UBCD50RC1 works fine. It is the UBCD4Win UBCD plugin that sucks.
It just assumes that you can rename the ubcd50RC1.iso file to ubcd5.iso.
This is not the case. Parted Magic needs to find the ubcd iso, to find the rest of its files.
In the Syslinux config file for Parted Magic, you can find:
APPEND iso_filename=ubcd50RC1.iso acpi=off edd=off noapic load_ramdisk=1 prompt_ramdisk=0 rw vga=791 sleep=10 loglevel=0 keymap=us
' parameter specifies the iso name Parted Magic will look for. If you edit this parameter on the fly with the 'e' command of grub4dos to 'iso_filename=ubcd5.iso
', Parted Magic will boot (Parted Magic will look in /, /images and /pmagic for the iso file).
Renaming and mapping the iso will work for all dos based tools, but not for all linux tools (except if they need only a kernel and initrd, which is the case for almost all tools included in UBCD, except Parted Magic and Avira Rescue CD).
Avira Rescue CD won't work with iso mapping (without patching).
You can extract the /antivir dir of the UBCD50RC1 iso and place it in the root of your CD or USB partition.
Someone made a patch to Avira Rescue CD a while ago, to support iso mapping:http://forum.avira.com/wbb/index.php?pa ... adID=88261
Complain to Avira, but don't expect that they will include it.
could be made a bit better (boot the isolinux menu instead of the grub4dos one):
LABEL UltimateBootCD for DOS 5.0
APPEND --config-file="timeout 0;default 0;title UltimateBootCD for DOS 5.0;ls /images/ubcd5.iso || find --set-root /images/ubcd5.iso;map /images/ubcd5.iso (0xff);map --hook;root (0xff);chainloader(0xff)"
Runs UltimateBootCD for DOS 5.0
BCDW is a very old boot loader (and isn't updated anymore). I don't recommend it.
Which version of ISOLINUX does UBCD4Win use?
Download Ultimate Boot CD v5.0
