About UEFI Boot

Why do so many people want to create a UEFI boot USB? In order to create a UEFI bootable USB successfully, it is necessary to figure out the following 2 questions first.

What Is UEFI

UEFI (Unified Extensible Firmware Interface) is known as a motherboard firmware interface for computers. It serves as a “middleman” between your computer’s firmware and the operating system. With UEFI boot mode, your computer can initialize the hardware components and boot the OS stored on the hard disk.

In recent years, UEFI boot mode seems to be the successor to the BIOS. More and more users tend to boot their computer in UEFI mode. This is because the UEFI mode breaks many limitations of BIOS mode, including the restrictions on the size of hard drive, booting process, number of partitions, and security.

In a word, UEFI boasts more advanced features compared with BIOS. Here we summarize them as follows:

Tip: If you want to know more details about UEFI vs BIOS, you can read this post “UEFI vs. BIOS – What’s the Differences and Which One Is Better”.
  • UEFI allows users to handle a storage device that is larger than 2TB, while the old legacy BIOS cannot handle so large d
  • With UEFI boot mode, you can create more than 4 primary partitions on a GPT disk.
  • UEFI supports secure startup. It is capable of checking the validity of the operating system to prevent malware from tampering the startup process.
  • UEFI firmware supports various optimization and enhancement, which can help your system boot more quickly than it could before.
  • UEFI supports both 32-bit and 64-bit architectures, which helps the computer use more RAM to handle a more complicated process than BIOS.
  • Under the UEFI mode, the computer supports networking function that can help remote troubleshooting and UEFI configuration.
  • UEFI has much more setup menus and simpler graphical user interface than legacy BIOS.

What Support UEFI Boot Mode

UEFI has lots of advantages over BIOS, but not all computers and devices are supported. In order to boot from USB in UEFI mode successfully, the hardware on your hard disk must support UEFI. One of the most important things is to make sure that your system disk is GPT form. If not, you have to convert MBR to GPT disk first.

If your hardware doesn’t support the UEFI firmware, you need to purchase a new one that supports and includes UEFI.

Now, you may have an overall understanding of UEFI boot mode. Let’s see how to create a Windows 10 UEFI boot stick. Please keep reading the following part carefully.

How to Create a UEFI Bootable USB

How to create a UEFI boot USB? Before starting the following steps, you need to prepare a USB flash drive with 8GB space at least.

UEFI boot mode is a type of boot mode that can run on the top of PC’s advanced firmware. Compared with the old legacy BIOS, UEFI has many distinct advantages such as faster booting process, more primary partition, and more secure startup.

To enable the UEFI boot mode, you need to access the BIOS Setup utility and then operate further. Here’s how:

  1. Press F10 and ESC (or Delete) keys when booting your computer to open the BIOS Setup utility.
  2. Go to the Boot tab and select the UEFI/BIOS Boot Mode by using the arrow keys, and press Enter.
  3. Select the UEFI Boot Mode by pressing the up and down arrow keys and press Enter.
  4. Press F10 keys to save the changes.
Since the EFI partition is a system and protective part on your hard drive, you can’t delete it in Disk Management. You need to convert it to a basic data partition using Diskpart and delete it. Alternatively, you can use professional software to delete EFI partition.

You need to prepare a Windows 10 bootable USB and follow the steps:

  1. Connect the USB drive to your computer.
  2. Press the appropriate key to enter the BIOS menu.
  3. Select the USB drive as the first boot order and save the change.

ACCES has VIs for LabVIEW 5 through 7, and 8.5, for most of our products, and USB boards have VIs demonstrating use in LabVIEW 8.5 through 2013. You can find the drivers for LabVIEW 5 through 7 in the /Drivers/LabVIEW directory on the Software Master CD. The LabVIEW 8.5+ drivers are available in the /Drivers/LabVIEW 8.5+ directory on the CD, and on the products' pages, both in the Manuals / Software tab, and in the navigation column to the left.

For your convenience, the two major LabVIEW packages are available here:

  • USB devices (other than serial ports)
  • Register-based cards (other than serial ports). This includes ISA, PC/104, PCI, PCI Express, and all related devices with I/O register address ranges.
  • Serial devices are supported directly by the Operating System and LabVIEW itself.

Supported Legacy Versions

  • 7.9 Driver Package

    This is primarily useful for USB products. The later USB drivers are mainly not a bugfix, but exist to add 64-bit Windows support. Further, it can be tricky to move from 7.x to 8.x or 9.x. So, you can continue using 7.x drivers via this package, which does include any bugfixes.

    Please note: ACCES USB devices invented after January 2001 are not supported by this package. (contact us if you need support added. We're here to help you succeed.)
  • 8.10 Driver Package

    This is the oldest supported driver with 64-bit support. Notably, USB products use Microsoft WinUSB.dll in this version, instead of CyUSB.dll (in the 9.x drivers), or CyUSB3.dll (in the 10.x, current, driver package)

  • 9.63 Driver Package

    This is the most recent driver using CyUSB to interface to USB devices (the current '10.x' drivers use CyUSB3 instead). Some customers have reported problems installing the 10.x drivers on some Windows XP systems: the 9.63 Driver Package should be used in those situations.

Datasheets / Manuals

To find your updated manual and/or datasheet, please navigate to the specific product page (starting with the product category, in the left NAV bar).

The manuals and datasheets are listed on each product's page, both in the 'Manuals / Software' tab, and in the navigation column to the left.
