Triple Boot Windows 7, 10, Linux Mint

[austin_m]

Hello! I have a question about triple booting. I Currently have Windows 7 and Linux Mint Sarah installed on two separate ssd's on my computer. I would like to add a third ssd and install Windows 10 to my system as well. How would I go about this process if it is possible?

I run W10, W7 and Linux mint on same machine but each on separate SSD, no problem there. Important part is to install each OS while other disks are disabled. I made my computer BOOT of fastest disk (Samsung 960 evo) and use http://neosmart.net/EasyBCD/ on W10 to make BOOT menu and choose which OS to run.

I messed something up. I downloaded EasyBCD in Windows 10. It detects the Windows 7 drive but not the linux one. When I try to boot the computer, it wants to got through check one of the disks for recovery.

I then tried EasyBCD on Windows 7. That allows me to see all of the drives, but I can't boot into Windows 10 and it also tries to check the disk when I boot into Windows 7.

It has to be installed in and set up on first boot device BIOS points to.

That is what I did. On my first attempt, I had windows 10 set as the first boot device. I installed EasyBCD and could only add an entry for Windows 7, the option to add Linux Mint was greyed out. I did try it out and aside from not having an option for Linux Mint, it worked.

Because of that, I then installed EasyBCD on Windows 7 to see if I could add Linux to the boot menu. I was able to do that. I then switched the first boot device to Windows 7. I can now access Windows 7 and Linux Mint, but Windows 10 displays a message that it can't boot do to a "hardware change".

Regardless of which way I have the first boot priority; when I select which OS I want to boot into, Windows wants to check to check the disk. If I let it, it validates that there is no errors and boots into the selected Windows.
