When you say the Start Menu is broken, to clarify, it doesn't launch or all the icons are missing or corrupted?
If it won't launch try this:
1. Fix corrupted files
If the Search bar still works, search for powershell. Then right-click Windows PowerShell in the search results and select Run as administrator.
But if the search bar doesn’t work either, press Winkey-R, type powershell, and press Enter. Right-click the PowerShell icon on the taskbar and select Pin to taskbar. Close the PowerShell program. Hold down Shift and Cntrl while you right-click the PowerShell icon again. Select Run as administrator.
Once you’re in the Powershell command-line environment, type the command sfc /scannow and press Enter. Then wait. It can take quite a while.
Eventually, the program will tell you either that it found no corrupt Windows files, it found and fixed them, or it found some but couldn’t fix them. If you get the latter response, try the command
dism /online /cleanup-image /restorehealth
This should (hopefully) download replacement files.
2. Remove and reinstall your Metro/Modern apps
Relax. This isn’t as bad as it sounds. First of all, this only effects the Metro/Modern/Windows 10 apps that you get through Microsoft’s Store. Old-fashioned Windows programs won’t be affected.
Second, it’s all automated.
Open PowerShell as an administrator as described above. Type in the following command—or better yet, just copy and paste it:
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
When it’s done doing its job, reboot.

If this doesn't work I have had good luck just creating another user account and copying my personal files there. You can test if that works without going through all the trouble just create an account and check the menu.
