- TITLE :Windows NT Boots, But Looks for Wrong Boot Directory
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- ----------------------------------------------------------------------
-
- SUMMARY
- =======
-
- Windows NT may boot successfully, but look for the wrong boot directory.
- One possible cause of this problem is installing over an earlier
- installation of Windows NT. The BOOT.INI file isn't correctly updated
- during the subsequent installation; certain releases marked the BOOT.INI
- read-only.
-
- Another cause might be an unsupported partitioning scheme, such as a
- MOST partition. When Windows NT encounters an unknown partition type,
- the numbering of logical partitions may be off by one.
-
- Installing Over a Prior Installation
- ------------------------------------
-
- If you are going to install over a previous installation, make sure that
- the BOOT.INI file is not read-only so that Setup can modify it.
-
- NOTE: Windows NT is not an upgrade. Installing Windows NT over a previous
- installation will erase any customizations you have made.
-
- If you installed over a previous installation, make sure that the BOOT.INI
- file contains references to the correct directory (for example, C:\WINNT
- rather than C:\NT).
-
- Installing With a Different Partitioning Scheme
- -----------------------------------------------
-
- If you have installed NT on a machine with a different partitioning
- scheme, try changing the boot partition specified in the BOOT.INI
- file.
-
- Settings for GUI Installation
- -----------------------------
-
- The GUI installation program creates a different BOOT.INI file,
- containing SCSI syntax. Before the SCSI syntax can be used, the
- appropriate miniport driver must be copied from C:\NT\SYSTEM\DRIVERS
- to C:\NTBOOTDD.SYS. (See below for a detailed explanation of the
- SCSI syntax and for descriptions of the miniport drivers.)
-
- Note: The GUI installation program copies the driver and changes these
- settings automatically.
-
- [multiboot]
- timeout = 30
- default = scsi(0)disk(0)rdisk(0)partition(1)\winnt
-
- [operating systems]
- scsi(0)disk(0)rdisk(0)partition(1)\winnt = "Windows NT" /NODEBUG
- c:\ = "MS-DOS"
-
- The SCSI syntax is as follows
-
- scsi(w)disk(x)rdisk(y)partition(z)\winnt
-
- where:
-
- - "w" is the SCSI controller number; numbering starts at 0 (only
- one SCSI controller number is supported at this time).
-
- - "x" is the SCSI ID number, 0 to 7. Some controllers reserve IDs 0
- and 1 for BIOS support for hard drives and ID 2 for a CD-ROM drive.
- This is not a requirement for Windows NT.
-
- - "y" is the SCSI Logical Unit number (up to 255 units are
- supported).
-
- - "z" is the partition (0 would specify the whole logical unit).
-
- The following are some of the common miniport drivers included:
