[Bug-xorriso] Error: output file must be given

[Edvard Hoegner]

Hello,

according to a german howto in order to access Win7 from ubuntu 12.04 
via virtualbox I have to generate a rescue disk. The following problem 
appears:

address@hidden:~$ sudo grub-mkrescue --modules=”linux ext2 fat fshelp 
ls boot pc ntfs” --output=/home/WindowsRAW_GRUB.iso 
~/WindowsRAWgrubiso.tempoutput file must be given
Usage: grub-mkrescue [OPTION] SOURCE...
Make GRUB rescue image.

  -h, --help              print this message and exit
  -v, --version           print the version information and exit
  -o, --output=FILE       save output in FILE [required]
  --modules=MODULES       pre-load specified modules MODULES
  --rom-directory=DIR     save rom images in DIR [optional]
  --xorriso=FILE          use FILE as xorriso [optional]
  --grub-mkimage=FILE     use FILE as grub-mkimage
  --diet                  apply size reducing measures [optional]

grub-mkrescue generates a bootable rescue image with specified source 
files, source
directories, or mkisofs options listed by: xorriso -as mkisofs -help

Option -- switches to native xorriso command mode.

What has to be changed in order to generate the iso?


Thanks a lot
