Use rEFInd SSD+HDD to install win 10(SSD) and Ubuntu(HDD) dual systems.

I think so too. Installing win 10 on SSD is the main system after all. Install Ubuntu on HDD, and you can play by yourself.

Because it used to be a hard disk, it is very simple to install a dual system. Install win 10 first, and then install Ubuntu. Because I don't like Ubuntu's grub2 boot very much, the last installation boot was installed on /boot (uefi seems to be /EFI, I don't know much about it), so windows booted Ubuntu when I started up.

But it won't work if you install it on two hard disks. Restart win 10. I can't see Ubuntu. I've been looking for a way.

Boot two systems with rEFInd.

Mount ESP, put refind in, modify conf, bcdedit

If you are in a hurry to play games, write so much first!

First, find a way to throw rEFInd into the ESP partition of the system. First, mount the ESP partition. With the permission of the administrator, enter the command in cmd or powershell.

At this point, the ESP partition is mounted to x:, but it is still invisible in the Explorer, sometimes it seems to be visible, but it still cannot be operated. First, the cd is placed in the refind directory. use

But! Sometimes I can't, and I can't remember what it says. At this time, you can try DiskGenius and just throw it in. It's that simple.

Then rename the configuration file.

Then set refind to boot.

Restart the computer

There are probably so many procedures, but I still hope to prepare pe as much as possible before the operation, and it will be saved in case of problems ~

Unconfirmed things, there is an icon in the directory, probably resources. By modifying this, you should be able to change the appearance. Parameters in the configuration file refind.conf can add or delete startup entries. These things need to be searched later.
