Reboot and Select proper Boot device error

[parikh]

I am trying to boot from usb to have a clean install of Windows 10 but when system boot in through usb it says "reboot and select proper boot device".
Boot priority is set to usb.
Any ideas how to solve it.

Specs
Dell Inspiron 15 3542

Windows 10 pro
4gb ram

If you're set to boot from USB, sounds like the USB isn't 'bootable'.

Did you buy this USB? Or did you put the OS onto USB? If you did it, how did you go about it?
Did you "mount an ISO", or did you just drag & drop onto a USB drive?

 

[fredfinks]

is it a usb thumb drive or a usb hard disk? Ive heard of hard drives not being as compatible as regular thumb drives. Also some thumb drives like sandisk extreme 64gb or extreme pro also not working. (they running some advanced firmware stuff to attain top speeds)

A regular usb 3 thumb drive like the sandisk ultra is the go.
If its is a regular thubmdrive then id contact Dell

Also, did you use MS's content tool on win10 page to create the USB win10 installation?

Hi there parikh,

Have you used some software in order to make this USB flash drive bootable?
In case you haven't, you need to do that.
In case you have done that, you can reformat it and try it again. If the issue persists, you can try the flash drive on another system and see if it will work over there.

Edit - I guess I was a little late. 😀

Hope this will help,

Startover
remove any partitions & formart the usb with NTFS
google 'download win 10' top result is microsfts website. use the creation tool to make the USB win 10. Download is about 3-4GB

Rufus formatted usb with fat32.
I am using the iso downloaded from microsoft website

fat32 and GPT from Rufus shoud work (Rufus is a good tool, so I don't think the issue arose from there).

In your BIOS, do you have an option to enable legacy support? Try enabling that and boot from the USB again.

 

[fredfinks]

remove it. remove any partitions and format with ntfs.
Windows tool does it all and it works.

Rufus is just adding a spanner into the works.

after disabling secure boot and enabling legacy support in bios i got option to boot with usb But than this hurdle came up.

Sorry, which hurdle?

It's been suggested you try NTFS (and use Windows media creation). It wouldn't hurt, although you already have the ISO downloaded, Iwould just use Rufus again and format to NTFS instead.

It'll be hit or miss when any media creation (Windows "authorized" or otherwise), but I've personally never had any issues with Rufus.

 

[parikh]

So do i format with ntfs or fat32

 

[Barty1884]

I would try NTFS.

 

[parikh]

I would try NTFS.

i will try this - bootable usb with rufus choosing ntfs and gpt partition scheme for uefi

 

[parikh]

Didn't work.
Getting same message again.
Edit - what if I start windows 10 installation setup from windows itself.
Will I get a option to format drive?

 

[Barty1884]

I don't believe so, I think it will format as needed. Not 100% sure on that though.
