Hello . I put two new hard drives in the new computer, respectively, there was nothing on them. I made a bootable USB flash drive, but when I turn it on, the error immediately appears

There is not even an opportunity to enter Bios. Immediately when you turn it on, there is an error, the keys DEL, F1-F2, not one of them helped, only the key combination CTRL + ALT + DEL (Reboot) works. What can be done . Two hard drives connected at once, Gigabyte H81M-DS2 motherboard.

Answer 1

In general, none of the options helped. There really was no home screen. Only disconnecting both disks and inserting a bootable USB flash drive helped. Only after that the initial screen appeared and from there, by pressing the DEL key, I entered the BIOS (There was no initial screen with the connected disks, there was an error right away). After that, I set the priority to the USB flash drive, saved it, turned off the PC, connected both disks and turned it on after that, installed it safely.

Answer 2

Try ESC again. Sometimes entering the BIOS on it.
