Solved :) The cause seems to be a strange feature in the UEFI implementation, which can also be seen in the Open Source TianoCore implementation: https://github.com/tianocore/edk2/blob/master/IntelFrameworkModulePkg/Library/GenericBdsLib/BdsMisc.c#L1425 I ultimately found it after diffing my EFI variable dumps after the last 21MB "loss" and finding ...

Here is what i did with help from nix-dev mailing list. Initial setup MacBook 5,1 (2008) with Mac OS 10.9 and hard drive partitioned as follows: a) 200MB EFI System Partition labelled "EFI". b) Two partitions used by Mac OS (10.9). c) Two empty ext4 partitions labelled "nixos" and "home", and a Linux Swap partition labelled "swap". Here is my ...

No, your MBR is not working, but that's fine, because your Windows never used it in the first place. Your computer has the new UEFI firmware instead of BIOS, and it does not look for boot code in the MBR anymore – instead, it looks for the bootloader file in an "EFI system partition", and the firmware keeps a list of installed operating systems with ...

Power-on Self Test or POST is part of the part of the preboot sequence. It tests for common hardware faults. Generally the results of the POST are indicated by audible beeps. Some more advanced hardware, such as motherboards marketed to overclockers, may have a digital readout that displays a code.

The major advantages that UEFI provides are: 1. Better disk support: UEFI supports GPT (GUID Partitioned Table), which adds support for very large hard drives (e.g. those in excess of 2TB.). BIOS uses MBR, which had a size limitation of 2TB because of 32bit tables. UEFI has 64bit tables allowing the boot devices to be larger than 2TB. This has a lot of ...

The manual exists on Asus' support site and it contains the beep codes on page 2-16 ("Chapter 2: Getting Started"):

It's possible, and it's very frequently done with both external USB sticks and internal drives. Regarding partition table types: BIOS normally doesn't need any partition table. It is only interested in the bootstrap code part that is the first 440 bytes of your MBR. (Although there are exceptions. Some BIOS implementations actually do break if they cannot ...

Google searches turned up tips like "you have to boot the DVD drive in UEFI mode to install OS on UEFI", etc. This made me believe that I have to convert my USB drive to GPT just to install an OS on an UEFI machine. <…> Why does the installer say it's impossible to install a UEFI-booted OS from a MBR-based USB drive? Can't it create ...

These are in fact 2 questions in one, so here are my answers: UEFI offers more flexibility in boot and device management in a system, it allows the use of GPT disks that remove the limit of 4 primary hard drive partitions, allows the choice of operating system to be booted from the firmware, enables the use of signed bootloaders to improve protection ...

UEFI is perfectly capable of booting BIOS-bootable operating systems, using the so called “Compatibility Support Module” (CSM), which emulates all the necessary stuff. And no, you cannot simply flash whatever you like. The firmware/BIOS is created specifically for your device. Unless the manufacturer provides a legacy BIOS firmware (he won’t), you’re stuck ...

Your system has a UEFI firmware. Because of this, Windows requires you to format your hard drive as a GPT disk instead of an MBR disk (which you have). GPT disks do not have the concept of an "Active" partition the way MBR disks do. That's why the option is grayed out. In a BIOS world with MBR disks, the computer simply boots to whatever partition has the ...

That sounds like your CMOS battery is dead. This problem should be completely resolved simply by replacing the cmos battery. I think this because of the messages you get on startup. The behavior is weird, but then again, I've seen dead CMOS batteries do the strangest things (like preventing a computer from shutting down)

Assuming you don't have an EFI firmware, I see a number of options: Ditch the computer and buy another one. Return your new disk (or use it somewhere else) and buy a 2TB model instead. If the computer supports two disks, use a sub-2TB disk for the Windows boot disk and use the 3TB disk (with GPT) for data. Note that you can probably get a kit to put a disk ...

This problem is resolved in my 10 years old HP desktop (4 cores), with drive: 3TB Western Digital Green, but it should be the same with Seagate too. I added the solution to this blog: Post Anything Here. In a nutshell you need 2 things to do: to install the Intel RAID driver (free). to use a good tool for extending the partition to the maximum size, ...

Big thanks to wzyboy. I faced with this problem when tried to install Windows 2012 to Dell PowerEdge 2950 with 6Tb RAID. It hasn't UEFI. I carried out some experiments. First I created 32Mb virtual HDD, as wzyboy said, and simply copied all stuff from Microsoft reserved partition. Windows was started normally. But with this solution, Hyper-V service unable ...

The latest version of Rufus allows seamless UEFI boot from an NTFS partition. If you select a Windows installation ISO, set the partition scheme to GPT partition scheme for UEFI computers and also set the file system to NTFS, Rufus will add everything required to allow booting NTFS partition from an UEFI system. Outside of using Windows installation media, ...

First, note that malware affects the OS, not the BIOS itself (because there is no value in controlling a BIOS). if someone is attempting to attack the BIOS, their real goal is to attack the OS that that BIOS will boot. Rootkits and other boot time exploits are designed to attack the OS by affecting how it gets booted. Traditionally BIOS and firmware code ...

You need to split the 350MB MBR boot partition into the System and Reserved partitions used by the Windows GPT boot system. Based on instructions I wrote last time I did this process: Load a command prompt from the DVD (Repair Your Computer -> Troubleshoot -> Advanced options -> Command prompt) diskpart select disk 0 list partition # To verify layout ...

You should be able to install Windows 8 or 8.1 with a UEFI-bootable pendrive: Format it to FAT32. Copy all files from a Windows ISO to the pendrive. This will make the pendrive bootable for UEFI. Then you can choose to reboot from pendrive. (this option is visible on the last photo) (I'm putting it here as a real answer, previously suggested in ...

After 1 year I came across the same problem again. Luckily this time I found a solution. In order to add an OsLoader in windows Boot-Manager which loads non-Windows UEFI images you need to manually edit BCD registry. In RegEdit there is a key named "HKEY_LOCAL_MACHINE\BCD00000000" - which is loaded from Windows EFI System-Partition and editing it's subkeys ...

You can install Windows on it with your non-UEFI computer, but it will only let you use the first 2 TiB (slightly more than a "2 TB" disk). Windows will not let you create partitions that extend into, or start in, the region beyond the 2 TiB point. So in your example you would not be able to create your third partition (1.5 TB). ( The reason is that MBR ...

I have read that in order to boot Linux with the 32-bit UEFI, you can swap out the standard 64-bit UEFI GRUB with the 32-bit one from a different distribution and it'll be able to work on the Stream 7, so maybe a similar procedure (swapping the 64-bit UEFI bootmgr with the 32-bit one and reconfiguring the entries to match your installation) might work to get ...

Another idea : Sometimes the problem is with the power supply. There are two cases : The secondary hard disk is connected to a power cable which is shared with another device. If the other device draws a varying amount of current, it might not let the disk start up fast enough to be counted as up and running by Windows. The allowed startup times vary ...

Insufficient power on startup. Possible as ODD usually requires more power to work, but less or same while spinning up as HDD. But make sure - what is the nominal power consumption for the hdd in the caddy? Usual are 0.5 A/1.0 peak for hdd. Try disabling all devices - wifi for example. LAN, especially if configured wit network boot (PXE).. I would rule this ...

The UEFI Shell is a regular .efi program, which you can download. Store it at \SHELLX64.EFI or a similar path on the EFI filesystem, and add it to the UEFI boot manager the usual way.

As far as I understand, I can install one Windows system on each drive, because Windows need to create an EFI boot partition (and an MSR, whatever that is). A second installation will refuse to install if there is already an EFI boot partition. That shouldn't be the reason. It is quite normal to share a single EFI system partition across several ...

After my initial bootrec.exe attempt didn't detect any Windows installation, I dug further into Microsoft's documentation. I booted into RE again and went to the command line to load diskpart: > diskpart Selected the disk: DISKPART> list disk DISKPART> select disk 0 Selected the partition called "SYSTEM_DRV" (FAT32 filesystem) and assigned it ...

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". It is also mentioned ...

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..
