Hello,
I am building a recovery usb key. I wish to have a menu to select any of a number of isoimages to boot and install. iso images include ubuntu server and desktop, knoppix, gparted, nst, redhat* and even microsoft*. I have begun with ubuntu 12.04 lts server as a starting point.
I have had limited success with grub (https://help.ubuntu.com/community/Grub2/ISOBoot) and syslinux (http://www.syslinux.org/wiki/index.php/The_Syslinux_Project), but those aren't really my problem. it's relatively easy to boot the proper kernel and initird.
The problem is telling the ubuntu installer where to find the iso image.
The ubuntu 12.04-desktop-amd64 installer looks for the iso images on pre-mounted hard drives, which means it won't find it on usb keys, even with the iso-file/filename option.
My next step is to modify the initrd. If I insert a command to mount the usbkey and then loopback mount the iso, I think it will work.
Does anyone have another suggestion?
Thank you for your time...
