We have a PXE server we attach to and after pressing F 12 to get to the PXE sever I see a Boot manager at the top of the list and this was never there before. I would then scroll down to select lan to grab the image to re-image the drive. Now the image that came with this is windows 8. Our image is windows 7. I changed the boot order and still get the error. No other laptop does this. I am concerened it is hardware? Does windows 7 need the boot manager at the top of the boot order? This is a brand new laptop from Lenovo? T 530.
