You're looking into setting up a bare-metal Linux installation with specific goals. First, installing Linux directly will overwrite the WBM and require using Windows via GRUB as a bridge. To let users pick the OS at boot from BIOS while keeping WBM as the default, you'd need a custom setup or a bootloader that supports multiple OS options. For isolating your Linux installation, you can partition the drive so only the Linux filesystem is accessible, preventing access to other partitions—this helps protect your system if something goes wrong.
Linux needs grub to start. Windows boot menu doesn’t let you select Linux as the OS. It’s better to use grub to decide which operating system loads. Be aware that updates might change this behavior. If needed, use a Linux live CD to fix grub issues. In Linux, you can set fstab rules so drives aren’t automatically mounted. Or remove the ntfs-3g package to stop Linux from reading fat/ntfs filesystems.
You're setting up Linux on dual-boot systems with a dedicated SSD for each OS. The boot manager is placed there, keeping Windows separate and avoiding conflicts. Adjusting the boot order in GRUB lets you pick the desired operating system automatically. For Windows, you can set it as the default despite personal reservations. I usually pick a 3-second selection time to keep boot times efficient.
They need WBM and grub to appear as separate choices during BIOS startup. Adjusting their sequence keeps Windows as the default while still allowing manual Grub booting.
Install Linux using GRUB, since it's needed to boot from BIOS. This may cause Windows to boot for a short time. To fix the issue, either restart into Windows installer to repair the bootloader or switch to Linux and run efiboogmgr to make Windows boot manager higher priority than GRUB (assuming both OSes were installed without CSM). Once done, you can boot from BIOS to Linux or press F8 at startup to access the boot menu.
You haven't specified your installation location for Linux. If it's on a different partition, you can set up Grub there without affecting your Windows drive. You can also configure BIOS to boot from Windows and then switch to Linux when needed. I still think this adds unnecessary complexity.
Update Grub settings in your Linux system if you're using a dual boot setup. During installation, you can choose Windows as the boot option at startup. Consider turning off Fast Boot and adjusting the timeout duration to allow enough time to access the Grub menu.
You don't want to start the system from scratch. You just need to pick the boot option for GRUB instead of launching it directly.
