similar to: Using syslinux on the PMBR of a GPT partition table

Hi all, I was using grub2 for booting Archlinux x86_64 in my GPT Internal HDD (/dev/sda) then I switched to syslinux/extlinux. It was working fine but suddenly it staring showing "Boot Error" message on screen. I googled for a solution and tried all syslinux versions from 4.04-pre4 down to 4.03-stable but non of them worked. I don't know what suddenly changed caused this

I'm not saying for certain these are the reasons for such dependencies, but they might (and perhaps

As I understand that, so in _my words_:

hello every body, I'm trying to build an isohybrid image based on syslinux able to boot on bios and uefi with optical disk or usb key. I've build a 16Mb hard disk image (core.img) with necessary parts for bios (legacy bootable partition, protective mbr, gptmbr.bin & syslinux installation) and for uefi (gpt, esp, /efi/boot/bootx64.efi & syslinux files). my hard disk image is ok -

This patches add support for dynamic sectors to GPT MBR code. First 3 patches are trick and optimizations to gain some space for the forth patch. I have a modified version of SeaBIOS, some code and some script o test it I'll send on a different mail.

Does anyone know how to install the gptmbr.bin onto a USB drive with Windows? I noticed that it would be really easy to modify the source of the installer to install gptmbr.bin instead of mbr.bin with the -m flag, but I'd like a solution that doesn't require me to maintain my own custom syslinux. I'm open to writing and submitting a patch to add a new flag (say -g) to install

when you say """ Unfortunately, syslinux.efi v.6.03 is not capable of booting optical """, you talk about isolinux.bin ? because my iso image with a "good" alternate eltorito boot image (eg. "uefi ready") is booting with qemu (qemu -cdrom core.iso -bios uefi.fd) and is also booting in hard disk mode (qemu -hda core.iso -bios uefi.fd). Le mercredi

(Do i get the language wrong ?) Well I've been looking at this. It seems gptmbr.S

Oh somehow I never noticed that "bootsecfile" option. That's probably what I need to use. I was looking at the source to see how the --mbr flag works and thought that there should be a way to do the same thing with the other mbr files.

Version 2 of these patches includes optimisations suggested by H Peter Alvin to save bytes: * Use memory-mapped I/O register to read keyboard shift flags * Don't reload DX from memory; move immediate byte to register Tested using mbr.bin.

I need to create one bootable UEFI disk partition that contains all the space on the disk. The steps must work in a shell script. Ideally with syslinux/extlinux but if not possible then grub. How to do this? Surely it should be dead easy, a handful of lines? Nothing I do works. This is what I have so far: DISK_DEVICE_NAME_CURRENT_OS=hda echo remove all partitions sudo /usr/local/sbin/sgdisk -Z

I'm trying to make a drive that can boot with both UEFI and BIOS. I've built the drive successfully on my Linux machine, but can't get the drive to build with my Windows machine. The only step that's different right now, is that I use `extlinux --install /media/drive` to install with Linux, and `syslinux.exe --install d:` to install with Windows. In fact, I can prepare a drive with

Hi, I just installed FreeBSD 9.0-release / amd64 on a new machine (Acer Aspire X1470). I installed from a usb memory stick (the default amd64 image), which I booted by pressing "F12" and selecting it from the boot menu on the machine. I installed on a SSD (which replaced the hard drive originally in the machine), using the default scheme for 9.0 (GPT). The installation was painless (many

If there is a GPT partition layout, then what should be read and restored for each partition is the GPT type and not the MBR ID.
