Hi, product is HP 655 Notebook pc operating system windows 7 however due to my daughters negligence (dont know exactly what, do know she very rarely if ever shut it down properly) the computer would go on but but only to black screen stating after general info at top (PXE-E61: Media test failure, check cable) next line (PXE-MOF: Exiting PXE ROM), on last line (No bootable device -- insert boot disk and press any key). dint have the boot disc only the product key so downloaded windows 7 home premium, put it on disc to start again. While trying to install Win 7, I get past a couple of screens in (collecting information) then I get stuck at a "Select the driver to be installed." screen. there is nothing in the box to choose just a statement "No signed device drivers were found. Make sure that the installation media contains the correct drivers, and then click OK.". Im certainly no expert but can and have followed instruction just dont know if i'm missing something, any help in this matter would be very much appreciated and thank you in advance!
