Use this procedure to boot a system that is currently at run level 0 to run level 3.
# reboot
If the system displays the Press any key to reboot prompt, press any key to reboot the system.
You can also use the Reset button at this prompt. If the system is shut down, turn the system on with the power switch.
When the boot sequence begins, the GRUB menu is displayed.
If you do not choose an entry within 10 seconds, the system automatically boots to run level 3.
The login prompt is displayed when the boot process has finished successfully.

Use this procedure to boot a system that is at run level 0 to run level S. The single-user level is used for performing system maintenance.
Note - This procedure can be used for all GRUB implementations. However, the boot entries in the GRUB main menu vary, depending on which Oracle Solaris release you are running.
For a description of all of the kernel options that you can specify at boot time, see x86: Modifying Boot Behavior by Editing the GRUB Menu at Boot Time.
# reboot
If the system displays the Press any key to reboot prompt, press any key to reboot the system.
You can also use the Reset button at this prompt. If the system is shut down, turn the system on with the power switch.
When the boot sequence begins, the GRUB menu is displayed.
If you cannot use the arrow keys, use the caret key (^) key to scroll up and the letter v key to scroll down.
From here, you can add options and arguments to the kernel or kernel$ line.
The following alternate boot behaviors can be specified in this manner:
Perform a reconfiguration boot
Boot a 64-bit capable system in 32-bit mode
Boot the system with the kernel debugger
Redirect the console
For more information, see the boot(1M) man page.

Use this procedure to boot a system, if you need to specify an alternate kernel or an alternate /etc/system file.
To specify an alternate /etc/system file when booting an x86 based system interactively by using the boot -a command, follow these steps:
1. Make backup copies of the /etc/system and the boot/solaris/filelist.ramdisk files.
# cp /etc/system /etc/system.bak # cp /boot/solaris/filelist.ramdisk /boot/solaris/filelist.ramdisk.orig
2. Add the /etc/system.bak file name to the /boot/solaris/filelist.ramdisk file.
# echo "etc/system.bak" >> /boot/solaris/filelist.ramdisk
3. Update the boot archive.
# bootadm update-archive -v
# reboot
If the system displays the Press any key to reboot prompt, press any key to reboot the system.
You can also use the Reset button at this prompt. If the system is shut down, turn the system on with the power switch.
When the boot sequence begins, the GRUB main menu is displayed.
Enter default directory for modules [/platform/i86pc/kernel /kernel /usr/kernel]:
Name of system file [etc/system]: /etc/system.bak
Pressing Enter without providing an alternate file accepts the default.
Repair the damaged /etc/system file.
