I have Librem 13v4 set up with Coreboot/Heads and also LUKS decryption via Librem Key as outlined here. I have run into some roadblocks with PureOS and would like to format the drive. My problems mainly stem from an inability to access and manage cryptocurrency. I can’t install a chromium based browser, can’t use add-ons in PureBrowser and also can’t get Monero wallet to run. I have made a number of changes to PureOS including adding Debian repositories, installing qt to build Monero. It still doesn’t work and I have no idea how to undo what was done. Boxes does not recognize my hardware wallet so I plan to try getting these things working in a less customized distribution like Mint or Ubuntu. I have backed up files and tried to simply load the Mint ISO image on USB through Heads but it just rebooted Heads. I do like PureOS (other than no browser extensions) and plan to continue using it and ideally I would like to create two partitions on the drive (500 GB NVMe) and run a dual boot setup with PureOS and a smaller Mint/Ubuntu partition to manage cryptocurrency but I figured I would ask for guidance first regarding how to go about this. Specifically:
Do I need to do anything about the hard drive encrypted through the Librem Key prior to formatting?
Can I format and partition the drive through Heads or should I revert to seaBIOS/coreboot first? Once dual boot is set up could I go back to Heads with Librem Key?
Will I have to abandon Librem Key decryption for LUKS on the drive or is it possible to decrypt LUKS with Librem Key on the PureOS partition or both partitions?
Is there anything else to consider that I am missing?
