Solved UEFI Bootable USB Flash Drive

[forwinhelp]

USB Flash Drive has to be in GPT?

Hi there

NO

Creating a bootable UEFI drive is done by for example downloading a Live Linux distro on to a bootable USB drive. When the drive boots if the BIOS in the machine supports UEFI you'll usually (in the case of Linux distros) get TWO options - boot the UEFI OS or the regular one.

The same with Windows if you make a bootable USB from the Windows install ISO.

How to install Windows 7/8/10 64-bit in UEFI boot mode.

- Create a new virtual machine.

- Open the .vmx (virtual machine configuration) file of your virtual machine, add in:

firmware = "efi"













If you ever want to force VMware Player to enter the Boot Manager screen on next boot, add in:

bios.forceSetupOnce = "TRUE"

Note that bios.forceSetupOnce = "TRUE" will be automatically deleted in .vmx file after successful booting.



Here is info about UEFI Boot Mode (installing using the GPT partition style) and Legacy BIOS Boot Mode (installing using the MBR partition style): link

Hi there.

If the DVD is a Windows INSTALL ISO the relevant version of the OS will be loaded and booted up. You don't have to boot the DVD in UEFI mode --in fact it probably WON'T work anyway. Just in your computers BIOS enable LEGACY BOOT so the computer can boot an OS from an external device. If UEFI is enabled then the install will be the UEFI version (always assuming the target HDD is formatted with GPT and not MBR).

Note this is NOT the same as PROTECTED BOOT -- you need to disable that first or "external boots" won't work. I suspect that "Protected Boot" will disappear before too long anyway. UEFI is DIFFERENT -- nothing wrong with using it - and it does work even if protected boot is disabled too.

The word "try" really gives me the ceeps

 

[forwinhelp]

VirtualBox currently does not support booting of Windows guests using UEFI firmware.

You must use VMware Player.

Edit *.vmx configuration file, add in:

firmware = "efi"

If you ever want to force VMware Player to enter BIOS/EFI firmware on next boot, add in:

bios.forceSetupOnce = "TRUE"

I want to create UEFI Bootable DVD

As far as I know there isn't anything special that has to be done to a DVD (other than being bootable) as far as UEFI goes. Once you boot from it you should get two boot options for it, one UEFI and one normal.

 

[forwinhelp]

I will let you know if normal DVD iso works or you need to create special UEFI DVD/iso. Though I used special one. I will try with normal one later and update here.

This worked for me.

Copy all files from the Windows 8 DVD to a local folder eg. C:\Win8Media

oscdimg.exe -m -o -u2 -udfver102 -bootdata:2#p0,e,bE:\Win8Media\boot\etfsboot.com#pEF,e,bE:\Win8Media\efi\microsoft\boot\efisys.bin E:\Win8Media E:\win8pro-uefi.iso

I'll take your word for that, It's been ages since I last burned a DVD. I do all my installs from USB thumb drives. If I was going to install from a DVD I'd just use one of my Microsoft Windows ISO files.

What is oscdimg.exe?

What is oscdimg.exe?

Download Windows Assessment and Deployment Kit (Windows ADK) for Windows 8.1 Update from Official Microsoft Download Center

I have the toolkit. Looks like that directory is not in my path environment variable so not recognizable as a command.

Google gave me the info:

Oscdimg is a command-line tool for creating an image file (.iso) of a customized 32-bit or 64-bit version of Windows PE. You can then burn that .iso file to a CD-ROM or DVD-ROM. Oscdimg supports ISO 9660, Joliet, and Universal Disk Format (UDF) file systems.
