Sometimes referred to as the recovery partition, the hidden
partition is a partition found on OEM computers
such as Acer,
ASUS, Dell,
eMachine, and
HP (Compaq) computers that allow a
user to restore their computer back to how it was when it was first purchased, without
using a CD or DVD.
Hidden partitions are accessed
either through Windows using a pre-installed application that came with the
computer or by pressing a key combination as the computer boots up. Below are
some examples of how to access this partition as the computer is booting up.
Often it's easiest to press the key mentioned below over and over as the
computer is booting up or if it's two keys holding down the
modifier key and then pressing the other key
over and over.
Tip: Before
doing any of the below steps make sure any
USB
devices and drives are disconnected and that no CD or other disc is in the
computer.
- Alt + F10 - Access Acer disk-to-disk (D2D) recovery partition. Note: you may need to enable the D2D option in CMOS setup.
- F9 - Access ASUS EEE PC hidden partition.
- F10 or F11 - Access the Compaq (Hewlett Packard) recovery partition.
- Ctrl + F11 or F8 - Access Dell computers Dell System Restore (DSR) partition on many different models.
- F11 - Access eMachine option to restore a backup copy.
- F11 - Access Gateway hidden restore partition
- F11 - Access Lenovo hidden recovery partition.
- F10 - Access Sony hidden restore partition.
- 0 (zero key) or F8 - Access Toshiba hidden partition.
Finally, you may have the option between a Non-Destructive System Restore and
Full System Restore. For computers that have the Non-Destructive System Restore
option or an option similar, we suggest trying this option first. This can
resolve a lot of Windows related issues without erasing of your personal data
such as family photos. For more serious issues or if the non-destructive option
doesn't work do a Full System Restore. This will delete all files on your
computer, however, it will resolve any software issue with your computer.
Tip: If your
computer did not come with this hidden partition or you've deleted it the only
way to restore your computer would be to use a Windows CD and boot from that CD.
However, this will only re-install Windows and not any of the other software or
drivers that came with your computer.
