    Hello thegod and welcome to Tenforums ,

    Give this a try...

    Choose Default Operating System to Load at Startup in Windows 10

    Change Boot Entry Display Order in Boot Menu at Startup in Windows this may be useful too. Then you can just hit enter. You can also change the default timeout to a smaller value.

    the problem is, i cant boot into my actual window drive in bios. my drive named "corsair mp510" boots into the linux OS i have installed, but i want to boot into the windows partion on said drive. it does not give me the option and only says the drive name.

    Are you using the Linux boot loader?

    here is a more detailed explanation of my problem:
    i attempt to load into my bootloader OR directly booting to my secondary drive.

    in the bootloader i only have the option to load into my secondary drive(the one running bcdboot) and cant boot into my main drive

    basically, my main drive has windows on it. but no way to boot into it without my secondary drive..... attempting to boot into it shows me my linux boot loader, which only shows me my secondary drive, which shows me bcdboot. lol

    i need to be able to boot into my main drive without the requirement of my secondary drive

    Hi,

    From your screenshot, It is very difficult to assess the situation. I assume your drives are all MBR and you could probably get out of it by deactivating Disk 1 and activating disk 2

    But since I don't know where your Linux or Windows are installed. I would not say if you will be able to boot "without relying on it"

    If you explain how you installed this setup and a little history on it, could make a great difference.

    Also Labelling Your Disks As "Linux", "Win10", "DATA", "Backup", "Programs" helps a lot in recovery consoles.

    Your best solution would be to disconnect all other drives, Install the one with Windows as drive 0, and Repair the boot process.

    Then unplug drive 0 and plug the drive with linux on port 1 and do a startup repair there too.

    After that you would be able to boot directly to Windows or use your MB boot menu to start any system you want.

    Always disconnect other drives when installing new OS.

    I agree with @MaloK post.

    Posting Disk Management with all drives showing would be beneficial too.

    so a little explaination:
    i have 3 drives in my pc, 2 of them only matter for this.
    my main drive has 2 partions, 1 has linux, the other has windows.
    my second drive has my OLD windows install, that i use to boot into my second drives window partion.
    i want to format my second drive, but i am then unable to boot into the windows partion, os-prober/update-grub ONLY detects my second drive's version of windows.
    the only way to access the second drive windows partion, is by using the first drives bcdboot.

    i can NOT lose any data on the main drive, all i need to be able to do is boot into it via my bootloader OR bios. i cant do that without the second drive's bcd at the moment.trying to change system partion. 2 windows installs, 1 in use.-screenshot_1.png

    "Your best solution would be to disconnect all other drives, Install the one with Windows as drive 0, and Repair the boot process."

    this would cause me to boot into grub/linux.

    Ok....

    Make disk 2 active shut down, remove disk 1 and boot. You will know right away.

    And it will not prevent you to go back instantly.
