What happens if you change the boot order in bios to boot to the HDD containing windows?

It just boots up windows without the GRUB menu

It is very overwhelming for me... but thanks I will try to understand it

well its not much of surprise because they don't share a bootloader partition

This has nothing to do with the problem, grub can load an OS from any disk and partition (if it is a sensible one; it might not do something like booting a DOS-based OS from an extended partition etc.).

Post  the output of "sudo lsblk" and "sudo blkid" here, that way we can help.

 

The page can be daunting as it has loads of information out of which not all is relevant to you. To summarize the process is roughly:

1. install os-prober (it is not installed per default in Arch),
2. mount your windows partition and then
3. run grub-mkconfig (as outlined earlier on that page).

With the help of above commands, people can probably give you the exact command needed to enable grub detecting Windows.

 

(in case you ever re-run grub-mkconfig, you need to remount the Windows partition less grub-mkconfig will overwrite the configuration without Windows entries)

All you have to do is install os-prober:

 

sudo pacman -S os-prober

Then mount the Windows partitions, and run: 

 

sudo grub-mkconfig -o /boot/grub/grub.cfg

I can't mount those drives.. bcz it is NTFS
and it says unmounted and no option to mount it

You need to install ntfs-3g with

sudo pacman -S ntfs-3g

And are you sure you had them all successfully mounted when you ran grub-mkconfig? Because what you should get is something like this, note "Found Windows Boot Manager" on there:

ntfs-3g  is the first thing to make sure is installed. 

Garuda is Arch-based?  Devs were negligent, IMHO.

Update: I uninstalled the KDE version of Garuda and installed GNOME version of Garuda

now when I ran 
 

sudo pacman -S os-prober

 

I got this error

You already have os-prober, then. Garuda apparently uses a forked grub with a forked os-prober. 

 

Just out of curiosity, what's the output of

efibootmgr

?

Literally didn't understood the first line
but is there any fix for this?
or crying is the only last option?

[gardotd426]

Yeah something weird is going on. It looks like your Windows install isn't using UEFI. 

 

See:

 

[gardotd426]

I mean you only need one entry, mine has two for a different reason, but yeah efibootmgr should show all EFI bootloaders on the system (and doesn't use os-prober), and yours isn't showing Windows.

So I need to install Garuda Linux without UEFI?
am I right?

So If I install this OS without UEFI
it will work right?

[gardotd426]

No, you need to be using UEFI. Windows isn't using UEFI, and it needs to be. You would need to reinstall Windows and use UEFI. 

 

Or, you could install refind and use refind instead of grub as your bootloader, and see if that detects Windows. If it doesn't then you're definitely not using UEFI for Windows.
