why i can't install redhat 7.2 in harddisk setup model

[Wardong]

hi all;
i had downloaded 2 iso disks of redhat7.2,and save them in the partition E(windows,FAT32 format),copy dosutils from the first iso file,then save them with the iso files,restart my pc to dos model,then E:[enter],cd dosutils[enter],autoboot[enter],but it can't install,i don't konw why
does this setup model has some special request of hardward?
what setup changes should i do to the mainboard?

THe harddisk installation mode is not like that.
The correct steps:
1.Copy the isos to a FAT32 partition(for example E:, /dev/hda6)
2.Make a bootable floppy disk using the first iso.(use rawrite.exe),you can find the floppy image in the first iso
3.Boot using the floppy disk you made.
4.When install program ask you for install media, select hard drive and specify the partition, /dev/hda6.
5.Then it begins
