Microsoft addressed a claim that Windows 8 will not allow Linux operating systems to coexist in a dual-boot configuration on PCs.

Well, the first and certainly the simplest if it works properly, is to install the Linux GRUB bootloader as the default boot object, and have it control dual-booting with Windows.

I've been trying to set up multi-booting with Windows 8 and Linux - with limited success. Here's what I've learned so far.

If your Use original boot configuration option is greyed out in Windows 11/10 System Configuration MSConfig utility, then fix the problem by following this method.

Windows Vista through Windows 8 use boot configuration data, or BCD, to manage the boot process on a PC and control which options appear in Windows Boot Manager.

If while upgrading Windows to a newer version, you receive Windows could not update the computer's boot configuration, Installation cannot proceed error, see this fix.
