My SSD drive on an HP desktop with UEFI firmware [Nov 2016] is loaded with dual boot of Xubuntu and Windows 10, but when Windows 10 shuts down and is booted again, it boots directly to Windows 10 without showing the dual boot options. After I disable the Fast Startup option in Control Panel, the issue keeps occurring, then I use boot-repair and the dual boot option shows up again; however, after using Windows 10, the same issue begins again.
I use a USB stick with Xubuntu to boot the PC, then install boot-repair from the internet, however, since I meet this issue so often, I decided to make a live-USB disk of Boot-Repair-Disk, and the bad problem happens after I use the Boot-Repair-Disk to boot the PC to fix the missing dual-boot issue:
- it first reports some errors of the UEFI firmware, then reports no SSD found
- if I try to reboot the PC with the USB stick of Xubuntu to run boot-repair, it reports the same errors
How can I access the SSD again to see what happens and/or what else should I try (I hope to find some kind of low-level USB scanning tools for detecting the SSD first)?
