Black screen with short white strips after Windows restart
I have HP ProBook 430 G1 with pre-installed Windows 7 Professional 64bit. After clean system installation I have resized Windows partition and created new partition for Ubuntu. I also removed HP_Tools partition. After that (I don't know if it happend before resizing partition) when I start Windows and restart it from Start menu I got black screen with white short strips. I see it for about 10-15 seconds and Windows start normally. It happens after choosing Windows from boot menu but before Windows logo appears.
It only happens after system restart. It doesn't happen when I start system for the first time after turning on computer.
I uploaded photograph of the screen as an attachment.
Anyone has any ideas what causes this problem?
Now, after I was hitting F8 to start safe mode this screen appears everytime - no matter if I start or restart computer.
