Windows 10: UEFI will not boot USB but all looks ok with the disk

Hello,
Need a little bit of help please. I have a HP Pavilion laptop running windows 10 Home 64 bit. It has UEFI boot.

I'm rebuilding it so used the Windows media creation tool to create a 64 bit windows boot disk (FAT32 formatted). When I go to the advanced boot options in Windows and select to restart for UEFI, in the menu if I select to restart using 'USB (UEFI)' it just gives me an error message. I then repeated but went to troubleshooting, went into the uefi bios and changed the bios order to be my usb first and on rebooting it just skipped it and went straight to Windows.

I created the boot disk fine, here is the basic structure and any help would be appreciated.

Thanks.

Install Windows 10 using UEFI bootable USB thumb drive

You need to go into you system bios and select allow uefi usb drive. Then add the UEFI usb drive to the boot menu

better way to partition aand create an bootable usb.

For the UEFI system, we can use these steps to create the bootable USB:

1.Locate a 4GB or larger USB flash drive

2.Open Diskpart and run the following command cmd admin type diskpart

• Type DiskPart in the command prompt.
• Type "List Disk” (make note of the disk number of the target USB drive).
• Type "Select Disk X”, where X is the target USB drive noted in step 4.
• Type "Clean”.
• Type "Create Partition Primary”.
• Type "format FS=fat32 quick”.
• Type "Active”.
• Type "Assign".
• Type "Exit".

Copy your ISO files to the drive and reboot

never use UEFI it better to repartition and remove UEFI go with legacy bois

 

Unsupported disk layout for UEFI firmware

Yes. Just download the Media Creation Tool and it will let you download an ISO file for the current version of Windows 10 (version 1709, build 16299.15). You can also have the Tool directly create a bootable USB stick with version 1709 of Windows on it.
If you already have this ISO file, a utility called Rufus can be used to create a bootable USB stick (8GB minimum size thumb drive required). http://rufus.akeo.ie

The steps to fix things will be:

• first create the UEFI-bootable USB stick (it will have a FAT32 format, rather than NTFS) using Rufus or Media Creation Tool
• Restart the computer and tap F2 to enter BIOS. Switch to UEFI mode. Leave Secure Boot disabled for now if that is an option.
• Exit and it will restart with the bootable thumb drive inserted. This time try tapping F12 which usually gives a boot menu. The USB should show up in the list, if it has been created right for UEFI.
• Once Windows Setup loads the first screen, use SHIFT-F10 to get a Command Prompt window.
• Now we can try to run MBR2GPT to convert the disk.
• First, MBR2GPT can validate that conversion is possible:
  • mbr2gpt /validate
  • assuming it validates OK:
    • mbr2gpt /convert
• Type exit to return to the Windows setup screen or just close the Command Prompt window.
• Cancel Windows setup by closing the setup window and let the computer restart to your existing Windows build 10240
• Once back in Windows, your disk should now be capable of upgrading to build 1709.
• Version 1803 of Windows 10 will be released this month or in April. If you want to wait to upgrade directly to that, it would be fine to do that. Meanwhile, you are now running in UEFI mode. There is a chance that you might be auto-upgraded
  by Windows Update to version 1709 anyway, so upgrading now is fine too.
• To upgrade now, from within Windows run setup.exe from your mounted ISO file or USB stick. Do not boot from the install media to upgrade.
• You can also now tap F2 during boot to enter BIOS and enable Secure Boot

 

Installing windows off of a USB stick

Step By Step from vista:
From admin cmd prompt

1. diskpart
1a. list disk
2. select disk 1 (replace 1 with your usb drive)
3. clean
4. create partition primary
5. select partition 1 (replace 1 with your usb drive)
6. active
7. format fs=fat32
8. assign
9. exit

Copy Windows Vista's DVD ROM content to the Flash Drive

xcopy d:\*.* /s/e/f e:\ (d being your vista cd and e being your usb stick)

And that's it, boot off your usb disk
