NTLDR is missing, why does it happen?
[[This problem may occur if the basic input/output system (BIOS) on your
computer is outdated, or if one or more of the following Windows boot
files are missing or damaged:
Ntldr
Ntdetect.com
Boot.ini ]]
http://support.microsoft.com/?kbid18728
[[Cause:
Computer is booting from a non-bootable source.
Computer hard disk drive is not properly setup in BIOS.
Corrupt NTLDR and/or NTDETECT.COM file.
Misconfiguration with the boot.ini file.
Attempting to upgrade from a Windows 95, 98, or ME computer that is using
FAT32.
New hard disk drive being added.
Corrupt boot sector / master boot record.
Seriously corrupted version of Windows 2000 or Windows XP.
Loose or Faulty IDE/EIDE hard disk drive cable. ]]

[[For this problem to occur, all the following conditions must be true:
• The system/startup partition is formatted with the FAT32 file system.
• The computer starts by using INT-13 extensions. (This is a partition
larger than 7.8 GB with a System-ID type of 0C in the partition table).
• Because of the cloning procedure, the Heads (sides) value in the
FAT32 BIOS Parameter Block (BPB) does not match the geometry of the
physical drive. ]]

Greetings, Hope I can get an answer here. New machine, I'll post the
specs if needed. a week or so ago, I get a message that something has
changed and I need to re-resister {nothing in the computer has changed.
nothing added, nothing removed. } so I do, and have to call in for hte
activation code, {what a pain}. Fine so now I am registered again. next
thing it does is on next boot it tells me that the NTLDR is missing,
Crap ok I go to the recovery console and re-do the boto sector. boots
fine. Then I take out the OEM CD and get the ntldr message again. I
then put the CD back in and try to boot up, and it boots fine. IT will
only boot if the CD is in the damned drive. Any ideas as to what may
have happened? or what I can do to fix this issue?
Thank in advance
