Angels have the Phone Box
TC - I am thinking his System partition is either corrupt or too small (or both). With those partitions he has, that looks to me to be the problem. I am thinking......I have resolved partition problems for others by doing this: (not explicit instructions, just general so Ryantw don't follow this):
Boot to Kyhi's recovery media, use Macrium
Create a verified image of the hard drive completely (a fall back)
Clean install W10 on an unallocated disk (creates proper partitions-doesn't matter which version)
Boot to Kyhi's media again
Open Macrium, drag C partition from the image over to the new C partition on the fresh install.
It's a bit of work, but would clean things up for him. Do you agree his partitions are the problem?
EDIT: This would give him a clean W10 install without any HP bloatware, or other programs that may have come with the machine. It would also wipe his HP recovery partition.
