I have recently installed Windows Vista on my system and it used to work fine for a couple of months, but just 2 days before, I started getting some problems with it, when ever i try to boot it then i can only get error message saying that:
So I tried to perform a System Repair from the Vista Installation Disk. As soon as I get the boot from CD option, I get the same Windows Boot Manager error that is listed above. The same OS dvd is wotking fine on other computer. Can anyone think of solution for this problem."A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source."
Info: Windows cannot verify the digital signature for this file.
