Performance (OS)
NOTE: Most software problems occur as a result of the following:
● The application was not installed or congured correctly.
● There is insucient memory available to run the application.
● There is a conict between applications.
Make sure that all the needed device drivers are installed.
If an operating system other than the factory operating system is installed, check whether the operating
system is supported and the application is certied for the version of the operating system.
HP ships and supports Windows 7 with BIOS Legacy boot mode and Windows 8, 10 with BIOS UEFI boot mode.
Therefore, HP recommends that you switch BIOS boot mode from Legacy to UEFI Native for clean Windows 8,
10 installations, or to UEFI Hybrid (if available) for upgrading the option from Windows 7 to Windows 8, 10.
UEFI Windows 8, 10 avoids many unexpected behaviors (i.e., blue screen error, graphics/video issues) in the
BIOS Legacy setting.
