Hello Everyone!
i recently bought a acer nitro 5,and i came to know that i have to change the SATA mode to AHCI to install linux.
But without installing any linux , I simply changed the SATA mode to AHCI and tried to boot into WINDOWS.
But it didn't boot
I showed inaccessible boot drive
What Should i do??

    Change it back to RST in BIOS and then boot to win and follow this instructions. https://support.thinkcritical.com/kb/articles/switch-windows-10-from-raid-ide-to-ahci

    You forgot to tell them the important part: In the BIOS, in the Advanced Tab, press ctrl+s to make the Sata mode setting appear. Then change it to AHCI. (Recent UEFI/Bios versions from Acer require ctrl+s to show Sata options now. I am on Aspire-a515-54. Bios v1.18)

    So instead it's:
    1. Click the Start Button and type msconfig to open System Configuration
    2. Go to the Boot tab.
    3. Check the box that says Safe Boot (minimal)
    4. Hit OK and Restart the computer. Enter UEFI/BIOS Setup by pressing F2 during the ACER screen after power on.
    5. Go to the Advanced tab.
    6. Press Ctrl+s (If your model already shows the SATA options skip this.) You should now see the Sata Mode setting.
    7. Change the SATA Operation mode to AHCI from either RAID or Optane.
    8. Save changes and exit Setup and Windows will automatically boot to Safe Mode. Safe Mode clears the Raid/Optane driver so Windows will autodetect the new AHCI disk on reboot.
    9. Type msconfig in Start Menu once more and disable the check box next to Safe Boot. Select OK and Reboot.
    10. Windows will automatically start with AHCI drivers enabled.
    If you still get a Blue Screen error start the process over: Bios>>Raid-mode>>Reboot normally >> >> >> Msconfig (Safe Boot setting)>>Boot to Bios F2>>Ctrl+S>>AHCI mode>>Safemode (remove Safe Boot setting)>>Reboot.
