PCUnlocker: Support 32-bit UEFI and 64-bit UEFI Boot

May 29th, 2014 by Admin

uefiUEFI (Unified Extensible Firmware Interface) is a standard firmware interface for PCs, designed to replace legacy BIOS (basic input/output system). Many new computers are shipping with UEFI firmware instead of standard BIOS. Most of UEFI-based computers come with 64-bit UEFI but there are also some Windows 8 tablets that use 32-bit UEFI, such as Dell Venue 8/11 Pro, Toshiba Encore, Acer Iconia W3/W4, Lenovo MIIX 2, Lenovo ThinkPad Tablet 2 and ASUS Transformer Book T100/T300.

However, there is a limitation on installing Windows on devices with UEFI firmware. A 32-bit UEFI firmware core must be used to install a 32-bit OS and likewise 64-bit UEFI for a 64-bit OS. It is possible to have support for both 32-bit and 64-bit UEFI in one BIOS, but it requires additional work and ROM space, so this may not be commonly implemented.

If you forgot Windows administrator password for a UEFI-based computer, you can reset it easily with PCUnlocker. Just make a PCUnlocker Live CD and you can then use it to reset lost Windows password on any computer with EFI/UEFI/BIOS firmware. If your computer doesn’t have an optical drive, you can use the freeware ISO2Disc to make a GPT bootable USB drive from PCUnlocker ISO image.

PCUnlocker is available in two version (UEFI 64-bit version and UEFI 32-bit version). You can purchase the full version or try the trial version before deciding on making a purchase.

How to Know If Your Computer Supports UEFI

July 1st, 2013 by Admin

One of the largest underlying changes to Windows 8 is the long-overdue shift from BIOS to UEFI. Secure Boot is one of the new features introduced by UEFI and it has received by far the most attention, as it prevents Linux distributions from being installed on Windows 8 machines. In this article we’re going to tell you a few methods to know if your computer supports UEFI.

The simple way to tell if you have UEFI boot mode or not is to watch Windows starting up. If you see the Windows logo when it boots, you are in old fashioned BIOS boot mode. However if you see your manufacturer or custom BIOS logo remaining whilst Windows starts you are in UEFI mode! In my Windows 8 Dell computer which comes with UEFI BIOS, every time I turn on the machine, it will display a Dell logo with the looping circles at the bottom.

dell-boot-screen

Another method is to use the MSInfo command. Press Windows + R key combination to bring up the Run box in Windows 8. Type the “MSInfo” command and press Enter. It will display all your system information and hardware configuration in detail. From the System Information window, you’ll see BIOS Mode listed as UEFI if your computer supports UEFI.

msinfo

If you’re still uncertain if your computer comes with UEFI BIOS, you can check out the Secure Boot option by booting your computer into BIOS. Try to go through all your BIOS settings to look for an option such as “Secure Boot”, “Secure Boot Control”, “Attempt Secure Boot”, etc. If you can find that option, your computer is using the latest UEFI BIOS.

How to Know If Your UEFI is 32-bit or 64-bit?

If your UEFI computer comes with Windows 8 64-bit pre-installed, it uses 64-bit UEFI firmware. If your UEFI computer comes with Windows 8 32-bit pre-installed, it uses 32-bit UEFI firmware.

While in UEFI mode, the Windows version must match the PC architecture. A 64-bit UEFI PC can only boot 64-bit versions of Windows. A 32-bit PC can only boot 32-bit versions of Windows. If you want to run a 32-bit Windows on a 64-bit UEFI PC, you need to change the boot mode from UEFI to Legacy/CSM and disable the Secure Boot option in BIOS. However, not all UEFI computers provide with the compatibility support module (CSM) that enables UEFI firmware to emulate a legacy BIOS.

How to Create A Bootable USB Drive for UEFI Computers

June 25th, 2013 by Admin

Nowadays, most of the new Windows 8 laptops, desktops or tablets use the UEFI replacement for the traditional BIOS, such as Surface Pro, Samsung Slate or other UEFI systems. The problem with UEFI-based computers is that they can’t boot from bootdisk with NTFS partition. UEFI system requires that your bootdisk resides on FAT32 partition.

Most USB burning programs will format your USB drive as NTFS, which includes the Microsoft Store Windows USB/DVD download tool. Luckily there is a free ISO burning software that lets you create a bootable USB with FAT32 file system only. It’s called ISO2Disc. But here I’m going to show you how to use the Command Prompt to create a bootable USB drive for UEFI computers.

How to Create A Bootable USB Drive for UEFI Computers?

  1. Open the Command Prompt with administrator privileges, then start the diskpart utility:
    diskpart.exe
  2. List all the disks and identify your USB drive:
    list disk
  3. Select the disk number that is your USB drive.
    select disk 1
  4. Remove all existing partitions:
    clean
  5. Convert the partition table from MBR to GPT:
    convert gpt
  6. Create a new partition, make it active and format as FAT32, then assign a drive letter:
    create partition primary
    select partition 1
    active
    format quick fs=fat32
    assign
  7. Type “exit” and press Enter to quit diskpart utility.

The final step is to copy all the files from your physical boot CD to the USB drive. For example, you can copy all files from either your Windows 8 installation DVD or ISO image to your USB drive. After that, you can use the USB drive to boot your UEFI computer and perform system repairing or installation for your own purpose.

If you still are unable to boot your UEFI computer from the USB drive, you may need to disable the Secure Boot option in the BIOS. In my Samsung Slate tablet PC, I have to disable the Secure Boot by following these steps:

  1. Press and hold Volume-Up and Volume-Down, then power up or reboot the slate. It should go into BIOS setup.
  2. In “Advanced Configuration”, change “Attempt Secure Boot” to Disabled.
  3. Press Volume-Up and Volume-Down to exit, then “Save Changes and Reset”.
  4. Power off the machine.
  5. Plugin USB drive to slate. Press and Hold Volume-Up button, then power up the machine. It should boot into USB drive now.
