• Install Debian On Usb Drive From Windows

I would like to install debian 9 onto usb but not sure how to do it. I currently use debian 8 on my desktop which was installed by a friend.

1. UNetbootin allows you to create bootable Live USB drives for Ubuntu, Fedora, and other Linux distributions without burning a CD. It runs on Windows, Linux, and Mac OS X.
2. I was reinstalling my desktop (long story), and I inadvertently left a USB Flash Drive plugged in as well as my SSD. It seemed like a totally normal install, just inexplicably slow, but it was very late, and I was drifting in and out of sleep in my chair as I was sitting at my desk waiting for it. Installing Debian on a.

I've got a shining new x64 laptop running Windows 7 and I want to dual boot Debian stable.

I've installed Ubuntu on loads of laptops in the past using a USB drive, but I can't find decent instructions for installing Debian like the Ubuntu instructions.

I've installed Debian from CD a couple of times in the past too, but my new machine doesn't have an optical drive.

The questions are:

1. Which files do I need from theDebian download page?

2. How do I make the Debian files on a USB drivebootable?

3. Does the Debian installer have a disk partitioner (like theUbuntu one does)? Reading the installation guide it seems not to,which would be another hurdle. If this is the case, which partitioner can I use?

Download UNetbootin, which allows one to create bootable USB installation media for almost any Linux and BSD distribution out of the box.

Just run it, select Debian, choose the usb drive and wait while it downloads the .iso and transfers it to your usb. After that it's bootable and the install works like from a CD.

If you're on Linux, the easiest way is to simply do (as per the docs):

Where X is your drive letter, you can find out the correct letter by checking the output of dmesg right after connecting your USB device. For example for me (and probably many) it would be /dev/sdb

This will wipe everything from your USB drive, so be careful!

UPDATE:

For completeness, I should also mention Rufus for Windows.

1. Open Debian Download page and download the right cd / dvd for your pc. Most likely, if you have a modern computer, you'll want amd64 version. I'd suggest to choose cd because today you'll probably have a broadband connection and you'll be able to download other needed packages later very quickly.

2. If you use Linux terminal you can use dd to prepare your usb stick (iso filename in this command is just an example, you'll have to use your downloaded iso name and path:

   dd if=/your/path/debian-7.5.0-i386-netinst.iso of=/dev/sdX bs=4M
   sync

See Debian official instructions here.

_{Edit: added sync, to flush device writes before ejecting the usb device.}

3. Modern Debian versions include a partitioning tool and wizard, the process should be fairly easy, as pointed out in all the guides, here's one.

So far the easiest way I have found is

Where X is the drive letter assigned to the devise (see dmesg right after inserting the USB)

As seen in the Debian instructions

You can try EasyBCD to boot from the iso file directly without creating a bootable usb

4.3.3. Manually copying files to the USB stick — the flexible way (Debian Official Ref.)

After trying other options and some notebooks refusing to boot, I've tried this 'flexible way' and it was the only one that worked for me.

1. Stick your new USB stick to the USB (a new one or one that you don't care to lose all data).

2. unmount it, if it has mounted automatically

   • umount /dev/sdX1 (and sdX2, ...)

3. partition it (i like old-fashion fdisk)

   • fdisk /dev/sdX
   • d to delete all partitions
   • n to create a new, using all space
   • t to change the partition type to ID c: W95 FAT32 (LBA)
   • a to make sure it is bootable
   • w to write the changes and exit

4. Install an MBR with (I didn't need this step, so you may test. But its no harm to use it):

   • install-mbr /dev/sdX

5. Create the filesystem

   • mkdosfs -F32 -n 'Debian85' /dev/sdX1

6. Keep it unmounted and generate the system in it:

   • syslinux /dev/sdX1

7. Lets mount the USB stick:

   • mount /dev/sdX1 /mnt/d2/

8. Copy some files (be certain you download them from hd-media):

   • cp vmlinuz /mnt/d2
   • cp initrd.gz /mnt/d2

9. Edit the file syslinux.cfg, and add the following content to it:

   • vim /mnt/d2/syslinux.cfg

10. Copy the ISO image to the USB stick:

    • cp /some/path/debian-live-8.5.0-amd64-kde-desktop.iso .
    • sync

11. Unmount the stick and it is ready to boot some machines:

    • umount /mnt/d2

Notes:

1. If at some point you become confused about what is mounted where, don't forget to run:

lsblk -fo +size

2. A comment from my experience: if you copy the files on step 8 from your mounted ISO CD image instead of from the hd-media, then, after a successful boot, during the beginning of the installation (step 'Detect and mount CD-ROM'), it will show you the message:

   'incorrect cdrom / cdrom detected cannot be used for installation'.

Googling it may show you problems with unetbootin, but as you can see, this method gives the same error and doesn't use such program.

3. Also, as this method keeps the USB stick available space after the process usable, it is a good idea to create a folder (use the name firmware so debian can find it during the install) and add to it all sorts of non-free firmware that may be needed during the installation. You can get them from this unofficial netinstall image.

Debian.org - 4.3. Preparing Files for USB Memory Stick Booting

4.3.1. Preparing a USB stick using a hybrid CD or DVD image

Debian CD and DVD images can now be written directly to a USB stick, which is a very easy way to make a bootable USB stick. Simply choose a CD or DVD image (such as the netinst, CD-1, DVD-1, or netboot) that will fit on your USB stick. See Section 4.1, “Official Debian GNU/Linux CD/DVD-ROM Sets” to get a CD or DVD image.

The CD or DVD image you choose should be written directly to the USB stick, overwriting its current contents. For example, when using an existing GNU/Linux system, the CD or DVD image file can be written to a USB stick as follows,

4.3.3. Manually copying files to the USB stick — the flexible way

If you like more flexibility or just want to know what's going on, you should use the following method to put the files on your stick. One advantage of using this method is that — if the capacity of your USB stick is large enough — you have the option of copying any ISO image, even a DVD image, to it.

Regarding the boot loader for MS FAT formatted file system.

To quote from the Very Verbose Debian Installation Walkthrough:

Step 3 � (cfdisk) You should now be at a black screen that says, 'cfdisk 2.11n', at the top. This is where we will partition our hard drive to prepare it so we can install Debian. Probably one of the most 'scary' tasks when installing Debian is partitioning the drive. Debian uses a command line tool called cfdisk, which is really quite simple to use, so don't be discouraged by its monochrome presentation.

This will hopefully be useful to others.

At present, the official FAQ about Debian install CDs - https://www.debian.org/CD/faq/#write-usb (alongside the usual Linuxy methods, which are nice until you're on a Windows-only machine) - also suggests Win32DiskImager, a simple GUI-based program to write bootable images (such as the Debian .iso) to USB: http://sourceforge.net/projects/win32diskimager/files/latest/download

Install Debian On Usb Drive From Windows

I've used this method to install latest x86 and x64 Debian with no issues whatsoever.

An alternative method:From your question, I don't see any specific reason why you would want to put Debian onto a USB stick (if there's one, correct me). If you really just want to dual boot Debian on a machine running Windows 7, the Win32-Loader offers an easy way to do so. One can grab this from any debian mirror, inside the directory debian/tools. It's easy to use and self explaining. Once executed, just set the options to your needs (things like keyboard layout are automatically detected) and then click the install button. The setup will download the needed files and then allows you to directly boot into the installer, without the need for making an USB stick bootable and copying a lot of files on it.And yes, the Debian installer offers a way to partition the disk.
