Inspiron 5490 Service Manual
Boot Sequence
Boot Sequence allows you to bypass the System Setup–defined boot device order and boot directly to a specific device (for example: optical drive or hard drive). During the Power-on Self Test (POST), when the Dell logo appears, you can:
- Access System Setup by pressing F2 key
- Bring up the one-time boot menu by pressing F12 key
The one-time boot menu displays the devices that you can boot from including the diagnostic option. The boot menu options are:
- Removable Drive (if available)
- STXXXX Drive (if available)
NOTE XXX denotes the SATA drive number.
- Optical Drive (if available)
- SATA Hard Drive (if available)
- Diagnostics
The boot sequence screen also displays the option to access the System Setup screen.
