Making an USB storage device bootable:

****************************
a) running SPB-Linux 2rc5: *
****************************

First step: install bootloader syslinux

  if /dev/sda1 is your usb storage device, type

    makebootable /dev/sda1

  or if you want to use the  SPB-Linux mbr bootloader

    makebootable /dev/sda1 -mbr (see disclaimer on bottom)

Second step: boot the usb device with syslinux to install grub

  in the grub boot menu you can choose to install grub
  (the safe mode to install grub is when grub is running :-)

  After rebooting you get the grub boot menu

*************************************
b) running any linux distribution:  *
*************************************

First step: install syslinux

  copy this folder to your harddisk and
  if the device name of your usb storage device is /dev/sda1
  run

    dd if=/dev/sda1 of=bootorig.sec bs=512 count=1

  to save the old bootsector (and copy it to your harddisk(!) )

  then type

    syslinux /dev/sda1

  to install the bootloader syslinux

Second step: see second step with SPB-Linux (on top of this page)

*************************************************************************

If your usb storage device does not boot even if the syslinux bootloader
is installed you can try to use the spblinux mbr bootloader:
- usual mbr boot loaders use the CHS values in the partition table
- the bios might use other CHS values than linux/windows
- the spblinux mbr boot loader uses the LBA entry in the partition table:
  in some cases the bootsector of the active partition can now be loaded

Installation of mbr bootloader code spb2_mbr.sec
if(!) your usb storage device is /dev/sda

	dd if=spb2_mbr.sec of=/dev/sda

Disclaimer: spb2_mbr.sec is tested but the author cannot
give any warranty that spb2_mbr.sec works on your system.

this mbr bootloader gives some diagnostic output:
