Windows 10: upgrade to windows 10 with multiple hard drives

i know its been asked before, but most of the related posts on the subject are almost 2 years old - millenia in computing terms

so im looking to upgrade to windows 10 from 7 - instigated by experiencing an oculus VR headset and touch controllers over the weekend and reading that most future VR titles will require windows 10 to run


friends and colleagues all assure me that it is a relatively easy and bug-free process these days, however i do have 4 hard drives in the machine to contend with:

1 SSD for the OS

1 SSD for games

1 SSD for work programs & data

1 HDD as a data backup


my understanding is that i should certainly unplug all the non-OS hard drives before applying the upgrade, however that any programs on the extra drives will not run after the upgrade and will need to be formatted / reinstalled


is this still the case?

Windows 10 upgrade rant..

The free space shouldn't prevent you from upgrading to built 1607. I manually upgraded my own laptop which had only 9gigs free space left on the system drive.

I unzipped the Windows 10 Pro anniversary edition ISO on my D drive, and started the upgrade process from there. At one point the installer complained about not having enough free space on the main drive, i just had to point it to the D drive to proceed to the next step. Now the rollback installation is stored there and doesn't clog up the C drive anymore.

In your case you could insert a large sdcard to act as the required rollback drive, i'm pretty sure it would do the trick.

Oh and by the way, if you want to further compress your System files:

• do a search Command Prompt, right-click it, and select Run as administrator.
• Type COMPACT.EXE /CompactOS:always and hit Enter.

You'll will gain anything from 2 to 4 gigs free space after it's done.
