Changing the exit type to the GRUB loader fixed it, thanks again.

Updated BIOS was a no-go, going to try changing the exit type, thanks for the quick reply

So to explain we just upgraded from 0.3.2 yesterday to 1.2.0, and let me be clear, I love all the new features and updates. There is a small issue I wanted to raise and see if others have been having it, or if it’s a known issue, I did some quick scans of the problems threads and didn’t see anyone else with the issue. We have some older machines (Dell OPTI 970), probably only 6-7 clients, that are going to iPXE just fine when they start up in the morning, but when the 3 second timeout occurs and they attempt to boot from the hard drive, the screen freezes and the iPXE client locks up. Of course this is completely avoidable by forcing it to boot from the hard drive during bootup, but is there a log file on the client or something I can provide you with that will make it easier to diagnose why this is occuring? I wouldn’t think so because of the nature of iPXE running before the OS. These do have some older BIOS versions and I was going to attempt to update these to see if it’s as simple as updated iPXE client handling in newer versions. Will report back if this fixed the issue.
