This is to reset your nexus to complete stock like the day you bought it, so yes you will loose all data!

First follow the YouTube guide to install android sdk, adb, fastboot on computer.

Then follow this guide to reset your nexus.

Note the bootloader needs to be unlocked which once adb is set up as in guide below the first comand needs to be

Fastboot oem unlock

The guide doesn't mention this.

When you have finished

Fastboot oem lock. Will lock your bootloader again.

Did you follow the YouTube video fully? I had to add some paths to windows too.
You can leave the "fastboot oem unlock" command until just before you flash the operating system back on, if you forget and try to flash the operating system it doesn't matter it will just tell you the bootloader needs to be unlocked, this is the part where a small amount of poo came out of me because I had followed the guide past where you use all the erase commands and then though **** how do I unlock my bootloader now everything is wiped! Turns out the fastboot command still works.

No way... i think its not detect on my Windows nor on Ubuntu. Better i think, gave it to authorized service centers.
