Ubuntu :: Booting Various Iso Images From Usb?
Mar 24, 2010
I've searched for answers in google, but get not i wanted. I wanted to prepare bootable iso from usb under Ubuntu. Fine, there's UNetBootin, dd if= of= command etc. But I am concerned and the specific type of iso images booting - AntiVirus rescue cd's.
Using UNetBootin i could only prepare thumb drive to boot Dr. Web Rescue CD, but neither Kaspersky Rescue Disk nor F-Secure Rescue CD couldn't be preapred well (NOTE that my BIOS can boot livecd from usb drive!). Using dd if= of= command also didn't worked, cause prepared thumb couldn't boot - get errors: "Missing operating system" or "Could not find kernel image: linux". Is it that i must install grub/lilo or syslinux on thumb, then edit .cfg file and then copy image, or what? I'm concerned only on AV Rescue Disk's, like: Kaspersky, F-Secure, GData Boot CD, BitDefender Rescue Disk etc. I've booted (and it worked) Symantec boot cd but it's based on WinPE and i had prepared thumb under Windows 7, so it's a completely different story.
I have Bootable USB Drive Assistant in my Ubuntu 9.04 but when i try to choose some of those cd's, i get error that "It isn't installable CD image, so application can't use it" or something like that. What application do i have to use then?

I work with many different PCs with Windows XP and Windows 7 deployed, and I'm trying to consolidate my stacks of CDs into a single USB drive. I'd like to be able to boot off it and have a choice of a few options: A persistent Linux install for troubleshooting, the Win7 install CD, and the WinXP install CD.
I'm aware that most USB sticks can't be partitioned, but after much trial and error I've found one that can have its removable bit flipped, be treated as a USB hard drive and partitioned. I can set up 4 primary partitions and an initial test with a boot cd image on the first partition seems to work on 3 of my 4 home PCs... on (only) one of them though, Grub gives a 'Missing MBR-helper' error. All my systems, even the one not booting correctly, see the partitions as valid in both Linux and Windows, and I've successfully retrieved data from all of them. My guess is that it's a BIOS quirk on that particular machine, but it puts the whole idea in jeopardy... if it doesn't work on one of my own PCs, who's to say it will work on other PCs?
I'd like to salvage the partition idea if I can, maybe someone has run into this before... But if it's just not feasible, I read that Grub can boot image files under certain circumstances... I'm wondering if it's possible to have Grub (or any other bootloader) run the Win7 and WinXP CDs as image files? That way they could all sit on a single partition on the USB stick.
I haven't yet tried any other bootloaders, for all I know I could try something else and get things going.

I am running Linux from a DVD, not installed. I am not good with installing software, but since the DVD cannot be corrupted, I am content to operate this way. Lately, I have been having problems that previously did not occur. When I try to click on the checkbox to get rid of emails, it doesn't register in most cases, or when it does, I am clicking multiple times so it registers twice, meaning it is unchecked again. Even more frustrating is some issues that are affecting my ability to update my business. I am trying to modify spreadsheets (text not calculations).
Whenever I try to click & drag to select something to change, it keeps jumping around to select only some of what I want, something else or some combination of the 2. When I try to copy and paste several fields from 1 column to another, everything from the several fields in the source column ends up together in the last field in the target column. I am also trying to download some images from a website. There is a single column of links to the images. I have to click on the link to get to the image in order to copy it, then back out to continue looking for more links to do the same.
My computer keeps jumping back 2 steps, then forward 2 steps, and sometimes I lose my place in that list. I could deal with it if it were a small number of links, but this is a list of probably close to 20,000 links. Again, i am operating off of a live DVD so this should not be corruptible, but this has just started happening, and has been an issue the last several sessions.

I know that ImageMagick's convert program can be used as follows to convert a collection of images -- say, in PNG format -- to a PDF file:
convert *png output.pdf
The problem with this is that each image is then stretched to fit on one page, whereas I would like to keep the original dimensions of the images and put as many as possible on one page in the PDF file before moving on to another page.

I am just spent half an hour hunting for a thing that should be totally available already:USB install images of Ubuntu, knoppix and all the others.And, the only good way are so far complicated tutorials where you extract the stuff from an CD image. Why??Hasn't everybody notices that CDs/DVDs are vanishing big time? That more and more systems don't have the readers anymore? Instead of following a 10 point instruction list, it would be nice to just be able to download a Ubuntu 8.10 or whatever USB image and be able to beam that DIRECTLY to a USB stick with a dd command.
Or am a missing something here? Does this exist?It should by no means be mariginal, considering how important USB stick in specific and flash memory in general have become.

i decided to install ubuntu in my PC,i downloaded the .ISO image and i installed it in my USB. After trying it and all that i observed that i really liked it and i decided to formally install it to my computer in the hard drive. When i reached the partition thing,i selected to dual boot with Vista and select between each them in every startup,when i clicked FORWARD it gave me an error which i did not read(because,again im a noob) so i clicked cancel.
Today i wanted to go through the process again and now really install it,so again i went to the time zone part and i clicked forward but then,instead of taking me straight to the partition phase,it appeard a window saying "The installer has detected that the following disks have mounted partitions: /dev/sda ...." I clicked yes,to unmount this partitions so it took me to the partition thing,once there i selected the option to install Ubuntu with Vista and select between them i neach startup,then i clicked forward and went to the username/computer name process,once i finished i continued to the next part,the installation,but i selected to import all of my WIndows VIsta default user data,after that i clicked forward and went to the installation process,i went down stairs to eat soemthing while it finishes,i came back and it was finished,it asked me to reboot so i clicked in Restart Now.
When it tried to boot,appeared an error saying: Error: no such devide found: #################### Grub load(or something like that) grub rescue: and it was a command line,since there i havent been able to boot into vista or Ubuntu,im really scared because is the first thing related to OS installing ive done,so i booted my USB and ran the trial and right now im trying to find out what to do from that trial version.
I just went to the INSTALL UBUNTU 10.04 LTS application under the System>Administration Menu and found out that in the partition phase the Install and allow to select between both systems in eahc startup option,i dont know what to do,i foudn out that my HD has still all its data(MUsic/Videos/Folders/Programs/ect.)its just that i cannot boot from it. Also in GParted it appears as /dev/sda1/ and a warning icon besides it,also when i go into information, thers this warning there [URL]

I've been searching the forums for any posts that cover my problem, but most of the booting problems I've found are different from mine.Anywho, the situation:ell laptop, 2 partitions, first is Windows XP, second is Ubuntu Karmic.Whenever I turn on my computer the first loading screen that shows up (is this the BIOS? Excuse my little knowledge of this stuff), before GRUB loads, is really slow. It takes about a minute to load.However, whenever I restart from my XP partition, it suddenly loads fast! And this does not happen when restarting from my Ubuntu partition or anything

I am using a linux kernel 2.6.36 using mips architecture. I have succesfully booted the machine through Flash memory, but it is not booting through nfs. It is getting stuck at the stage where the image starts loading. In short the vmlinux.img file is being copied properly to nfsroot but the image is not loading.

I am configuring an ubuntu system for a friend of mine, he is Arab and he used to watch (with windows) the films on this site: [url]
I tried to open the site with firefox but I cannot see the image on that page, I see the cursor changing shape and clicking with right button in the properties I see they are gif images, furthermore clicking on the (not displayed) images should open a link to the film but instead a blank page opens with error.

i have alot of images that need to be printed into a pdf.
i am not aware of any software that allows me to do this. and searching on the web is bringing to to alot of propitiatory garbage.
aside from openoffice, what alternatives do i have?
i do not prefer open office because it doesn't let me utilize the whole page smack-off-the-bat.
if it pasted images to the size they were meant to be (the whole page) it would be good enough for me (but its not ) the images need to be in a particular order.

I'm running Ubuntu 10.10 with an NVIDIA GeForce 6100 video adapter and my monitor seems to flicker whenever the the computer is processing. My system is up to date and I did install the recommended NVIDIA driver. The monitor isn't going blank or anything like that, it just seems like every once in a while different images will pop up for less than a second. Any ideas as to what the problem might be? I've attached a copy of the xorg.conf file as well:
Section "Screen"
Identifier "Default Screen"
DefaultDepth 24
EndSection
Section "Module"
Load "glx"
EndSection
[Code]...

I have a strange problem with sites on which there are many images, the likes of ebay or the google image search. The images or the preview images won't load in Ubuntu (I am on 9.10).
Neither using FF, Konqueror nor Chrome.... It can't be the router either, because when I boot into Windows on the same machine it is working.
It is even working on a MAC at the same it doesn't work on Ubuntu....

How to lower the resolution of all the images in a pdf? I searched around and couldn't find an answer to this. I have a pdf file of a textbook that I use in school but each page is an image of 2 pages of the textbook (left page, right page when the book is opened) and each image is of a very high resolution. I downloaded pdftk and pdfedit but for such a simple problem, I'm having trouble. Is there any way to do this?
I have tried converting the 380 MB PDF file to PostScript but after an hour of doing that, it stopped, and the PostScript only had about 17 pages instead of the 733. So converting it back to a PDF file to utilize pdftk's algorithms would have been worthless. I know I could split up the pdf file into sections but I'd rather just scale down all the images, or make them mid quality PNGs or high quality JPGs just so the filesize can be halved.

I've been playing around with arch and ubuntu in virtual box, and after many... many installs i realized it'd be practical to just image the virtual drive and do it that way.
Now of course I could just copy the vdi file, but that's cheating.
Kind of like what is normally done with norton ghost, however I don't have money to be buying it, and so it's left me curious about what utilities similar to ghost there are our there.

I am running Ubuntu 10.04, up to date, 32 bits. I tried to open a huge (10.000 x 1.200 pixels approx) Wikipedia image, and everything crashed. Nor Firefox, Gnome or anything else responded from there. Not even ctrl+alt+del, ctrl+alt+backspace, alt+F2, etc. Only the mouse moves, but rather slowly.
This is the image:

I could NOT replicate the problem with Chromium. However, I am not sure if the issue is only firefox since it locks up everything in ubuntu.

I'm using U10.04 and have installed all sorts of photo apps, but nobody can see the raw (*.RW2) files on my Panasonic DMC-FZ35. I borrowed a Win7 machine and Windows sees them. I put them on a stick and come back home and thenGimp with UFRaw sees them. How can I get U10.04 to see them right when I plug in the camera with USB?
