Beginners Guide: Migrating to SSD

[Rustproof]

Rotant, Great instructions.
These really helped, but there's just one thing. After migrating to an USB FlashDrive, will I need to keep the microsd in there? 

My file system is now on the other drive, but will not boot without the microsd.

Code:

NAME        FSTYPE  SIZE MOUNTPOINT LABEL
sda                29.9G
|-sda1              3.9M
|-sda2               64K
|-sda3                4M
|-sda4                4M
|-sda5                4M
|-sda6      vfat    112M            boot
`-sda7      ext4   29.8G /          rootfs
