Start pxe over ipv4 - boot issues

Peter, thanks for responding. The only reference I see to network booting is in the bootloader sequence options. Typically, in a legacy BIOS bootloader, you have your sequence of CD, USB, HDD... but with this new windows bootloader, I'm only seeing IPV4 and IPV 6.... the HDD isn't an option. I can disable secure boot, which would allow me to load legacy options, but it throws up a warning that disabling could render my HDD useless if Bitlocker has been engaged. I'm concerned that Windows 10 has automatically enabled Bitlocker (I thought I read that somewhere). So, I don't know what to do... I can't imagine my HDD is shot. I wish I had never signed on for these Insider builds, they've been nothing but headaches.... My Mac buddy doesn't have any issues with his early release beta builds coming from Apple...
