Something went wrong

I had followed this tutorial: How to Dual-Boot Windows 10 with Windows 7 or 8 to dual-boot Windows 7, 10.
After a while I found out that I would like to revert back to 7 only and followed this tutorial: 'How to Properly Delete a OS in a Dual Boot' found here on sevenforums.
Everything went well until I attempted to exit EasyBCD when I got this error message:



Now what?

Actually UNINSTALLING an OS

Shawn,
I inadvertently did a WIN7 new install on a partition which has data. The data appears to have remained intact. So I was examining this tutorial about deleting an OS. I have already removed the unwanted OS from the MBR. However, this tutorial advocates deleting the partition to remove the unwanted OS. Since I have data I do not necessarily want to do that. Is there a tool that will actually UNINSTALL all of the components of an OS system while leaving everything else intact?

I think I know your answer already, but I thought I'd see.

where is the bootmgr located?
If nothing is listing that partition as having a bootable OS, then it's data and can be deleted with windows explorer without deleting or formatting the partition.

That is partially true, but you will run into permission issues with the \Windows\System32 & other directories as well. You can try to take ownership of everything, but that can be a chore.

I was hoping there was a simple tool that would do the job.

right-click and left-click on "take ownership"

even though it's not recommended, I enable the big dog (real) administrator account (in the local security policy) being "an administrator" is different than being "the administrator", as soon as I install a system. I've never had trouble deleting anything that's offline

I already did it by booting from a WIN7 disk so the CMD does not care about priviledges when executed in that fashion.

Cant move Bootmgr Win8 is Logical.

Hi, This is my situation, i will try to be clear.
I currently have a Dual-Boot system, with Windows 7 & 8.1. I want to remove the W7 installation, and be left with just W8.1, but I am running into Problems. Firstly my setup..
ONE HDD, currently with the following partitions (In this order in Disk Management, booted into Win8.1)...
DISK 0
* UNALLOCATED 107.79Gb
Win7 (D) 111.23Gb NTFS (System, Active, Primary Partition)
Win8 (C) 79.06Gb NTFS (Boot, Page File, Crash Dump, Logical Drive)

I understand that as the Win7 is "Active' then that means i need to copy the BootMgr info to the Win8 before deleting it, but when i try to do that with EasyBCD, it fails telling me i cannot move the boot info to a Logical Drive, and to convert the drive to Primary. So, I tried using Easus Partition Manager to convert, it tells me I cant convert the System or Boot partition.

I am currently at work and doing this remotely via TeamViewer (logged in to Win8), so I am looking for a way to do this WITHOUT having to boot into the Win7 as i cant do that from here.

I am assuming the answer is to boot into Win7, install Easus and then convert the Win8 partition, then boot back into Win8 and use EasyBCD to copy the boot info, is there another way, am i missing something?

Thank you in advance.

got any 3rd party backup software? Image ei8ht and recover over the se7en installation.

Is ei8ht really installed on a Logical Drive in an extended partition and is the unallocated space really at the front of your drive? What caused the dump file?
