DOCUMENT:Q168502 09-AUG-2001 [winnt] TITLE :Windows NT Reboots Continuously During Installation PRODUCT :Microsoft Windows NT PROD/VER:3.5 3.51 4.0 OPER/SYS: KEYWORDS:kbsetup ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0 - Microsoft Windows NT Server versions 3.5, 3.51, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When you are installing Windows NT Server or Workstation, your computer may reboot continuously after the first reboot. CAUSE ===== This behavior can occur if the Bootsect.dat file in the root of the hard disk is infected with a boot-sector virus. The Bootsect.dat file is an image of the boot sector with added code to load Setupldr.bin to continue the Windows NT installation. RESOLUTION ========== Boot the computer from a virus-free bootable floppy disk. Use a third- party virus detector (such as McAfee's Virus Scan) to scan the root of the drive. Clean the virus from the Bootsect.dat file. If the file cannot be cleansed, boot from a write-protected bootable MS-DOS disk and use the SYS C: command to place a new boot sector on the boot drive. Run Setup again to create a new Bootsect.dat file, or reformat the drive and reinstall Windows NT.
