Windows 10: 2 HDD In one PC WITH 2 Different OS

I have two HDDs, one with license Vista and one with License Windows 10 , can I use them both in same pc and choose whatever OS and HHD I can use?

If yes how to do that?

:)

 

Recommended setup with 2 hd and 2 os

I have a Thinkpad T420 laptop, with 2 hard drives:

• SSD drive, 128GB, GPT (disk1)
  
• normal HDD, 5400 rpm, 500GB, MBR (disk2)
  

I need to run 2 OS in this laptop: Windows 10 + Ubuntu 16.04. So, I've decided to:

1. Install both, Windows 10 and Ubuntu 16.04 in the SDD disk (disk1). It's a gpt disk, and contains partitions for both OS. Working fine.
   
2. Install everything not considered "part of the OS" in the other drive (disk2), for both OS. So, I've created 2 partitions: ext4 and ntfs. Moved the home folder of Ubuntu 16.04 to the ext4 partition. No problem at all.
   

Ubuntu runs fine with this configuration. The problem is with Windows 10. It won't start (stuck in the loading windows splash screen). If I delete the ntfs partition of disk2, it runs. Then, I try to create again the partition in disk2, with native disk management tool and with Easeus Partition Manager. Not working. It hangs, and I need to fix things again from Ubuntu with gparted.

So, my questions:

• Can't I have a gpt disk and a mbr disk in the same machine? Can't Windows 10 and Ubuntu handle that? Ubuntu works fine with it, but Windows is crashing
  
• If my problem is not related with both disks having different partition schemas (GPT and MBR), what could be the problem? Why Windows can't handle both disks?
  

I can provide specific hardware information if needed. Many thanks in advance

 

Type Cover 2 not working with WIndows 10 (Release)

So, after suggesting checking for firmware updates, it does appear there was a firmware release July 23, 2015 that resolves this issue. The step-by-step directions as well as the firmware release history for the Surface Pro 2 can be found here.
