|"This Recovery partition can recover the whole computer system even when the computer is "completely death", right?"|
If the PC is "completely death", how are you gonna access the HDD to run the recovery?
"Why don't they just send the recovery CD/DVD in the first place is beond me"
No one ever reads the instructions, but the buyer is supposed to create the Restore CD's ASAP after getting the PC. It's a one shot deal...if the discs get lost or damaged, you can't go back & create another set. You have to contact the manufacturer for replacements.
