Where is syslinux.cfg

CFG error. CFG failed to load. CFG is missing or corrupt. Runtime Error! CFG This application has requested the Runtime to terminate it in an unusual way.

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred. In the search results, find and click System Restore. Follow the steps in the System Restore Wizard to choose a relevant restore point. Restore your computer to that backup image. CFG error, please proceed to the Step 2 below.

If this Step 2 fails as well, please proceed to the Step 3 below. In the Windows Update dialog box, click " Check for Updates " or similar button depending on your Windows version If updates are available for download, click " Install Updates ". After the update is completed, restart your PC. CFG Files". Click the appropriate "Download Now" button and download your Windows file version. All options here apply to all the bootloaders of the Syslinux family, unless otherwise noted.

Since version 4. If no configuration file is found, then PXELINUX will start a timer to reboot the system in an attempt to restart the boot process and resolve a possible transient issue. All paths to file names inside the configuration file are relative to the Working Directory, unless preceded with a slash.

This is also valid for the command line interface. A line comment. Insert the contents of another file, at this point in the configuration file. Files can currently be nested up to 16 levels deep, but it is not guaranteed that more than 8 levels will be supported in the future.

Multiple uses will result in an override. As of version 1. You might want to include this option manually. Select a specific user interface module typically menu. If not, the first instance is used, but might result in an error or undesired behavior.

Prior to version 3. In other words, multiple instances of the same directive will result in only the last one being effective. Add one or more options to the kernel command line. These are added to both, automatic and manual boots.

The options are added at the very beginning of the kernel command line, usually permitting explicitly-entered kernel options to override them. This is the equivalent of the LILO "append" option. Append nothing. The bitmask is an OR sum of the following integer options:.

Note : The use of option 1 is no substitute for running a DHCP client in the booted system and should instead only be used to seed the client for a request. Note : The use of this option is not recommended.

If you have to use it, it is probably an indication that your network configuration is broken. The following CPU features are currently reported; additional flags may be added in the future:. DMI : [5. As of version 3. DA1A-0B2E :. Load a kernel-like file image with automatic filetype detection based on file extension case insensitive , listed under the non-auto-detecting directives, defaulting to LINUX.

Do not symlink them. Now install the bootloader. Alternatively, for a FAT boot partition use syslinux , where the device is unmounted :. See Master Boot Record for further general information. For an MBR partition table , ensure your boot partition is marked as "active" in your partition table the "boot" flag is set.

Applications capable of doing this include fdisk and parted. It should look like this:. An alternative MBR which Syslinux provides is: altmbr. This MBR does not scan for bootable partitions; instead, the last byte of the MBR is set to a value indicating which partition to boot from.

Here is an example of how altmbr. In this case, a single byte of value 5 hexadecimal is appended to the contents of altmbr. Using sgdisk the command to set the attribute is:. To check:. The Syslinux configuration file, syslinux.

The bootloader will look for either syslinux. This is a simple configuration file that will show a boot: prompt and will automatically boot after 5 seconds. Syslinux also allows you to use a boot menu. To use it, copy the menu and libutil modules to your Syslinux directory:. Since version 5. See the Syslinux wiki for the module dependency tree. For more details about the menu system, see the Syslinux wiki. Syslinux also allows you to use a graphical boot menu. To use it, copy the vesamenu COM32 module to your Syslinux folder:.

This configuration uses the same menu design as the Arch Install CD, its config can be found at gitlab. The Arch Linux background image can be downloaded from there, too.

Since Syslinux 3. However, the background picture has to have exactly the right resolution, as Syslinux will otherwise refuse to load the menu. The default values are both 0 which is the upper-left hand corner of your monitor. Conversely, a negative number starts from the opposite end of the screen e. VESA standards are commonly a maximum of 25 rows and 80 columns, so going higher than those values might move the menu off the screen, potentially requiring editing from a rescue CD.

In the simplest case , the value of the root parameter needs to be replaced; see Persistent block device naming for supported methods.

Holding either Shift or Alt , or setting either Caps Lock or Scroll Lock , during boot will allow for options other than default to be used. See the upstream wiki for additional alternatives. Syslinux has two levels of bootloader security: a menu master password, and a per-menu-item password. In syslinux. The passwd can be either a cleartext password or hashed: see official documentation.

Syslinux BIOS cannot directly chainload files located on other partitions; however, chain. If you want to chainload other operating systems such as Windows or boot loaders, copy the chain. Then create a section in the configuration file:. To use the MBR identifier, run the command. Using the hexadecimal number under Disk identifier: 0xf00f1fd3 in this case, the syntax in syslinux.

For more details about chainloading, see the Syslinux wiki. If you have GRUB installed on the same partition, you can chainload it by using:. Alternatively, it is also possible to load GRUB as a linux kernel by prepending lnxboot. The file lnxboot.

The factual accuracy of this article or section is disputed. Chainloading another bootloader such as Windows' is pretty obvious, as there is a definite bootloader to chain to. But with Syslinux, it is only able to load files residing on the same partition as the configuration file.

The following instructions assume you have Syslinux installed already. From a booted Linux likely the partition that Syslinux is set up to boot , mount the other system's root partition to your desired mount point.
