    Windows built-in reset is extremely unreliable.

    When you get into Windows, look in disk management. If you see an EFI System partition, then it is UEFI.

    The likely reason you didn't boot into UEFI mode from the USB flash drive is because you didn't go through all the steps required to make Rufus create a flash drive compatible with UEFI - which happens A LOT!

    You really only need UEFI if your drive is over 2TB in size or you want more than 4 primary partitions.

    Okay windows is working. But now my problem is when I restart the computer, for some reason it boots into the dell supportassit and says no bootable devices. But if I put legacy support and go to f12 and boot from hard drive my computer boots up. How do I fix this?

    You should be able to go into bios settings and set the legacy mode and the hard drive as the defaults.

    I'm willing to bet your Windows 10 USB flash drive is formatted as NTFS and not with FAT32 which is required for UEFI.

    Blah now i mgetting this error when using legacy and making the hard drive the first device.

    File : \boot\bcd
    status: 0xc000000f
    info: The boot config data for your pc is missing or contains errors.

    And you are right. The usb is in ntfs not fat32. I thought rufus would do everything on its on.

    Are you sure your hard drive is not failing?

    If you want to try UEFI mode, prepare a bootable USB flash drive like this:
    Create a Bootable USB Flash Drive

    Make sure at step 9 to use FAT32 (see the Important box below the step):
    9. To format the partition, type format fs=fat32 quick, and then click ENTER

    For step 12, mount the Windows 10 ISO file and just copy all the files and folders from the mounted ISO file to the USB flash drive. You should now (typo) be able to boot the USB flash drive in UEFI mode (and it will also work on legacy BIOS systems too).

    When you get to the screen with the list of partitions on the drive, do like you did before, but this time add one command:

    diskpart
    select disk 0
    clean
    convert gpt
    exit
    exit

    Then refresh, select the unallocated space and click next.

    That should give you a UEFI install. But it does sound like you might have a HDD failure going on.

    I'm currently using the windows media creation tool and downloading a bootable usb drive for my laptop. This would be sufficient right and UEFI mode should work?

    Don't think its my ssd. Cause I managed to boot into the desktop, mess around with the files and folders. Its just each time I reboot it goes into the dell supportassit and shows no bootable devices. I then went to disk management and made my C drive the active one (with the os, boot, etc.)) I will try your method after trying the windows media tool.

    Yes, allowing the Media Creation Tool to create the USB flash drive for you will give you a flash drive that is bootable both in UEFI mode and legacy BIOS mode. It's just a little bit slower than the manual method. Plan on it taking 1/2 hour to 45 minutes.

    UEFI booting does not require a partition to be set as active. For the internal HDD/SSD it does require a FAT32 primary partition set as the EFI System partition type. To boot from a USB flash drive, UEFI requires the flash drive to be formatted in FAT32, but does not have to be set to the EFI System partition type. When you try the install again make sure to redo the commands and add the addition convert gpt command:

    diskpart
    select disk 0
    clean
    convert gpt
    exit
    exit

    Thank you very much dude. I got my laptop back. The problem was NFTS. Ah wish I found out earlier lol. Oh well I managed to back up my files using the notepad in cmd. Looks the problem was my boot partition got corrupted when I restarted. Hopefully this doesn't happen again. Not liking windows 10 much to be honest, but anyways I appreciate the help. Thank you again!

    Glad it worked for you! Rufus has caused a lot of headaches for a lot of people. The first question I ask any more when someone says, "I tried to use a USB flash drive to install Windows with UEFI, but...." is "I'll bet you used Rufus to create it, didn't you?"
