Windows 10: Win10 Dual Boot Different Hard Drives?

Hi all,

I have two seperate SSDs and I would like to install two seperate win10 for dual boot. I do not want to parition part of one hard drive and have both windows on one ssd. Ive tried searching but can only find articles on dual boot seperate ssd with Windows and linux. So is it possible? Secondly, if i were to get a virus on one ssd can it jump to the second? Thanks!

Edit: i should say i have a 3rd regular hard drive that i would want part of the one windows install but not the other. Is that possible??

Windows Boot Manager issue with Dual Boot on different Hard Drives

There are some misleading information in this thread.

1. Unlike Legacy MBR BIOS. When running Windows using GPT style partition, The UEFI firmware will update the boot configuration accordingly.
2. For each Windows using GPT with separate EFI System partition, You will have a separate "Windows Boot Manager" ie. you will have one for Windows 7 and one for Windows 10.
   NOTE: You must first connect the SSD/HD then restart or turn off the PC then turn on the PC for UEFI firmware to update the boot configuration.

There is nothing wrong with your Windows 7/10 booting. You just need to set your UEFI firmware to point to the correct "Windows Boot manager" and and set the SSD/HD to be the first boot device. Or using the Boot Menu for a one time boot.

It is hard to visualize how it works. So here's some screen shot from my PC.
From Disk Management: I have 2 Windows installed, 1 on disk 0 (Connect to Sata 0) and the other on disk 3 (Connect to Sata 5). On disk 2, I have 2 WinPE's (WinPE does not have Windows Boot Manager)



For one time boot from boot menu, I just have to select which one to boot from. Note that the 2 "Windows Boot Manager" associated to 2 different SSD ID's. #1 is for Windows on Disk 0, #2 is for Windows on Disk 3. #3 &#4 are for 2 WinPE's



For normal boot. On the next 3 screens, you'd have to select which "Windows Boot Manager" to boot from and also the appropriate SSD/HD.










NOTE: The GUI on my MB looks different from your MB but all options are there. In addition, If you disconnect your HD (Windows 10) then you would have to go back and reset the boot order again.

 

Dual Booting on Win10-64 with Win10-32 on seperate hard drives - goes corrupt every time

I'm trying to install Win10-64 bit as my primary drive and use a secondary Win10-32bit as a dual boot option. I have several old programs that run under 32 bit but want my main system to be 64 bit. Each time I install and have both drives ready, one of
them will report a disk error and the account or main user files will go corrupt on the other drive. I've done a clean install and also did the anniversary updates and keep getting the same corrupt startup problem. Any suggestions on how to fix this so I
can do a dual Win10 system?

Note: This is not a hard drive failure issue. Each time I do both OS installs the other drive will report an error after reboot and won't startup after the error. The permissions go corrupt to the files on the other drive and fails to boot after that.
This will happened to either drive after both installs are completed. This is also very frustrating as this is my sixth attempt do get the dual boot scenario and its has gone corrupt every time. A LOT of wasted time.

Best regards,

Derek
