Windows 10: Legacy boots usb fine but UEFI can't recognize it.

So i have a laptop with windows 10 And i downgraded it to windows 7 thus i change uefi to legacy but since drivers are not compatible with win7 i tried to clean install again in windows 10 using uefi but it cant be recognize unlike legacy. It always shows (no bootable device)

:)

 

Is it possible to install Windows 10 in UEFI mode using the original USB stick?

Same problem here. I bought windows 10 home on USB stick. USB stick is recognized in Legacy BIOS mode only. In UEFI mode isn't visible. I made my own bootable usb drive - I copied files from Microsoft’s drive and it works fine – Legacy and UEFI mode woking.

Why original USB stick not working in UEFI mode? (tested on PC and notebook – both UEFI capable)

USB Stick is useless in this form...

 

Intermittent Boot-up Problems Windows 10

I found that I was still in Legacy mode and changed to UEFI. There were two choices for UEFI and I wasn't sure which one to pick. After changing to UEFI, the only way I could boot was with the USB device in place. Without the USB, I was told there was
no boot device available. I had to revert to legacy in order to boot up at all.

 

You try change it to auto or change it back to legacy.
Or according to your statement, format the drive again.

 

How to change it to auto? I tried to format the drive when i run the win10 usb in legacy. I format it then quit the installation then change the legcy to uefi but still wont work

 

Also i clean install windows 7 and format hdd , so obviously i cant perform factory reset haha.

 

Is it booting from the thumb drive in UEFI Mode? How did you create your install media? Some devices will not install in UEFI mode if the thumb drive is formatted in NTFS.

 

BIOS settings.

 

I have down the iso from microsoft site, and i burnt it using rufus. I didn't change anything from rufus setting before burning the iso .. but as i remember i saw nfts somewhere there.

 

USB must be fat32 for UEFI install media

6. To Create Bootable UEFI USB Flash Drive for Installing Windows 10 with UEFI

 

I use diskpart, option 2 here, http://www.eightforums.com/tutorials...e-windows.html Doing it that way I can use that one thumb drive for both UEFI and legacy. Just swap the Windows 8 ISO for a Windows 10 ISO.

 

That's odd ... I get this when I click on your link

I have no idea what went wrong? I did an edit and the link looked correct there too. I replaced it with a new one anyway. *Confused
