Sorry to join the group and start with a problem! It all started a few weeks ago, my computer started to have problem to boot I used to receive a message "K BOOT FAILURE INSERT DISK AND PRESS ENTER", I had to turn the computer off and on and once every 20 or 30 attempts I was lucky to start Windows XP. I contacted HP and they asked me to disconnect the HD and reconnect it, did not work. HP suggested to try recovering Windows XP, but didn't work either. I assumed the problem was the hard drive, so I bought a new Seagate 200 GB and intalled it as master and the old as a slave, to do that I had the problem of booting it, I discovered that pressing F8 (safe mode) my computer started correctly. So installed the new disk, re-installed Windows XP, installed SP2 yesterday and today I have the same problem, but the message is different "DISK BOOT FAILURE, INSERT DISK AND PRESS ENTER". I have not been able to boot even with F8. While enetring BIOS it does not recognize the HD's, and yesteday while installing Windows XP it recognized both perferctly! Can somebody help me??????
