    Reset BIOS so that it first checks CD/DVD drives, & then boots normal


    All of a sudden my BIOS was not checking CD/DVD drives first, so that I couldn't put in a rescue disc. I tried to change this & ended up where I couldn't boot normally. I got a message to "press any key to boot from floppy". I have 2 CD/DVD drives & now I can't even see the 2nd one in my BIOS setup any more. Here is a picture of what I had changed it to:
    Reset BIOS so that it first checks CD/DVD drives, & then boots normal-image.png
    The option listed as Boot Option 2 & 5 no longer show up. When Boot Option 1 (P0 etc.) was set, I got the floppy drive message above. It got to the point that I couldn't boot to Windows. I went into the boot menu & selected override to P3: Samsung. Otherwise, I couldn't even boot.

    How can I change it so it checks my 2 CD drives & then boots regularly if no disc is in there?

    Thank you in advance!

    I would set it so it checks ONE DVD optical drive, THEN goes straight to booting Windows.

    When things start going wonky...having the comp able to boot from either of two optical drives will get messy.
    I have mine set to check ONE optical drive, and if nothing bootable is in there...boot straight to Windows.

    And my case can take 6 optical drives.

    There's not much else I can say. Last time I had an Intel board, CPUs were like 75Mhz.






    /edit

    You can hit F8 during boot, and choose any device you have to boot from.

    Here's my BIOS... it's not like yours.

    I have Boot override as well. I can just click on w/e I want to boot from.
    I wish I could be more help. :/

    Thank you for your quick reply. However, right now, the only optical drive that shows (the one that starts with P0: ) gives an error message about a floppy. I'm not sure whether I go into the BIOS or boot options or how to set them. I've done something though & don't know how to change it. I no longer see both my optical drives. This is what I see:

    Is there an adjustment I can make so that I recover both optical drives & have the override options? I would select the P0, but that now gives an error that I can't get out of.

    Try resetting the BIOS to defaults. (without the USB stick plugged in)

    Maybe that will make things more apparent? From what I saw in your manual, you're on the right Tab in the Bios.



    The only other thing I remember from way back... is don't set any drives to letter A: or B: in Windows..
    Maybe that's why something is coming up as a floppy?

    And definitely take out the USB stick. I just plugged one in to take a screenshot in the BIOS... then exited and I got a message saying there wasn't anything bootable on the USB stick.
    It's like the USB stick takes over somehow. It wasn't even on my boot priority list.

    It wasn't even plugged into the motherboard. It was plugged into the case, and the comp still tried to boot from it.

    My point is... that just having the USB stick plugged into any USB port, is probably messing up your boot order somehow.

    Thank you so much for your help & patience. I've had my optical drives set at A & B for some time without any problem. But I can't find any way to set it back to defaults.

    I set the BIOS like this:
    Reset BIOS so that it first checks CD/DVD drives, & then boots normal-image.png
    With that setup, I can put my Macrium Reflect rescue disc in & it will load. However, when I take it out & close Reflect, which starts the reboot process, I get the floppy error message.(The only reason the USB drive is in is so I can take a picture by pressing F12.) The only way I can boot to Windows is to set Boot Manager to priority 1, so I'm really confused as to how to correct this.

    To change the drive letters for the optical drive(s), go into Disk Management and right click on an optical drive and choose: Change drive letter.
    Then pick a letter like S. It'll give you a warning...just say yeah... do it anyway.
    Do the same for the other optical drive, make it drive letter T.

    That's pretty much it. You can change any drive letters in Disk Management except the C:\ drive.
    All you have to do is make sure the letter you want to change a drive TO... isn't already in use.


    Look at my Disk Management...

    Let's say I wanted to change the D: drive to E: but still keep all the drive letters in order.
    I'd have to start at the bottom of the list, and move them all down one letter.
    By the time I got to the top... E: would now be free to use.

    That's why I suggested S and T for the optical drives. That way they won't be in the way.
    Don't use A:, B:, or Z: They are all baked into Windows as letters for other things.


    On a side note... you can also right click any drive and choose properties, and change or add a text name to the drive, like I did with mine.

    Giving them names, makes keeping track of stuff... easier.

    Thank you again. I actually knew about Disk Management, but I've been fiddling with the BIOS so much that I can't think straight. I did change the optical drives to R & S.I also found that when I went to save my BIOS settings, I could choose to restore defaults. I had to choose Save & Exit & then there was an option to load defaults. They were:

    Of course, this takes me back to the original issue of not having the BIOS first check for an optical drive. So when I put a rescue disk in either optical drive & reboot, I boot straight to Windows.

    You still have that Flash drive hooked up.

    It looks like the priority you want, after you lose that flash drive, is...

    1. optical drive
    2. optical drive
    3. Boot Manager (Samsung 850 Pro)

    I know the flash drive is to save screen shots... but w/e a flash drive is hooked to the computer, the BIOS assumes you want to boot from it.



    And while you're poking around in the BIOS... on the Save & Exit tab...you need to learn these three things...

    Note what OI crossed out... don't do the things I crossed out.

    Above, the dark pic... see the yellow dots? When you click on those words, it'll look something like my BIOS screen below.
    You'll have eight slots to back up your BIOS.
    When you get everything working the way you want...SAVE the BIOS to one of the slots.

    Then if you ever need to "go back", you can just LOAD that profile you saved earlier.

    The other thing is the F8 key.

    When you first turn on the comp, or restart... just spam the F8 key a bit.
    That will take you to a pre boot screen that will list all your drives.
    You click on the one you want to boot to...and the comp will boot to that device.




    Here's my F8 pre-boot screen.

    I can just choose the optical drive and the comp will boot to the optical drive.
    No muss, no fuss.

    Yes... it would be great to have it check the optical drive automatically. But until you get it working, you can also use the F8 key.


    And.... as you probably know... "Enter Setup" means enter the BIOS. So you have that option too.
