My Dell Latitude 7275 2-in-1 was delivered an hour ago. My plan was to boot to an Xubuntu 21.10 live USB to figure out if it would even work and, if it does work, then install it, wiping out the Windows 10 already installed.
I have the Xubuntu USB plugged in, but the laptop just boots directly to Windows. According to Dell Support for the Latitude 7275: https://www.dell.com/support/kbdoc/en-us/000131221/how-to-boot-to-an-external-device-using-usb-type-c-connection Please enable below two options to support boot from external device. At boot, Press the F2 key (or alternately press the F12 key then select the option to enter the BIOS setup). In POST Behavior, Select - Fastboot the select the Thorough option (Figure 1): I tried tapping F2 repeatedly after pressing the power button, but it has no effect - it still goes straight into Windows. I also tried holding F2 down continuously, but it still boots directly to Windows. And I did the same using F12, with no success. Does anyone know the secret way to boot to the BIOS?
