Yes, my memory isn't that great, but it is in the install guide: http://www.centos.org/docs/5/html/Installation_Guide-en-US/ch02s04.html#id3098219 > In any case, I tried dd-ing this to /dev/sdb (the USB stick). > > [tim at helen dvd]$ sudo cp images/diskboot.img /tmp > [tim at helen dvd]$ cd /tmp > [tim at helen tmp]$ sudo dd if=diskboot.img of=/dev/sdb > 24576+0 records in > 24576+0 records out > 12582912 bytes (13 MB) copied, 0.766341 seconds, 16.4 MB/s > > But when I re-booted my laptop with the USB stick in > (having made sure it was top of the boot order in the Bios) > it failed to start. > > I re-formatted the USB stick under Windows, > and tried dd-ing diskboot.img to /dev/sdb1 > but the outcome was the same. It should go to the raw disk device, not a partition and you shouldn't need to format first. I can't help much with this part since I normally boot a CD with 'linux askmethod' at the prompt to get to that point. I guess you could try grabbing a different copy from a mirror site like: http://centos.cs.wisc.edu/pub/mirrors/linux/centos/5.5/os/i386/images/ -- Les Mikesell lesmikesell at gmail.com
