Booting LFS from a USB flash drive

LinuxNewman · 08-04-2009, 03:20 AM

Hi All !
I was wondering about carrying my LFS version 6.4 in my pockets and using it on different computers. For this, the most fascinating idea is to carry it in a pen drive and whenever I want to use it, I should be able to insert it in any computer and boot from it.
I searched the intrenet about this. But all the websites were telling me to download specific distros like UNetBootin,Knoppix etc and use them for booting from pen drive. The methods mentioned were as simple as installing them on the pen drive and to do modifications in BIOS.
But I want my Linux system to use on pen drive. Suppose I copy my whole LFS partition in my pendrive, but how will I make any computer boot from it? Where will be my boot loader who will tell that LFS has to be booted from a pen drive which is inserted? Can you please tell me what steps should be taken? I am confused

One fairly popular USB bootable Linux which I have used is Pendrive Linux, found here; http://www.pendrivelinux.com/ , also several other's do have a version to install onto a USB flash drive such as Ubuntu, Slax, but for your LFS Linux system you need to check their web site for that. You first format it as FAT or FAT32, then extract the files to that USB device root drive, (not into a folder), then run either a script file or a batch file to make it fully bootable, and then set your BIOS correct for boot to USB, or use your F10 or F12 boot order menu key to select the boot first device.

Forgive me, I am new. I did not understand the following things:

1."then extract the files to that USB device root drive" - What is meant by USB device "root drive"?

2. "then run either a script file or a batch file to make it fully bootable" - Believe me, I have never heard of any such kind of script file or batch file which can make the device fully bootable. Can you please tell me what is that and how is it done?

Thanks

you have Built LFS?

If so, I would think you know what root of usb drive is?

top level of usb drive,

and, yes, scripts exist that will make usb bootable
or do it yourself thru terminal

I have never heard of LFS on a stick?

Does LFS have usb drivers?

you will find the scripts in Linux Live scripts
