Hello all, i’m googling/reading a lot of thread from at least a week on this problem, just today i reg to this forum, only to say I have same issue with Acer P253M notebook.
I tried recover image (from Acer dvd disks) with win7 and win10, same issue, Bios boot type was set to “legacy” (not uefi) but the O.S. was set by Acer with GPT partition.
I fear this is the problem, the GPT Partition.
I’m going to try with an “MBR partition”… (microsoft call the partition schema in this clear wrong way)…

But after all i would ask: what kind of boot pxe-fog-booting-img use?!
It’s Syslinux?
May be it’s there the problem, could a syslinux update (or downgrade) to solve the problem?

I found this workaround for an old version of Fog in wiki:
https://wiki.fogproject.org/wiki//index.php?title=Boot_looping_and_Chainloading
and other site
http://community.spiceworks.com/how_to/108551-fog-boot-looping-and-chainloading

But i can’t apply this method just because i can’t find /tftpboot/pxelinux.cfg/default
i’m going off road…?

Thank you.
