Heya folks,

I keep seeing posts that claim UBCD supports the grub2 loopback iso feature, i.e. the iso is simply on the hard disk's file system, and it boots out of the iso directly. I am having a heck of a time figuring out how to do this. Is it actually true that UBCD supports this feature?

I have a pile of live cd iso images that I am booting, and would like to throw UBCD into the list.

thanks!

It is never stated that UBCD supports the grub2 loopback iso feature.
UBCD supports grub4dos and MEMDISK iso booting (uses INT13h for accessing the iso). The grub2 loopback device works different. It can only read some files inside the iso and boot them. This is only useful for linux ISO's, where you can read the kernel and initrd from the iso image and boot it.

MEMDISK and grub4dos can be booted from grub2
Code:
menuentry "UBCD with MEMDISK" {
   linux16 /memdisk iso raw
   initrd /ubcd502.iso
}
menuentry "UBCD with grub4dos" {
   linux16 /grub.exe --config-file="map (rd) (hd32); map --hook; root (hd32); chainloader (hd32);"
   initrd /ubcd502.iso
}
