ubuntu 22.04 PXE boot , after installation , physical machines just won't bootfrom harddisk

Question

it's really odd. after couples of playing around with ubuntu 22.04 .I have made two ISOs that can be install ubuntu 22.04 server/desktop automatically.

now I'm trying to configure my old PXE server to install ubuntu 22.04 automatically. I first try netboot.xyz which provide sanboot command to boot from ISO file. well , it works in virtual machine ( proxmox ) , but not physical machines ( an acer desktop , a lenovo T470 laptop) I soon decided to give up ipxe , I need more time to study the ipxe.

so I go back to my old but stable PXE server , which already provide ubuntu 18.04,20.04 desktop/server with/without preseed file.

it's not that hard to make ubuntu 22.04 boot with PXE and auto install , here is my configurations.

pxelinux.cfg/default

label Ubuntu 22.04 Server auto install
menu label Ubuntu 22.04 Server auto install
kernel tftp://192.168.11.7/images/ubuntu/22.04/amd64/vmlinuz
initrd tftp://192.168.11.7/images/ubuntu/22.04/amd64/initrd.gz
append ip=dhcp cloud-config-url=/dev/null url=http://192.168.11.7/jammy-server/ubuntu-22.04-live-server-amd64.iso autoinstall ds=nocloud-net;s=http://192.168.11.7/jammy-server/

label Ubuntu 22.04 Desktop auto install
menu label Ubuntu 22.04 Desktop auto install
kernel tftp://192.168.11.7/images/ubuntu/22.04/amd64/vmlinuz
initrd tftp://192.168.11.7/images/ubuntu/22.04/amd64/initrd.gz
append ip=dhcp cloud-config-url=/dev/null url=http://192.168.11.7/jammy-server/ubuntu-22.04-live-server-amd64.iso autoinstall ds=nocloud-net;s=http://192.168.11.7/jammy-desktop/

they are almost the same , besides the last part ( where the user-data/meta-data stores ) so , with this configuration , I create a new VM in proxmox , boot from PXE and select to install desktop without any problems.

the install process takes about 12-15 mins , after the first reboot , I can see the ubuntu login screen.

After the success on the VM, I continued testing with the physical machine well, the install process also runs without any problem , but after rebooting , these physical machines just won't get into ubuntu, but no error messages , no matter server/desktop I choose. but I'm pretty sure the installtion "completed" , so I boot the machine with Live USB , then pack /var/log/installer , and try to check what's the matter here is the installer log files.

I have no idea why the same configuration works in VM but hangs in desktop/laptop .I really have no any clues.

Any comments and suggestions will be appreciated.

update 2022/06/23 I think it's something related to bios/EFI booting issue I didn't configure storage layout in user-data , just use the support layouts in documents

storage:
  layout:
    name: direct

according to the URL https://ubuntu.com/server/docs/install/autoinstall-reference

The two supported layouts at the time of writing are “lvm” and “direct”.
By default these will install to the largest disk in a system

but it didn't create any ESP partitions. this is the disk layout in VM after PXE auto install

I could add custom storage layout to add ESP partition , but in 22.04 , it's really a disaster to do so. I have to write many configurations for different type of hard drive. (/dev/nvme0n1 , /dev/sda , /dev/vda ) or otherwise the install process will fail.
