I downloaded Endless os full(12.8 Gb) .xz file. Now how i install it via usb.
Hi @Kishor_Nale, if you have Windows you can use the endless-installer.exe to make a dual boot install or create a bootable Endless USB. If you have Linux you can make a persistent live USB (basically Endless installed to the USB stick) with the instructions at https://support.endlessm.com/hc/en-us/articles/210654503 but this doesn’t let you boot and then install Endless.
It’s actually a little harder to create a combined live+installer USBs from under Linux at the moment because it uses a couple of different scripts and needs exfat-utils which isn’t always available on all Linux systems. If you want to try, you can fetch the relevant scripts from Git, and run them. This is known to work on Fedora 24 (with a caveat, see below); it should work on Debian and Ubuntu:
git clone https://github.com/endlessm/eos-meta
cd eos-meta/eos-tech-support
sudo eos-write-live-image --os-image /path/to/eos-eos3.0-....img.xz --latest /dev/sdd
You should replace /dev/sdd with the right device name for your USB key. You’ll need to have a number of standard Unix tools installed, plus support for creating and mounting exFAT partitions. The latter is likely to be the most problematic: Fedora, for example, does not distribute exfat-utils, so you need to install it from somewhere else, like rpmfusion.
