I have formatted and copied windows 7 to my 4GB USB key and I have installed a new HDD into my Dell Optiplex 745. When I boot up the computer I am notified with:
PXE-E61: Media test failure, check cable
PXE-M0F: Existing Broadcom PXE ROM
I have searched and found out that this can be caused by a bad hdd but this can't be the case seeing that I literally opened it new from it's packaging and instantly installed it. Also I heard that in order to install via USB you need to place USB to #1 in boot sequence. I have tried this but when I do this all I get is a screen with a flashing underscore at the top of the screen and I can't do anything. So I changed my boot sequence back to the way it was:
1. Onboard or USB Floppy Drive (not present)
2. Onboard or USB CD-ROM Drive
3. Onboard SATA Hard Drive
4. Onboard Network Controller
5. USB Device
I have no backup disk and I have no access to a Windows 7 DVD, all I have is it on USB.
Any help would be greatly appreciated.
