Hello:
I followed the instructions here: http://www.centos.org/docs/5/html/5.2/Installation_Guide/ch02s04s01.html to put isolinux on a usb drive. When I boot from the usb drive, the installer comes up and I can do a network install. I have to say that is very impressive!
But, since I have a 4GB usb drive, I am thinking I can load the rest of the installation onto the usb drive so I do not have to use a network install.
I searched the Internet but could not find any instructions on doing that.
Can someone point me in the right direction?
Thanks, Neil

I currently use a different method.
1) make the first partition active fdisk /dev/sd[c]1 then a, 1 and w to write and quit 2) format the usb stick with fat or ext3 3) if you chose (a) fat : you will need to make syslinux work on the stick syslinux /dev/sd[c]1 (b) ext3 : you will need to use extlinux work on the stick extlinux /dev/sd[c]1 4) I extract the isolinux folder from the dvd iso 5) rename all isolinux to (a) syslinux - (b) extlinux 6) copy the dvd/cd iso(s) to your stick 7) normally you should get the same boot loader as when you would pop in the cd/dvd, centos install will start loading necessary drivers and then you will have to chose hard disk install and point to the drive where your dvd/cd iso(s) are 8) anaconda will start and well the rest you know
I have a 16gb stick with CentOS 4 32bit & 64bit and CentOS 5 32bit & 64bit to install my systems There is one problem, if you want to use kickstart, it will want the mounted iso files, have not yet figured a way to get around this or to get some command to mount the images somewhere
Regards, Tosh.
Tosh:
- make the first partition active fdisk /dev/sd[c]1 then a, 1 and w to write and quit
I did this.
- format the usb stick with fat or ext3
I formatted it using mkfs.ext3 /dev/sdc1
(b) ext3 : you will need to use extlinux work on the stick extlinux /dev/sd[c]1
I mounted the drive and did extlinux /media/disk
- I extract the isolinux folder from the dvd iso
I copied all the files from http://mirror.centos.org/centos/5/os/x86_64/isolinux/ to the root directory of the usb drive.
- rename all isolinux to (a) syslinux - (b) extlinux
I renamed the isolinux.bin to extlinux.bin and isolinux.cfg to extlinux.cfg
- copy the dvd/cd iso(s) to your stick
I copied the iso to the root directory of the usb drive.
- normally you should get the same boot loader as when you
would pop in the cd/dvd, centos install will start loading necessary drivers and then you will have to chose hard disk install and point to the drive where your dvd/cd iso(s) are
I tried to boot off the usb drive and I get a message that it could not boot the operating system.
Any ideas?
Thanks, Neil

Try using unetbootin.

Ok, I forgot to mention if you decide to use extlinux, you will need to rename to extlinux.conf also, execute the command on the drive /dev/sdc, not the mounted partition Maybe time to make a script to do this work?
Tosh:
execute the command on the drive /dev/sdc, not the mounted partition
When I do extlinux /dev/sdc, I get the Usage screen. The same thing happens if I do extlinux /dev/sdc1
The only way I could figure was to run extlinux on the mounted partition.
Any ideas?

ok, sorry, I seem to have forgotten again how I did it I had to make a new one today and indeed I had to use extlinux -i /mnt/disk/extlinux
Tosh:
Actually, I figured out how to do it:
1. Using fdisk, I created two partitions on the drive: /dev/sdc1 = 15 MB /dev/sdc2 = The rest I marked the first one bootable
2. I used dd to copy the diskboot.img to /dev/sdc1
3. Formatted /dev/sdc2 as ext3 and copied the iso images there
4. When I boot from the usb drive, I selected hard drive install and pointed the installer to /dev/scd2
It worked perfectly!
