The "rescue image" is on the install CD/DVD that you just booted.
The process is now general enough that you could have booted
from boot.iso, pxeboot, usb stick or other image, which contain
only enough to boot, and not enough to perform rescue operations.
In those cases you need to find the rest of the rescue software,
which might be on nfs, http, ftp, CD/DVD, harddisk, ...

Re-load the install CD/DVD, which contains everything needed for
rescue mode.  Rescue mode should proceed.  [You might have booted
a boot.iso CD-ROM in order to get a recent Linux kernel, but still
have the rescue software on another platter (which might be older,
for instance.)]

The ability to use an install CD/DVD for rescue mode is new.
The ability to use the rescue CD-ROM as an installer also is somewhat new.
