I recently bought a new Asus laptop with Windows 8 on it. After a week of hating it, I did a clean install of Windows 7 on the machine. I had to disable SecureBoot in the BIOS to even be able install Windows 7 from disk. Anyway, the installation went fine, and I'm running Windows 7.

In Computer Management in Windows 7 I found an old OEM (EFI System) partition which I would like to remove. But I want to do this without formatting the entire drive, as Windows is now working really well.

This is my current setup of partitions. I want to merge that first nameless partition with G: if at all possible. Computer Management doesn't allow me to do anything with that locked partition.

enter image description here

I tried to remove it with DiskPart.exe With this tutorial

But it told me I could not remove system directories.

Is there anyway I can keep Windows 7 working, but remove that annoying locked partition?

I think that these partition is required for EFI systems to boot, so it is not a good idea to remove it. Moreover, it's only 300 MB on a 1 TB hard drive. – Pincopallino Apr 6 '13 at 13:10

DO NOT REMOVE THE EFI SYSTEM PARTITION (ESP) FROM AN EFI-BOOTING COMPUTER! That partition is required to boot the computer, so removing it would result in an unbootable computer! If the computer were booting in BIOS mode, it would be safe to remove -- but because Windows ties its partition table type to its boot mode, it seems quite unlikely that you'd have an ESP on a BIOS-booting computer.
