The question very similar to this, but no the same :(
Description
- A second storage device (SSD) was installed instead of the optical drive
- There was a one really successful boot from it
- BIOS from time to time loses my SSD
The problem
- When Esc is pressed, the SSD can be selected as a drive to boot now, but not always
- When F2 is pressed, the SSD does not appear on the boot menu where you can save the boot order forever. But it is listed on "Advanced/SATA Configuration" BIOS topic.
- Some times the SSD can not be seen on both boot menus: The startup and the BIOS. In these moments, the bootable USB drive is not seen too.
So what can be wrong with that? OK, may be there is some problem with drive detection, but why second drive cannot be selected even when bios recognize it?
System
The notebook is an ASUS x551ca. The OS is Windows 10.
keep rebooting until you see it
option.
