Windows 7: Which OS should I install first dual boot Win10/Win7

Which OS should I install first dual boot Win10/Win7

I'm planning to install Windows 7 and Windows 10 dual-boot on my laptop. I have deleted all partition and now my HDD is all unallocated. Now I wonder which OS should I install first. As you know, System reserved of Windows 10 is about 300MB and Windows 7 is just 100 MB, so I don't know how Win 10 uses that partition if I install Win 7 first. I also see on tenforums the thread about Dual Boot Windows 10 and Windows 7, with Win 7 first. So which is better, Win 10 first or Win 7 first?

You must always load the oldest first as it won't understand the boot sequence of new systems. Why not install Windows 10 then load 7 as a virtual system

Win 7 isn't compatible with Secure boot.
On BIOS, disable Secure boot and Fast boot.
I would create 3 partitions
- Win 7 - 85G
- Win 10 - 100G
- Data - remaining space
Once you have both (7&10) installed, change My Documents, Pictures etc to the data partition.

I would also create a small (5-6 GB) partition for portable programs.
I multi-boot and have a 6 GB portable apps partition with 50-100 portable programs on it.
It's nice being able to use one instance of a program by all OS's, less maintenance to update a program.
Also i can restore a backup image of any OS and all portable programs are untouched by the restore.
For me the biggest problem can be finding the portable version of a program, those download links are often harder to find.

Thanks for all your replies. My laptop doesn't have secure boot on BIOS, only legacy as default because it's a 2012 model. I just wonder which OS I should install first.
Here I have Win 10 first https://answers.microsoft.com/en-us/...e-bd507273a57d

Both win 7 or win 10 first is the same idea and I got it.
I just think about the System reserved partition. is there one better or the same?

On OEM (Dell, HP, Lenovo etc) the System partition has the boot loader and the program to launch Factory Restore.
If you install with a M$ installation disk, when you create a partition (from unallocated space) to have Windows installed, it also creates a M$ Reserved partition (120M). This partition is useless if you don't use bitlocker.
As suggested, install Win 7 fist. It will create a useless M$ Reserved partition. After you have installed, with disk manager, shrink C: and create 2 partitions. One for Win 10 and other for Data.
Boot from win 10 installation disk and install on the fist empty partition. It won't create another M$ reserved partition.
