Greetings,
I have an NT 4.0 server w/SP3 on an HP NetServer E50. It has an HP/Adaptec 2940UW SCSI card w/2 9.1 GB HD's attached.
The drives were mirrored and have a 750 MB FAT C: partition. The D: partiton uses the remainder of the drive and is NTFS.
Recently the drive with ID1 failed. I removed the drive, booted with an NT boot disk, got into NT without any problems, I then broke the mirror. At this point everything is working normally, except, I need to make the remaining drive bootable. I keep getting a message saying Boot: NTLDR not found, insert another disk.
I have checked the Boot.ini file and have check the existing drive for the existance of the NTLDR and NTDETECT.COM file and they are on the root of the exisiting drive.I changed the ID of the good drive to "0" but it didn't help. Nobody ever made a repair disk. What do I need to do to make it bootable? I am concerned that when I put the new replacement drive in and mirror it, it still won't be bootable.

Many thanks,
Brian

What has happened is that you do not have a master boot record, and your partition may (or may not) be set active.

You should be able to use your Repair disk and repair the boot sector...

It sounds like the drive with ID 1 was the primary boot device. You should change the SCSI ID on the remaining drive to ID 1 or change the boot.ini arc name to reflect the appropriate boot device. This will allow the remaining drive to boot without using a floppy.

If you look up above, you will see that I added some comments to my original post. ID0 was the drive that failed.

Coyp boot.ini, ntldr and ntdetect.com on a diskette. Edit the boot.ini file and change the disk id. Then you can boot from the second disk.

Should'nt the Boot.ini that's on the boot floppy I'm using now work if I just copy it to the existing HD? It obviously works and is pointing at the correct HD otherwise it wouldn't boot. Right? I tried that and it didn't work. I believe it's an issue with the MBR.

Boot to DOS and run FDISK. Make the partition where the boot files are active.

Use the SCSI utility (crt.A) to check the boot drive ID and set it as the ID of the drive you have.
