similar to: Chainloading from Vista x64 bootloader to Extlinux?

Hey guys, what I am trying to do is a chainload into grub2 installation in a DomU. So far I determined, PV-GRUB does not understand grub2''s grub.cfg notation. So I created a dummy menu.lst which has the needed root kernel and initrd rows and then referenced this to the DomUs config. The main intention to do this, is to be able to use kernel upgrades without touching the menu.lst for

Chainloading a Linux system with syslinux fails unexpectedly with the lines: WARN: No MBR magic, treating disk as raw. ERR: Unable to find requested disk / partition combination. boot: coming after the usual lines SyslinuxBOOT .... (in UEFI menu) linuxBLFS (in syslinux menu) SUMMARY (additional gory details available upon request) ~~~~~~~~~

I will not push half-finished features into production. I will not push half-finished features into production. I will not push half-finished features into production. I have pushed out syslinux-3.07-pre1; this should have a fix for the chainloading problem. It actually turned out to be multiple problems, some of which makes me believe chain.c32 probably hasn't worked since 2.12 or so.

Hi, we use PXELINUX in our product to show a boot menu on client computers, with options like "Boot from local hard disk", "Install Windows", etc. Unfortunately, a lot of computers seem to have broken BIOSes and won't boot with the LOCALBOOT command, and need to be booted with chain.c32 instead. We also have encountered some computers where it works only the other way -

Hi, I am having troubles with chainloading and hopefully someone can provide me with some guidance. Here's what I am trying to do: * the media is a USB key * I have created a GPT on it * I have created an EFI partition, where I have installed the EFI flavor of syslinux, the various .c32 files required for chainloading and the configuration file which tells syslinux what to chainload

Hi, I have two disks in my computer with each one, a bootloader. The first disk (a usb key) boot with syslinux bootloader that launches a tiny kernel. The second disk has grub 2. I need to boot the disk 2 with grub, from the tiny kernel of the disk 1. So i use the bios interruption 0x19 to load the second bootloader, but this solution doesn't works. If i use a my own bootloader, the

DRMK (Dell Real Mode Kernel), now used in their DOS-based diagnostic images (probably about 2-4 years), has a rather unusual entry into the IO file (DELLBIO.BIN; similar to IO.SYS and IBMBIO.COM). After fumbling around with it over the last few days, I _think_ I've figured out the quirks of this entry point (and successfully tweaked chain.c32 to do such). dl Usual; drive number bp 0 cs

Hi, This is off topic for this list, but someone on this list may be able to point me in the right direction. For a couple of years I have been using ISOLINUX + MEMDISK and Smart Boot Manager to chainload a CD-ROM boot after loading a floppy image into RAM with MEMDISK. My problem now is that Smart Boot Manager does not support/detect SATA optical drives used in new hardware. Does anyonw

Hi, could one give me a _working_ example of a configuration that uses chain.c32? I would like to test chainloading and it doesn't seem to work :( But there is still a chance that there is my fault. best regards p.o.

I have an interest in booting Windows PE from PXELinux, and it seems that wimboot from ipxe project is the solution. http://ipxe.org/wimboot MENU LABEL Windows 8.1 Enterprise PE Rescue (wimboot) com32 linux.c32 /wimboot APPEND initrdfile=/windows/win81/bootmgr,/windows/win81/boot/bcd,/windows/win81/boot/boot.sdi,/windows/win81/sources/boot.wim The initrdfile= is supported in Syslinux from

Hi! I have bootable (USB flash) disk, that _appears_ to be using syslinux. (the word syslinux is in the PBR, in the hexdump). How can I chainload it? The payload seems to be a file that I tried load with COMBOOT, COM32 etc, but nothing works (they report that the file is not in proper format, wrong magic number or simply crash). How to proceed? is there a 100% way to confirm that it is really

I have a number of syslinux based USB sticks which can be booted from PCs that support USB boot. I also have a number of PCs that do not support USB Boot. They are running Windows 2000 and Windows XP typically from ntfs formatted single partition drives. Is there a way to chainload syslinux residing on a plugged in usb stick from boot.ini? I've seen instructions for how to do this for OSs on

Hello, I have found what seems to be a wee bit of a bug in the ISOLINUX menu. :) I have chainloaded a second menu as per the example at the very bottom of README.menu. When a menu item is selected in the second menu, <Enter> is pressed, the menu complains that it cannot find an image with the name of the label. So if the label is Image_1, it says it cannot find that. However, if

Lu Wei, For the DOS portion make sure you have a working FAT-32 DOS Bootable Drive first. Back up it's boot sector into a file. This file will probably be 512 Bytes and if you were to open it with a Hex editor it would start with ".X.MSWIN4.1" and end with "SYS~..WINBOOT SYS..U" This would of course be looking at the ASCII view. Assuming you put the file in the DOS
