[CentOS] Install CentOS directly from usb drive?
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?

Re: [CentOS] Install CentOS directly from usb drive?
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!
