Make a copy of the grldr file and rename it to memtest. Click on the Save current system button and then Close. Edit the OS title the text that will appear in the Windows menu. Note: A solid black checkbox indicates 'not defined in BCD'. Use the Add button to add a new RealMode entry. For instance, suppose we want to add memtest to our Windows bootmgr menu. This means we can have a Windows bootmgr menu with multiple entries which point to different grldr files and instantly run any payload we like. However, we can instead, boot directly to the grldr file from bootmgr by configuring the Windows BCD file.Īlso, we can edit the embedded menu inside the grldr file to boot to any payload directly, so we do not have to load a grub4dos menu first.

Here is the standard embedded config file inside grldr 0. This is normally used to look for the users menu.

The grldr file contains an embedded pre-boot menu.
