Every time I do a system upgrade my windows 10 gets removed because the drive it is using is a nvme using Intel RST. For now whenever it boots straight into manjaro I need to go into the bios change the drive mode and update grub to get it to show up in the menu, is there a way to add the location permanently with the output I get from os-prober?
In theory if you have OS Prober enabled for Grub, it should detect and add the windows entry automatically.
But every system is different and some things work differently depending on the system.
Provide maybe your Grub config file /etc/default/grub and how your systems are setup. How to provide good information
Where? How?
I will provide the grub when i run the update-grub with AHCI mode and with RST mode

As for why OS prober is not working I switch the drive mode to RST because my Linux can not mess with windows and because the auto fan control on windows seems to run quieter in that mode. The system upgrades are from pamac so every time I see it in the package manager I know I need to redo this process.
There is no difference between your two configs
You can add custom entries in /etc/grub.d/40_custom
Now /boot/grub/grub.cfg contains the current available entries.
You should be able to just copy the “menuentry” for win10 from that file and paste it into the 40_custom one…

Probably you need to load vmd (Intel Volume Management Device Driver), so that grub can discover the partition?
If using 40_custom:
Change in /etc/default/grub
GRUB_TIMEOUT_STYLE=menu
to get Windoofs-entry visable…
Do i copy from ### BEGIN to ### END into the 40_custom? When I do this I will change what GaVenga said to get it to show up.
I don’t want Linux to be able to see my windows drive and I read online how Linux won’t work in RST mode and how would you even install that on Linux?
Example
### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'Windows 10 Bootmanager' --class windows --class os $menuentry_id_option 'osprober-efi-xxxx-xxxx' {
savedefault
insmod part_gpt
insmod fat
set root='hd0,gpt2'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt2 --hint-efi=hd0,gpt2 --hint-baremetal=ahci0,gpt2 xxxx-xxxx
else
search --no-floppy --fs-uuid --set=root xxxx-xxxx
fi
chainloader /efi/Microsoft/Boot/bootmgfw.efi
}
set timeout_style=menu
if [ "${timeout}" = 0 ]; then
set timeout=10
fi
### END /etc/grub.d/30_os-prober ###
could be done with /etc/fstab - but keep a backup of the original file.
in Gnome ==> Gnome disk utility can be used as DE proggy.
(That´s safer).
I followed the example and it worked! Is there any way to change the order of the grub because windows is appearing after the uefi settings? I would like the order to be Windows, Manjaro, advanced options for manjaro, uefi so would this be possible?
Edit: Is it also possible to add an icon for the advanced and uefi? I think it would make my grub look better without using that grub-customizer thing because I heard it is not compatible with manjaro
