Is it possible to 64bit on one drive and 32bit on another? I tried and it ran fine for a day or two, then my drives became
corrupt.
I know if your pc is 64bit that it will run a 32bit OS. So seems like its possible. But sounds like you had some trouble so maybe not so much.
Possible yes, legal no.
See later post n this thread: Running two Windows 10 - Page 3 - Windows 10 blog
Why not legal?
@man00
If they were upgrades from two different legit OSs I don't see why not. If from one OS, no.
Nothing illegal about it. Gabe Aul stated months ago that dual booting Windows 10 on the same license is OK. This is a change from previous versions of Windows and is due to the change to Device Activation with Windows 10. The architecture is irrelevant to this (32 bit vs. 64 bit). What would be illegal would be to install the two architectures on two different computers on the same license, but on the same computer is OK. With device activation I don't think it can be prevented anyway, especially with retail licenses.
With corrupt you mean you cannot access both drives when booting or in another stage?
What message do you get?
Yes, if booting from the 64bit, it would not anything that the 32bit was on..same if booting from 32bit, it wouldn't see anything on the 64bit drive
How are the 2 hard drives formatted?
You can't see the other system from either system? Is that what you mean by "corrupt"? Do either systems boot?
