Since I was unable to find a specific answer to how can one create a Dell recovery disk from within Linux, I decided to write the steps here.
If you write the CD image directly to the USB drive (or create a new partition and write it there), the laptop will not boot. You need your USB media to be in FAT32 format with the contents of the recovery ISO.
$USB_DEVICE is your USB drive (check with fdisk -l, it may be

SchemaSpy is a neat tool to produce visual diagrams for most relational databases.
