dell Efi USB Device boot failed

[DylanrHay]

Hi there

 

I have a Dell Inspiron 3531 and I installed Ubuntu 17.10 on it. I dont like it so I am trying to install my Windows 8.1 again from a USB stick. Everytime it tried to boot from the USB stick it says EFI USB Device boot failed. How do you fix this!!??

 

Thanks

Dylan ;-)

How you made USB stick?

[DylanrHay]

I used Rufus 2.18

use a diskpart clean, format the device in my computer or this pc (do this all from another windows pc)

use rufus UEFI mode with a 64 bit iso

make sure you have UEFI booting enabled, you should have 2 boot options for tyhe one USB

 

EG my sandisk extreme usb will have

 

Hard drive

CD drive

Sandisk Extreme

Sandisk extreme UEFI

as a last resort use a cd lol, uefi was designed for them if I am correct

What do you mean a diskpart clean?

open CMD as admin

type "Diskpart"

wait for it to load

Type "list disk"

make sure you notice which one is your usb, you pick the wrong thing here, you can fk the current pc BEWARE

Pick the number associated with the usb drive, type "sel disk 3" where in my case 3 is my pendrive

type clean, this will remove ALL partitions from the drive,

 

remove and replug the usb and format it in my computer/this pc

 

 

UNDER NO CIRCUMSTANCE SELECT YOUR LARGE HARD DRIVES, in my case disks 0,1 and 2

Ok. In rufus do I select 'MBR partition scheme for BIOS or UEFI-CSM'?

thats what I do, there is also a uefi specific one that should work but I just use the one you said

 

Make sure your partition is also sub 8gb

What do you mean by sub 8GB. This is what I am doing now.

that should be fine, uefi has some issues when using flash drives that are 16gb or higher, but since yours is 4GB it is fine

 

If this doesnt work you may need to convert it from NTFS to fat32, give it a try first

When I go into my boot options it has

 

UEFI Boot:

hdd1-ubuntu

efi usb device efi dvd/cdrom

efi network

 

Other Options:

Diagnostics

Enter Setup

Peripheral Device Setting (OPROM setting)

Change boot mode setting

 

It also says 'Boot mode is set to UEFI; Secure boot: ON'

 

I have tried booting into the usb but it wont work it just says 'EFI USB Device boot failed'

 

Should i change the ubs to fat32?

Try turning Boot mode:UEFI to the other option, should be something like UEFI and legacy or UEFI and cmos/csm

 

you do not HAVE to use uefi, the old method which is easier in most cases is still present.

 

After trying the above, insert the usb into a working windows computer, press the start button, type "partition" and click "create or format hard disk partitions", this brings the windows partition wizard, 

Identify the row for your USB, say for example my usb is 8GB, the row will say 8GB at the start, it should have one partition on it, marked as active and primary, (or one of the two).

 

After making the Windows usb, open it and copy ALL files in the USB to a folder somewhere, eg on your desktop. Go onto my computer/ThisPC and right click your USB, format it by clicking "default allocation size" and then change the dropdown to FAT32. Make sure quick format is selected else you will wait a few days for this.

 

Copy all the files back, making certain that if the partition program said it was "active" before you formatted it, then it is reset to active, the same with it saying it is "Primary".
