I've got UBCD on my USB stick, and have added several images to the \custom dir that work well. I have been trying to add Fedora 10, but it doesn't appear to have a .img for this. Each one I use from the \images folder gets to "booting kernel", then just sits.

This is to allow running a network install from the USB stick.

I've spent a couple of hours on google, and have found nothing relevant for Fedora10.

Any suggestions?

you can't add fedora as a image file , what you can do is extract its content on ubcd and add the entry in ubcd menu for fedora.

If you want to know in detail , then ask by mentioning what you have tried till now.

I don't want the whole OS, just enough to boot to the network install.

For example, I have various RedHat installs, and for each of these, I have a diskboot.img file, and a pointer in Custom.cfg. These are available to me in the User-defined Tools section, and I boot to the image I want to install, then select FTP as the install method.

I want to do this for Fedora, but if I have to have the whole OS, I'll look for another distro that does have a diskboot image I can use.

There is a file "boot.iso" of about 127MB for fedora 10.
you can use that to boot.
extract its content in root directory of ubcd and add a entry for it in ubcd.
you can not add it as image cause it is too long for isolinux to boot.....you have to extract its contents.

Thanks for the pointer to the boot.iso. I got Fedora 10 to boot to a network install, and only added 20MB to my usbstick.

Here's what I did -

Download and extract Fedora-10-i386-DVD.iso to your website (there wasn't an option in the boot to use FTP, only CD/DVD, NFS, and URL). I created a fedora10 directory in the root of the site.

Browse to images\pxeboot

Copy initrd.img and vmlinuz to UBCDROOT\fedora (create directory)

Add to menus\bootdsk2.cfg
LABEL fedora
MENU LABEL Fedora 10
KERNEL /fedora/vmlinuz
APPEND initrd=/fedora/initrd.img

I had to add the changes to my ubcd image, then "burn" it back to my usb stick.

Boot to UBCD, select DOS/Linux Boot Disks, then Linux Boot Disks, then Fedora 10. When prompted for the URL, enter http://sitename/fedora10 (or whatever dir you put your extracted files into).

I did have an issue with the video (USB LCD got scrambled) when it first tried to load the GUI part of the install, but when I tried again, it worked.

I ran this twice, with success both times, but if someone else wants to follow these steps and confirm the results, I would greatly appreciate it.
