4.6 Solving Booting Problems
A hardware or software malfunction can prevent the operating system from
booting when you enter the BOOT command.
Hardware Problems
A read error on a disk drive or console medium, or a machine check error, might
indicate a hardware malfunction. When a hardware problem occurs, a question
mark (?) usually precedes the error message that is displayed on the system
console terminal. You should then perform one or both of the following actions:
• Consult the hardware manual for your computer.
• Contact your Compaq support representative.
Software Problems
If the operating system is loaded into memory but the STARTUP.COM command
procedure does not execute, a software malfunction has probably occurred.
Suspect this condition if a message similar to following message does not appear:
The OpenVMS system is now executing the system startup procedure.
Perform one or both of the following actions to correct the situation:
• Try again, by repeating the boot procedure. For instructions, refer to one of
the following manuals:
– On VAX systems, refer to the most recent versions of the OpenVMS
VAX Upgrade and Installation Manual and the upgrade and installation
supplement for your VAX computer.
– On Alpha systems, refer to the most recent version of the OpenVMS
Alpha Upgrade and Installation Manual.
If you have a removable system disk, replace it with a backup copy of the
system disk. Try to boot the system again.
• Leave the system disk in the original drive. Restore a backup copy of the
system disk. For instructions, see Section 11.17. Try to boot the system
again.
