Dual Boot 10 and 8.1 massacre

Ok, thought so. Thanks

We can figure out your booting problems from Windows 8, but we need to see the screenshot of Disk Management first to start with.

C is now this little partition with 8.1 on it

E has my Win 10 and all of my stuff on it

Ok. You are in good shape because the boot files are in the System Reserved partition at the front of the disk. Open an elevated ("run as administrator") command prompt. I can't remember exactly how to do that in Windows 8.1. Then run in the command prompt window:

bcdboot E:\Windows /d /addlast

Restart your computer and you should get Windows 10 / Windows 8 boot menu to choose from. After you successfully get back into Windows 10, we'll go from there.

i hit enter and it went back to command prompt. Was it suppose to do anything else?

OK sorry i didn't see the Boot Files Successfully created. Restarting now

Dudes... THANK YOU. I'm in 10... So relieved.

Now to get rid of 8.1 without doing the same thing all over again... ha.

Next, if you get into Windows 10, you will press Win + R key to bring up the run dialog. Type MSCONFIG and run it. Click on the boot tab. You should see the Windows 10 boot menu item set as the current OS. Make that also the Default OS. Change the timeout to 0 and click apply. Do not click make boot settings permanent. Restart computer again and you should go into Windows 10 without it asking you.

Once you are booting into Windows 10 without being asked, run MSCONFIG again, this time delete all the entries other than the Windows 10 which should now be the current and the default OS. Do NOT click make permanent. Apply and restart again. If all that is successful, then you can carefully delete only the Windows 8.1 partition and expand the Windows 10 partition back into the free space. Your boot files are in the 200MB partition at the front of the disk. Don't delete that one!

You were very clever to re-install Windows 8 to that empty space, we all completely overlooked that option!

Alright i made it default boot. Which is what i did that last time with easybcd but something obviously went wrong and it named C, E or something.

It wouldn't let me make the timer 0. it said 3 was the lowest. So at the restart there was a 3 sec delay, but 10 was now on top which i assume means top priority. And it's still default in boot. So what do you think?
