Boot from MSDOS floppy and do "fdisk /mbr". That will re-write the master boot record. However, I don't think that is your problem. The problem is that the partition boot block (which is loaded by the MBR) can't find ntloader.
If your system disk (which is the disk you boot from - as opposed to your boot disk, which is where your operating system resides - sheesh!) is FAT, this means that ntloader is gone or corrupt. If your system disk is NTFS, this may mean that ntloader has "moved". Since the boot block code can't read an NTFS file system, it depends on a parameter table that contains the apparent cylinder/head/sector of where ntloader resides. The NT installer pokes the C/H/S address into the parameter table when NT installs. A common cause of this is trying to boot off of an NT mirror of the C: disk where the mirror does not have the exact same apparent geometry as the original. The NT4 resource kit goes into great detail about this. Whip out the NT setup CDROM and go through the repair process. If the server is important, pay Microsoft support to walk you through the process. Alternatively, try re-installing NT to an alternate location (say C:\WINNT2) and see if it fixes up ntloader. -----Original Message----- From: BW Brandt Ward (5320) [mailto:[EMAIL PROTECTED]] Sent: Wednesday, June 05, 2002 4:07 PM To: Exchange Discussions Subject: OT: MBR Recovery? My exchange server's boot record is toast...only boots with floppy...without..give the missing or bad ntloader message... anyone have any luck copying the backup boot record over the corrupt one? If so, using diskedit or something else?
