PC reset
Step One
Backup any data which you wish to keep before performing a factory
reset. You will probably want to copy everything from your user folders,
including documents, photos, music, and videos. The factory reset will delete
all these along with any programs you've installed since you got your laptop.
Step Two
Start-up or reboot your laptop.
Boot menu
Step Three
During the start-up process, hit the appropriate F key or key the combination listed below for your manufacturer.
Recovery partition key
Note: There is often a small window of opportunity to strike the key so
don't worry if it takes you a few attempts. We advise pressing the key multiple
times.
Acer – Alt + F10
Asus – F9
Dell/Alienware – F8
HP – F11
Lenovo – F11
MSI – F3
Samsung – F4
Sony – F10
Toshiba – 0 (not Numpad) while turning on, release the key when Toshiba logo
appears
If these keys don't work then lookout for a message on the screen
during startup which might indicate how to start the recovery process. You
might need to check your recovery partition is enabled in the BIOS. It's also
possible your laptop might not have a recovery partition (or it may have been
deleted) so we're making no guarantees here. You might need to contact your
manufacturer.
Step Four
You should see instructions on the screen explaining how to proceed.
Different manufacturers use different software to restore the 'disk image' from
the recovery partition, so we can't provide specific guidance. However, the
process is almost always automatic once you've confirmed you definitely want to
proceed, so it might be a case of waiting for 30 minutes for the job to happen
in one go, but some systems restore Windows first and then install drivers and
programs automatically when Windows first boots. If that's the case, don't try
to do anything until you see a message saying the restore has finished.
