i downloaded your 39 MB BOOT software and extracted it , but how does one install it , there is no folder given in it

Don't extract the ISO file, burn it to CD using Windows image Burner or ImgBurn. Then boot the CD, follow steps given.

How to Boot your Computer from a Bootable CD or DVD

ok so i have now booted from CD. it opens up partition wizard , but as shown in your videos (no audio) , when i select my E drive to make it primary. it does not give me that option "Set partition as Primary" , while it is giving me that option in C & D drive

Try converting D to Primary first, which should enable E to also be converted to Primary.

The problem is that D,E and F are Logical so converting E would break up the Logical extended block which is not allowed since Logical partitions must remain contiguous.

i made my E drive primary and set it to active succesfully

then click on Disk # to highlight it, from Disk tab select Rebuild MBR, OK, Apply

now i didnt understood this next step. what is disk # ?

How to click on the Disk # is the very first thing shown in this Help video: How to Rebuild MBR with partition magic? Partition Wizard Rebuild MBR Video Help.
