Windows 10: Win 10 installed on separate hard drive changes win 7

Thank you everyone for your time and suggestions! I solved the problem. Typed MSCONFIG in start menu and deleted windows 10 from the boot file. Now it boots directly to win 7.

 

Good deal. Does it give you a boot screen to select windows ten also?

 

charlie,

Yes it does. It gives you the option of windows 10 or 7.

 

Hi,
You'll probably have to that every time 10 updates and needs to boot
10 will switch the default os again.... that's why you should install 10 as a dual boot even when a different hdd or ssd is being used *Sad
Cheers.

 

Kevin.. Cool. You got no problems now. Welcome to TenForums and have a good night. *Cool

 

I hear ya!!! *Smile I have a strange problem. I have windows 8.1 on my computer and have windows 10 build 9926 on a separate hard drive on the same computer. I keep getting - on my Windows 8.1 drive, a message from my updater to download the newest version of windows 10. Is there some way to stop the attempted download of windows 10 on my Windows 8.1 partition? I love windows 10, but don't want to install it over my 8.1 partition since that is my main computer with lots of programs and information on it.
Thanks.

 

You have to hide the update to check if your pc will run 10, you probably ran it without even realizing it.

Always set your updates to " Let windows check for updates but to let you decide whether to download and install them"

I`m not sure what the update number is, I hid it a long time ago, there are threads on it and maybe another member will post it.

For some reason when I tried to install WIN10 on a separate drive from 8.1 and 7, I got an error message. To workaround that error message, I disconnected all drives with an OS installed and then installed WIN10. I then connected the drives with 8.1 and 7, when it is boot time I enter my BIOS and change the drive with the boot manager installed for the OS I want to boot. I now have 2 WIN10 (current build and previous) and WIN8.1 and everybody is fat and happy.

And that`s the way to do it .

It keeps all the drives independent from one another.

Very Good *Smile

 

The drive which is loaded with an OS has nothing but the OS loaded. My other files are split across 3 other drives, which holds files that can be shared, like my Outlook.pst. That way I can use my Outlook on any OS booted at that moment.

Was this a windows update, like a patch? I will have to start looking up KB numbers, I suppose.

 

Yes, there is an update to check to see if your pc can run windows 10, after you run that update your pc will upgrade to 10.

I have no clue why MS would offer an upgrade to a preview on a licensed OS, just crazy *Rolleyes

You have to uninstall that update, then run windows update, when it shows up again, you simply uncheck and hide it.

Please send feedback asking them to remove it, I already have *Smile

 

Had a similar issue with dual boot win7 and 10tp on same internal HDD. Advice of "Don't let them look at each other" is sound, indeed. What can happen is the earlier version (win7 in this case) is seen by 10tp as a threat and 10tp will, among other potential nasties, zap the restore points on win7. Short of disconnecting drives, not a choice in my case, take the drives "offline" via regedit.

The OS (C) on 10tp will see another drive containing the win7 OS(perhaps D) and possibly attack it. The same can happen in reverse, but not as likely. See attached example of .reg file. Modify it on 10tp to the drive letter it "sees" as win7, apply and reboot. Do the same on Win7 for the drive it sees as 10tp. After all done, both sides will just see a "local drive" which is "offline".

Only negative i've seen is bitlocker may cough at the offline drives at boot cause cryptographic service is trying to validate it. Does not cause any issues, I've had it this way on my box since 9841 in October.

Good luck!

 

Looked at the REG file. Is that HEX value of "1" on both drives? I've seen some posts that suggest a "1" on one and a "0" on the other and in the Windows Seven Forum they suggest a "1" on the drive that retains the restore points "only".

the 0 and 1 is used to enable/disable the offline status. Sounds backwards, but it's for triggering the function.

[HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\Offline]
"\\DosDevices\\C:"=dword:00000001

will make the "C" drive appear OFFLINE. This would be the reg key used on the drive/partition of Win 10.

The "C" will be need to be changed to whatever Win 10 "sees" the Win 7 OS drive/partition to be.

And, vice-versa...... on the WIN 7 side, change the "C" to whatever Win 7 "sees" the Win 10 OS drive/partition to be.

clear as mud, right! It works. *Cool

P.S. - The reason for "Windows Seven Forum they suggest a "1" on the drive that retains the restore points "only""
is that it's the only side that is REALLY necessary, cause WIN 7 is the earlier version which Win 10 sees as incompatible
restore points. It won't hurt to do both side. It will ensure no "leaking" betwix-and-between!
