from why I have posted and can give me instructions for fixing my problem. Also, here's a breakdown of how my hard drive is partitioned. Not sure why, but I thought this might be helpful: linky.
TLDR: How do I tell which partition is associated to which sda#? How do I open my encrypted home folder from my Ubuntu partition? After reading my whole post, is there any further insight you could offer that I may have overlooked?
Is it possible to make a personalized version of ubuntu livecd that autostart ssh after booting? I need to test if video card failure cause my computer to freeze.If that's too complicated or not possible, is there any other livecd that does that?
I just built a computer with these specs: Asus P7P55D-E Pro Mother Board 2 x 4gb GSkill RipJaw 1333 Intel Core i5-760 cpu MSI nVidia GeFore GTX-460 Video Card
When I try to boot from a live CD/USB I always get some sort of kernel panic, most times about USB controllers and other times about cpu_idle. I have pictures of these that I can post but nothing from any logs because this is happening even before I install. I have left memtest running over night for 11 hours and had no problems, I have tried to boot with only one stick of memory, I have changed the video card to a GeForce 8800 and I have tried everything on a different motherboard and still no luck. Would I wrong to say that there is a problem with the CPU and should I return it? My only problem with all of this is that Windows installs perfectly fine on the computer with zero problems...weird.
I have a system without a cd reader so i dd'd the livecd iso (I'm stuck with 7.10) to a partition. I can boot the system with grub4dos by loading the kernel and ramdisk. Is there a kernel parameter I can append so I can change the keymap like I was able to by pressing F3 in the cd boot menu?
I've done some installations and configuration of linux systems for different needs and I've never had such a problem:
* The system is Supermicro X6DVL-G mainboard with two Nocona Xeons @ 2,8 GHz, 2 GB DDR333 RAM, 2x160GB Seagate ST3160827AS SATA HDD, ATi RAGE 128 VGA and an external LG USB DVD drive.
* The role of this machine will be Joomla Web/Mail/FTP server for my company's website
I've tried FreeBSD, PC-BSD and now CentOS 5.3. The BSD based OSes installed and ran with no problem but I had trouble configuring them and I decided to move to something little more familiar. However the BSDs didn't detect the integrated Promise RAID controller but CentOS had no problem with that. After some fight with the initial setup I've managed to made it recognizing the external DVD and install the OS. I'm using the whole stripe for the OS, leaving the linux to determine and create the partitions. The installation went smoothly with no errors, but after restart I get the POST messages and then... NOTHING! No error, no panic, nothing, just a blinking cursor. The first thought, confirmed later by several posts I've read, it's the integrated RAID controller making the issue.
Well, I removed the stripe, disabled the controller from the BIOS and installed again, this time with the two separate disks - the sda is bootable with swap and ext3 and sdb is spare with ext3. THE SAME... Third time - only sda is configured for istallation - again NOTHING. Fourth time - sda is configured for installation and No Bootloader option is selected - SAME.
I have a NVIDIA Geforce 6150 LE video card and it is on the motherboard. I vaguely remember something on some site about nvidia cards, but can't remember what. It gets to the part where it says something like "Boot Ubuntu from the CD." I hit enter and it shuts my monitor off.
I have a Dell Studio laptop, which I am trying to make dual boot and in big trouble. These are the steps I completed.
1. Backedup all my important data on a USB drive. 2. Prepared a Ubuntu LiveUSB and booted in Ubuntu. 3. Used GParted tool to repartition my hard drive (320GB) as follows,
4. Accepted all these changes in GParted and restarted the machine. 5. Used VISTA installation disk to start VISTA installation on 1st NTFS partition (Partition 1).
-Everything was fine until now -
6. The VISTA installer took a really long time (around half hour) just showing copying files with 0% completion status message. 7. Somehow I got impatient and tried to cancel the installation.
Now, the problem is the system does not boot up even with my USB LiveCD or Windows VISTA installer. It just shows blank screen and nothing appears.
My DVD drive has gone bad and with new Fedora 14 just launched I decided to install the same through the usb flash disk.
First I used dd: dd if=/home/prabhat/Download/Fedora-14-i386.iso of=/dev/sdb
It went on nicely and copied the iso nicely. But I could not boot with it.
Second time I tried livecd-tools: livecd-iso-to-disk /home/prabhat/Download/Fedora-14-i386.iso /dev/sdb1
It went on nicely, and finally declared something like - usb disk is not live .... But here again when I tried to boot it says MISSING OS. I checked the contents of the flash disk. It contained raw DVD iso image, one images directory, one syslinux directory. I checked the contents of the images directory, and I found it had the install.img. And yes, the /dev/sdb1 is bootable.
I am attempting to set up an IBM Intellistation Z Pro to optionally boot from many OS versions. One of these is Windows XP. Windows XP is currently installed on a RAID 1 device consisting of a pair of 1 GB WD drives. These are SATA drives. The HBA I'm using is a SYBA SATA II card that uses Silicon Image's SIL3124-2 chip. The card has a BIOS and I've set up two 60 GB mirrors for Windows. I boot XP fine from this setup and things run good.
I've downloaded the CentOS 5.2 images and am able to start the installation process. I'm baffled on where to install the OS software on the RAID device. The installation process shows the two 1GB drives as separate drives and there is no acknowledgment of the 60 GB partition I've already created on them for Windows XP. I expected to see only the one logical RAID device and 60 GB of it in use for a NTFS partition. Reluctant to proceed further, I bailed on the install and am asking for advice on how to proceed.
The big question is
1) How can I install CentOS 5.2 on the RAID drive to coexist with a Windows XP installation? My desire is to boot either from this drive.
other questions related to this are:
2) Why does the CentOS partitioning software used for the install not display the logical RAID drive set up through BIOS (I'm assuming that this means it was set up apart from any Windows drivers etc.)? Only the two physical drives are displayed and there is no mention of any partitions in use.
So my company just bought 2 mtbs with G31 + ICH7R chipset, both same model. Also they have 4GB Ram each with 2,5 - 250GB HDD Core 2 Duo E7500 CPU The first one went fine through the installation and it' s up and running while the other one, no matter if I use linux text linux text noprobe linux text dd noprobe irqpoll either in 5.3 or 5.4 x86 or 64
It starts booting and video just goes off, no error messages at all. Tried to install using the other motherboard, went fine, with hdd installed and working, it does the same thing, shows the Centos menu loading, start loading and video goes off.
I'm trying to create a CentOS based liveCD that mounts a NFS share and executes one script there. The NFS never mounts altough while logged I can mount it with the very same command that I use in the KS.
In the %post I have :
%post --log=/tmp/post.log --erroronfail mkdir /mnt/nfs mount -o nolock 10.23.1.1:/csc/RemoteHome /mnt/nfs
I added the --log in order to debug, but nothing is written in /tmp/post.log. I tried redirection on the mount command with >> /tmp/debug.log but this is not written. Maybe during the post sequence /tmp is RO ? Anyway, I tried with ifup lo, service portmap start in the %post, but doesnt change (I even have a service : command not found in the live cd creator output).

Im trying to set up a CentOS 5.1 LiveCD on my PXE/tftp server and am having problems. I can currently successfully install CentOS 5.1 using my PXE server but can not get it to load the Live CD.
I tried following this How To but it doesnt cover a Live CD just a rescue mode.
http://wiki.centos.org/HowTos/PXE/Rescue_PXE My entry is /tftpboot/pxelinux.cfg/default for the live cd is this:label centoslive kernel centoslive/vmlinuz0 append ks=http://ip.to.liveCD.contents/CentOS/5.1/ks/live initrd=centoslive/initrd0.img ramdisk_size=8192 selinux=0 text
In my CentOS Bible, written by Timothy and Christopher it refers to a one button that you can install CentOS with one button from the LiveCD, or from CentOS running from the CD and install to the hard drive? I pressed everything and nada, as most everything does not function it seems. What am I missing that may go along with preparing these Dell 2650's?
I have centos 5.5 on vmware, and I'm trying to boot up from the live cd so that I can fix some issues that I'm having. I have vmware pointing at my cd drive, I mount the cdrom and when I ls, it lists the contents of the cd. But when I go to reboot centos, it doesn't boot from the cd and just boots normally.
I checked a couple of locations:[URL]... and none of the files listing checksums do so for the LiveCD ISO neither md5 nor sha1. Being a "trust but verify" sort of fellow. . .
I using only Livecd CentOS 5.4 and my system crash in day about ~3-5 times , so I tired and want to know why this happen. (before I used live-cd 5.3 about 3 weeks and this problem still was. info : Linux livecd. localdomain 2.6.18-164.el5 #1 SMP Thu Sep 3 03:33:56 EDT 2009 i686 athlon i386 GNU/Linux.I load system perfect and If I just browsing then I will have crash after 5 hours latter , but if I install wine , xmms,lame,xmms-mp3,k3b-mp3,flash-plugin and after installing software I will look movies from internet , or lisining music on xmms mp3 format - my system UPTIME max will be ~30 minutes or less..And I want to ask, or in Live-cd I can start Firewall ? Becouse I think it's not started and then I try to ENABLE its looks like not responding.
I followed the instructions here: [URL] and then here: [URL] and installed the necessary packages. But when I try building the minimal image as a test, I get lots of errors, as seen in the attached build log. There are lots of things that don't seem to work. Is this project at a state where it's not currently usable? Or do I have a problem with my system configuration? I was running at root.
