I'm trying to boot pxelinux from a hyper-v generation 2 (efi 64), but I keep getting NBP Filename bootx64.efi NBP Filesize 0 bytes and of course it doesn't boot from the startup screen The thing is the tftpserver works fine with pxelinux.0 and bios mode, and I can use a unix tftp client to download bootx64.efi without any issues. http://www.syslinux.org/archives/2014-March/021825.html I have my DHCP server set up just like steven from CloneZilla.org does. Any suggestions for this one? Luke Ledgerd / Internal IT Add: 156 Xa Dan II, 14th Floor, ?????????Dong Da District, Hanoi, Vietnam.
