Kickstart Fedora server iso using usb

Hi I need to create a Fedora Server image with my application in it using kickstart installation. I have executed following steps :

1. Downloaded the fedora35 Image from https://getfedora.org/en/server/download/ (Fedora-Server-dvd-x86_64-35-1.2)
2. mount the iso : mount -t iso9660 -o loop Fedora-Server-dvd-x86_64-35-1.2.iso /mnt/
3. mkdir /var/iso
4. cp -a /mnt/ /var/iso
5. cd /var/iso/
6. vim ks.cfg (contents of the ks file are below) : this file is auto generated while manual fedora install.

7. vim isolinux/isolinux.cfg Added the label kickstart and made that default:

default kickstart

label kickstart menu label ^Testing for device kernel vmlinuz append initrd=initrd.img inst.stage2=hd:LABEL=deviceimage inst.ks=hd:LABEL=deviceimage quiet

8. genisoimage -U -r -v -T -J -joliet-long -V "deviceimage" -volset "deviceimage" -A "deviceimage"
   -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table
   -eltorito-alt-boot -e images/efiboot.img -no-emul-boot -o newfedora.iso ../mountedIso/ (the above command is executed in single line)

9. scp the fedoraimage from the machine to widnows and using rufus 3.17 making a bootable usb

10. using this usb on device.

Problems statements :

1. When running on the virtual machine it installs properly but when trying on hardware it gives error on Installation source and Installation Destination.

2. When I remove the parttion info from the ks.cfg and enable autopart then Installation destination does not appear but Installation source remains same.

Please guide me for the abouve issues.
