Cannot Boot Windows NT After Running OS/2

ID: q101964

The information in this article applies to:

Microsoft Windows NT operating system version 3.1
Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

You may not be able to boot Windows NT from an HPFS partition after running OS/2.

CAUSE

OS/2 clears the flags field for the root directory Fnode, causing Windows NT to be more strict about allocation structures and mark the root directory as corrupt. This prevents your machine from booting from the HPFS partition.

WORKAROUND

To work around this problem, boot from the NTFS or FAT partition. After you boot Windows NT, CHKDSK can correct the root directory Fnode flags.
