I've not been able to reply to the comment because of time although I did read them but I was so lazy to reply them but I think I should just do that today because I have another current ongoing issue, I will create a new thread for that
Debian or Xfce or Tails are the options that will work for you on that old computer and it is better to use Tails.
- Delete everything on the memory, delete Windows and make sure to format everything.
- Remove all the connecting parts from the network cable to the Bluetooth.
- burn Tails on your computer and use electrum to generate the addresses and MPK.
- Save the wallet seed on a piece of paper or a metal piece.
- import the MPK to the wallet on your phone.
You can find more information here or by searching on Google for tails electrum cold storage

Chikito and Dragonfund have guide threads on Tails OS too.
I will also go through this too , thank you for the links.
Proper, safe and redundant backup of your mnemonic recovery words and what other details about your wallet are helpful for any later recovery is mandatory. Personally, I would also setup a fully encrypted filesystem for the cold storage, so that a possible theft of the cold storage device doesn't compromise your private keys. Of course, don't ever loose the filesystem's encryption passphrase. Redundant and safe backup for it is key, too!
So I will have to keep both passphrase and mnemonic word cold too... any suggestion of a safe way to do that.
