Jen's new PC went billy, bang, bollox over the weekend. After a game froze up she did a hard shut down and when the PC restarted it wouldn't load Windows and was stuck on the message: 'Loading PBR for descriptor 2...done'. After much head scratching and googling I found lots of things to try but nothing worked. It appeared as though this problem was unique to Dell and was connected to way their PCs are configured to boot up.

I went into the boot menu at startup [F12] and chose the Recovery option which gave me a command prompt. So I googled DOS commands and came up with 'BOOTCFG /DEFAULT', in a brave/foolhardy (delete as appropriate) move I tried this and it worked! I don't know how and now the PC boots up so much faster than it ever did.

If anyone knows DOS, what have I done? Are there likely to be any issues with what I've done? On the surface it looks to to be running so much better.

Thanks.
