I am having trouble botoing into live system. Lubuntu 11.04 boots to command line. I am trying to boot from a CD at computer that is currently running Ubuntu and Xubuntu 10.04. I can see the dots on loading and also on shutdown but i can't start the X.Computer is an Old compaq presario 731EA, S3 graphics card with 256 MB total ram (32MB goes to graphics card). I tried nomodeset but same thing happens.

For an older computer that won't boot off USB (like the live knoppix/ubuntu, etc) , is it possible to have it boot off of a special CD that will tell it to run the operating system off an attached USB thumbdrive?

She clicked yes to install upgrades, but at some point during this process the machine froze. She restarted, and I haven't been able to successfully boot since then. the final screen when trying to boot from the hard drive reads:

I'm slowly getting the hang of Ubuntu. By now I know enough that a Live CD can fix most problems. So that's where I went after doing several searches about the error messages that were appearing. The menu screen works, but I can't get it to boot into the "Try ubuntu" mode. I tried changing the boot parameters to no avail. As the boot tries to load I can see a line by line report of errors- some are I/O errors and are in white, but many were in red, which seems bad from my mostly ignorant perspective. I saw lots of SQUASHFS errors among other things. I took a snapshot of the screen that was displayed when the boot failed- it's attached to this post (lots and lots of text to be typed otherwise). The reason I know it failed is because I've tried a half dozen times with the same exact result- once I let it sit for an hour+ just to make sure it was really frozen (a bit optimistic).
Relevant info: Ubuntu is running on a Dell Inspiron 8600 laptop. I think it's version 9, but could be 10. The Live CD I'm using is version 10 burned 1/4/2011. I'd be thrilled to hear any suggestions that folks might have.
I am researching how to make an effective backup on Ubuntu Server. This server will have Vsftp, VPN, Samba stuff , many other added packages +many printers, many users + data. I know I can use tar for the data /u no problem. 1. I was testing tar on the /home directory on a few user directories. I then created a new directory and did a restore of the users directories on it. I noticed the /home/user owner and group were root. The files in each directory remained the same. This gave me concern. If I had a crash and had to restore these to a new HD. I would have to change these, what else would I need to change? 2. Since I have many config files, how do I back up them? I know I can do a dump, but then users shouldn't be on the system. The system files will change as they add users, printers, etc, and asking users to not work, is not really an option while dump is running. I thought I could do a tar on whole system. (cron late at night .. not as many users) Then in event of crash of HD.
1. Boot from live cd
2. format the new drive
3. tar back in the whole system
Will this work right? Is there something I am missing?
I have been frustrated attempting to get Grub2 to boot a Debian Live system from hard disk. Have set aside a 4gb partition /dev/sda1 to contain the Debian Live and some other recovery tools. I actually have them all working from a 4gb USB stick successfully, but getting it to work on my HDD has proved challenging. On USB, I have PartedMagic, Gparted, Grml, and of course my standard 6.01 Squeeze. I have also managed to get the Debian Live booting from that USB stick. Very slick.
However, I can NOT get Debian Live to boot from my HDD; altho all of the others above boot fine. Have tried it two ways - one using an iSO image, which is how it is done on my USB stick. The other attempt is to copy the entire contents of the ISO to a directory.
Here are my directory structures:
debian_live_gnome_squeeze_i386- contains the following: debian-live-6.0.1-i386-gnome-desktop.iso initrd.gz initrd.img vmlinuz which is how it is laid out on my USB stick debian_live - contains the files from the ISO image The error I get is something like "panic unable to find live filesystem" My grub.cfg snippet for the two methods I have tried - the 2nd menuentry is similar to how it works on the USB stick.
menuentry "Debian 6.01 Live (on /dev/sda1)" {
insmod part_msdos
insmod ext2
set root=(hd0,msdos1)
[code]....
Probly don't really need to get it working since PartedMagic can do almost everything I need for recovery and I can use the USB for reinstall or whatever else.
I've made a Live CD of version 10.04 on a machine running 10.04 (amd64). The disk boots fine on a 2nd machine but does not boot on the machine that created it. The CD/DVD is new and works for other things so I don't think it is this. The Live CD gets to the ISOLINUX screen but instead of "Loading" the screen goes blank and the system shuts down. I've tried everything I can think of (the disk works fine on another machine).

I was trying to figure out how to use Synaptic to fix some dependancy errors I was getting, and set it to remove a certain package. It said it had to remove other packages as well to do this, well that ended up being Gnome and a whole bunch of other stuff. Silly me.So I was alright without having Gnome and went back to writing simple c++ from this book. I wrote a program to output a range of numbers and ran it but had written it wrong, so it would have ran on for hours. So I just killed the power and tried to start the comp again.
This time after the Dell boot screen it would tell me my system battery was low and strike F1 to continue or F2 to enter setup. Hit F1 and Im told that a file wasnt found and then it goes to the Ubuntu loading screen (The logo and some dots underneath) and then a black screen. Nothing else.I figured I needed to reintall and dont have any CDs so tried to make a live CD and this time when I try to boot from USB device get a "Missing Operating System" error.Its set to boot from USB device before harddrive. Need to know what to do to install again/recover old install.

View 2 Replies View RelatedI got BT's repo's set and ready to install, tho I haven't installed them all just yet cause I not wanna crash the system, so I guess what I am asking has anyone sucecfully done this and what are the specific risks here. I have uploaded crunch and that works fine if I do it manually from the command line. the kernal seems to be update-able as well to BT's Kernal, I am not sure if I should do this or not in fear it might crash the Ubuntu system somehow. I guess what I might do next is install everything but the Kernal and install the executable links to the drop down menu by hand per the menu structure.
What I would ideally want is to have all the functionality of BT in Ubuntu which is pretty close to where I am at. Also, when I am done I want to make a live CD of this system so that I not have to do this ever again as it is very time consuming. What program would be used for that? Would any of my user data transfere? I don't want my user data to be transferred to the live CD just the raw system data etc. Anyone done this and would like to chat via skype? that would be best, but I'll take any help I can get at this point. I am using Ubuntu 9.10 for all this.
I was playing a bit with a 10.04 live cd and persistence on a small usb stick. I did that on a HP Probook 4510s with windows 7 installed. Testing the persistence, I changed the desktop background and tried to install a small package, about 14MB extra space was reported to be used. My usb stick is 512mb. Suddenly it says there's no more space. After that I rebooted with persistence and half way through loading it stopped saying there's no more space, again. I decided to call it quits and reboot it back to win 7, but doing that just left me with the message "missing operating system". I have no clue as to how it happened, since I did nothing with the hard drive.

My system won't boot because the contents of /etc/fstab, while semantically valid, are not meaningful in my system - neither / or /home is defined, for example.For this reason too fsck will not run.
The grub menu displays OK.How do I rebuild fstab?How do I get permission to change any files on my system when using the Live-CD? Right now all attempts are stopped with a 'permission denied' message.
I just installed a new driver from the Realtek site for my wireless chip, and it broke my system. Ubuntu won't boot in normal mode or recovery mode, and I'm sincerely hoping beyond all hope that I can avoid reinstalling the system I just got working yesterday.
At my connection speed, it will take about two days to download all of the packages I use. Is there any way to get rid of this driver and restore my system back to how it was... about twenty minutes before I posted this, without booting in the system?
We have an old server running, and I decided to run fsck.ext3 -n on the disk to check it (while it was running). Turns out it reports lots of errors - not a good thing.
The weird thing is that when booting up a rescue cd and running fsck.ext3 on it, it says there are no problems with it. The filesystem is marked clean. Forcing a check with -f turns up nothing.
Now, when booting it from disk, fsck complains about an unclean file system that has not been checked for like 50000 days (obviously an error). Running e2fsck -n /dev/sda2 turns up errors again - not necessarily the same ones as the last time.
This makes me wonder: Can running e2fsck on a mounted file system cause errors? I ran with -n which is not supposed to do anything, just doing a read-only check. On the other hand, I heard checking a live file system might throw erros since the files being checked might change while bign checked, thus causing false positives.
Can the old version of e2fstools (1.38, approx 2005) mean non-existing errors are shown? Both the rescue cd and the system use this version.
In any case - why would the file system report errors on boot-up when the rescue cd just said it was ok? It should have been marked clean by now.
For laughs, I shut down the system and booted Knoppix which has a quite recent version (1.41.12, May 2010) of e2fstools. It showed no errors on the file system.
What do you think - are there errors or not on the file system?
The system is actually running Suse, but this is not about Suse specific things - just general Linux tools. And I use Ubuntu personally.
I am new to linux, but need to do the following:
1.) Use a basic ubuntu 9.04 distro
2.) On boot run an existing .sh script
I would like to make a thumbdrive with a live cd version that will auto run to desktop and execute the .sh script. I am looking for pointers on accomplishing this. I have found ways to get the live cd to run on USB, but it still involves clicking the "run without changing your system link" and I cannot figure out how to run the script on start up.

View 1 Replies View RelatedWhat i really need to know is if there is a way to access a Ubuntu file system on a hard drive from a live CD. When i acess it now it just shows the Windows files on it, and i cant access the Ubuntu partition. What happened was this: I was trying to install Ubuntu on an external hard drive. I moved all the settings to the Hard drive so i didnt think it would affect my other drives. I mustve missed one of them because insteading of loading GRUB like it normally does, it came up with GRUB error 21 and did nothing. I tried to fix it, but nothing worked. I finally decided to unplug everything except the external and install it from there, so id atleast have a functioning desktop. As it turns out, my comp doesnt suport USB booting. So the only way i can use my computer is by Live CD. I was trying to fix things so i had both hard drives power supply unplugged. being slightly drowsy from staying up late that night, I plugged them in while my computer was on. the first one went in just fine, no problems. The second one though, also my master drive, i was having troubles pluging in. while i was turning it to fit in, it made a big spark and shocked my master drive. That drive had my MBR and Windows on it. Now It cant find a MBR, and i cant access the ubuntu partition on my slave drive. Is there any way to save this?? im 99.9% sure ive screwed myself over hardcore epically, but im hoping to save at least 1/2 my data.

View 1 Replies View RelatedI have a dual boot machine with WinXP/Linux Mint on it. I am looking to erase both of them and put up Ubuntu 11.04.
I have chosen to go with a live USB install for this. The live USB boots fine and everything seems usable. However, when I tried to install it would tell me that I do not have 4GB available for the install which seemed a bit weird since I have a 160GB Maxtor HDD.
After digging around a bit I realized that the system does not see my hard drive. Running fdisk -l would only show the USB drive that I am booting from and not the main HDD.
I tried to have a look in /dev to see if my HDD is there and not mounted. But aside from sda which is the USB I did not find an sdb or hd entry.
Has anyone encountered a similar problem while trying to install Ubuntu 11.04?
P.S.: The HDD works fine, I can see it in BIOS and in the other 2 OS-es that I have installed.
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.
View 3 Replies View RelatedI have a laptop I don't seldom use, which I want to reformat. I decided the best way to do this was to put Ubuntu on it, since I really just need it for web browsing and a bit of downloading, but I can't seem to do it.
Every time I put in a Ubuntu Live CD, it doesn't load at all (which I assume is an issue with the laptop), so I mounted the ubuntu ISO onto a flash drive, and tried to run it off there.
That worked fine to start with, but I could only get as far as the first menu, I couldn't actually get into the live CD to install it, and I can't think of any reason why.
From some reason I cannot boot from a livecd. I was able to load the vmlinuz and the initrd.img from the cd. The CD even got to "ready.".Nothing happened after this. This is with a liveCD and a liveUSB.
