You will need to use a solution which emulates another computer on your computer – essentially, a virtual machine. The most obvious ones which come to mind instantly are VirtualBox and VMware, but those weren’t designed with debugging the machine and/or the OS.
What you’re looking for is either Bochs or QEMU. Both (as far as I remember) can be integrated with gdb in order to set breakpoints and analyze the execution of your code. You might also want to read this OSdev.org article.
