What is EFI buying us exactly ? Probably the most obvious and necessary benefit is that EFI understands GPT which is needed for storage devices over 2TB (MBR cannot reach anything beyond the 2TB barrier). UEFI can actually directly load and run an operating system, like other bootloaders (such as U-Boot), instead of just loading the first LBA of a ...

From Wikipedia: The Unified Extensible Firmware Interface (UEFI) (pronounced as an initialism U-E-F-I or like "unify" without the n)* *Various pronunciations have existed for UEFI; according to the UK PC Pro Magazine, the following pronunciations are in use: "weffy" (PC Pro), "U-E-F-I" (Microsoft), "you-fee", and "you-ef-fee".

You can't have custom images for a bios boot screen.... The most you can do is enable the boot logo or disable it but customizing would never work. Also most mediums of storage wouldn't be available to the bios before post so no way to even store an image for this..

According to the unmissable comment from jay in the comments, I guess the answer is to set the jumpers correctly on the IDE drive. "Cable select" should just work, but if it doesn't try to set it to "Master" instead. If it still doesn't work, you may want to take a good look at the partitions on the drive using GParted or another partition tool to see if ...

To recover your WD drive do the following: Make sure your WD External Harddrive is switched on and connected to the PC or Laptop Swipe with your mouse to the top right or press Windows + S In the search windows, type Storage Spaces Select the Storage Spaces and then ...

Now I want to know, how the BIOS gets powered on eventhough the voltage from the CMOS battery is not sufficient. The voltage from the "CMOS battery" is only there to keep a tiny amount of CMOS memory, a type that uses extremely little power, from losing its contents, and to run the real-time clock (RTC). The battery power is not required to "power on" ...

Yes, an USB drive with no MBR can boot in UEFI mode: In addition to the standard PC disk partition scheme, which uses a master boot record (MBR), UEFI works with a new partitioning scheme: GUID Partition Table (GPT). GPT is free from many of the limitations of MBR.

Yes. It’s also not about GPT or MBR partitioning schemes. It just needs to be FAT32 (could work with other filesystems too, depending on what the actual UEFI implementation supports) and have the bootx64.efi file at the right location.

You can't. In desktop PCs with ATX power supply, some BIOSes allow you to wake up or start the computer from off state by pressing a key or key combination on the mouse/keyboard but I've never seen a laptop with that feature, and no BIOS allows you to press both a key on keyboard and power key too. If you want to reset you can simply hold down power button ...

This is normal. The logo is stored inside the UEFI firmware and it used during UEFI boot. On my Dell I can get rid of it by enabling the Option Load VGA Option ROM in the UEFI settings. This disables the GOP of UEFI.

You need to run the Dell on-board diagnostics. If you can keep the laptop booted up long enough, run the diagnostics by pressing F12 at the BIOS splash screen, then choose the Diagnostics startup option. The diagnostics will test the CPU, motherboard, memory, and other critical components of the laptop. After running an initial diagnostics test, taking ...

Here are some thoughts. I'm not familiar with your make of computer, and I'm also not familiar with what event led to these symptoms. Can you please give some more information about anything leading up to the laptop not booting up to an operating system? Has the laptop ever booted into an operating system? Are you attempting to install an operating system? ...

You didn't kill your computer, you just wiped out Windows. The recovery disk is intended to recover Windows that is installed, not to reinstall Windows from scratch. If your original Windows key is on a sticker on your computer, you could reinstall Windows from the generic iso. This is slightly different from what was installed on your computer. What was ...
