My new Acer Nitro 7 (with preinstalled Windows 10) had SATA mode pointing to RST. During Ubuntu dual boot installation, I did the following (after browsing through website information on how to dual boot).
1) In windows, turned off fast boot option
2) Came to BIOS (which was version 1.05, then), in the main menu, a) Enabled F12 boot menu, b) Changed SATA mode to UHCI, kept the UEFI as it is, kept the Secure boot as it is.
3) Then I was able to install Ubuntu using bootable USB, and successfully installed and created users etc, and shut down
I thought we can switch SATA mode to RST premium with Optane, with a thought that, if it does not work, we can come back and change it to UHCI again. [This was the blunder I made, I guess. Frankly, I don't know what is RST/UHCI and all]. As I saved these changes and exited, I went to the Windows.]
I was just browsing with a thought that everything went well.
I noticed that there was a BIOS update version 1.09 available for this laptop. So why not install it? Thus, I went to Windows, and then installed BIOS update. When the BIOS update was getting finished, I got the grub menu, and I chose to go to Ubuntu to see if I was able to boot to the system, and I was able to get into Linux.
Then, I wanted to make the Windows boot option default. So I restarted the system to go to BIOS but then I noticed my SATA mode is no more there in the main menu.
Can anyone here help me understand how to get the SATA mode again in my main menu. (And if time permits, can you please explain what happened here. Why is the SATA mode is missing in the main menu.)
I hope I gave all the details. Please let me know if you want any other missing information that I left out here.
Other system info:
1 SSD of 256 GB + 1 TB HDD
4 GB dedicated Graphics
Intel I5
Acer Nitro 7
Thanks and Regards,
