Ubuntu :: Changing Boot Options For Live CD?
Jul 1, 2010
I am running Lubuntu 10 from a USB drive. Despite this, I believe this question pertains to any other variant as well. Running from the USB drive with a persistent directory, there is no boot options file that I can locate. As an example, for an installed version, the file /boot/grub/menu.lst can be changed to make boot options permanent.
Is there any way I can do something similar when booting from a USB live version? Specifically, I want to add "vga=799" to the options without typing it in at every launch.
Or is the only option for something like this actually installing to a USB drive instead of just running the live version?

I am trying to streamline my boot screen/GRUB Menu. I know what I want it to look like (grub_wanted.jpg), and I think I know how to get it by uninstalling a couple of things, (synaptic.jpg). Now I have too many items on the screen, and it looks cluttered to me (grub.jpg).

I just want to confirm something before I mess with the bootloader. It kind of scares me to rewrite my MBR. It appears that the grub version that comes with Ubuntu 10.10 drives its menu generation from /etc/grub.d/* when you execute update-grub. If I want to put windows first in the list, could I just rename "30_os-prober" to something like "09_os-prober" and run update-grub? My reason for this is every time Ubuntu updates the kernel, it adds 2 new entries to grub's boot menu. It's easy enough to remove these via the Synaptic Package Manager, but that means for at least 1 boot cycle, my default OS gets messed up (Windows). I have to leave it as the default for others that use the computer, even though I prefer Ubuntu.

been trying to get linux installed on a troublesome laptop for 48 hours now without any luck so thought I'd post here as my last option.
I've tried installing 10.10 desktop, 9.04 netbook remix and just this minute 10.04 netbook versions of ubuntu, as well as other versions of various linux distros.
I woke up this morning and burnt 10.04 netbook to CD (not usb) as I wanted to put it on an old laptop with max resolution of 1024x768. I put it in an external CD drive and it boots up to the options screen on the Live CD, where you can choose to 'try Ubuntu netbook without installing' or 'install ubuntu netbook' etc.
The problem is, I can't click (press enter) on any of the options. The same problem arose with earlier versions, i.e 9.04 netbook remix Ubuntu.
Laptop model: Compaq Presario R3000.

I own an HP Envy 14 [url]. Letting Ubuntu (or any Linux) attempt to boot into a Live CD without changing any parameters results in a black screen, but with everything else working (for Ubuntu, that means the login sound is played). I've discovered that putting nomodeset in the kernel line will allow me to get so far as a command line, but I can't startx from here (I get "Screen(s) found, but none have a usable configuration."). I think my issues have something to do with the dual/switchable graphics in my laptop.

So I have the burned ubuntu CD, and I'm attempting to install it on a system that has one HDD with XP/Vista on it, and another that is completely formatted and unpartitioned. However, when I boot to the ubuntu CD, I can use the menus from the bottom, and select the language when initially prompted, but I can't select any of the menu options except for boot from first hard drive.

This appears to be a simple problem, but I struggled my way around google, trying to figure out the right words to search for, with no real success. The problem:When I plug-in any usb device or an external hard disk, my RedHat automatically mounts it to /media/<device_name>. Unfortunately, it's owner and group are both root, whereas, I would like to add other users to have write access (say, all users in a group usb_group to be able to write stuff in it). Currently only read access is there for others. I would like to change it to write access to a particular group and I can add the

I have a 2 TB hard drive in an external USB caddy that I use for backups. The drive gets automatically mounted when connected to F13, which is great, and the default mount options it uses are:Code:rw,nosuid,nodev,uhelper=udisksHowever, I want to add an extra option or two but I don't know where I can do this. Does anyone know where I can add mount options onto the default set?

Been a while since I've been on here, but I was using Fedora 12 for the longest time and only recently started having problems. I kept getting errors and pop-up dialogs telling me to run yum-complete-transaction, which I tried as root many times. It would then give an error that it couldn't locate the repository and such. So, I looked through all my yum config files and changed a few things until I FINALLY got the command to do something, only it did all kinds of strange things as I was running low on EXT3 disk space and using old Windows' partition to store a lot of things on.
Now, I backed up all the /home directories and files as well as /root, just in case this didn't go smoothly and I still ran out of disk space. If I had the money, I'd buy a storage stick and just back up everything, but that's not an option at the moment. Now I have a crippled version of XP (pretty much useless from a trojan, even though I had McAfee AND Windows Defender running), and half of Fedora 12 with 2 different boot images! When I first did this, I used a 10G partition to install Fedora, which was plenty then. What's left of Win still resides on about 65G of space, but I have a lot of files there I want to keep. Fisrst thing I want to know is, should I look anywhere else on the Fedora disk to find files I may need, just in general? There's still a LITTLE space on the drive to back up stuff if I need to.
Second, while I still had enough to work with, I managed to download and burn a F14 Live CD, which is running now. I saw the option on the desktop to install it, and can get my config files and such from the backups if need be. I do NOT have a DVD burner, so if I have to I can use regular 700MB CDs, but only if they are available.The next thing I need to know is if I can install F14 from the web, without having to download any more ISOs, (again, assuming they are available). I know all my DSL settings so that's not a problem, I just need to find out if I can install it that way before I go clicking that icon. Anyone with experience with this would be helpful. I'm ready (MORE than ready) to go through with it, I just don't want to get "stuck" once I start the process. My download rate is around 200k/sec, so it's going to take some time no matter which way I (can) go.

I have an Eee PC with a dead Hdd. I brought it back to life by installing Ubuntu 10.10 on a 16GB SD card. It works 100% but is sluggish.Now I am wondering, from the standpoint of reducing SD card access and writes, would it have been better to create a Live Disc on the SD card with persistence options? What I am thinking is that a Live Disc is designed to run out of RAM, and would thus reduce the activity on the SD card. The only thing this netbook will get used for is the internet. It is a netbook, so the performance is limited, but as far as netbooks go, it is top of the line with dual core and discrete nvidia graphics.

recently I have been trying to create the perfect custom ubuntu .iso to write to a usb drive so i could carry around a live cd version of my current desktop operating system. I have 2 problems...
1: using various tools like Remastersys, Ubuntu Customization Kit, and Ubuntu's own LiveCDCustomization tutorial I have managed to install most of the packages that I want.... Truecrypt is not in the repos and i would very much like it on my custom live cd. while in chroot i tried using wget to download it then extract and install it, but i got a 404 error so it did not seem to be connecting to the place to download it. is there a workaround to getting truecrypt to install into my extracted squashfs? would it be possible to download the packages to my desktop then copy them over to my chroot squashfs to be installed?
2: I have not been able to customize the default appearance of the desktop environment like the background, icons,colors, window border, panels, applets, and so on.... Ubuntu's tutorial states that I need to edit .xmls in /etc/gconf but i do not understand how to edit those to get what I want. LiveCD creates a new user with default settings everytime it is started so its a matter of editing the files that control the settings of a new user.

i have this problem and i may need professional help; it appears smb4k made my /etc/sudoers file writable (according to log), hence, any sudo command will coerce this error:
Code: ubuntu@ubuntu~$ sudo any sudo: /etc/sudoers is mode 0640, should be 0440 sudo: no valid sudoers sources found, quitting i wanted to boot into recovery console and chmod 0440 /etc/sudoers, but it's a live system - it doesn't have a recovery mode. [URL].. How would i mount the live system from another liveCD?

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.

I'm a noob but enjoying dual booting. However, every time I run update manager I get a new vmlinuz entry and now I have multiple boot options in my grub boot menu. Now when I have like 5 ubuntu entries to move past to select Windows. and the latest Ubuntu is always at the bottom so I have to annoyingly scroll down to select the latest there. I don't really understand what the vmlinuzXXX entries in the boot folder are for so I don't want to delete them. I've thought about editing the loop in the 10_linux file in the grub.d folder but it looks like its calling a function or macro or something:
Code:
linux='version_find_latest $list'
But like I said, I'm a noob to all this (a .Net developer on Windows professionally) and don't understand where this is. It looks like this function call has the logic I need to fix. Because its not finding the latest, its just finding all. How to I get back to one Ubunutu boot option like when I first installed?

Here's my current setup:
Disk 0 (500GB): Windows Vista
Disk 1 (1TB): Windows 7
Disk 2 (160GB): Ubuntu
My boot disk is Disk 0. Currently when I turn on the PC, GRUB loads from Disk 0. I can then choose either Ubuntu or Windows Loader. If I choose Windows Loader (also located on Disk 0), I can choose to load Windows Vista or Windows 7. I like this setup, but I would like to move the loaders (exactly as they are) to Disk 1 so that I can format Disk 0.

I have both Ubuntu and Windows XP installed on this computer. This isn't that big of a problem, but I would like to know if there's any way to remove the other four or so boot options for Ubuntu and leave only the 'standard' boot options for Ubuntu and Windows XP. I am new to Linux so I doubt I'll be using those any time soon so I'd like to have them out of my way for the time being.

I had bought a new wifi card(rtl8185) and spent 2 days trying to make it work. I finally got it working but now I am experiencing some other problems.
First of all I get two many bootup options. Before I used to have 4 generic options(2 different kernels with each of them having their own recovery), memtest and then my win7. Now I am having those plus 4 server options and 4 preemp(no clue what this is) options. I am suspicious that this has to do with some command I ran: sudo apt-get install linux-backports-modules-wireless-* I got some notify at that point about broken packages. I followed the instructions given and made the messages dissapear(I don't remember excactly what I did). Then when I saw that it shows all those bootup options I tryied sudo apt-get remove linux-backports-modules-wireless-server and sudo apt-get remove linux-backports-modules-wireless-preemp but that didn't solve anything.
My second problem is that in startup now even if I choose the generic option it doesn't load the gui but just gives me the command prompt so I have to run startx each time. I am kind of a noobie in linux but would like to learn so please give me some guidance. I thought of reinstalling a fresh copy of Ubuntu-desktop but it's just too hard work. So I would be grateful if you could tip me on how fixing the problem as it is. I run Ubuntu 10.04 x64

Is there a way to access the list of boot options from Ubuntu? I don't want to change the options, just have someone access the information, then copy and paste it in an email so I can see what the heck is going on with their computer.
The problem is this:
User has 2 physical drives.
Drive 1 has XP
Drive 2 has another version of XP on it as well as Ubuntu.
We want the computer to have the option to boot into XP on Drive 1 and Ubuntu on Drive 2. Booting into XP on Drive 2 is an option.
We can get into Ubuntu, and XP on the 2nd Drive, but not XP on the 1st drive.

I am using Ubuntu 10.04 x64 in a three-boot configuration; the first boot choice screen (the one I would like to change) gives the options of booting to Ubuntu, 3 options I don't understand, and booting to Windows 7. Unfortunately, at least for me, Ubuntu is at the top and is the default. [The third choice is Win XP x32 - but it appears on a separate screen]
My question: How can I make the boot to Windows 7 the default choice?

my two partitions (ubuntu and WinXP) worked fine, i always had a boot option at startup. however, my Win boot option simply disappeared. I did not do any update recently, so I do not really understand what could have happened. My /media/windows is also completely empty. when i try to open the windows partition, it says "could not mount".

I've recently been trying to attempt to install Ubuntu on a partition on my macbook pro OS X 10.6.6. I have attempted to create a bootable USB stick (as I currently do not have any CD's/DVD's to use). I have followed the guide on the Ubuntu installation page twice, word for word, command for command. Everything goes flawlessly, all the files are visible on the drive when I checked, and I have never received any errors in the terminal. The problem arises when I attempt to boot from the USB, it simply does not appear under the options when I attempt to boot. I have also checked the Start up Disk under system preferences.
I have attempted the installation on two different USB sticks, and the same problem on both, flawless to install to USB, but then it is somehow not booting. I have checked with the USB company and directly from the website it says that the PNY attache is capable of this. It is the 4GB model.

I recently switched my laptop from Ubuntu 11.04 to 10.04.2, and during the process, I used GPARTED to partition the drive so that I could have both versions installed simultaneously while I transferred files and settings and such. A few days ago, I removed the 11.04 partition, formatted and added that disk space to 10.04's /home partition. However, when I boot up, GRUB still gives me the option of loading into the newer 11.04 partition with the newer kernels. How do I remove those options from the GRUB menu? I checked the Ubuntu GRUB help pages, but didn't feel confident that I could do edits without messing up the 10.04 boot settings.

1. I have windows xp on my notebook compaq presario v2000.
2. Wanted to load linux as dual boot.
3. Tried with Suse linux, but there was some blank or black screen problem after installation.
4. Someone suggested Ubuntu linux.
5. Downloaded and burned ubuntu on a cd.
6. But this time during installation during partitioning there was a serious problem.
7. On ubuntu webpage they say for partiioning i will get 4 option, but i got only three options in my cd.
8. The missing option was the most important , which was required for dual boot. " Guided resize and use free space".
9. So i had to abort my Ubuntu installation as using any other option could have effected my current xp installation or might have formated my whole notebook.
10. So any comment why the dual boot partitioning option was absent in my ubuntu cd.
11. Or there is some thing to be activated in my notebook setting to enable dual boot.

I can access the folders that I have created in XP. What I would like to know is whether or not it is possible to share or link folders between the two OS. For example, I try to keep my files organized as best I can and had been keeping pictures in my XP "My Pictures" folder, but have to do a bit of directory digging to get to that same folder from Ubuntu.
