Windows 10: Why is my main disk showing 80 less GB after Dual-boot?

I have some old games that will only run properly in a 32bit windows environment, so I installed the 32bit version of Windows 10. When I went into "This PC", I saw that I had lost over 80GB of free space on my main C Drive. I have two disks in my pc, C and F. I partitioned F so that the partition would have 80GB of space It's not like I've added a whole bunch of file to that drive or anything. My main C Drive with the 64bit version of Windows was not partitioned. I booted into My 64bit Drive, but there was no difference in the free space of the disk. When I boot into the 32bit version, The 64

Dual Booting

Please follow the steps in the tutorial for how to post the screenshot. I cannot even see Disk 0, 1 and 2 on the drive map, and the columns were not spread so i can see the labels in the listings above even though it lllustates how to do this.

As long as you don't have a UEFI install then you can move the boot loader to Windows 10 so that it manages the Dual Boot using it's menu, add the Dual Boot back from there. These same steps using EasyBCD should do it:

Dual Booting with Windows 8.1


The procedure below will allow you to boot Windows separately or in dual boot configuration.
Here's what I recommend to do:

1. Disconnect the drive containing Windows 8.1
2. Install Windows 10 with one drive connected.
3. After step 2, reconnect the drive containing Windows 8.1
4. Boot up Windows 8.1. Open disk management and take a note of the drive letter of Windows 10 OS.
   NOTE: if you boot up Windows 10, then take a note of Windows 8.1 drive letter
5. Open Admin command prompt and type: bcdboot X:\windows where X: is the drive letter of Windows 10 (Windows 8.1 if you boot from Windows 10 in step 4)
6. Reboot the PC. You should have a dual boot screen.

NOTE: To break off the dual boot setting, Win+R->msconfig->boot and delete the none default entry on the list.

You initially asked:

is it possible to remove win 10 from dual booting?
Yes, of course it is!

What you probably wanted to ask is this:

• How to remove Win10 from dual booting
• How to remove Win10 from the disk

I already gave you an answer to your first question.

The answer to the second question depends on your disk / partition structure. Please use snippingtool.exe to post a picture of the Disk Manager frame (diskmgmt.msc).
