Normaly winboot is used to boot into winpe, which has worked for quite some time...

There is one or 2 other patches from Vishvananda Ishaya Abrams which you might want to apply, most of them from December.

Thanks for the pointers. Since I'm not a developer I don't think I'm up to the task of building iPXE with patches. I've been using rom-o-matic.eu to build snponly.efi. I suppose I can wait until rom-o-matic catches up to the various patches related to iBFT and executable boot.

I'm not a developer but happy to help out with testing if we can generate using the rom-o-matic

I would strongly urge you to get a machine where iPXE can be built from sources and apply patches. Testing is done by building yourself not via rom-o-matic since it's output unfortunately is to unreliable to use for debugging.

Starting a virtual linux livecd is not hard at all, or even installing on a virtual machine.

Sad
the last ipxe seems can support uefi iscsi boot. I try it, it is really can boot winboot and winpe, but can't install windows operate system on it.
is prompt has no iBFT found. like the attached picture.
any one fix this bug.

Correct that it is currently missing, as mentioned above, a patch for this has been sent to the mailing list and is available at http://lists.ipxe.org/pipermail/ipxe-dev...05305.html

The post with links to multiple patches: http://forum.ipxe.org/showthread.php?tid...2#pid13392

Hi NikiZe, do you know if/when the iBFT patches are going to be merged?

If not then I'll see if I can build this myself. I've managed to build iPXE in the past but I'm not a developer so I don't know how to merge patches. Would you be able to give me some pointers?

Thanks

All of the iBFT functionality for UEFI is now present in the master branch.

Thanks for taking care of the iBFT for UEFI iPXE! I managed to get past the Win10 OS installation roadblock related to iBFT, and made it through the first OS installation phase. After the first reboot, I attempted to boot from the iSCSI disk, and got a 0x7f22208e error. I tried both ipxe.efi and snponly.efi with the same result. Not sure what is meant by "Platform-generated error".

It's an external EFI API call from interface/efi/efi_block.c that is returning an error 0x0e (EFI_NOT_FOUND). There are multiple points that could plausibly be generating this error. You can try building with DEBUG=efi_block to get some additional debug output.

I then initiated a Windows 10 (version 1607) OS installation into a mounted iSCSI virtual disk, but ran into the dreaded "iSCSI deployment is disabled since no NICs referenced in the iBFT can be resolved to actual NT-visible devices." error message. I'm trying to figure out what I might have done wrong, or whether iPXE may have an issue with iBFT in EFI mode.
I would love to try the efi san boot.
Would be able kind enough to share the steps you did to efi boot sanboot to winPE.

Thank you
