I have the above mentioned PC that has windows 10 pro installed. The issue:
Upon boot the PC stays on black screen for 5 minutes the shows login screen. After logging in the PC takes another 5 minutes on black screen before Windows 10 appears. After that the PC is wonderful.

Troubleshooting:
Created a second user account. The PC actually boots fast to the login screen and fast into Windows 10, however everything seems to work great except the Windows 10 start button and cortana. I can right click on the button and use it, but not left click or use cortana. I can however click on file explorer etc just fine.

Ran chkdsk /f, sfc /scannow, uninstall/reinstall graphics driver, no malware found, edit registry runonce processes per google, windows updates, uninstall antivirus and restart windows explorer in task manager, disabled all all startup items, uninstalled all hp software. Checking event viewer now for errors.

Note: This doesn't seem to be the same as the familiar "taskbar doesn't work at all" problem. Just the start button.
Note: There are no windows 10 drivers on the HP website for this model so cannot upgrade bios. Has an HP Mobo.

Go to Windows event log and check which service is taking a long time to start or is not starting at all.
This maybe help you investigating issue.

I suggest , given a damaged user profile , that you back up completely, and re-install Windows 10. Repair will not fix damaged profiles

Probably the reason is:  Driver incompatibility with Windows 10.

Nothing untoward there, but the main user profile is damaged (you said), and so reinstalling Windows is the best (and really the only) way to fix this.

One error repeatedly (20x) in event viewer after each boot:
Source: ESENT: Error: vcvhost (4808) Unistore Database (C;\Users\George\AppData\Local\Comms\UnistoreDB\sotre.vol: Index: 00000004 of table Partner item is corrupted 0

Also downloaded a Microsoft Start menu fixit which returns the following result:
microsoft.windows.shellexperiencehost & microsoft.windows.cortana are not installed correctly
However the fixit does not fix it

In this case maybe it would be smart to re-install Windows
