Hi


Since I want a hackintosh and need to delete a windows 8 CP......I tried to delete via disk management on windows 7....but I can't delete or format windows 8 partition like in picture

You cannot delete Windows 8 (drive D) as it is Windows System partition - the System partition in Windows has the boot files !

1. Mark Windows 7 partition as active.
2. Reboot to Windows 7 Repair CD/DVD/USB and run StartUp Repair up to 3 times with rebooting.
This is the recomended way on "sevenforums".

Partition - Mark as Active - Windows 7 Forums
Startup Repair - Run 3 Separate Times - Windows 7 Forums

Have a look at this: Dual Boot - Delete a OS - Windows 7 Forums

Not sure if you've handled this yet, but here's an easy way how.

Copy bootmgr file from D: to C:

Copy boot folder from D: to C: and skip over the files it tells you it can't copy.

Open an elevated command prompt and run this command:

bcdedit /export C:\boot\bcd

Now set C: to be the active partition in Disk Management. Reboot and now you can format D:

Be sure to also remove the reference to D: in the bcd. You can use EasyBCD for that.

That is certainly one way of doing it - except you will still face the double boot screen because you have not fixed the MBR.

EasyBCD's "Edit Boot Menu" tab has a box to check to "Skip the boot menu".

Why not just clean-up the MBR with EasyBCD.

From what I recall, EasyBCD has an option of "migrating" the Windows boot loader files from one partition to another, and in the process, updates the MBR accordingly.

I think also have the option to Repair the boot files.

So, if the boot loader files are in the Win7 partition, after removing the Windows 8 partition, you would just use this EasyBCD Repair option and you would be OK again.

Fixed.....Just delete windows 8 CP via windows 7 installer......and fix booting with windows 7 repair tool on windows 7 DVD
