One of the biggest strengths of using a Mac is that you can access all data from all startup disks while you boot one of them.
That is also its demerit.
Mac starts from its internal disk by default, and you will get no entry to access your data once it won’t’ boot from the internal disk.
On a Mac with Apple silicon: Press and hold the power button until you see “Loading startup options.” If you’re using a Mac Mini, wait for the system indicator light to turn amber. When you see the available startup disks, select one, then click the Up arrow (on Mac) or Continue button (on Mac with Apple silicon.).
- To pick a disk to start your Mac from while it’s booting, follow these simple steps for using macOS’ built-in feature called Startup Manager, which can be invoked via a simple keystroke. Step 1: Turn on your Mac by pressing the power button, or restart it if it’s already on by choosing Restart in the Apple menu.
- From within Windows, press and hold the Shift key and click the “Restart” option in the Start menu or on the sign-in screen. Your PC will restart into the boot options menu. Select the “Use a device” option on this screen and you can choose a device you want to boot from, such as a USB drive, DVD, or network boot.
The solution to it is that you can boot Mac from an external hard drive.
Booting Mac from an external drive, e.g. USB drive, enables you to access all the content of your internal drive.
Moreover, the Mac computer can recognize compatible bootable contents from a startup disk. In other words, it is sure to install a Windows 10, Linux, a beta upgrade Mac OS version, etc., on a MacBook Air/Pro, iMac (Pro), Mac Pro/mini, etc.
