Question Help me make a Live USB drive with a particular ISO? (Details inside)

Hi guys. I posted this question in LFS, but no one really seemed to have done this, so I decided to move my question.
Could someone organize this into a step-by-step list, and give me a brief explanation on how to install GRUB on a flash drive?
And here's a link to the ISO I downloaded, *WARNING* It's 633 MB.


If you want to boot this CD on a computer without a CD-ROM drive, follow the steps below.

Store the ISO image of this CD as a file on a partition formatted with one of the following filesystems: vfat, ntfs, ext2, ext3, ext4, jfs, reiserfs, reiser4, xfs

Copy the boot/isolinux/{linux,initramfs_data.cpio.gz} files from the CD to your hard disk

Configure the boot loader to load “linux” as a kernel image and “initramfs_data.cpio.gz” as an initrd. The following parameters have to be passed to the kernel:

rw root=iso:/dev/XXX:/path/to/lfslivecd.iso rootfstype=fs_type

where /dev/XXX is a partition where you stored the LiveCD image, and fs_type is the type of the filesystem on that partition. You may also want to add “rootflags=…” option if mounting this partition requires special flags.

If there is only Windows on the target computer, please use grub4dos as a boot loader. It is available from

Install GRUB on a flash drive, then follow instructions in the “BOOTING FROM ISO IMAGE” above, using a partition on your flash drive. The following tips will ensure that the flash drive is bootable in any computer:

Use the persistent symlink such as “/dev/disk/by-uuid/890C-F46A” to identify the target partition.

Add “rootdelay=20” to the kernel arguments.

I found the step by step instructions on how to Install Grub On A Flash Drive:

I looked at the lfslivecd-x86-6.3r2145.iso that you linked to.

I'm not sure how to re-write these instructions to make them any easier but if it were me I would do a little more research so you make the partition (ext3 or ext4)correctly.
Also configuring the boot loader may not be a simple task. I strongly suggest you read this documentation on it go slow and take your time.

Good luck

Odd, grub4dos might have been able to boot directly to the ISO image. Since this is to be used in place of a real cd/dvd, why not use grub4dos.

Kind of a trick question also. Grub is not a standard sort of tool exactly. Depending on how you got it, may affect how it is used or works. Some may not boot a usb.

I'd also even wonder if the iso is a hybrid iso image.

Just for some more info, has many how to's for this sort of issue. Each distro is different too and may fail on some solutions.

To test the Fedora 18 Beta Test Candidates and copy various ISO images to a USB drive, I have used LiLi USB Creator for Windows. It is at For Fedora, I use LiveUSB Creator, which has a Windows version and a Fedora version. Check out You can use LiLi to make a Live Fedora USB drive as well.

If your particular ISO is not supported in LiLi USB, you can communicate to the people who support the product to get it added.
