[ILUG-BOM] installing linux from hdd

i have a linux 7.1 installed along windows managed by lilo while upgrading to rh7.3 the cdrom cudnt live upto it and stops reading midway. this messed up my earlier installation.

i got rh7.3 cds dumped on my hdd e:\rh73 (which is /dev/hda6 iguess) tree is soemthing like this e:\rh73 -> images -> dosutils -> RedHat -> RPMS -> base etc

i started the installation from command prompt using autoboot.bat a part of dosutils

now installation starts and asks me to select partition and then enter directory names. i have tried every possible dir names and partition name

plz tell me how to identify / specify directory names holding installation files..

take care harsh
