Solution Use Boot Device Disable The Phoenix BIOS being used in some systems, primarily Vostro and XPS, has an option called “Boot Device Disable” that will remove options from the Boot Device Menu that is accessed by pressing F12 on the Dell screen. After enabling this setting, the only options the user should have to boot to are the hard drive and the diagnostics. To enable the Boot Disable feature, the customer must enter the BIOs, then go the Advanced tab. On the Advanced tab, choose Miscellaneous Devices and press enter. Under Miscellaneous devices, the option for Boot Disable must be enabled. After saving settings, the options on the F12 boot menu should be reduced.
