I have HP Pavilion dv7 Notebook with switchable graphics bought year 2012.
I have had almost all the time problems with those 2 graphics drivers (AMD HD 6770 and Intel HD Graphics 3000)
HP do not have made new switchable graphics drivers (for example for Windows 7) for years and everybody can see that internet is full of very disappointed and frustrated comments of that!
Now when I updated my Windows 7 to Windows 10 It became one big problem caused by switchable graphics. Booting time became very long - terrible long!
It came black screen that lasted 1 minute 25 seconds!
I tested it and took those graphics driver away and then - that black screen was only 2-5 seconds.
I discussed with Microsoft technician (in Finland) and he said that they put only the basic drivers to Windows 10 and this time it do not work normally.
HP is responsible for those special correctdrivers!
I have not found correct drivers from HP-support sites (Have any other??)
But there is one good way to solve that problem!
I installed from Leshcatlabs.net (Catalyst 15.7 WHQL UnifL v1.2)graphics drivers
Downloads - leshcatlabs.net
And everything works fine - that blank screen is now only 3-5 seconds and switchable graphics works normally!
(First install Intel driver and then AMD driver and that is all!)
Driver support by PC assemblers often is poor: While the hardware manufacturer himself still does offer updates, the assembler often does not update his customized drivers.
Intel offers a current driver for that graphics card: Intel Download Center
As far as I can tell, using that driver, the Intel HD 3000 graphics card is working correctly under Windows 10. (Although Intel marked this driver as "for Windows 8.1" and not for Windows 10, it is in fact working better for me under Windows 10, than it did under Windows 8.1. Using this driver, I had small glitches in Windows 8.1, which I do not have with the same driver in Windows 10.)

I installed those drivers (Intel and AMD) and that black screen during boot is now 1 minute 10 seconds - so, what you said - did not work!
One more thing!I installed those drivers (Intel and AMD) and that black screen during boot is now 1 minute 10 seconds - so, what you said - did not work!
When I installed that Intel newest HD graphics driver, and uninstalledAMD HD 6770M driver, that black screen disappeared!(but like we know, switchable graphics did not work any more)
