I got unetbootin and I made a bootable disk
But now When I select the OS from usb, it does nothing.
The selection menu doesn't go away. I can select it again and again, nothing happens.

Hi, I created the small OS mentioned in http://wiki.osdev.org/Bare_Bones. It is working fine in QEMU. But when I create its bootable usb using Code: sudo dd if=myos.iso of=/dev/sdb && sync it doesn't load correctly during booting. Though it is able to detect the flash drive, It throws error disk is not loaded ,going to grub rescue mode. What to do next? |

Google "Create bootable USB from ISO". And can I respectfully suggest that Google is a good starting point for relatively trivial queries. |

When I burn my iso to usb, I usually run with -bs specified. Specifically I run Code: dd if=myos.iso of=/dev/sdx bs=4M Of course /dev/sdx is the device to write the image to. I usually insert this a script after I wrote to /dev/sda several times late at night. |

This is pretty easy. 1. Make a partition table and a partition on the USB pen drive. 2. Create a file system on the partition. 3. Mount the created partition. 4. Copy your files (kernel, etc.) there. 5. Unmount. 6. Install GRUB on the USB pen drive (not partition) using grub2-install (or maybe grub-install, as in Ubuntu). 7. Reboot and boot from the USB pen drive. |
