Upon installing windows 7, the ubuntu boot menu disappeared, and I tried to fix this using a variety of software. I have windows 7 (64 bit) and Ubuntu 12.04 (64bit) installed on my laptop. When the patched GRLDR files can no longer load, the “No GRLDR” error will appear on your screen. Once the BOOTMGR refuses to load unsigned Windows kernels, “grldr” is used instead. For Windows 7 and Vista to pass validation tests and Windows activation, certain codes are added into the boot process thus modifying the BOOTMGR. If your PC did not come with a Windows installation disc or if you no longer have your Windows setup media, you can use Easy Recovery Essentials for Windows instead. Fix no g2ldr in Windows Vista, 7, 8 or 8.1 Windows Setup CD/DVD Required! Some of the solutions below require the use of the Microsoft Windows setup CD or DVD.
