UEFI mode is not detecting my usb flash drive.

Chauhan

Hey! I'm trying to install windows via my sandisk flash drive but UEFI mode is not detecting it.I have already made it bootable.
Although Legacy mode is successfully detecting my flash drive.I have also tried to move my flashdrive to first place in priority order(legacy mode) and then moved back to UEFI mode but nothing worked.
I'm also getting windows error : 0xc0000034

If you can enter the recovery mode then under "troubleshoot" you will find a command line option. If you can reach a command line try steps 3-5 here:

Hi,

If the above mentioned issue is not resolved then please understand that if the device comes with OEM operating system of Windows 10 and if you are trying to downgrade the operating system then it needs to done only by legacy mode but it does not work from UEFI. but if you are trying to change the operating system with the same as original then you no need to change the boot mode.
