No drives available while booting

[myme3project@gmail.com]

Hello Team,

I'm trying to use Synology NAS in place of WDS server.
I'm trying to boot Windows 10 .wim file.
I'm new to this technology and have tried many things to get this thing working.
However, I'm stuck at a step. Please help me out with this.
Everything goes fine and the Windows installation page appears, but after that it asks to Select a Driver and no Drives are shown. But when I click on browse, it is showing me Documents, Downloads etc.
I've followed http://ipxe.org/wimboot and http://reboot.pro/topic/20166-wimboot-fr...nux-setup/
I'm using pxelinux.0
The configuration I'm using is shown below.

where wimboot.ipxe is

#!ipxe
dhcp net0 && echo IP address: ${net0/ip} ; echo Subnet mask: ${net0/netmask}
kernel wimboot
initrd bootmgr bootmgr
initrd efi/boot/bootx64.efi bootx64.efi
initrd boot/bcd bcd
initrd boot/boot.sdi boot.sdi
initrd sources/boot.wim boot.wim

And moreover this thing works only in Legacy boot not in UEFI.
I would like to boot using UEFI.

Thank you in advance
