black screen of death

Hi, please note this from HP:
HP PCs manufactured before August of 2013 might not have a complete set of hardware and/or drivers required to use all of the features in Windows 10.

• HP is not testing or developing Windows 10 drivers for these PC products.
• If you choose to use Windows 10 some features, applications, and connected devices might not work as expected.
• If you still wish to proceed with using Windows 10 on an untested system, please visit the Windows support site for information and support.

Your HP Pavilion 23 appears to date from around 2012-13

Note that on each feature update (upgrade) MS gives you a new set of drivers. Some people with older PCs find that something breaks when the next upgrade occurs.

You may find updating your BIOS helps, if an update is available.

To help you avoiding continually installing Win 10 again and again, why not use disk imaging (which many here most strongly advocate) so when things go wrong you can simply restore an image and be back where you were- even if you need to replace your disk.

E.g. Macrium Reflect (free).

You might try turning off Fast Startup, but I can't think of a way to identify the black screen problem just now.

It's also possible that as you seem to update from Win 8 to build 1607 (how- is that via Windows Update, or by using a 1607 iso or boot medium with 1607 on it? -

i found the usb installation

- ) that you are encountering an attempt to upgrade your PC, but that's not how that usually fails.

You may want to invest in an external disk for your disk image storage. Very roughly estimate the compressed partition (that's what an image is) will be 50% of the selected used space for the initial (base) image for Windows. (Macrium r has an option to automatically select all the Windows partitions - 4 for UEFI typically). If there are many compressed files e.g. music, video, the space required will be larger. then add to that a set of , say, 5 differential images, each, say, 30% or less of the base image depending on the amount of difference and that says you need a disk of, say, 500Gb minimum. Note you can image any disk/partition combination.

Important that you confirmed you 'd not had difficulties until this week. My guess is some update or upgrade has caused an incompatibility.

As I suggested, a possible BIOS update might help if you were lucky, but you may simply end up needing to stay with a particular Win 10 build and not upgrade further.
