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?

@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.
- 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.
- 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;
- 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.
- 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;
- Check the Primary partition and left-click on the “Next” button;
- 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.
