Toshiba Satellite W30T-A - Manual (Page 81)

When you reinstall the Windows operating system, the hard disk will
be reformatted and all data will be lost.
Please make sure to use the default Boot Mode option in the BIOS
setup utility before restoring.
1. Launch the BIOS setup utility.
Please refer to
TOSHIBA Setup Utility section for further information.
In the BIOS setup screen, select Advanced -> System Configuration
-> Boot Mode -> UEFI Boot(Default).
If you set the Boot Mode as CSM Boot, the recovery media created by
Recovery Media Creator will NOT be able to restore.
If you create a recovery image using advanced recovery tools from
Control Panel, please also make sure to use the default Boot Mode
option (UEFI Boot) in the BIOS setup utility before restoring.
1. Insert the Recovery Media into the external Optical Disc Drive or insert
the recovery USB Flash Memory into one available USB port.
2. In the Settings charm, click Power and then select Restart.
3. Hold down the F12 key and then release this key one second after the
computer is power on.
In tablet mode, hold down the Volume up button until the Boot menu
is loaded.
4. Use the Volume up and the Volume down button to select the
appropriate option from the menu according to your actual recovery
media and press the Windows button to confirm the selection.
5. A menu will be displayed from which you should follow the on-screen
instructions.
If you have previously chosen to remove the recovery partition and are
trying to create "Recovery Media", you will see the following message: "The
Recovery Media Creator can not be launched because there is no recovery
partition."
When there is no recovery partition, the Recovery Media Creator cannot
make Recovery Media.
However, if you have already created a "Recovery Media", you can use it
to restore the recovery partition.
If you have not created "Recovery Media", please contact TOSHIBA
support for assistance.
