SSD BOOT
Is this video any use to you? It helped me get my PI to boot from ssd.
pi@max2play:~ $ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 223.6G 0 disk
├─sda1 8:1 0 41.8M 0 part /media/usb0
└─sda2 8:2 0 223.5G 0 part /media/usb1
Or maybe you are trying to increase the size of the sda1 area? Cheers
