Hello,
I have a pxe server with gpxelinux. It can boot iso's over the network. I use WinPE with Imagex to deploy windows. I boot an WinPE iso over http and then it starts to deploy.
Some computers with Windows 8 have an uefi bios. The product key is stored in the bios. The problem is that Windows 8 only can get the key if it uses the gpt filesystem. To make the gpt partitions and the bcdedit settings, you must boot WinPE in uefi.
There's no option in gpxelinux to boot the iso in uefi. How can i solve this problem?
