Repair boot.ini with a network boot

I changed my boot.ini file by accident yesterday and soon realised I had a big problem.. The booting process didn’t find my Windows installation any longer. The normal reflex would be to grab a boot disk and fix the problem in DOS. I couldn’t do this because my laptop does not have a floppy drive station. Well, no problem you say, just insert some Windows installation CD and boot from that CD. You guessed it, my CD-station on my laptop is broken for a few months now, so I didn’t have a means to boot my laptop. Another option would be to boot from a usb device, but my BIOS doesn’t support this. On the other hand, my BIOS DOES support a network boot (PXE). In this article I will briefly cover the steps I took to repair my laptop.
