ACER BINSPIRE 1 D270 netbook...just fitted new HDD and attempted to boot from usb after changing setup boot order ,and got REALTTEK PIEe FE family controller series v1.27 PXE-E61 :media test failure ,check cable .......message ...does this mean the HDD conection is no good or what...as setup recognises a HDD and gives it's identity !!??  Halp please geeks many regards

Did you install a new operating system on the drive? You can't just boot from a new drive - you need an operating system on it, and a valid boot loader installed as well.

Thanks rubberman ... The pendrive has an Acer win 7 boot on it but the pc fails to recognise the pendrive due to the MEDIA TEST FAILURE,CHECK CABLE message
