Debian :: Boot From Live DVD Into RAM Memory
Dec 30, 2015
When Debian OS is booted in to memory, this is a clean boot, because with the iso on the DVD can not be tampered with, but someone who has hacked your modem, can target your IP and can place a keylogger in the RAM memory, side-by-side of the OS, does not necessarily need to know zero-day-exploits of Debian (if there are any). Is that correct?
Moreover the trick, once known and automated, can be repeated every time you boot from the Debian Live DVD?

Ok so I wanted to try out Debian, so I got the wheezy live image (gnome) via torrent. The problem is after I write the image to the USB, the computer cannot boot from it. It doesn't even display the USB in the boot menu. I've tried many ways of writing the image like dd, powerISO, UUI, imagewrite (not sure if that was the correct name) etc. Strangely enough, it works on a virtual machine via Plop Boot Manager, but not my actual PC.

On a new Lenovo Thinkpad T450s, I encounter the following issue: The USB drive containing live CD image ("burned" to the USB using mkusb tool --> which in turn uses dd) cannot be booted from the UEFI boot loader. I have to reconfigure the hardware (BIOS) setup to support both UEFI & legacy system, and with first boot priority given to legacy (BIOS-style) booting. But if I do this, I don't see the UEFI system in the /sys/firmware/uefi directory. I am using the 64-bit live CD image (debian-live-8.0.0-amd64-xfce-desktop.iso).
This is my goal: to boot the live USB from UEFI, so that I can install it in a form that is UEFI-bootable.

I'm trying to boot Live Debian (on a usb stick) on a Dell XPS ('Developers Edition' aka 9343). From what I've read about the status of on this hardware [URL] and about Debian Live (https://www.debian.org/CD/live/) it sounds like this may be possible, but I haven't figured it out. I don't know how to deal with the bios &| uefi settings.
I created the boot stick with dd if=debian-live-8.3.0-amd64-mate-desktop+nonfree.iso of=/dev/sdd1 bs=4M; sync

I am attempting to get Debian+Mate running on my laptop, with no success. I have not yet used Linux, but I do wish to climb out of the Window, and the Live session seems ideal to get a feel for Debian before finally abandoning Windows.
I got the Debian+Mate ISO file from the Debian website, and created a bootable USB stick. (Note : I have done this several times, getting new ISOs, and using Unetbootin, Universal USB Installer, and Linux Live installer; the result is always the same.)
When I boot the USB drive, all appears good at first. I get to the Debian (or Mate?) screen which is a pale jade green with a white squiggle in the middle region, with a panel at the top; this shows at left three options - applications, places, and system; and at right the correct time, a sound symbol,the wifi symbol, and a battery indicator. At the left of the screen in vertical arrangement there are 4 icons labelled computer, users home, install Debian Sid, and trash. On the bottom panel, at left there is a "button" for "click to hide all windows & show desktop", and at right 4 squares for workspaces.
There are also (temporary) windows that inform me that the battery is no good (I run on mains), and that there is no wifi connection established. These windows disappear in a minute or so.
The cursor moves ok. The only actions that it creates are the information drop-down texts that tell me what the headings mean - e.g. no connections when I hover the cursor above the wifi connections symbol.
But whatever I attempt to do - selecting any of the options - nothing happens. Everything except the cursor appears to be dead.
The machine that I am using is an old laptop that I use as a second computer. It has a SIS Mirage 3 graphics engine, which I gather may be a problem. I also tried the same procedure with my fairly modern ASUS laptop (NVidia graphics) with exactly the same results; it seems that NVidia graphics may also be problematic, judging from some posts on the web. I have also tried Debian+Cinnamon, again with the same outcome.

As you probably know Debian LIVE ISOs is not (U)EFI bootable since there is no EFI bootloader on them. I need to boot usb for uefi mode...

I've created my own wheezy live usb-hdd using:# lb config -a i386 --mode debian --distribution wheezy --linux-flavours 686 -b usb-hdd --bootloader syslinux --memtest none -p xfce
P: Considering defaults defined in /etc/live/build.conf
P: Creating config tree
# lb build
The binary.img was created.
Now if I try to boot from this image using qemu, I get a message "No bootable device"
If I check this main partition using gparted, the flag is "lba" instead of "boot".
Even doesn't work if try to change to "boot".
How to solve this problem?

I just set up my USB drive with debian wheezy and the first time I boot with it, I was able to choose install options but I shut down my computer and now when I attempt to boot with my USB the screen is black (after esc F9 and choosing the USB) so I tried dd debian.iso a few more times but I am convinced that my USB needs to get completely wiped so that I can put the debian.iso back on and try again.
Any terminal command that can wipe USB drive?

I'm new on this forum, but not new on linux and in general on Ubuntu and Debian and I've always programmed on these OS but I still have a long way, however, in fact I have a new Aspire E15 573G in which there is the UEFI that creates many problem on the boot of different systems but I need to change Windows 10 to Debian or to have both them because I hated Windows.
I searched in many sites to find because my debian live charged on my usb pen doesn't boot in any manner, I read that the live debian still does not start on UEFI systems but I still BELIEVE that there is a method to boot it up and I found this: [URL].....
So my request to you for now is what are the boot parameters to set to the liveboot.nsh? because that configuration doesn't solve the problem, Debian wanted ACPI disabled so I modified the .nsh but still there's the black screen.

I am very much new to Debian. To have a feel and check if my laptop (HP Elitebook 6930p) is supported I decided to use a live USB option. I know how to create a live USB disk using Ubuntu and using the same knowledge I created the USB disk and tried to boot using it. The system starts to boots off the USB drive and then is stuck at a point where it fails to identify my HDD. Here is what I did
a) downloaded the debian-live-508-i386-gnome-desktop.iso/debian-live-508-i386-gnome-desktop.img/debian-live-507-i386.iso (I tried with all 3)
b) created a live USB using unetbootin
c) tried to boot from live environment
My laptop's hard drive is encrypted using SafeBoot.
After all the 3 debian images failed to boot I tried with other Linux flavors such as Mint and Ubuntu. Interestingly Mint and Ubuntu boot. Is there some thing I need to take care of?

Today, I burned a copy of Lubuntu 10.10 Maverick Meerkat and tried installing it on my old 2.4Ghz Celeron 192MB RAM (actually 256MB with 64MB dedicated by the BIOS for the internal video card) laptop, which installed Lubuntu 10.04 Lucid Lynx with absolutely no problems. However, when I tried inserting the disk for Maverick this time around, the live CD boot always hangs during Plymouth, and pressing Esc shows:
Code:
Generating locales. en_US.UTF-8.I modified the boot options and removed splash and quiet, and I got a whole lot of messages that seemed like errors, but I think the root of the problem was this:
Code:
Out of memory: kill process 620 (localedef) source 929 or a child Killed process 620 (localedef) VS2: 59500kB, anon-rss: 57596kB, file-rss: 820kB After that, it got a few messages about localedef timing out for 120 seconds or something. Now I'm no idiot, I'm well aware that my laptop is cutting it very close to the minimum RAM requirements of the live CD, but it's just the live CD that stops me from running Lubuntu, because once it's installed, I have no problems. I ran Lubuntu 10.04's Live CD with no problems and the installed LXDE system ran amazingly fast. I'm sure if I could just install Lubuntu 10.10, it would run at the same speed. The problem is that the Lubuntu wiki still writes the minimum system requirements of:

I have been frustrated attempting to get Grub2 to boot a Debian Live system from hard disk. Have set aside a 4gb partition /dev/sda1 to contain the Debian Live and some other recovery tools. I actually have them all working from a 4gb USB stick successfully, but getting it to work on my HDD has proved challenging. On USB, I have PartedMagic, Gparted, Grml, and of course my standard 6.01 Squeeze. I have also managed to get the Debian Live booting from that USB stick. Very slick.
However, I can NOT get Debian Live to boot from my HDD; altho all of the others above boot fine. Have tried it two ways - one using an iSO image, which is how it is done on my USB stick. The other attempt is to copy the entire contents of the ISO to a directory.
Here are my directory structures:
debian_live_gnome_squeeze_i386- contains the following: debian-live-6.0.1-i386-gnome-desktop.iso initrd.gz initrd.img vmlinuz which is how it is laid out on my USB stick debian_live - contains the files from the ISO image The error I get is something like "panic unable to find live filesystem" My grub.cfg snippet for the two methods I have tried - the 2nd menuentry is similar to how it works on the USB stick.
menuentry "Debian 6.01 Live (on /dev/sda1)" {
insmod part_msdos
insmod ext2
set root=(hd0,msdos1)
[code]....
Probly don't really need to get it working since PartedMagic can do almost everything I need for recovery and I can use the USB for reinstall or whatever else.

My system has been running really sluggishly for a while and I've finally identified the problem. I'm using all my memory which is causing swapping to occur.When I started trying to fix this problem though, I began to notice some strange things. For example, I wanted to figure out what processes were taking up all my memory, and the answer I found was that none of them are. While every tool I use to see how much memory I'm using (sysinfo, top, etc.) reports that I'm pretty much using all 2 GiB plus some swap space, all the process lists that I look at (top, system monitor) only account for maybe 750 MiB of memory. Yes, I'm seeing root processes not just my own.When I first boot up, I'm already using 70% of my memory. This happens whether I run kdm/gdm and boot into KDE or Gnome. I'm running Ubuntu 10.04.installed 9.04 last year when I got the computer and then upgraded to 9.10 and then 10.04 without doing a clean reinstall

I have just upgraded to 10.04 and everything was working perfectly, until I upgraded my memory. I cannot boot from live USB / CD - these take me to the initial boot option menu, from which every option (except memory test) results in blinking cursor top left of screen, and cannot type.
Reinstalling my old memory sticks results in the system working fine. The new memory sticks pass memory tests (bios & ubuntu boot) with no errors whatsoever, and the boot sequence progresses fine until the point where the OS tries to boot. I am running AMD Athlon 64 3200+, Asus K8V Deluxe m/b. Memory that works is 2x 512mb PC3200 XMS. Memory that doesn't work is 3x 1gb PC2700 ECC. but please provide instructions on the basis that I know nothing, because I no practically very little about linux / ubuntu.

I am new to ubuntu and linux in general, I've been using it for about a week and I like it very much. The only problem is that I have an ipod touch and I purchase music and video from the itunes store from the device. I can import music but not the items purchased as it is encrypted so I need to use itunes. I installed virtualbox so that I could use xp (only to allow me to use itunes) but as I have a netbook with no disk drive I want to boot from a usb memory stick. Virtualbox doesn't appear to allow this so I am a bit stuck.

I run my linux server on the Fedora 11 x86_64 flavour of linux. It did have 1GB of DDR SDRAM PC2700 (Crucial) in the first DIMM slot. It worked fine, however i felt the need to add more RAM to the server. So I purchased 2Gb from Crucial 2 * 1Gb memory stick of DDR SDRAM PC2700 333 CL2.5. However when these are used the machine goes through grub begins booting and then hangs. Sometimes it goes through to the login screen where it hangs, othertimes it hangs after logging in. I have performed a memory test and the results come back fine. However if I just use a single stick of memory the server boots fine (Either stick of memory works).The Machhine is dual boot and my XP professional partition always boots fine

I just installed Debian on a new computer yesterday, it's more or less a fresh install. This morning I launched Iceweasel and it brought my computer to it's knees. I ran top, and found out that there was a process called "Web Content" using up 30 gigs of memory! Further experimentation shows that Iceweasel is fine until I open up a tab or two, and then it quickly begins consuming all my memory (I have 24 gigs) and swap space. I'm currently using Chrome, which is working fine, but I'd really prefer Iceweasel.

I have been using for over a year now, my 64-bit computer first with Fedora 8 and now with Fedora 10 with 2Gb of RAM just fine. Today I purchased an extra 2Gb for the system and upon installation from the GRUB screen Fedora 10 simply won't boot. It does boot with 3Gb, and it doesn't matter which stick I use for the 3Gb configuration, or what slot do I put the sticks into the motherboard, however if I place the four sticks, F10 simply won't boot. Should I pass a command line argument tot he kernel? If so, which?
