I think I found this community forum a little too late but here are the details: A friend has an XP Pro installation on a 40GB Maxtor drive. The PC would try to boot and come up with the error message of: We apologize for the inconvenience, but windows did not start successfully and give me a choice to boot Normal, Safe, Safe with Command, and Safe with Network. It would try and boot, then automatically restart.. (Auto Restart must have been checked) I took the drive out of the PC and installed it on my XP PC (secondary IDE) The PC assigned a drive letter but when you click’d on the drive, it responds with: The disk is not formatted, do you wish to format it now? I then replaced it back into the original PC and attempted to do a Repair. Not the recovery console but Enter to install. At this point I couldn’t do a repair because the partition was listed as: Partition 1 (Unknown) I then fired up the Recovery Console. I issued a CHKDSK command and it responded with “The volume appears to contain one or more unrecoverable problems” Next I tried a DIR command and it responded with: "error occurred during directory enumeration At this point I didn’t know what File System was on the drive. Back at the Recovery Console, I tried a FixMBR I forgot to write the specifics but it didn’t change a thing and I was still able to get into reboot loop at startup. Here’s where it gets ugly. I then issued a FixBoot command, and it came back with: Fixboot is attempting to detect the file system type. The boot sector is corrupt Fixboot is checking the file system type The partition is using the FAT file system Fixboot is writing a new boot sector The new boot sector was successfully written Now when I try booting the PC, all I get is a “NTLDR is missing” message. The FixBoot util created a FAT boot partition of 10 MB as seen in Windows Explorer. I used a partition utility to look at the partition and it said it was a FAT12 partition which I thought was only used for floppies. Did I hose myself? I would bet the original partition is NTFS but now I only see a FAT partition. Then I found this community and this thread hit close to home: http://www.techspot.com/vb/all/windows/t-5352-cannot-boot-xp-ntfssys-blue-screen-0x00000024.html I think this would have worked for me had I not overwrote the partition boot sector. My friend really needs the data off the drive. Do you see any way get this back? Thanks for your time.
