Have a "pxe-e61: media test failure, check cable" error on a toshiba satelitte L455-S5975, Windows 7 Had to replace hard drive because orginal failed. Changed BIOS to boot CD/DVD drive first, then hard drive second, to load Windows. When I started laptop I received "pxe-e61: media test failure, check cable" error. I changed BIOS to load the hard drive 1st, CD/DVD 2nd. same issue. - BIOS does identify both HDD & CD/DVD drives. - CD/DVD drive was working correctly right before the old HDD failed. What else can I do? Thanks.
