Ubuntu :: Creating A DOS Boot Disk From USB?
Jun 8, 2010
I have a Dell Vostro 1400 with the Nvidia GPU running ubuntu 10.04. There is a problem with the GPU and dell has recommended that you upgrade your BIOS. I have the executable that can run from either dos or windows. The problem is, I can't boot the system long enough before the screen goes blank on me, my option is to boot from a USB disk to a dos command prompt and then execute the update. I have the file, I just need instructions on how to create a bootable dos disk using a USB pendrive.

I have an 8gb USB Flash Drive. I am trying to make a Xubuntu 11.04 boot disk from it. I have done this once before with Ubuntu, but not Xubuntu. The problem is that when I go into the Startup Disk Creator, I get this error and the process stops. This is what the Flash drive file structure looks like after the process stops.

My laptop boot up time increased considerably (10 seconds) after allocating a virtual drive for virtualbox guest. The guest installation did not work so i removed it along with the virtual disk. Now everytime when i boot to ubuntu, after inputting my password in the login screen, it takes much longer to load the system. And during the loading time the disk activity indicator light blinks indicating the harddisk is actually busy loading the system.
I decided to search around for a possible answer and force reprofiling ureadahead does the trick Now boot time is back to what it used to be

I am installing Linux on some spare space I left over from my previous two Windows installations.
From within Linux, what's the most risk-free way of imaging these two partitions and saving them to a single image file or archive? I want to preserve the entire partition because I have no idea what I may have forgotten to copy. What is the most suitable program that can do this?
Is there any way to run the partition in a virtual machine at a later date?
After this is done, I want to delete those old partitions and extend my Linux ones.

I am trying to create a bootable USB drive. I go to System > Administration > Startup Disk Creator and click on 'Other' as the image I want to use is not listed. I then find the Chrome OS image and double click but then I return to the Disk Creator and it is still not listed as the source disk.
So does anybody know how to get around this so I can use this program to create a bootable USB drive, or another way that I can create one? I have used the Disk Creator to create a bootable version of Jolicloud (which is probably one of the worst Linux distros out there) before, but now it won't work.

I have the windows 7 install iso but no windows computers! startup disk creator only lets me use ubuntu variants. I have a mac and ubuntu 10.10, and i have so far found no way to write an ISO to a disk without paid windows applications like ultra ISO, its driving e ******* crazy, every time i want to write an ISO to a USB stick i need windows! and now i have a virus (trust windows)! Why can we only write .iso files to a disk in this world?
Can someone please point me in the direction of modern civilisation, were i can write an ISO to a pendrive for FREE with linux or macoh and i forgot to mention, im a sensible human being, so i dont have a disk drive - im not booting to the mac

I need (for a friend) to create a "driver" disc for a webcam that is uvcvideo compatible. The webcam when plugged into my machine works out-of-the-box using the uvcvideo module.However, for some reasons, we want to include a binary and/or sources file with it.
I have downloaded the source files from http://linuxtv.org/hg/~pinchartl/uvcvideo/ , but compiling fails. (build-essential is installed). I did not compile it using sudo since I do not want to mess up what is already installed on my system. Compilation according to the enclosed INSTALL file is as simple as "make" (no ./configure).
However, make give me errors
Code:
/home/user/downloads/uvcvideo/uvcvideo-553dfd853cba/v4l/et61x251_core.c: In function 'et61x251_ioctl_v4l2':

this is in the wrong section, but I wasn't sure where to put it. Since the background to my problem is kind of long winded I've split this post into two sections: Short version of problem
I have a PC that has two internal drives: one drive (drive A) is empty, and the other (drive B) has a copy of windows vista installed. At the moment the PC boots from drive A. I'd like to transfer everything from drive A to drive B, so that this new disk will boot and behave nicely and windows will still function.
Is there any easy way to do this in ubuntu? I'm guessing I can use something like dd, but will this copy the boot sector and will I have to mess around with the partition table? Long version of the problem
Today I built a new PC for my dad with two internal drives. He was previously using vista on a laptop which died a few days ago, and I'd like to install vista on one disk of the new PC, and ubuntu on the other disk.
He has a licensed copy of Vista for his laptop, but it came as a "system restore" disk, and so I can't install vista directly onto the new PC. I have an identical laptop to his, so I took out the drive from his laptop, put it in my laptop, and did a "system restore" from the disk that came with the laptop. I then took out the drive from my laptop, and put this inside the new PC. It boots up fine, and I installed all the necessary drivers and etc to make windows work.
Now instead of using a slow/small laptop drive inside the new PC, I'd like to be able to clone the data on laptop disk and this onto one of the bigger/faster internal drives of the new PC. How can I do this from ubuntu, so that the new drive will boot windows?
I'm fairly certain it can be done using dd, but how do I make sure the information in the boot sector (or partition table) is correct for the new drive? I'm asking this because when I put my laptop drive into the new PC initially, I had connected it as an external drive, and when I tried booting from this there was an error, something like "Invalid partition table" (I think). I figured that when I did a "system restore" on my laptop, the drive was the only drive available, so this would be HDA, or SDA in the boot record of that disk. But when I added it to a system where other drives were available, it was no longer at that same location, so the boot loader couldn't find the data it was looking for to load the system.

how to get a working bootable USB boot disk for DOS using Fedora 12. I needed the dos boot disk to flash my motherboard BIOS as it did not support linux for updating the bios. Thought I'd put the steps involved to help other people who wanted to do something similar. The steps outlined here are for a Fedora 12 system. You should be able to extrapolate the minor changes that may be required for other linux distributions. All commands listed below to be typed in on a command prompt, logged in as root. Here goes...
1. Prerequisites:
syslinux
testdisk

Acknowledgments:

Could anyone recommend a method of creating a full disk image. I have the Acronis bootable media, would this work to backup Linux partitions? I'm thinking that Acronis doesn't know or care what is written to the disk as it works at a lower level.

I am new to the Linux world and I am not sure if what I am trying to do is achievable or not. I am trying to make an image of my existing drives running Linux on a USB and I want to use the same image off the USB to clone more bootable hard drives. Something like what Ghost does in windows. The problem is using 'dd' the image is too big ( I have 1tb drives ) and then I am not sure how to convert these images back on to new drives so that they boot in the OS as well. i am not sure if there is a utility that would let you do that?

I'm quite new to linux, but I've managed to grasp some basics. Now my intention here to create a virtual directory, which I resorted to creating an Image File so that I can mount it and have my folder have a dedicated storage. I will mount this image as a loop device. Well it's not much of a problem, but I would like to know whether this is suitable. Say I want to create a 25GB Image.
Code:
dd if=/dev/zero of=/home/disk-img/25GB.ext3 bs=1G count=25
Is this recommended? I'm using block size as 1G which is really huge, so I was wondering, if this is actually recommended. From what I read, some said that it's only advisable to use 4096k or lower, but what I found was that these suggestions are very dated (year 2003), and it is now 2010, so I would like to know if it makes any big differences.

I have read similar threads, googled, and an idea of what might be required. Hopefully someone here has actual experience and can detail their methodology. My setup is: Two boxes running Slackware 13.1 (not 64) with current patches. One has a Hauppauge pvr 350 card. The other has a Hauppauge hd-1600 card. I have old VHS tapes of pre-school graduations for kids now in their thirties. Since this project has no DRM issues lets say all my video programs use standard Slackware build scripts. I am comfortable modifying and running Slackware build scripts. The collection of video programs includes ffmpeg, HandBrake, VLC, Kaffeine and avidemux2. Currently on the box with the 350 card, I use the S-video in & line in to capture the output of a super VHS player. Because this is a slowish box I was having sync issues and finally wrote a script that
[Code]...
still have to know when to hit the enter key so an old tv is also hooked to the VHS player. So now I have an in-sync file nearing 6G which gets transferred the next morning [read that is the reason it's done on the slower box] to the faster box. As others in the household have a number of apple products the final file extension will probably be .m4v. I am slowing moving away from that as it is easier to stick a laptop running VLC with hdmi out on the tv then it is to go thru apple's home sharing. Another story entirely so lets not argue that topic merely say .m4v is not cast in stone. Depending on the time length of the tape, I would like to create 10 to 15 chapters in the final product. So there you have it. What steps to you use to create a final file with chapters. ps Yes the script should really check that $1 is numeric however I am/was the only user.

We have some servers that run in very harsh environments (research vessel) that need to have high-availability.We have software RAID 1 for some measure of resiliency, along with proper data backups (tapes etc), however we would like to be able to break out a new server and re-image it (including RAID setup) from a known good copy if the hardware completely fails on the production box. Simplicity of the process is a big plus.I am interested in any advice on the best way to approach this. My current approach (relatively new to Linux administration, totally new to MDADM) is to use DD to take a complete gzipped copy of one of the RAID'ed devices (from a live CD): ode:
dd if=/dev/sda bs=4096 | gzip -c > /mnt/external/image/test.img then reverse the process on the new PC, finally using Code:mdadm --assemble to re-create and re-build the array.

I have a (slightly complicated) dual/multi boot system.
I keep getting boot errors (when choosing ubuntu from the grub2 menu)
Code:
Serious errors were found while checking the disk drive for /boot
If I switch off and restart, ubuntu will then start without issue.
My setup is like this ....3 disks, one with 10.10 clean install - so Grub2, separate partitions for /, /boot and /home, one with windows 7, one with windows XP and 10.04 wubi (this is my old disk which I will trash once I'm happy with my upgrade to 10.10 & 7 on separate disks.
I installed 7 and 10.10 with ONLY their disks installed. After both were working, I added all disks and rejigged the grub2 menu (using update-grub and StartUp-Manager).
This problem only seems to occur if my previous boot was not 10.10 ( I will investigate this further). It's as if something (grub2 ?, the bios ?) is remembering part of the previous boot and not using the grub2 menu completely.

my Fedora 11 system is not starting anylonger. It stops with the message:
Code:
VFS: Can't find ext4 filesystem on dev dm-0
The system told me since a while, that a lot of the sectors of one disk of the (software) RAID compound are failed already. So tried to disconnect each of the disks and start them separately. Unfortunaltly this is not working (for one its is not working at all, the other wents the same far as with both), when I tried to recover the system with the Fedora DVD, it said no distribution found. I am quite new and do not know so much about linux system, so i do not know what further information you could need. Maybe it can be important, that both disks are encryped (the system wents so far, that I can type in the password).

I installed Debian on my PC with a Acer Stock motherboard (xc600) with amd64 and after the installation finished it told me to remove my installation media and reboot. After reboot I was returned this message ' ERROR: No boot disk has been detected or the disk has failed.'. I have verified with gparted using mint live OS that I have Debian installed on my system.
I got believes that this may have be caused by a broken grub or I need to configure something I don't know how in BIOS.
I will update the topic later..
My installation media was a USB 2.0 flashdrive with a Debian 8.2 Jessie Installer and 9 different Linux distros. I have installed Debian multiple times before on my laptop and never had this problem so I know how to go through the installation process and set the partitions.

I've spent the past several hours trying to determine how I can mount a Windows 7 ISO onto my USB drive using Ubuntu. I have followed this post, as it is the only thing that came up on Google after hours of searching (mostly it shows how to make a Ubuntu USB drive on Windows, not vice versa.)
Using the method in that post, it seems like I was successful. However, after a few seconds it gave me an error like this.
Code:
Load Driver
A required CD/DVD drive device driver is missing. If you have a floppy disk, CD, DVD, or USB flash drive, please insert it now.
Note: If the Windows installation media is in the CD/DVD dive, you can safely remove it for this step.
