Drives Missing in the bios boot options

[Kinnyr900]

I have another question when I reinstalled windows I went into the bios and in the boot mode section I chose just uefi not uefi legacy mode and now I just noticed this by the way when I went into my bios the boot section The only drive that I have listed in there is the windows boot manger all the other drives are gone not showing up there. Is that because I reinstalled windows from a usb stick with just uefi and not uefi/Legacy. So if I do another reinstall with uefi legacy support will I get all of my drives to show up there again. And are there any disadvantages to have the bios only show the bootmanger in the bios Under boot options And how can I tell in my bios or anywhere for that matter if My computer is using full uefi to boot into windows ?

Thank you so much for all your help!

when you set the bios to efi boot only the first hard drive is now the main boot device and the others are blocked out as boot devices. if you need to boot from a cd or usb stick you can use the f9 boot order overide to select the device you want to boot from. having your bios set the other way would let you boot from any device at boot. with windows now the bootable device is the drive with the system reserve partion on it.

The windows boot manager isn't even a drive it's the windows boot manger In your opinion is this the way I should have reinstalled windows I mean to just set the boot mode to uefi Only. When I had all the drives listed in the bios I still had to have the first boot device as the windows boot manger if chose my ssd samsung 850 pro which is the drive that windows is on windows would not boo,t it would give me a blue screen that says a device is unacessable or not available. And I would have to revert back to booting from the windows boot manager to get back into windows. So My question is. How can I tell if my computer is suing uefi to it's fullest and not gpt when it boots into windows. I don't have any special drivers that I downloaded or any firmware It came with the motherboard the uefi. And also On my c drive there is another partition that reads as fat32 and itr says 100mb for a capacity used space 28.8 mb free space 71.19 mb GPT,EFI and the status is system. Now the c drive is ntfs for a file system. 119.14 for a capacity.used space 25.97 gb free space 93.17gb this says it's gpt and the status is boot. Sop My question is how can I get rid of this second partition or not get rid of it but place it on the c drive so that it does not show up as a secnd partition and get my computer to boot in uefi mode iif it's not already. And how do I get it to allow me to boot straight from the ssd and not the windows boot manager?

Thanks so much!

You don't understand the relationship between the UEFI BIOS and GPT partitioning and the file system the disc is using. They are three separate things but must handshake correctly..The second smaller partition is the boot loader info AND is necessary to boot.

Okay but I tried connecting to my ssd in the boot override I clicked on it and I got a blue screen it said the disk was unacessable and I had to install by the boot manager that is the only device that is shown it's the only device I can boot into windows with. What I'am asking is how do I get rid of the boot manager and get all of my hrard drives to show up again in the bios and how do I get rid of the windows boot manager so I can boot straight into windows using my ssd as the first boot option. And how do I get windows to use uefi and not gpt? Do I have to reinstall windows 10 using uefi/legacy mode. Because for my particular bios I can choose either uefi, uefi/legacy which uses both or just legacy? The option that I chose in the bios just before I reinstalled windows 10 was just uefi mode and after I did that and got back into windows that's when I noticed that I could only boot from the windows boot manager in the bios and it was the only drive that was showing up if you want to call it a drive. So should I use the uefi/legacy option and reinstall again? You think after doing that, I will be able to boot into windows using the ssd and not the windows bootmanager?

O.K. Take the drive your trying to load the os on and format it in another machine using the NFTS file system. Partition it in disc management and convert it to GPT there.. Disconnecd all other drives cept the optical drive and reinstall it in the machine you want to use it in. Set the BIOS to UEFI. reset and then make sure the disc is recognized in the bios, Install the W10 OS. After that if the machine boots. shut down and install any secondary drives ya want to use. Ya might have to reset the boot order from the drive option and save,. Reboot and ya should be good.
