while i have bought the X1, i5 with SSD, and delete the orginal Q drive carelessly.

Then how can i bought the recovery disk with the factory setting?

Or how can i build the recovery disk by myself? thanks a lot.

Contact Lenovo Support, you can order recovery media from them.

If you have the original hard drive with an intact operating system, Rescue and Recovery should let you burn recovery disks yourself.
