Windows 10: option to Boot into Windows 7 or 10

Wait until the grace period expires

 

Well I cannot predict the future. All I can say is what is today.

 

Its 30 days, By th way its in MS EULA.

 

Well we will see in 27 days. I do not interpret the MS EULA the same as you do. I believe that as long as you have a valid license for each OS installed then there will not be a problem. I cannot believe that MS is going to stop dual/multi booting. If that is the case then why even allow it for 30 days?

 

Absolutely! As long as you don't have (for instance) upgraded Windows 10 and the OS you upgraded from installed then there will not be a problem. Upgrading to Windows 10 effectively invalidates that license key for the OS you upgrade from as long as Windows 10 is installed. If you remove 10 then you can definitely reinstall the original OS and have it activate.

 

Now there is someone that reads the MS EULA as I do.

 

What If I get 2 licenses, so a new Windows 10 license. And if Dual Booting is not possible or restricted by Eula then why does Microsoft provide multi booting instructions on their support section ? (official article, not community thread on their forums)

 

zas17 you should all ready have a license for Windows 7 and you would need to buy a new license for Windows 10. You cannot upgrade Windows 7 to Window 10 and dual boot to both. You must install Windows 10 to a different partition with a new license. At this point you should be able to dual boot just fine.

It sounds to me that you may have a corrupt BCD store entry which can be fixed but is difficult to explain in this setting. Go into Computer Management and click on Disk Management. Verify that you can see both the Windows 7 and Windows 10 partitions.

 

If I needed to upgrade then I'd have earlier, I want both Windows 7 (not upgraded to 10) and Windows 10, that's why I'll dual boot. Currently I don't have Windows 10 installed, going to install later (next afternoon) and see what I can do. It's 1 am at my place right now.

Also when I have Win 10 I could see both the Windows 7 and 10 partition, and both were active and had the data. Originally Win7 is in Drive C: , on Win10 it became D: as Win10 became C: , but in Win7 again Win10 became I: (first partition on my secon HDD) and and obviously Windows 7 would be C: .

 

Well normally it should just dual boot after you install Windows 10, however that is not always the cause. Sometimes the BCD store is missing one of your partitions information. If this is the case then reboot with your USB stick and choose repair. Find and click Command prompt. Enter the following command bootrec /rebuildbcd when it finishes choose all. Restart you computer and you should see all entries in the boot screen

 

Well, I can believe they would do just that. Why? Because as was pointed out in a different thread, it's a free "Upgrade" to Windows 10, not a free Version of Windows 10.

It will be interested to see, in 30 days, just how many folks who are dual booting have their "old" OS suddenly deactivated.

 

You can predict the future. In an elevated (administrator) command prompt type slmgr /xpr and it will tell you how long the activation of that particular OS is good for.

 

On all systems I have dual booted, on the 2nd OS I have used the setup.exe in the Sources folder.

Well all five of my Windows partitions say: This machine is permanently activated. However, according to some people that is going to change in 30 days. And by the way 30 days from when? July 29, 2015? the day I clean installed Windows 10, which was August 1, 2015?

I let you all know on September 1, 2015.

 

The activations won't expire. As an example, I have Windows 8.1 and Office upgrades purchased from the Navy Exchange that are good for 3 PCs, but only have one key. After a couple of installs, whenever I try to activate one of the them, online always fails. I have to call the activation 800 number, enter the product ID, and a recording asks me how many PCs I have installed this on. I lie and say "One", and it always activates permanently. I am still within the three PC limitation of the software I bought. The only time this didn't work was when I answered "Three" to the recording and I got sent to a real person to whom I had to explain the 3 PC license I had.
