PXE-E53 No boot error means your server is trying to boot over the network using the PXE protocol. Most probably you have DHCP server running in your network thus server is getting an IP address and would like to boot but doesn't receive any boot files since I assume you don't have any PXE servers up and running currently. Check BIOS boot order and ...

The issue might be that you are not saving configuration. You should click back couple times and at the System Setup click finish and save the changes.

At least on Debian, the iPXE ROM images qemu uses are located at /usr/lib/ipxe and /usr/lib/ipxe/qemu, depending on which virtual NIC you're using in your VM. Download the iPXE source code, make your modifications to it, build the ROM images, and replace the standard images with your customized ones.

Have your computer's boot sequence configured as hard disk first, network second. In this case, if you erase the boot sector of your hard disk, making it unbootable, the computer will resort to PXE boot, because no valid boot devices are present. Simply zero the beginning of the hard disk: dd if=/dev/zero of=/dev/sda bs=512 count=1 Although, as @yagmoth555 ...

The behavior turned out to be a new ESXi (7.0+) "feature" (did not find public doc yet). That's to say, the ESXi installer would create a UEFI boot option and place it first in the UEFI boot order when installing to a machine with UEFI firmware.

This is a long-known bug in Shim/Grub. https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1813541 It occurs in proxy-configurations, where DHCP<>PXE. The shim is TFTP-hardcoded to DHCP and ignores PXE-option "next-server". Since you need a (Microsoft) signed version, you are in the hands of Ubuntu or Debian. But for years now this remains unfixed.

pxeboot.n12 is a BIOS NBP bootmgr.exe is a BIOS NBP bootmgfw.efi is a UEFI NBP but LiteTouchPE_x64.wim is not an NBP; the PXE firmware will fail trying to directly boot a wim file and it would go back trying to boot again... the booting sequence could be i.e. pxeboot.n12->bootmgr.exe->LiteTouchPE_x64.wim

Yes, you can copy files during Kickstart. Depending on when you copy the files in Kickstart, you may or may not be in a chroot environment. Your copy target might need to use the filesystem under /mnt/sysimage. Use the virtual console during install and play around inside the Anaconda environment. Inspect mount to see how your remote FTP is mounted so you ...

$ sudo nmap --script broadcast-dhcp-discover uses the script broadcast-dhcp-discover found here: https://svn.nmap.org/nmap/scripts/broadcast-dhcp-discover.nse you should replace: result_table["IP Offered"] = r.yiaddr_str with: result_table["IP Offered"] = r.yiaddr_str result_table["IP TFTP Server"] = r.siaddr_str Alternatively you could also use $ ...

I'd add also that you will need to set 'reply_threshold_seconds' property to '0' for some devices. I had to do this so my ESP8266 device would connect to my Mac. Otherwise, the bootpd service just would not respond.

Multiple DHCP servers are fine for failover. They are pretty common on enterprise networks. As long as they issue dynamic leases in different non-overlapping scopes, there is no problem.

You can use Ansible to boot your machines from network through their HP iLO interfaces, by using "python-hpilo" module. In order to do that you can use some Ansible roles such as: - name: boot from netwrok through HP iLO interface only if the system is an HP server hpilo_boot: force: yes #make sure what you are doing, it will reboot a running machine ...
