x86: How to Add a Boot Entry to the GRUB Menu

Use the add-entry subcommand of the bootadm command to add a new entry to the GRUB menu with the specified entry title. If you specify an entry number, the new entry is inserted at the given position in the GRUB menu. Or, if the entry number is higher than the current number of entries in the menu, the entry is then added as the last entry in the menu.

Assume the root role.
See Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.3.
(Optional) List the current boot entries in the GRUB menu.
```
# bootadm list-menu
```

Add the new boot entry to the GRUB menu.

# bootadm add-entry -P pool -i [entry-number] entry-title

Set the bootfs property for the newly added entry as follows:
```
# bootadm change-entry -i new-entry-number bootfs='pool-name/ROOT/be-name'
```
This step ensures that the newly added boot entry does not use the default bootfs value that is set in the root pool, which is specified in the bootfs pool-level property.
Verify that the boot entry was added.
```
# bootadm list-menu
```
Note - If you do not see your changes, check the grub.cfg file to verify that the change was made.

1 Oracle Solaris 11.3
# bootadm add-entry -i 2  Oracle Solaris 11_test
# bootadm change-entry -i 2 bootfs='rpool/ROOT/test'
# bootadm list-menu
The location of the boot loader configuration file is /rpool/boot/grub
