No boot to operating system (no read-write error)
Use this information to troubleshoot issues with booting to the operating system.
Table 7-47 Issues, possible causes, and xes
Items Procedures
Symptoms
● POST error message: Boot Device
not found (3F0)
● Hang when booting to operating
system
Possible causes
Operating system, loose connection, faulty hard drive, BIOS conguration, Secure Boot.
Troubleshooting steps
1. Verify whether Secure Boot is enabled in BIOS. Secure Boot prevents legacy boot
devices from starting the computer, including bootable CDs and DVDs. For more
information, see http://support.hp.com/us-en/document/c03653226.
2. Reset BIOS to default. Be sure that BIOS Boot Mode in Boot Option is set up properly for
bootable device and its operating system (for example, UEFI Native for Windows 8).
Another example, choosing Legacy Boot Order for an UEFI device causes "Boot Device
not found (3F0)" error.
3. Verify hard drive connection and ex cable. Reseat connection. For multiple storage
devices, keep the primary drive with the operating system and remove other devices.
4. Use PC Hardware Diagnostics tool to test. Record failure code and have the hard drive
replaced.
5. If there is no error, reinstall the operating system using HP Restore.
6. Test with a veried working operating system hard drive, if available.
Note If there is a hard drive POST error message, see POST error messages and user actions on
page 127.
