I have got the solution :
rm -rf /etc/pve/qemu-server/111.conf
nano /etc/pve/qemu-server/105.conf
##### For Linux It should be :
bios: seabios
boot: order=scsi0;net0
cores: 2
memory: 4096
name: saurabh-nfsc
net0: virtio=A2:B3:C4

5:E6:F7,bridge=vmbr0,firewall=1
scsi0: local-lvm:vm-105-disk-0,iothread=1
scsi1: local-lvm:vm-105-disk-0,iothread=1
scsi2: local-lvm:vm-105-disk-0,iothread=1
scsihw: virtio-scsi-pci
##### For Windows it should be :
bios: ovmf
boot: order=scsi2;scsi1;scsi0;net0
cores: 2
memory: 4096
name: CleanWindows10
net0: virtio=00:11:22:33:44:55,bridge=vmbr0,firewall=1
scsi0: local-lvm:vm-100-disk-0,iothread=1
scsi1: local-lvm:vm-100-disk-1,iothread=1
scsi2: local-lvm:vm-100-disk-2,iothread=1
scsihw: virtio-scsi-single
Enjoy !!
