Inaccessible Boot Device

I fired up my PC yesterday morning and was welcomed by the dreaded BSOD. It told me that it had run into a drag caused by an inaccessible boot device. There are numerous help sites online that specify the way to affect this issue. I attempted all of them bar one, and none of them got me up and running again. the sole one I have never tried is that the hard reset option. Although I even have backups of most of my files, I didn’t want to lose what’s on my disk drive unless it’s necessary. Reinstalling all the applications goes to be an enormous enough PITA. I’d have the interest to find out whether anyone else hit an equivalent brick wall and aroused wiping their disk drive because nothing else worked.

Having spent most of yesterday trying to resolve this problem and getting nowhere, I’m wrestling with the thought of ditching Windows altogether and switching to a Mac. Does anyone want to offer me an argument?

BTW I typed “Inaccessible Boot Device” into the search box on the BSOD forum and got zero results.
