Thank you Joe! I had to switch back in SATA settings from "AHCI" to
"Raid ON" again to restore Windows boot.

First, does the laptop have a UEFI menu available on a hotkey during
startup? You may need to do a bit of Net searching to find it. If so,
there will be a Windows entry, try it.
The UEFI firmware, what we used to call the BIOS, may have options for
enabling and disabling drives and setting the start priority. See if
any fiddling with these options will help.
Windows will not boot normally now, but it may be possible to boot it
into Safe Mode with a hotkey. If so, there ought to be a way of
restoring booting.
If Windows can be started, it will have a boot fixing option, again
search for details on the Net. Once you have Windows booting reliably,
it should be possible to get grub working again. In the worst case, you
can download the (huge) Windows installation image for your version, and
use its rescue facilities to fix booting.
I'd be more specific, but I haven't needed to deal with Windows fixing
for a while. and never on 11.
