After bios_grub is enabled, os-prober does not seem to be enabled

My computer equipment is relatively old, can only use BIOS boot mode. And I have two hard drives, one in MBR format, and I installed Windows 10 on that hard drive. The second is the GPT format. I originally wanted to use bios_grub to install Arch Linux on it, but when I finished following the official Arch Linux installation guide, I didn't see Windows10 in the boot option.

I ran the os-prober command, but it didn't produce any output. I also removed the GRUB_DISABLE_OS_PROBER=false comment, but after the restart, I still did not see the startup item of Windows10.I don't want to change my GPT hard drive to MBR because MBR only supports 4 primary partitions.

When I used the Manjaro system before, I used the Calamares installer to install the Manjaro system on my GPT format hard disk.

But for various reasons, I wanted to switch to Arch linux. I read a lot of articles, but I still can't display my Windows 10 startup entry..

I have tried to use this method to fix it before, but it doesn't seem to have any effect.

What, exactly, did you try from that link?

Uh., I seem to have discovered why it didn't work before. My previous system was installed from a PE environment, but it seems that no boot was provided during the installation process, causing os-prober to be unable to find it. A few days ago, I reinstalled the Windows 10 system. So it has a boot partition, and after mounting the boot partition, os-prober works normally.

Anyway, I sincerely thank you
