Problem:

When I turn on the machine, only a white cursor appears on a blank screen.

Solution:

Note: If you have modified a partition on your HDD or SSD by using a partition software, information about that partition, or the master boot record, may have been destroyed.

1.Turn off the computer, and then turn it on again.

2.If you still see only the cursor on the screen, do the following:

vIf you have used the partition software, examine the partition on the HDD or SSD by using the software, and recover the partition if required.

vUse either the Rescue and Recovery workspace or the recovery discs to restore the system to the factory state.

For details about restoring the system to the factory state, see Chapter 4, “Recovery options,” on page 35.

3.If the problem persists, have the computer serviced.
