Sees the drive if that doesn't work then either disassemble and try to disconnect-connect the drive or boot from a flash drive, or carry in SC.
In Recovery mode perfectly sees the disk, erases it and puts it on the OS. During installation of the axis window "downloading components" disappear, but after reboot this. - ludwig commented on September 26th 19 at 06:17
Try in Recovery mode to force you to specify the desired boot volume. - Alec_Von commented on September 26th 19 at 06:20

Try at boot time to turn off the screen, there will be more information, what exactly is the problem.
