Install Ubuntu into RAMDISK off HD?
location: ubuntuforums.com - date: July 23, 2009
Goal: Build a laptop that can be given to clients for temporary use, while they visit our facility. It would be able to connect to our public wireless and would really only need to be able to surf the internet. I would really like to be able to load into RAM everytime, that way once it is turned off/restarted, we are starting with a fresh desktop.
I would really like to be able to load the distro right off the HD into a RAMDISK. I wouldn't want them to be able to mount any drives or get to any terminal windows. Basically, purely a internet machine. (Maybe a calculator, paintprogram, notepad, etc...)
From what I have been looking at, Puppy Linux is pretty much designed for this. My only problem with it is, I feel like it is to bloated and that I would have to do a lof of modifications to it, (Remove all the fat, would rather use FireFox, etc...). If I have to go that root (pun intended) I will, but most of my linux work up to this point has been on Ubuntu and I feel more comfortable
HD clonning with dd
location: ubuntuforums.com - date: October 22, 2008
Ok this is my setup
2 HDs with lots of space.
HD 1 have Ubuntu and XP. NTFS partitions, ext3, etc.
HD 2 is used for data for XP and Ubuntu
I want to store my HD image to a file. But, I don't want to have in my image the same free space that exits in my HD.
I know i can resize them before clonning them.
What happens if I resize them then clone. What will happen whenI restore the image. I guess the other space will be unpartitioned?
Is there any other way to leave out all that free space in my HD.

that will launch the installation
4. an available partition for installing the new system
How to Mount/Use HD in Linux Mint & Windows 7 Dual boot
location: ubuntuforums.com - date: July 9, 2013
I recently installed Linux Mint alongside Windows 7 (with Windows 7 being the primary OS), and Linux Mint won't mount the Hard Disk from the Windows 7 OS. I can use the partition (or whatever it does when you use the Windows Installer version for Mint 15) for the Linux side of it just fine.
Any idea of what to do? Thanks for the tips!
how do you give more hd space for linux on android phones?
location: linuxquestions.com - date: May 2, 2012
I just recently installed ubuntu linux onto my android bionic phone and I must say I loved it!
I was having so much fun with it, but at the same time I was having too much fun. I started installing too many apps that were taking up more space and when i went to install another app i believe it was openjdk (java) "apt-get" gave me an error saying "dkpg" was out of space and i needed to do "dpkg --configure -a" to fix the problem...
then when i did "du -sh" it came back with "213MB".
After that problem happened when i tried to load ubuntu back up on my phone and run androidvnc to connect to the lxde desktop window manager (gui) it would say that androidvnc was connected to "localhost" but only show me a grey screen with an "x" that was acting like a mouse.
So now i am forced to format my sdcard and download and reinstall ubuntu linux all over again... (this is just part of the whole linu
LXer: Intel Iris Pro 5200 vs. HD Graphics 4600
location: linuxquestions.com - date: September 22, 2013
Published at LXer:
After several weeks of testing the Linux-friendly System76 Gazelle Pro Haswell laptop, we've now been using the System76 Galago UltraPro for a wide variety of Linux testing as its powered by the Core i7 4750HQ CPU with Iris Pro 5200 graphics. In the preview article for this System76 ultrabook we ran some early comparative tests while in this article are some direct Ubuntu 13.10 comparison benchmarks between System76's two Intel Haswell laptops. What's most interesting to see with these results is how much faster the Iris Pro graphics are over HD Graphics 4600.
How to create ISO images from your HD CD DVD
location: ubuntuforums.com - date: November 29, 2004
This is very helpfull to backup you cd and dvd into iso images:
To make an ISO from your CD/DVD, place the media in your drive but do not mount it. If it automounts, unmount it. (ubuntu automount so you need to unmount, that's quite easy, just choose the option unmount from the shell).
dd if=/dev/dvd of=dvd.iso # for dvd
dd if=/dev/cdrom of=cd.iso # for cdrom
dd if=/dev/scd0 of=cd.iso # if cdrom is scsi
To make an ISO from files on your hard drive, create a directory which holds the files you want. Then use the mkisofs command.
mkisofs -o /tmp/cd.iso /tmp/directory/
This results in a file called cd.iso in folder /tmp which contains all the files and directories in /tmp/directory/.
For more info, see the man pages for mkisofs, losetup, and dd, or see the CD-Writing-HOWTO at http://www.tldp.org.
Hope it helps
How long DD on a 1TB HD takes?
location: ubuntuforums.com - date: April 26, 2013
I bought a 1TB drive and I'm planning on doing DD on it. It's a WD, so I guess using a Seagate disk to wipe is not recommended.
What does it take? (what commands), How long? Does doing it very often hurts the drive? (my old 320GB drive had +4000 reallocated sectors)
All I'm used to do is:
* Erase the partition table with $sudo dd if=/dev/urandom of=/dev/sda count=1
* Create random size partitions with random file systems
* Delete all partitions
* Erase the partition table again and then create the partitions I needed.
Are those above enough, let's say, in a virus case, a bootloader virus or a MBR virus? WHY and in what cases are DD needed besides selling the drive? How is data recoverable? Can the FBI recover it?
Currently my partitions are:
- 320GB for Windows, used ONLY for games, nothing pirated
- 40GB for /
- 571GB for /home, encrypted.
Thanks in advance.
Could Linux have made my USB Hd unreadable by windows?
location: ubuntuforums.com - date: July 7, 2010
I'm pretty new to using windows,but for reasons of comaptibility, a few games for the family etc, I'm now running a dual boot Windows 7/Ubuntu 10.04 machine, but ubuntu is still my basic OS. I have an external USB drive ( a fujistu 250Gb thing) which I used with linux, using an ext3 filesytem. I've tried using linux to delete all partitions, and also to format it to FAT and NTFS, but windows won't recognise it whatever I do. I just get an error saying that my USB device has malfunctioned.
Any ideas what I can do to get Windows to see it again? It works fine in linux. It couldn't be that Linux has somehow rendered it unreadable could it? I'm posting the smae thing on a windows 7 forum. It would be annoying if each camp blamed the other!!!
