I have windows XP installed and I'm sure that it is a clean and perfectly working installation. The problem I am facing is that my computer while booting, after Verifying DMI pool data, it boots from the CD-ROM and then a problem comes which says "DISK BOOT FAILURE - INSERT SYSTEM DISK AND PRESS ENTER". Why does this problem come even when I have the windows installed? The jumper settings and device priority settings (primary master, primary slave) are all fine. I check them. My HDD is on Primary Master. Before I used to get the NTLDR Missing error which I fixed using the "fixmbr" command in the recovery console. Now this problem came, and I am not able to fix it. Anyway I can fix this problem? What do you people think the cause of this problem is? is it the HDD? or my motherboard? or somethign else? And yes, I do sometimes get the CMOS Cheksum defaults loaded error. I just press F1 and continue. Can it be because of this also?
Please help me out. Its urgent.
