I have a USB drive of 4 GB and I want to make the drive as bootable. I used the command /sbin/mkbootdisk --device /dev/sdb1 "kernal version" ( sdb1 is my pen drive).When i ran this cmd,it gave me an error saying not enough space to write. Could somebody help me out??

You could also simply install a system as normal (such as from a cd install disk) installing the system (including grub) to the pendrive. You wouldn't need to use fat32. Ext2 may be best for a pendrive. Adjust your /etc/fstab on the pendrive so that the noatime option is used.

Also, I was a Dell CSE and if other hardware is like Dell there is a setting in the BIOS that you have to change to make the USB available as a boot device...
