So I just bought a new hard drive for my laptop because my last one was having issues. I installed the new harddrive and it is recognized in setup under HDD... I am able to boot MemTest86 from my CD Drive but not the OS... I just get a black screen with one little blinking white bar... same if I try to boot from HD. There is no message of no operating system... it just goes straight to black screen with small white blinking bar... I had a Toshiba HDD2J14 and replaced with a Seagate 250gb... Both SATA drivers; however Seagate driver has specifications for SATA 6gbs/s Any help would be appreciated
