If you did all of that correctly, then it should now be booting your USB drive in the way that you specified. Of course, this will vary from distro to distro. Check the output of the ls command (in GRUB), to see a list of USB devices/partitions. Linux /path/to/kernel PARAMETERS MAYBE_MORE_PARAMETERS GRUB works similarly here are some example GRUB commands: set root='usb0' Now, look at the ISOLINUX menuentry it’ll look like this: kernel /path/to/kernel append PARAMETERS initrd=/path/to/initrd. Now, find the device file for your usb drive.
#INSTALL GRUB ON USB TO BOOT ISO INSTALL#
Install them using the package manager, for instance on Ubuntu : sudo apt install grub-pc-bin grub-efi-ia32-bin grub-efi-amd64-bin. Devuan versions based on Debian 8.x may also have the same issue. The x8664-efi, i386-pc and i386-efi folders need to be present in order to install the corresponding bootloader on the usb drive. If it is a live USB, the /boot/grub folder includes a. However, since GRUB puts its config files in /boot/grub, where those will go depends on what kind of installation you have in the USB drive. This is important, if you want 64-bit booting on your system. (where sdb is your USB drive) should work when booted from the hard drive with USB drive connected. NOTE: Debian 8.6 ISO only lists 32-bit boot options in txt.cfg. Just keep searching through the image, until you find the correct ISOLINUX configuration file. For dual-architecture ISO images (i686 and x86_64), there may be separate files directories for each architecture.
For example, if the file found were foo.cfg, you would use this command: cat (usb0)/isolinux/foo.cg`Īnd so on, until you find the correct menuentries for ISOLINUX.įor Debian-based distros (e.g., Ubuntu, Devuan), there are typically menuentries listed in /isolinux/txt.cfg or /isolinux/gtk.cfg. I would suggest to download the G.04.0 Image once again >Extract the SPP ISO Image to the folder >Open the extracted folder and then open the 'usb' folder and run the usbkey.exe >Follow the onscreen instructions to create usb bootable with SPP. Here’s an example: cat (usb0)/isolinux/isolinux.cfgĮither the output of this command will be the ISOLINUX menuentries for that ISO, or link to other.
Get the device name from the above output (e.g., usb0).
If the ISOLINUX parser or Search for GRUB configuration options won’t work, then press C in GRUB to access the command line, then run the ls command: ls You must adapt them appropriately, for whatever GNU+Linux distribution it is that you are trying to install. They may or may not be correct for your distribution. Last edited by sysmatck June 10th, 2015 at 11:38 PM.Booting ISOLINUX Images (Manual Method)
#INSTALL GRUB ON USB TO BOOT ISO MANUAL#
Search for your machine’s manual if needed. Each manufacturer has its own keys to do it. In order to install GRUB under a UNIX-like OS (such as GNU), invoke the program grub-install (see Invoking grub-install) as the superuser (root).
#INSTALL GRUB ON USB TO BOOT ISO PC#
Or you can choose what drive to boot as soon as you turn on your computer. For information on where GRUB should be installed on PC BIOS platforms, see BIOS installation. To boot the USB drive you can set your machine firmware to search first for the USB device (boot order). iso at /iso.įirst and most important, deactivate secure boot on your computer’s firmware. Use # to comment those lines you don’t want to use, e.g.
#INSTALL GRUB ON USB TO BOOT ISO HOW TO#
There is lots of examples on the web about how to configure grub2 menu. Note that the most important variable to set is isofile. iso files you want to load in /mnt/iso/ and setup grub.cfg like the existing examples… PS: If you have problems to copy and paste content on /mnt, you can use sudo to do it PS: Grub2 installation might throw some error messages, just ignore it.
Sudo grub-install -removable -boot-directory=/mnt/boot -efi-directory=/mnt/EFI/BOOT /dev/sdb
