I have been having some issues with my cd drives lately first off my computer didnt even see them there so i took my case off and made sure all the plugs were very tight and it found them... Now i want to reformat and when i try to boot my computer from my windows cd it doesnt even give me an option to boot from cd...

*I have been able to reformat until the drive incident happened*

1.Reformat. Use the XP CD to break it into 2 partitions. Make one 15-30 gig for your operating system, the rest for your data (gamers need to make a 3rd 10-20 gig partition for your games). You can move my document to the 2nd partition. Go to start right click my documents, click properties (you can only do it here) and select move. Move it to you second partition. This will speed up disc performance plus if you have to reformat, you won't lose your data. Download all new things to the first drive and after a few weeks and you are sure they contain no virus or Trojan horses, then move them to the 2nd drive


I need & want to do that + i cant get programs to work...

steam is a big one i have tried reinstalling and installing to different folders and i still get the same error...

ALL I NEED TO DO IS REFORMAT

The reason i just cant reformat is becuase it asks me for a cd key O_O heh and i dont have the one that this cd is suppost to recognize...
