    I have primarily use a Dell Studio 1558 laptop. I recently had a hard drive failure. Luckily I cloned my entire hard drive to an external hard drive using Macrium Reflect. I tried changing the boot order in the BIOS so that my laptop would boot from a USB device, but this doesn't work. I also tried using bootsect to make my external hard drive bootable but to no avail. Can anyone give me any help with getting my laptop to run off the external hard drive? The laptop in question no longer boots at all, it crash dumps every time I try to turn it on and boot from the internal hard drive and it crashes when it automatically takes itself into Startup Repair.

    Just thought I'd add what I tried to do with bootsect:

    Put bootsect.exe into windows\System32

    "Open cmd

    bcdboot c:\windows /s c:

    bootsect /nt60 c: /mbr


    sel vol c


    But the cmd said "bootsect is not recognised as an internal or external command, operable program or batch file"

    The BIOS in Dell laptop's doesn't usually give you a lot of options so it might not be possible to boot from USB. Presumably you'll be looking to replace the internal hard drive with a working one? If so, you could use a different system to clone the content of your external hard drive to the new internal one and then plug it into your Dell.
