Hello everyone.
I format my usb stick to be GRUB bootable.
I try to run some bootable ISO images.

some of the ISO's running good.
the other give me the "ERROR 60: File for drive emulation must be in one contiguous disk area"

someone can help me with that?

here is my MENU.LST:

splashimage (hd0,0)/BOOT/logo.xpm.gz
foreground 13c416
background f40404
timeout 80
default /default

title Start XP Pro
map (hd0,0)/XP-Pro.iso (hd32)
map --hook
root (hd32)
chainloader (hd32)
boot

title Start Paragon Partition Manager 2009
map (hd0,0)/paragon.iso (hd32)
map --hook
chainloader (hd32)

title Ubuntu8
map (hd0,0)/ubuntu8.iso (hd32)
map --hook
root (hd32)
chainloader (hd32)
boot

title UBCD
map (hd0,0)/ubcd.iso (hd32)
map --hook
root (hd32)
chainloader (hd32)
boot

The UBUNTU8 dont work but the UBCD work

1. that is NOT GRUB, it's grub4dos
2. not "any" iso works with mapping to (0xff) or (hd32)

See here for what is working:

Cannot say about Ubuntu "8", 9.04 has been reported to be working:

This WON'T work, unless it is a RAMDISK build:


You DO NOT need to add the command "boot" as last item in a menu.lst entry, it is implied (but needed when using command line).

Try to defrag the iso file that is returning 'Error 60' with 'WinContig' (http://wincontig.mdtzone.it/index_EN.htm) and report if this is working. It may help you partially atleast to resolve the error 60 issue.

...or use map --mem

i.e. Direct mapping:

vs. memory mapping or "indirect" mapping:

Jaclaz, thanks for the details on direct/ memory mapping.

little offtopic, sorry for intruding roeyhaim.

Jaclaz, not sure about others, but I was expecting that you would be able to help answering my query here <http://www.boot-land.net/forums/index.php?showtopic=8787> on 'Halt' command in Grub4DOS. Nobody replied hence thought it is very trivial or no-one else has experienced this problem.

Closed the topic however if you can help?

Thanks,

Replied there.
Doubtful whether it will actually "help".
My personal theory is that noone ever used that command in the last, say, 10 years, or the very few that actually did did not bother to post anything about their experience, exception made for this:
https://bugs.launchpad.net/ubuntu/+source/grub/+bug/220543

The point I try to raise is WHAT is a "real" situation where the command is useful/used?
