I currently have a Live USB with Ubuntu 12.04 on it and my Laptop is a Windows 10 machine.
I would like to remove Ubuntu 12.04 and use Tails instead. The reason I want to use Tails is that I am planning on storing my Cryptocurrency Wallets on Tails and tails is recommended for this due it having Electrum.
If Tails is not necessary for this can you please let me know how I can upgrade to the latest version of Ubuntu safely without damaging my Windows 10 OS.
Thank you
