Technology Project: Cleanly format and restore Compaq Presario C500 laptop
Took a bit of researching through Google to find the best method to simply erase all the adware, malware, and other random junk accumulated on a laptop over 5 years of usage and restore it back to the stock factory condition.
Turns out, Compaq/HP have a recovery partition on the machine but it is not marked as active and therefore not visible to the bios as a bootable partition. Once the partition is visible and bootable it can be accessed through the boot menu, F11.
The quickest way I was able to toggle the status on the partition was with the directions below, found here:
While in windows, START > Control Panel > Administrative tools or
START > run > compmgmt.msc and press enter.
Open Disk management
Locate the recovery partition (usually smaller and at the end of the disk).
Right click on the partition and mark partition as Active.
Reboot and press F11. This should now boot the recovery partition and restore the Compaq Laptop.
This worked for me on a Compaq Presario C500.
