¶ Everything PXE boot
¶ Story of my life
Here I tell the sad and tragic story of my life with UEFI PXE boot
1. If I choose the wrong installation ISO, it will not work
Rufus must burn an uefi installation, and
this option is only present when the ISO is UEFI-windows
2. If I send the wrong DHCP options, it will not work
Do not use option 150 (cisco propretary) or Vendor-code (which is wrong)
Useoption 66 ip 10.0.0.1and
option 67 ascii syslinux.efi
3. If I use an old tftp server, it will not work
Oct 26 21:11:30.992: TFTP: Opened flash0:syslinux.efi, fd 10, size 193230 for process 33
Oct 26 21:11:30.992: TFTP: Sending block 1 (retry 0), len 512, socket_id 0x218D5EA4
Oct 26 21:11:30.992: TFTP: error code 4 received - 21875
Oct 26 21:11:30.992: TFTP: Finished flash0:syslinux.efi, time 00:00:00 for process 33
4. If I use the the wrong PXE-image, it will not work
PC will crash and hang
5. Life continues...
¶ 0. Design Decisions
- I choose UEFI boot,
- built in NIC driver &
- has IPv6 support
I Choose iPXE (formerly gPXE) becouse it is used by FOG
¶ 1. Partition HDD with EFI partition
Use Windows .ISO and Rufus
1. Download the PROPER ISO image of windows, that has eufi (install) boot option 2. Open .iso in Rufus and make shure that it is saysGPT and UEFI (non CSM); otherwise you have downloaded the wrong .ISO
3. After installing (next next next) you should have
and
¶ 2. Change BIOS to UEFI with PXE-boot
¶ 3. Configure Router DHCP for PXE-boot

1 File not found.
2 Access violation.
3 Disk full or allocation exceeded.
4 Illegal TFTP operation.
5 Unknown transfer ID.
6 File already exists.

Using BIOS, the file transfer works; but the PC crashes instead !?!
¶ 4. What file to use and how to tftp it ??
Discarded https://en.wikipedia.org/wiki/SYSLINUX even though it has nice graphix
You can use HTTP boot (not tftp) so only a web-server is needed
https://ipxe.org/appnote/uefihttp
DOWNLOAD ipxe.efi-file from above URL and " iPXE binary (e.g. ipxe.efi) "

¶ Nice reads, with pictures
https://github.com/ipxe/ipxe/issues/517
https://forums.fogproject.org/topic/12132/pxe-boot-fog-menu
for bios mode you can use ipxe.pxe or undionly.kpxe
for uefi mode you can use ipxe.efi or snponly.efi
What you do have configured for dhcp options 66 and 67. Also be sure you don’t have dhcp option 60 set.
