[SOLVED] Is windows installed?

[AngelKaner]

Hello,

Unpacking a new computer stored for more than 5 years it shows the message:

Please enter setup to recover BIOS setting.
After setting up Intel(R) Optane Memory or the RAID configuration was built, SATA mode selection must be changed to RAID mode to avoid unknown issues.
Press F1 to Run SETUP

Apparently it seems that some bios parameters have been missed due to low battery
Entering the bios and exiting without saving the pc starts but only the ubuntu operating system appears, and this computer is supposed to be a dual boot windows 10 + ubuntu

Is it possible that some bios configuration that allows mounting the other windows 10 partition has been lost?

Your Ubuntu test says "Windows volume is dirty". Make Windows 7 / 10 installation USB / DVD, boot it, get to command prompt, and "chkdsk C: /f", then repair boot files. If you're lucky, you might be back in business.

And of course, you have to take care of that CMOS battery.

Finally I fixed it using grub customizer, hope it helps someone
