Once you have started booting into install mode, you cannot switch to rescue
mode. You specify the "rescue" at the boot prompt.
The original question was how to do this with pxe boot. The answer is to
have a second (or separate) entry in the
/tftpboot/linux-install/pxelinux.cfg/default file that specifies the
"rescue" option and have a corresponding entry in the
/tftpboot/linux-install/msgs/boot.msg file so you have a menu entry to
activate the rescue mode. My boot.msg and default files are setup so I can
select to install from one of four versions of Red Hat Enterprise Linux or
boot into rescue mode from three of those versions:
/tftpboot/linux-install/pxelinux.cfg/default:
default local
timeout 100
prompt 1
display msgs/boot.msg
F1 msgs/boot.msg
F2 msgs/general.msg
F3 msgs/expert.msg
F4 msgs/param.msg
F5 msgs/rescue.msg
F7 msgs/snake.msg
