There’s Dell Vostro 15 3000.

Can’t reach boot or bios.

If just turn on laptop - have only Dell logo and nothing more.

If I press F2 - have “Preparing to enter BIOS Setup” top right corner and progress bar (~30%).

If I press F12 - have “Preparing one-time boot menu” top right corner and same progress bar.

How can I resolve this issue?
