Delete Ubuntu from dual boot Windows 8.1 in GPT disk

Question

I'm using Windows dual booting with Ubuntu.

I have uninstalled, and at that time my disk was formated as MBR. After deleting all partitions of Ubuntu I choose to rebuild the MBR in my disk. That way I was sure not to loose the Windows boot loader.

Now I'm using a GPT disk. I want to delete Ubuntu but I'm scared I will loose my Windows boot loader.

Solution

Press Win + R to get the run box, type diskmgmt.msc and press enter.

• Just click with right mouse button on the Ubuntu partition, and choose to Delete Volume.

• If Windows 8.1 was preinstalled on your computer, please ensure you don't remove recovery partitions, etc.

• The space formerly occupied by Linux should now say "Unallocated".

• And Now Right-click on C: and "Extend Volume" to increase the size of drive C using the unallocated space.(NOTE: You can replace any drive letter instead of C: that you shrink it before for installing Ubuntu)

• If you were using grub to dual-boot (most probably), then you may need the windows 8.1 CD to fix the boot manager and make Windows 8.1 bootable again.

How to fix your boot manager :

1. boot your system using windows 8.1 installation CD or flash drive
2. go to "repair your system"
3. use command prompt (Troubleshoot ► Advanced Options ► Command Prompt)
4. type bootrec /fixboot then hit enter
5. type bootrec /fixmbr then hit enter
6. exit

This time your system will boot directly into windows.

This is the safe way to uninstall Ubuntu.

Do you have windows 8.1 boot loader to select which OS starts or Ubuntu Grub boot loader?

Thanks! This worked. Tried dual w8.1/ubuntu in my laptop Samsung RPC512 and the OS(linux) broke after the system update.
