SSD in Windows but not in BIOS!

Hi everyone,

I installed a Crucial MX100 (my very first ssd) on my Asus P8P67 last Friday, and it was like being born again, but with tears of joy this time :)

Unfortunately, this morning, after a computer crash (video in Internet Explorer), my computer couldn't reboot on the ssd. It booted on my old HDD instead. In Windows, I could access my SSD normally, so I think it's not dead.

However, when I go in the BIOS to set the boot priority back (to boot on the ssd), I can't see the SSD in the list bootable devices! What's happening? Do I need to RMA it? Is there a quicker way to bring that piece of heaven back into the BIOS? Please say yes...

Thanks for reading :\

Did you try F8 and make sure the drive isn't listed in the boot menu?

If you don't see it, make sure the SATA cable is secure on both ends (and power cable while you're at it), and if it still doesn't work, try replacing the SATA cable.

Thanks for your answer.

I did check in the boot menu, and it wasn't there! I could only see my HDD, DVDRW, and HP printer!

However, when I run windows from my HDD, I can access the ssd completely normally (but it's not the main drive obviously).

Basically, it's in Windows, but not in the BIOS.

Damaged windows files on the SSD, maybe?

I'll check the cables at home this evening.

Thanks again

Could be. That is a strange one, with the drive being seen in Windows but not in the BIOS, but I know that on the Asus I have now it took me a while to get used to the manner in which it lists, and doesn't list, drives in certain menus.

I am sure that the SSD is detected in BIOS. Otherwise you would not be able to access it from Windows.

Detected in BIOS is one thing. A bootable device is another thing. Maybe the boot flag (if using MBR) is missing, maybe some files on SSD are corrupted.

First thing to check: boot from HDD, go to Disk Management and check to see if the SSD has an Active partition.

Just press F8 after the bios post screen! That MB seems to support UEFI BOOT. IF your SSD OS was installed in UEFI BOOT mode, that OS will boot only in UEFI MODE. Maybe the system crash screwed up the boot order/boot type setting. Make a test! Boot from the ssd in legacy then in uefi mode by choosing the drive from the F8 quick boot menu. Find out the correct option, then make the proper modification in BIOS!

I didn't even take off my shoes to try what you guys suggested. First I tried the F8 when booting and the SSD appeared! And it worked! It's running Windows from the right now!

Thanks for your help guys. I promise this morning it did not appear in the list of bootable devices in the BIOS, I really wonder what happened. Hopefully it won't happen again.

Thanks everyone!

Basic mistake - having both bootable drives connected and installed.

Well, it worked 2 days like this without a problem. There are two bootable devices, one (the SSD) has priority over the other (the HDD).

The problem was that the ssd had 'disappeared' somewhat from the bios and the computer naturally booted on the HDD instead.

I guess the next step would have been to try and boot with just the HDD plugged in. EDIT Sorry, I meant 'with just the SSD plugged in'

Don't rely on priority - it doesn't always work Once the HDD boot drive has been replaced, you should remove it or delete the OS from it so as to make it non-bootable.

I would try disconnecting all hd's except for the ssd and see if the bios will see it. I had to do this recently with my evga z87 ftw to force it to see my ssd and select it as the boot drive. If it does then leave the other bootable drive disconnected from now on. I keep an extra hd with a copy of windows standing by just in case my ssd goes down so I can come right back up with a working machine.

Coming back from work, my computer booted from the HDD again, so I went in the BIOS to look into it more closely, rather than by pressing F8.

It turns out that the SSD was indeed misssing from the list of bootable devices, but I went into another menu where all possible devices can be chosen (while the other menu was about device priority).

So I removed the HDD from there, and just left the DVDRW and the SSD.

Thanks for all your help guys.

I don't know if this is just an Asus thing, but when I put in a couple drives for imaging I found this to be the case as well - the SSD is not listed in the main BIOS screen. In my case I just use F8, as the next reboot will be to remove the drives. In your case, you chose correctly. I am sure to some Asus technicians, their setup makes perfect sense. But I personally don't see why a person wouldn't want all their drives to show up on the same page.
