The Linux system on the USB drive will recognize the large ext2 partition as the "casper-rw" persistence space, and will use it, so you can have 10 GB of persistence space if you're using a 16 GB drive.ĭanYHKim wrote:Persistence is maintained in a file called "casper-rw". Using GParted, create a large ext2 partition on the USB drive (filling the remaining space, if desired). Now, mount the USB drive somewhere and delete the casper-rw file in the FAT32 partition.ĥ. Install Zorin-OS to the FAT32 partition of the USB drive using Unetbootin, specifying a small persistence file (2 MB is enough).Ĥ. Also, if you wish, create a 1 GB swap partition.ģ. Create a small partition formatted FAT32 (3 GB is plenty). Delete partitions on the USB drive using GParted.Ģ. It turns out that one can get around this by creating an ext2 partition on the USB drive that is named "casper-rw", to substitute for the persistence file. Because the USB drive is formatted FAT32, the "casper-rw" file is limited to 4 GB, which can quickly be too little. Persistence is maintained in a file called "casper-rw". Now open the app Unetbootin and you need to point the installer to your downloaded ISO file, click where it states " Disk Image": THE USB STICK MUST BE MOUNTED BEFORE YOU START USING UNETBOOTIN!!!. Do not just simply delete what files are on the stick as the hidden files are exactly that "hidden"!. Now, you will need a USB stick/Pendrive of not less than 4 - 5GB in size for a good safe install, the drive must be PRE-FORMATTED TO FAT32 file format ERASING ALL DATA PREVIOUSLY KEPT ON THE DRIVE INCLUDING HIDDEN FILES!. It can create a dual-boot install, or replace the existing OS entirely. UNetbootin allows for the installation of various Linux/BSD distributions to a partition or USB drive, so it's no different from a standard install, only it doesn't need a CD. Sudo apt-get install unetbootin or the Windows version: Install the app Unetbootin either under Linux: Code: (I am not talking about using the Unetbootin download function, I am talking about you downloading your ISO directly from a website!, please see below for instructions how to use the onboard download function!.) Firstly, download your preferred version of Zorin OS, 32 or 64 Bit (if you are unsure, download the 32 Bit version) (Ubuntu/Debian/Voyager/PinguyOS etc) in the form of an ISO file, remember where you store the file!. Gotoptions = -reference=/root/live/gitcache Next, from a shell terminal, change to directory '/usr/local/src/pybombs_legacy' and do the following: 'sudo apt-get dist-upgrade'), the USB drive will no longer boot if you do!ĩ. You can now use apt-get to install and/or upgrade standard packages if you wish. To eliminate errors when updating using apt-get, open a shell terminal, and enter the following commands: Setup networking, and set the correct timezone/date/time.Ĩ. Linux /casper/vmlinuz.efi file=/cdrom/preseed/ed boot=casper quiet splash - persistentħ. Set menu_color_highlight=black/light-gray I remove other entries from the boot menu as well, so my grub.cfg file ends up looking like this: Edit file \boot\grub\grub.cfg on the USB drive to add persistence (if running Windows, don't use Notepad, use Notepad++, or another editor that preserves the original unix file format). When finished, eject and then re-insert the USB drive (do not boot from it yet).Ħ. * Insure 'Type' is set to 'USB Drive', and 'Drive' points to your USB drive.ĥ. * Set a value for 'Space used to preserve files across reboots' (I use 2000 to enable 2GB of persistent storage). * Click on 'Diskimage', insure the dropdown menu is set to 'ISO', and select the GNU Radio ISO file downloaded previously. Use unetbootin to create the bootable USB stick: (If you are running Linux, you should be able to do something like 'sudo apt-get install unetbootin').Ĥ. On Windows, download the unetbootin utility from: Insure that the maximum size of the stick is 32GB (or the first bootable partition on a larger USB drive is 32GB or smaller).Ģ. You have at least a cursory familiarity with Ubuntu, including how to setup networking and how to edit files (using vi, gedit, etc.)ġ. I thought that I would post a brief summary of the process that I used to create a bootable USB drive to run OP25.
