grub2 - 关于Linux和Windows双系统启动项的问题

Answer 1

Enter Ubuntu and executesudo update-grub to automatically search for the system installed on the hard disk and add it to the /boot/grub/grub.cfg file. You will see the Windows startup items in the GRUB menu next time you boot.

Answer 2

I am currently using fedora+win7 dual system and have gone through these stages;
I used grub at first. Generally speaking, GRUB can recognize the win boot item. If it cannot recognize it, then manually add the WIN7 boot item. to GRUB or GRUB2 (current desktop Linux distributions are basically GRUB2);

But in this case, it will be troublesome when reinstalling WIN or reinstalling Linux;

The ultimate dual-system solution:
Add a hard drive; yes, add another hard drive; install WINDOWS on one and Linux on the other;
It is convenient to add a hard drive to a desktop computer, but it is better to remove the optical drive and add a hard drive to a notebook. It would be better if it has an M.2 interface ;
In this way, the two systems do not involve who includes whom, who depends on whom, etc., and are completely independent;
Just use the BIOS boot to boot. Manually add the disk where the commonly used system is located to the front of the boot entry, and you need to start the other system. When there is a hard disk, just press the shortcut startup key to select which disk to start;

It is necessary to increase hard drive investment. A 128GB solid state is not expensive, so you can consider it;
