GRUB4DOS Toolbox for Windows

6. Add GRUB4DOS to bootmgr boot menu (Vista/2008 above)

This is intended for users of to add GRUB4DOS boot option to Windows boot menu, or to bootable NTFS partitions formatted in Windows Vista/2008 (NTFS5) and above with bootmgr in the root folder.

First select the bootmgr file you wish to use. A selection is only necessary if you want to operate on non-system disk/partitions. Next enter the GRUB4DOS mbr file name you wish to use, which is ‘grldr.mbr’ by default. Then specify the options for the GRUB4DOS entry.

After ‘Do It!’ button is clicked, the software will search for \Boot\BCD file in the same drive as bootmgr. If \Boot\BCD does not exist, the software will create one and add a boot option to load the specified GRUB4DOS mbr file; otherwise, an entry for the specified GRUB4DOS mbr file will be added to existing \Boot\BCD. If the operation is successful, details will be written to the log file along with a commandline to remove the GRUB4DOS entry.

For the GRUB4DOS entry to work, you have to manually copy the specified GRUB4DOS mbr file, and optionally its target grldr file too, to the same folder as the selected bootmgr.

Note that error and help messages which are displayed in GRUB4DOS commandline environment will not be patched. If a .lst file is provided, the built-in menu.lst of grldr will also be replaced.

9. Display UUID of mounted Windows partitions

This will list UUID(s) of all mounted partitions (except network and ram disks) in current Windows. The results can be copied to other text editor to be used for writing menu.lst files.

UUID provides more robust device selection independent of device enumeration sequence of BIOS, but you should pay attention to possible duplicate UUIDs created by some disk/partition cloning software.

Note: Although this task will display UUID of exFAT partitions on Windows with exFAT support, exFAT is not yet fully supported by GRUB4DOS.
