Sometimes?!?!?!? Are you answering some test question or what? It's impossible that you "sometimes" get all these 3 different error messages.

Hey black2, Check [url=http://forum.raymond.cc/t1581-Weird%2C-Cant-boot-without-player..html]this.

simply repair your PC with Windwos Xp CD. Boot from Windows CD and follow the steps on the screen. thats should help you to solve all the three problems if you have them in a single PC at a same time.

To Raymond: 2 days ago, at the same day when i wanted to on my computer, first i got this

===========================================================
A Disk Read Error Occured
Press CTRL+ALT+DEL to restart".
===========================================================

well then i went to change some setting in BIOS, i press F10 to saved and exit, after i got this damn error:

============================================================
Error loading the operating system.
Press CTRL+ALT+DEL to restart
============================================================

I was so angry, turn off the power point wait for few minutes...and turn on again but still got the same problem "Error loading the operating system", then i ask myself did i set up the wrong setting(BIOS)?.
I Press CTRL+ALT+DEL to restart and then to bring up the blue screen (BIOS) to load the default setting, hit F10, saved and exit. Waiting for boot then i got another ERRRRRRORRRR:
============================================================
NTLDR is missing.
Press CTRL+ALT+DEL to restart
============================================================

This 3 error just making me waste a lot of time trying to solve it... anyone know what is "NTLDR"?


and also


To blackrose: "simply repair your PC with Windows Xp CD. Boot from Windows CD and follow the steps on the screen."
lol, i did but there dont have a step for me to repair the windows by "PRESSING R", just got a option to press D to delete partition, C to create partition and last one F3 TO EXIT THE WINDOW.

Well at last i formatted my HDD to installed a fresh operating system.
Even formatting the HDD, sometime i will get those error again but mostly with "A Disk Read Error Occured and sth like cannot boot from the hard disk". if i got a error that cannot boot from the hard disk, inserting the window xp cd will be useless becuz it cannot detect the hard disk in the setup window but in BIOS it detected..

I post'd this error becuz i wanted to know what causes this error, thats it
