Using Electrum and Bootable Ubuntu USB to Create a Secure Cold Storage Wallet
Here is a short guide that is hopefully newb friendly for creating a cold-storage wallet with Electrum. All you will need is at least one USB flash drive with at least 2 GB of free space, your PC, and pen & paper.
The first step is to create a bootable Ubuntu flash drive. Ubuntu is a free open source Linux distribution that is very newb friendly, don't be intimidated. Assuming you are a Windows user just follow, these directions on how to make a bootable Ubuntu USB drive.
You will need The Universal USB Installer, as well as the Ubuntu .iso image file. Choose the 32 bit version to be safe. Download both, plug in your USB flash drive, and launch the installer. Select Ubuntu in Step 1 in the installer. Then in Step 2 browse and locate the Ubuntu .iso image file you downloaded. Then in Step 3 select the drive you have inserted, as well as click the box to format the drive and erase contents. Do NOT set a persistence as this will reduce the security. Then click create and wait for it to finish.
Once done creating your Ubuntu bootable drive, you will shut down your computer. Then with the USB stick plugged in you will boot the computer up. The computer should boot into the Ubuntu stick instead of your regular hard drive. If it failes to do so, then when booting press F4 or other command to enter BIOS menu. Then go to boot order options and change the boot priority so that it boots to an external/usb device first before the main hard drive.
Once booted into Ubuntu, make sure to click "try ubuntu". You are only trying it out on the USB, and not installing it onto your main hard drive. The reason for using the bootable drive is everything exists in memory and mostly disappears when you shut down Ubuntu.
Once booted, you can connect your internet connection to download Electrum. Go to the software center on the left side bar, it looks like an orange shopping bag. Search for "electrum" and then download and install Electrum. After this its very important to DISCONNECT the internet and NEVER turn it back on until you shut down Ubuntu.
(It would be more ideal to install electrum in a complete cold environment, but I have heard that could cause some problems with Electrum at this time and it is best to install it while connected to the internet. But if you want true cold storage you must have zero internet connection at the time of creating the wallet. Since we are disconnecting before Electrum creates the seed, we should be good.)
Once the internet is disconnected, then go ahead and launch Electrum. Choose the option of creating a new wallet, and write down the seed phrase on paper. Also record some of your public addresses. Also you can enlarge electrum to the entire screen then click on "wallet" on the top left, then click "Master Public Key", and you can copy the Master Public Key which will allow you to reconstruct all of your addresses for that seed. The Master Public Key can also be used to create a watch only wallet in Electrum, just choose "watch only option" when creating the wallet and when prompted enter your Master Public Key.
At this point you are done, just shut down Ubuntu to make sure the evidence of the seed is erased. Then you can send Bitcoins to your cold storage wallet. You have effectively created a very secure cold storage wallet, in my opinion. To restore the cold wallet, just launch electrum and choose "restore wallet" option, type in your seed, and voila you have a hot wallet ready to spend again. Extra:Using Truecrypt Encryption Bonus tutorial is if you would prefer to save your seed on another USB or digital device. It is not recommended to do this, unless the seed in encrypted. Even then I would only leave it on a USB and not plug it into any hot device just to be safe. I would recommend Truecrypt although its possible the NSA has hacked Truecrypt, so use at your own risk.
To install truecrypt on Ubuntu, I have found this seems to be the best method using the PPA by Stefan Sundin. Open a terminal and execute the following commands:
Hit enter after each command. If it asks permission, press y. Sometimes I had problems getting commands to work in the past. For some reason first installing flash from the software center fixes the problem, but I have no idea why.
Once installed then just type "truecrypt" in the terminal and press enter, and truecrypt will launch. Then go ahead and click the create volume button. Choose create an encrypted file container and click next. Click Standard Truecrypt volume and click next. Then select a name and location for your file and click next. Then I usually choose AES-TwoFish-Serpent encryption algorithm and RIPEMD-160, then click next.
Choose a size for the file, probably 5 MB is enough, but by all means choose more if you want to hold more files. Click next and make sure to choose a SECURE password for the file. If you don't pick a good enough password it will be brute forced easily. Use numbers, letters, capitals, lowercase, symbols, and make it long as possible. Try to have it something you can memorize if possible. Then click next. Then format it as FAT, and click next. Move your mouse around for entropy and then click Format, and your truecrypt container has been created.
Then click exit, and go back into truecrypt's interface. Click the first slot in the rows, and then click "select file" underneath. Choose the file container you just created. Then click mount and type your password to mount the container. Once mounted you have access to the container and can drop files inside, and access the contents as well. Once done, dismount the file, and save it where appropriate.
I think this is a decent easy to follow tutorial. Hopefully this can help some newbies out, if I made any mistakes please feel free to correct me. Edit: Sorry formatting sucks.
