Boot disk failure

I have got several boot disc failures lately and my computer shuts down and it says "insert the boot disc" but I just restart my computer because it boots from the ATAPI cd rom.

then it starts checking the disc after I restart and it says 960kb in 29 folders,
windows has fixed the disc.

then it says do you want to convert lost chains to files {Y/N} Am I suppose to click yes or no? I always say yes because I am not sure about which is right.

then after it does
that I get a new entry in my system startup
it s called "Kernel/Fault Check %system root%\system 32\dump prep 0 -k "

should I leave that to start up everytime I start my computer or can I uncheck it to keep it from starting up the next time?
thanks

I hope you mean 960 megabytes instead of 960 kilobytes. In any case, you are getting the boot disk errors because your hard drive is dying.

Go ahead and select No.

That is normal for XP to do that when a system problem is detected, and it doesn't have to be there. But then again, what's the point, your computer is just about ready to quit booting up at all. Sooner or later the lost chains are going to be system files. Converting them to files will do you no good, unless you happen to know which ones are disappearing, and know how to assemble them (think Humpty Dumpty and all the king's men and horses).
Now is the time to get another drive, before all your files are lost. With a new drive with XP installed, you can transfer your files, or burn them to a CD now.
