Windows usually has a safety built in called system restore. Other than that and repair I do not know what you need to do other than reinstall.
You are talking about the primary operating system right?
Read carefully Perryg "Same problem with safe mode, after loading drivers I also get black screen".
So Windows loaded all system files in safe mode, everything goes futher, but I also got black screen.
Same situation with normal boot. "Starting Windows", I see animated logo, everything goes further and when I should see screen with user name etc. I just see black screen, nothing more."
I just installed VBoxWindowsAdditions-amd64.exe on my system (I am using only Windows 7 system).
I should install them on GUEST, not on my system (host). My mistake.
I extracted all files from VBoxWindowsAdditions-amd64.exe, I will try to connect my HDD to other computer, finding this files and deleting them from my disk.
Or maybe you can give me the list from installer with specified files\folders target dirs (I mean installator know where put files\folders while installing, so should have some list or something).
Or maybe any other solution? EDIT
Finally I fixed startup.
I extracted files from installator (VBoxWindowsAdditions-amd64.exe).
I found driver (VBoxSF.sys) file in installer ($SYSDIR\$\drivers).
So I started Windows 7 from CD, used Command Prompt, moved to C:\Program Files\system32\drivers, I listed all files there, I found a few VBox*.sys file, I deleted all (VBoxDrv.sys , VBoxMouse.sys , VBoxNetAdp.sys , VBoxNetFlt.sys , VBoxSF.sys , VBoxUSBMon.sys).
I deleted also dir Sun\VirtualBox Guest Additions.
After this action my laptop works fine, but I lost my mouse pointer (touchpad + USB mouse) :/
I copied VBoxMouse.sys back (to bring back my mouse control) to the System32\Drivers and I can use now USB Mouse, touchpad is still "dead" + KEYBOARD is now "dead". System starts/close SLOWLY. EDIT 2
I deleted again (using Win 7 CD and Command Prompt) VBoxMouse.sys (which I copied again) from System32\Drivers.
I've got keyboard control (no mouse).
I installed again VBoxWindowsAdditions-amd64.exe, BUT WITH OPTION "I WILL REBOOT MANUALLY LATER" (last info from installer).
After that I used Control Panel/Programs to UNINSTALL VBox Windows Additions.
After that I rebooted my laptop, everything is now FINE.
