# Use GUI: it handles Wifi better!

# Check the devices and it's partitions:
lsblk # to check the device names and sizes

# If under /dev/sdc and mounted:
sudo umount /dev/sdc1

# Put the OS image on the USB stick:
sudo dd if=nixos.iso of=/dev/sdc #

d # first, delete all partitions with `d`
o # create a new GUID partition table (GPT)

## Create the BIOS boot partition
n # create new partition
1 # partition number
ENTER # use default first sector
+1M # partition size of 1MB
EF02 # set partition type to "BIOS boot partition"

## Create the EFI System Partition
n # create new partition
2 # partition number
ENTER # use default first sector
+500M # partition size of 500MB
EF00 # set partition type to "EFI System"

## Create the Linux LVM (where LUKS goes)
n # create new partition
3 # partition number
ENTER # use default first sector
ENTER # partition size is the remaining of the disk
EF00 # set partition type to "EFI System"
8E00 # set partition type to "Linux LVM"
