Put the HP restoration disk in the optical drive. When asked choose Full Installation. (Destructive Installation)
DO NOT FORMAT without the disk. You will have a blank harddrive, and no operating system on it! Now you're in for a HARD time.
No restoration disk/s?
Contact HP Support.
(When the first owner gets the new laptop, not long after turning it on you are asked if you wish to make a BACKUP.
THIS,....is the Restoration Disk.
WELL....why didn't HP send it along?
Many users out there are afraid to attempt repair. Disk goes in a box in the basement, attic, or closet, or out to the trash.
Let's say the disk cost 50 cents. (Half dollar)
Take that times 50,000 computers, and half of the users tossed the disk away, or won't use it.
There goes $25,000 dollars in the trash.
Computer users are more educated now. Want to attempt repair themselves.
Computer manufacturers are starting to include the Restoration Disk/s again.
Backup saved on Drive D:?
Most of the time you can't access it.
Better to use the disk.
Also better to have the disk/s at your fingertips, then trying the DOWNLOAD over the internet junk.
What happens if a problem occurs again?
Better to have the disk/s.
Example from the USA;
The Restoration Disk is free.
