    grub menu not showing in dual boot

    i installed my ubuntu on ahci mode and my windows pre-installed on Raid-On mode. it worked fine for a month and then one day when i changed to ahci mode in bios setup and tried getting into ubuntu the grub menu did not show up and it just kept restarting on dell loading screen and when i change to raid on mode again grub menu did not show up and boot straight into windows.
    i dont know what went wrong.

    Now i dont see my ubuntu in bios setup boot sequence also.

    after research i think its not detecting hard drive as in diagnostics it says hard drive not installed.

    windows working fine. what can i do?

    boot-repair detalis

    Script is not good about showing details on NVMe drives, but should show it in list of drives & UUIDs.
    Not seen anywhere?
    Usually Ubuntu will see RAID, but grub will not install or install correctly to RAID drives unless using Server installer.

    I know many users need UEFI updates & SSD firmware updates to have system worked. Not sure why if it worked before why now it stopped working.
