I have an NT 4.0 server running mirror software between two identical drives. drive one have 3 partitions, non dos, C and, d Drive number 2 have two partitions c and d
Drive number one is not working
I could boot from drive number 2 using a boot dist to point to the second drive
but even after I modify the boot.ini to point to the secondrive it can not boot and it display the following error.
CAN NOT FIND NTLDR
the ntldr file is on the second drive
the boot.ini is pointing to the second drive
Its this because the non dos partition?
Its there is a way around this so I do not need to use a disk to boot the server?

thanks for your help

Your problem sounds like its one of two things. Either 1) you're missing boot files on that hard drive or 2) the BIOS isn't looking at the right drive to boot.

Have you removed the original drive that crashed? It could still be trying to boot there. Change the boot order in the BIOS or pop the cover and change the second drive from slave to master (if IDE). Make sure NTLDR, BOOT.INI, NTDETECT.COM, and NTBOOTDD.SYS (If its a SCSI drive) are on the hard drive.

That should do it... good luck

You need to set the partition on the mirred drive as active, once you've removed the primary drive. I recommend using a bootable floppy disk to boot Windows NT from the mirrored drive.
See the MS KB Article "Creating a Boot Disk for an NTFS or FATPartition [Q119467]"
