I dont know what this black screen is called , but its the one, where u can choose which operating system u want to use .
for example if u installed Windows 7 and Windows Vista and u open ur computer it gives u a choice to choose which windows u wana use .
Basically i installed Windows 7 twice and now i have to choose between windows 7 and windows 7 the first one is the working one,the second one not. but it takes 28 seconds to be choosen automatically .
I was wondering if i can either decrease these 28 seconds to 1 second for example or just remove the second Windows 7 to make it run with the first one automatically .
