Problem creating partitions

I try to create partitions with cl-install but the command does not recognize me

cl-install -d /dev/sda1:/:btrfs is this true?

Hi,
for btrfs you must use GPT partition table on the disk and create a BIOS_BOOT partition (10Mb for example).
With GPARTED, with flag bios_boot or with cfdisk with type BIOS GRUB or BIOS BOOT i don’t remember)

After just use cl-install -d /dev/sdaX where your partition is sdaX and BIOS BOOT will be automatically detected.
