Hello, I recently bought a Lenovo Y500 (i5 no cache SSD version). I quickly replaced the standard HDD it came with and swapped it with an SSD (OCZ Vertex 4) and installed W7. Ever since I made the swap, the only way I can get it to boot is if I press the recovery button on the side, hit load bios, then exit without saving. And viola, without changing one thing the computer boots fine. Loading up the bios and doing nothing seems to change something but I have no idea what. Other info: When I load the bios and exit to boot the computer, I see there is no drive detected at all. AHCI Mode Pressing the standard power button try's to have my nic card search for something to boot to. Computer works fine in all other aspects. So yeah, if anyone could tell me how to get my computer to boot normally without needing to enter/exit the bios every time that would be awesome.
