trying to install windows 10 with bootable usb (only for UEFI)

Microsoft Windows 10 (64-bit)

i have downloaded windows 10 (1909) iso, and using rufus, created a bootable usb, with GPT -> UEFI and usb format is FAT32.

When i am trying to boot from usb, i am getting error, "boot device not detected". If i try to boot in legacy mode, then the error is, "convert to MBR".

Also, i tried mbr2gpt, in a preinstalled windows 10 home, the command runs successfully, but when i shutdown my laptop, and restart in secure boot mode, i get error, "boot device not found". Also, in secure boot mode, os manager shows no option.

How could i install windows 10 in UEFI only mode?

How could i resolve boot device not found error, after successfully converting MBR to GPT, using mbr2gpt?

H/W -> hp notebook 2000 2121tu, bios version F.39, factory os win 7 home

@misragaurav24 Welcome to HP Community!


  • Have you tried with the bootable USB NTFS format?
  • Please let me know how did you download windows 10 ISO.

I would suggest you try to perform with cloud recovery.


Please follow the below steps to install the Windows 10 using UEFI.


  1. You need to get the official DVD of Windows 10. If you don’t have a DVD drive on your computer, then you have to create a Windows 10 bootable UEFI USB drive.
    Note: You don’t know how to create a bootable UEFI USB drive? Check out this amazing guide and learn how to do it like a pro.
  2. Change the boot order in your UEFI system:
    • You need to go to the login screen;
    • Left-click on the “Shutdown” button;
    • Hold the “Shift” key and click on the “Restart” feature; if the Shift key doesn’t work, take a look at this simple guide to solve the issue.
    • A sub-menu will open. Left-click on the “Troubleshoot” feature;
    • Left-click on the “Advanced options” feature;
    • Left-click on the “UEFI Firmware Settings”;
    • Left-click on the “Restart” button;
    • After the restart, the computer will enter in UEFI mode (the interface is similar with the well known BIOS);
    • Navigate to “Boot” tab and enable the “Launch CSM” feature;
    • Go to the “Security” tab and disable the “Secure boot control” feature;
    • Before you exit the UEFI mode, you need to save changes;
    • The system will restart. Please insert the bootable USB drive or the DVD into the CD/DVD drive;
    • Enter again in the UEFI mode. In the “Boot” tab you will see the Windows 10 bootable drive;
    • Left-click on the bootable drive and enter Windows Setup;
  3. When Windows Setup starts, you will need to reformat the hard drive using the GPT partition table; if you don’t know how to do that, follow the easy steps in this article and get it done in no time.
  4. After formatting, click the “Next” button and you will get the following partitions:
    • Drive 0 Partition 1: Recovery –type Recovery;
    • Drive 0 Partition 2: System- this is an EFI partition that contains the core OS files, which are required to boot the operating system;
    • Drive 0 Partition 3: MSR- it is a partition that reserves space on each hard drive for Windows internal use;
    • Drive 0 Partition 4: Primary- this is the partition where all users data and Windows will be stored;
  5. Check the Primary partition and left-click on the “Next” button;
  6. Follow the setup wizard in order to install a fresh copy of Windows 10;


Please refer to the following link to troubleshoot the boot device not found.
