hello all

im trying to install my rhel 5.1 from nfs, this is ok, but u want to \create a disk on key with the boot iso to boot it up to nfs
what is the process to create usb disk on key boot one?

thanks

Your first step should be downloading the latest version of syslinux rpm and installing it on you linux machine.

After downloading it you should

Configuring the USB Flash
Partitioning the USB
First of all you need to erase all existing partitions on the USB by using FDISK command.
For example :
#fdisk /dev/sdb

sdb is you USB device for each device its different.

Get into fdisk and erase the partition table, then write the changes

Example:
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.

Now the flash is clean and ready.



Making the USB Bootable
In order to allow the USB to be bootable we and for the boot image to work with partition we will use syslinux command.
# /usr/lib/syslinux/mkdiskimage -4 /dev/sdb 13 64 32
This command tells the USB to act as standard zip disk, 13 tells the image at which cylinder to stop (basically you decide here you boot partition size).
Now it’s to DD the boot image from Red Hat installation CD 1 to USB.
#dd if=”path to mounted CD”/images/diskboot.img of=/dev/sdb4
Now the USB is bootable and ready for installation

now you'll see a small partition on you flash disk which holds the boot abilitys.

All left to do is create another partition and plant on it kickstart file
pointing to your nfs location or just putting ISO files of your OS and using them (much faster option).

thank u for the answer
