I got in a new Latitude 7450 for testing.
I was trying to get it work with UEFI. I was able to get it to PXE boot by turning on "enable UEFI network stack" but in PXE the C/D drives etc weren't available and Ghost failed out.
I went back into BIOS and into SATA operation and switched it from RAID to AHCI. Now in PXE the machine sees the C/D drive and my win7 image copies down.
Great. But not really. Now the machine won't boot. I get the dell black splash screen. If I hit F2 to go into BIOS, I get Preparing to Enter Setup forever. F12 doesn't do anything either. It just sits there.
I tried taking out CMOS battery and RAM but still seems hosed.
I found this somewhat similar thread over at Dell. I removed the hard drive but still can't get into BIOS.
Secure boot was on in the BIOS if that matters and reading this other Dell article says UEFI/Secure boot should all be off for win7 - but I never saw a machine I couldn't get back into BIOS to make necessary changes.
Anyone have any ideas?
