Windows 10: How to boot from USB without entering BIOS or UEFI Settings and boot menu?

Hi, as the title says. I made a bootable usb and I want to boot from it, but however I do not wanna go to UEFI Settings or BIOS or even the boot menu because there’s something I feel wrong about them, oh and also another question, can I use the bootable USB I just created today like the next day or like the next 2 days or is it not recommended?

BIOS / UEFI - can't USB boot

don't have problems booting here from USB but my bios/setup makes things simple with settings to allow UEFI, USB, or both with the option of UEFI first choice. the only time I cant boot USB is when windows has shut down or restarted with the power options
doing the fast startup mode. Then it seems to want to bypass access to bios but will still access my F12 boot select menu yet the usb boot will fail.

 

how to enter the boot menu when update from BIOS Legacy to UEFI

Hello every one! I have windows 7 laptop (HP elitebook 8470p), I upgraded to windows 10, and change from bios legacy to UEFI, when in Legacy I can press ESC to enter menu boot, but in UEFI I need enter windows 10 and shift + restart to enter it. So, if
one day my windows fail to start, how to enter boot menu to choose USB drive to reinstall windows?

When a MBR hard disk is converted to GPT, if you can't get into the system, it's usually due to incorrect BIOS settings or no UEFI boot. Here are the steps to solve this problem:

1. Enter PE system: Use a USB flash drive to boot and enter the PE system (pre-installation environment) to make sure the data is normal.
   
2. Check the BIOS settings:
   
   • Make sure UEFI boot is set in BIOS.
     
   • If the BIOS is set to UEFI boot, but the partition is still MBR partition, you need to modify the BIOS settings to match the hard disk partition mode and boot mode.
     
3. Use a PE tool that supports UEFI: Make sure the PE tool you use supports UEFI repair boot.
   
4. Create an EFI system partition:
   
   • In PE system, open "Disk Management", find the SSD (usually labeled as "Disk 1"), right-click and select "Compress Volume" to compress about 500MB of space.
     
   • Open a command prompt, type `diskpart` and enter.
     
   • Use the `select disk` command to select the SSD.
     
   • Use the `create partition efi` command to create the EFI system partition.
     
   • Format the EFI partition using the `format fs=fat quick` command.
     
   • Use the `assign` command to assign a drive letter to the EFI partition.
     
5. Bootstrap Repair:
   
   • In a command prompt window, type `bcdboot x:\windows /s y: /f uefi`, where `x` is the drive letter where the system is located in the SSD and `y` is the drive letter of the EFI partition.
     

Hope the above information can help you
