Can't boot to BIOS, my version of BIOS is American Megatrends Inc. V1.3, 11/7/2011. I've done about everything I could think of except for removing the RAM/Processer/MOBO out of the computer.

  • Exchanged keyboards
  • Pressed all combinations the would typically lead to BIOS
  • Mashed a whole lot of keys trying to get a keyboard error
  • Removed the hard drive containing the operating system and plugging in a USB with bootable media on it
  • Removed and reseated the CMOS battery

I'm not even seeing the typical motherboard/BIOS screen come up. Just a blank screen with a solid cursor in the top left and text that reads "B2" in the bottom right. It stays on that screen for a good minute or two then moves on to a completely blank screen on my second monitor.

Operating system boots fine. Currently trying to install Windows 10 onto a formatted Samsung 850 EVO SSD. (I had windows installed onto the SSD up until a few days ago and ran into some pretty mind-boggling issues so I decided on a format and a fresh install)

I built this system about 5 years ago, still using the same motherboard and processor I started with.

SPECS:

  • Windows 7 Home Premium 64-bit SP1
  • AMD Phenom II X4 960T
  • 8.00GB Dual-Channel DDR3 @ 666MHz (9-9-9-24)
  • MSI 970A-G45 (MS-7693)
  • 2047MB NVIDIA GeForce GTX 960 (EVGA)
  • 931GB Seagate ST1000DM003-9YN162 ATA Device (SATA)
  • ALSO - I was thinking of maybe flashing the BIOS. Wasn't sure if that might fix the issue, but on the American Megatrends site I have no idea which piece of software I need to install to do that. I'm starting to think this is an issue with the motherboard, but everything else works fine. There has to be a simple solution. Please help! – user530228 Dec 6 '15 at 0:07

B2 sounds like a BIOS "POST" code - the BIOS writes values to 0x80 and they can be read by a POST card, and some BIOSes may display such a code on a screen when encountering an error.

I found a site that lists POST codes for various BIOSes and boards - http://www.postcodemaster.com/inteldxxx.shtml - and on that page in particular there is this:

B2 Detecting presence of a fixed media (IDE hard drive detection etc.)

Perhaps your BIOS doesn't like your SSD for some reason. I recently tried getting an SSD working on an old Alienware laptop from 2004 - had an issue where the BIOS was unresponsive and I troubleshooted it down to an issue with the partition table.

So maybe it could be that, or something else with the SSD. Perhaps a newer BIOS gets along better with SSDs. You might try backing up your data from that SSD and updating its firmware. As a last resort consider getting an add-in PCIe card for your SSD and maybe then there will be less issues.

  • AHAH, a POST code, I assumed it was something along those lines, but couldn't pull up the information, I appreciate you finding it for me! Unfortunately, I don't think the post code is related, it hangs on that screen forever whether I have a drive in that can boot to the operating system or not. Currently I have no drives in and it still hangs on that screen for a few minutes. – user530228 Dec 6 '15 at 0:21
  • Also, If i put nothing but the bootable media in, that's what boots up. So I'm wondering if I can put the Windows 10 USB Media in, let that boot up, and then plug the SSD in and install Windows. Guess I'll find out. – user530228 Dec 6 '15 at 0:26
