Hey, when i tried to boot from my 600Gb WD Caviar Black (SATA-3) with Windows 7 Ultimate 64-Bit it failed. When i turn my computer on it comes up with my motherboard's boot image then the monitor says there is no signal. I had a 160Gb WD Caviar Blue (IDE) but after hours of forum searching I removed the IDE cable from it. Then because my problem is so particular, I decided to sign up to a forum and post my problem to you brilliant guys.
