Similar thing happened to me this article pointed me out to the issue: http://twomorecents.com/cant-boot-linux-windows-boot-loader-has-taken-over/

There should be primary (main) GUID Partition Table at the beginning and secondary (backup) at the end of the raw file created by dd. Truncating the file destroys secondary one. There is a way to fix it. Let's start with untruncated file with free space at the end. Run gdisk -l myfile.raw. Notice logical sector size (512B probably). Find maximal end sector ...

The Linux kernel since version 3.8 abstracts UEFI variable storage as efivarfs. Mounting efivarfs If mount | grep '^efivarfs' doesn't return anything, you can mount efivarfs using this command: mount -t efivarfs efivarfs /sys/firmware/efi/efivars Now, you can browse /sys/firmware/efi/efivars to see if any variables stand out. Sorting UEFI variables by ...

The kernel parameters are (or should be) shown; it's just that they're converted to UTF-16 when you create the entry and then shown in two-character form, with "." characters between entries, when you use efibootmgr -v. For instance: $ sudo efibootmgr -d /dev/sda -p 1 -c -L "Arch Linux" -l /vmlinuz-linux -u "root=/dev/sda2 rw initrd=/initramfs-linux.img" ...

I know this is quite a while after and you might have found a solution but for the record, I'll post an answer. ALthough you cannot boot a GPT in BIOS bios, you can change the USB to a MBR partition table, currently it is GPT. NOTE - I believe promoting software is against rules, but there is no other way for me to post a solution, these software are ...

I've already found the answer myself, but thanks anyways for trying to help. In the help menu of the Gigabyte F2 BIOS, there was a message that said that the + and - buttons could also be used to navigate between option. I tried doing this with the system memory multiplier, and I finally got the result I wanted. I could select any common clock setting to ...

I believe the timing setting you are after will be available when you disable the "Auto" mode on the "Memory Timing Mode" setting. I've not seen your particular firmware interface, but I have seen quite a few that hide these settings while "Auto" is enabled for memory related settings. The XMP setting is an overclocking setting so it it not entirely ...

I realize that this response is a bit late but are you going to be doing this kind of thing often? I suggest investing in a Dediprog SF100 then. http://www.dediprog.com/pd/spi-flash-solution/sf100 You could also use a much cheaper device, Bus Pirate, to flash the BIOS as well. http://dangerousprototypes.com/docs/Bus_Pirate FlashROM can then be used to ...

Your computer is running into a Secure Boot violation. In all probability, this means that the computer's boot loader has been replaced with one that was not properly signed by Microsoft (or any other entity whose keys are part of the computer's firmware). In other words, you may well have accidentally installed malware on the computer, and the firmware has ...

Although this is for W7, any newly installed driver or software can cause this issue in W8 and that board, the instructions below should work to get it booting until you can figure out what triggered this issue on your PC Some users may encounter a "Secure Boot Violation" , which makes the system fail to boot into the operating system. To protect user's ...

Just writing an answer to summarize what helped the OP in the end (from the comments section). Though you should be able to get into bios from tapping the F2 key repeatedly, this did not work for OP. The solution therefore is to reset the bios to default settings so that you can access it again. To do this: 1) Unplug AC power and take out the battery. 2) ...

The correct key should be F2, try pressing it right from power on with your laptop or external keyboard. You may also get idea from this official source

Depending on where the ISO was obtained, it might not be properly created for UEFI booting. The file structure will be fine, including the \boot\efi directory, but the boot files will not properly load. In addition, according to Microsoft, Windows 7 cannot be used without CSM being enabled. Windows 7 does not support UEFI Class 3 (pure EFI) due to a ...

Your DVD will not work here !!! You have to create a bootable usb capable to booting into uefi. Make sure that you have win7 iso file. If not, you have create it from your dvd. Download and run Rufus. Make sure that partition scheme and target system type option is set to GPT partition scheme for UEFI. Then browse for win7 iso image and click start. ...

Are you sure you have setup the Bios to operate as UEFI only ? (Without legacy/CSM support.) I've seen a couple of Bios variants that wouldn't accept GPT disks for UEFI boot if the legacy support was also on. The logic seems to be based on the incorrect assumption that if you have legacy enabled your OS isn't UEFI capable and therefore also is MBR boot ...

Windows does not support boot from a USB disk. Instead of booting directly from the external disk, you could use VirtualBox to build a virtual machine that boots from the external USB disk. Here is one reference among the many that can be found : Using a Physical Hard Drive with a VirtualBox VM.

This motherboard uses a UEFI insecure boot (and the Asus CHF-V non Z version too). To bypass plug the Arch USB installer into your current Windows OS. Rename EFI-Bootx64.efi to Bootx64.bak Copy loader.efi to bootx64.efi

Ah, INACCESSIBLE BOOT DEVICE seems to be a windows 10 favourite... The first possible solution is outlined below, with an extra twist in case you need it. It seems to work for most people, but as your circumstances are slightly different we will have to see: At the blue screen where the error appears, click Advanced Options Click Troubleshoot Look for an ...
