How to install Juniper OS Step by Step
For juniper OS instalation you must login as a root.
Copy your OS to a USB drive.
Insert the USB drive to Juniper device. USB drive must be formated by FAT32. NTFS will be not mount.

[Here you can see the all partition of HDD also a new partition will arrise here]
root@:RE:0% mount_msdosfs /dev/da1s1 /mnt/
[You need to mount your USB drive to /mnt directory. Here my new USB partition is da1s1, It can be diffrent for depend on hardware]
root@:RE:0% ls /mnt/
[Your USB mount is completed to /mnt. You can see with above command]
root@:RE:0% cp /mnt/jinstall-ex-3300-11.4R2.14-domestic-signed.tgz /var/tmp/
[Copy the Juniper OS file to /var/tmp directory]
root@:RE:0% ls /var/tmp/
[Confirm with avobe command to copy of file is finished or not]
root@:RE:0% umount /mnt/
root@:RE:0% umass1: at uhub1 port 1 (addr 2) disconnected
(da1:umass-sim1:1:0:0): lost device
(da1:umass-sim1:1:0:0): removing device entry
[Now you can unmount to USB dribe. After avobe command you can remove your USB Drive from your device]
root@> request system software add /var/tmp/jinstall-ex-3300-11.4R2.14-domestic-signed.tgz no-copy no-validate reboot
[With this comand instalation process will be start]
[no-copy mean after instalation JUNOS it will remove the current OS file from /var/tmp]
