Install Ubuntu from ISO image directly from hard disk of a system running Linux? [duplicate]

1

Add the Grub2 entry:

The entry for the ISO image needs to be added to /etc/grub.d/40_custom file. Edit the file by:

gksudo gedit /etc/grub.d/40_custom

And replace the text in that file with this one:

#!/bin/sh echo "Adding 40_custom." >&2 exec tail -n +4 $0 # This file provides an easy way to add custom menu entries. Simply type the # menu entries you want to add after this comment. Be careful not to change # the 'exec tail' line above. menuentry "Kubuntu ISO" { set isofile="/boot/iso/kubuntu-12.04.iso" loopback loop (hd0,8)$isofile linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile noprompt noeject initrd (loop)/casper/initrd.lz }

Where is:

Kubuntu ISO = The name you want to display in the Grub menu. boot/iso/kubuntu-12.04.iso = The location and name of your ISO image. (hd0,8) = The partition which contains the ISO image. note: the tail -n +4 means simply "which line grub starts to read the configuration from as is". the...

Hi all, today we'll teach you an awesome interesting stuff related with the Operating System Disk Image and Booting. Now, try many OS you like without installing them in your Physical Hard Drive and without burning DVDs or USBs.

We can boot Linux ISO files directly from your hard drive with Linux’s GRUB2 boot loader. We can boot any Linux Distribution's using this method without creating bootable USBs, Burn DVDs, etc but the changes made will be temporary.

1. Get the ISO of the Linux Distributions:

Here, we're gonna create Menu of Ubuntu 14.04 LTS "Trusty" and Linux Mint 17.1 LTS "Rebecca" so, we downloaded them from their official site:

Ubuntu from : http://ubuntu.com/ And Linux Mint from: http://linuxmint.com/

You can download ISO files of required linux distributions from their respective websites. If you have mirror of the iso files hosted near your area or country, it is recommended if you have no sufficient internet download...

How can I rip an audio CD to an ISO image?

It seems I have found directions for using brasero to rip a CD to .iso file, but according to that, brasero is three(3) kinds of broken.

recording image as cdrdao does not work, even after reinstalling both brasero and cdrdao. Brasero closes (crashes?) with assertion error. same with trying to rip to a .cue file. There is no option for ripping to a .iso file.

What gives? I mean, what should I do? I really want .cue and .iso files, but I don't know what to think about cdrdao. Thanks.

Update: This is an audio CD. Do those make good .iso files?

Ubuntu is one of the most popular Linux Distribution.According DistroWatch.com Ubuntu and Linux Mint are the two most popular linux distros.Linux Mint is a derivative of Ubuntu.It is a customized version of Ubuntu.

Since new versions of Ubuntu and Linux Mint are released every 6 months, there is no point in burning the iso files to blank cds.

So how does one install Ubuntu or Linux Mint without burning the iso files?

Two possible answers to the above question.

I have previous versions of Ubuntu, which includes grub2. I see on the Internet that, grub2 can boot from iso file, So, I booted Ubuntu from iso file, But whenever I tried to install, it gives an error that, "The disk need to be unmounted first before install".

My question is: How can I install Ubuntu 12.04 from iso file using grub2?

Answers

I have successfully booted from iso file and install from that iso file!

The procedure is here

In 2nd command, if vmlinuz doesn't work use vmlinuz.efi .

After typing boot press Enter. The Live Ubuntu system will be started.

Notes:

If you put your iso file in a partition other than 2nd partition, change (hd0,2) to (hd0,X), where X refers to the partition number. If you put your iso file in a USB pendrive, and you start grub2 from Hard disk (installed by your previous system) , change (hd0,2) accordingly. If you have only one partition in the pendrive, it will be (hd1,1)....

This question already has an answer here:

Using a bootable live cd disk image mounted on the hard drive 2 answers

I found this looking around on the net.

Grub2 is capable of directly booting ISO images for many Linux distros if the entries have been properly defined in the Grub2 configuration files.

The ISO image must be placed on a separate partition that does not have an operating system installed on it. For the sake of simplicity, we would place it inside a new directory under /boot (assuming it is on a separate partition).

Create the new directory and copy your ISO image:

sudo mkdir /boot/iso sudo cp ~/Desktop/name.iso /boot/iso

Where ~/Desktop/name.iso is the location and name of your ISO image assuming that the image is located at your desktop.

Add the Grub2 entry:

The entry for the ISO image needs to be added to /etc/grub.d/40_custom file. Edit the file by:

If you already have Ubuntu installed, it is easy to upgrade using the Update Manager. However, this is not always safe, and it will overwrite your old system.

If upgrading is not an option (you are running a different Linux distro than Ubuntu, or your system is several versions old), or you wish to keep your old system, you should use the live Ubuntu Desktop installer or Debootstrap.

The Ubuntu Desktop installer is usually run on a DVD or a bootable USB stick. However, if you already run Linux, using a DVD or USB is not necessary. You may run the Ubuntu Desktop installer directly from your hard drive, or use Debootstrap.

Note: These are advanced installation techniques and are not recommended for new users. If you are uncomfortable with the command line terminal, you should create a live Ubuntu Desktop DVD or USB.

Running the Ubuntu Desktop installer from your hard drive requires an extra partition. Debootstrap installs Ubuntu directly, without using...

After you download any Linux distro from the internet, you have to burn it to a DVD, CD or a number of CDs to install it. That CD or DVD is generally used only once after which it lies unused , and worse, almost every Linux distro comes up with a new release every 6 months. So if you are in the habit of upgrading to every new version, you must have dozens of CDs lying at the bottom of your drawer. What a wastage of CDs! But with a little trick you can install any Linux directly from the hard disk without burning a single CD or DVD. The prerequisite of this trick is to have an operating system already installed on your computer. This is obvious because unless you are able to boot into your machine, you can't install anything; and we are not going to boot from the Linux disk because we aren't burning any. Here I'm going to focus on Microsoft Windows as the pre installed operating system.

Almost all Linux installers uses two files to boot the computer: a Linux kernel,...

Not too many years ago if you wanted to try out the latest Linux distro, test to see if a repair CD you downloaded worked or whether your custom made Windows install disc could boot, you had to burn the content to CD or DVD and then reboot your computer to try it out. This not only took vast amounts of time waiting for the disc to burn but it also meant perhaps fiddling with the boot order in the BIOS and if you didn’t have any rewritable media, every burn would cost you money.

These days disc images (ISOs) are everywhere and that allows you to do several things such as burn to CD like before, mount the ISO as a virtual drive, install the image onto USB flash drive, or even load it into virtualization software to test without leaving your desktop. The trouble is using the above methods to boot the ISO image can still take time which isn’t ideal if for example you quickly want to try a number of the latest Linux distros. Being able to boot and test an ISO image with just a...

One of the first problems encountered by users these days is that they run out of disk space to store data. Fortunately disk space is now one of the cheapest of all IT commodities. In this chapter we will look at the steps necessary to integrate a new disk drive into an Ubuntu system.



Getting Started

This tutorial assumes that the new physical hard drive has been installed on the system and is visible to the operating system. The best way to do this is to enter the system BIOS setup during the boot process and ensure that the BIOS sees the disk drive. Sometimes the BIOS will provide a menu option to scan for new drives. If the BIOS does not see the disk drive double check the connectors and jumper settings (if any) on the drive.

Finding the New Hard Drive in Ubuntu

Assuming the drive is visible to the BIOS it should automatically be detected by the operating system. Typically, the disk drives in a system are assigned device names...

Using linux with Windows 8 could be different from older Windows versions, things like EFI/UEFI and Secure Boot need some special attention. See this question on Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported).

It should be possible to install GRUB (GNU bootloader)onto your hard drive, and have it load the Ubuntu ISO directly from the hard drive too. I haven't installed GRUB from Windows myself, but according to a google search for "install grub from windows" it looks possible. And here are some links & very brief directions about a Multiboot USB:

But, easiest answer would be borrowing a USB drive (preferably one with a Ubuntu iso already installed), or borrowing a dvd drive & a Ubuntu DVD would be best. Being a college student, I'd imagine there are lots of other students who have them, maybe even a computer club or linux club that could help you, or even install it with/for you, especially if it's a laptop?

Install Linux Without Burning An ISO To CD/DVD - Use The ISO Downloaded To Your Hard Drive

I have written this complete article on my blog also: http://mightydreams.blogspot.com/2007/09/i-am-describing-here-method-to-install.html. I am describing here a method to install Linux without using a DVD ROM or CD Drive; I have checked it myself. There are many ways to do so you can install Linux by 1) booting from the network; 2) having an ISO image on your hard disk; 3) booting from USB; 4) installing a linux system from scratch by building your own.

I am assuming that Linux is not installed on your system and neither grub or lilo is there. This method is using an OpenSuse 10.2 Image but is same for Fedora or Debian or any other distro. There is one check point in case you used Nero to copy CD or DVD image then it might have been possible that you copied the image and it is file with dot nrg extension in that case you need to get the ISO from NRG.

GNU/Linux comes in many different flavours, apart from the fact that each individual distro has a new release almost every six months, if not less. I have a habit of trying out every new version the moment it comes out, and I’m sure many of you do too.

Now, let’s assume you have downloaded a new version of a distro and are in the mood to try it out right away. It’s past midnight and you realise that you’ve run out of blank CDs/DVDs. So you will have to wait till the morning when the shops open, to be able to burn the distro image in order to install it. I’m sure a lot of us often face this problem. In this article I’ll share a simple trick by which you can install the new distro without burning it to a CD/DVD. The only requirement is that you should have a pre-installed GNU/Linux system—which you already have, I assume.

The title says it all! More specifically, I am running Fedora18 on my main HDD. I have a second HDD in the "UltraBay" slot of my ThinkPad W520--eSata connection.

Is there a possibility to avoid creating a LiveCD/USB, etc, and, perhaps, to directly write the extracted ISO contents of a different distro (Ubuntu) to the second drive; or to use a virtual system as a means of facilitating a "non-live/non-virtual"/REAL installation of an OS?

There's got to be a better solution than having to deal with the annoying media-creation! I'm not too familiar with PXE booting, but it seems that even that adds an extra step of preparing the network server/system for allowing access, etc.

Thanks for any and all comments and answers.

Disk Image is a computer file containing the complete contents and structure of a data storage device. The term has been generalized to cover any such file, whether taken from an actual physical storage device or not. See more...

A common use of disk images is for remote distribution of software such as Linux distributions: installation floppy disks or CD-ROMs can be recorded as disk image files, transferred over the Internet, and the contents of the original disk(s) duplicated exactly by end users with their own floppy or CD-R drives. So, user can burn the images to convert them in LiveCD s, to try an Operating System, without installing it in the hard disk .

Another common use is to provide virtual disk drive space to be used by SystemVirtualization. This can prevent the CD from getting burned or damaged. It can also reduce bulk when one wishes to carry the contents of the CD along with oneself: one can store disk images to a relatively lightweight and bootable...

When building a Linux installation, there are two options. The first option is to find a super-fast solid state drive. This will ensure very fast boot times and overall speed when accessing data. The second option is to go for a slower but beefier spinning disk hard drive – one with fast RPMs and a large amount of storage. This ensures a massive amount of storage for applications and data.

However, as some Linux users are aware, solid state drives are nice, but expensive, and spinning disk drives have a lot of storage but tend to be slow. What if I told you that it was possible to have both? A super-fast, modern solid state drive powering the core of your Linux and a large spinning disk drive for all the data.

In this article we’ll go over how to install Ubuntu Linux with separate root and home hard drives – with root folder in the SSD and home folder in the spinning disk hard drive.

This guide will shown you two method how to boot an ISO image file that stored in your hard drive. Booting an ISO on your hard drive is useful for testing new versions of Linux ISO file without using up a CD/DVD or USB Stick.On this case I will boot Ubuntu 13.04 iso directly from hard disk via the Grub2 boot menu.

There are two methods to boot Ubuntu ISO image from hard drive. Two methods are provided below, Method 1: using the grml-rescueboot to automatically create the GRUB menuentry and Method 2: Manually editing the GRUB 2 configuration files.

Method 1 : Boot ISO Image using grml-rescueboot

grml-rescueboot is a package provides a script for update-grub which looks for Grml ISO images in /boot/grml and automatically adds an entry for each image. The purpose is to use one of those images to boot a Grml rescue system without using a CD/DVD or USB stick.

Most Linux distributions will be able to boot from a USB live environment, so that users can test the system without having to install. We can use it to review the release or simply as a one-time system, and it is easy to copy these files to a U disk, in some cases, we may need to frequently run the same or different ISO images. GRUB 2 can be configured to run directly from the Start menu, a live environment without the need to burn the ISO to a hard drive or USB device.

Obtain and inspect bootable ISO image

In order to get the ISO image, we usually should visit our download architecture-compatible image files required for this release of the site. If the image can boot from the U disk, then it should be able to boot from the GRUB menu.

When the image download is complete, we should check it with MD5 checksum integrity. This will output the sequence of a long list of numbers and letters synthetic.

This sequence will be provided with the download page MD5...

Grub2 is capable of directly booting ISO images for many Linux distros if the entries have been properly defined in the Grub2 configuration files.

What if you don't have access to a CD/DVD drive/disc or a USB drive and you want to install Ubuntu (or any other Linux)?

Or if you want to perform some system maintenance tasks like those related to partitions or filesystems which can only be performed from within a Live CD environment?

Grub2 comes in handy at that point as it would not only boot the ISO image from your HDD, but it would also let you perform an installation from the ISO image if you want to.

Things You Need

An existing install of Ubuntu (or any other Linux) with a working instance of Grub2. The desired ISO image that you want to boot/install. Procedure

The ISO image can be placed virtually anywhere on your HDD but for the sake of simplicity, we would place it inside a new directory under /boot.

If you want to experiment with Linux without dual booting and potentially impacting your main operating system, the best way to do so is with virtualization. Virtualization allows you to run Linux directly atop your primary OS, whether it’s Mac OS X or Windows, in a separate virtual machine, with practically no potential for error. It’s completely free and fairly easy to set up, we’ll walk you through the entire process.

Requirements for Running Ubuntu in VirtualBox

Be sure to meet the above requirements before beginning. Once VirtualBox is installed and the Ubuntu ISO is downloaded, you can proceed with set up and installation.

Installing Ubuntu Linux in VirtualBox

Launch VirtualBox and create a new virtual machine, name it something like “Ubuntu Linux” and set the Operating System to “Linux” and version to “Ubuntu” and set the base memory to at least 512MB or 1GB
