I can mount without problems all kind of ISOS with the mount command, to a /tmp directory:

sudo mount -o loop my.iso /tmp/my_dir

If I run ls -l command I get

dr-xr-xr-x 1 root root 2048 abr 19 23:16 my_dyr


But I have come to an issue with the Hiren's Boot ISO. I can mount it using the above command, but then the /tmp/my_dir is unaccesible! Running ls -l again i get

drwx------ 3 nobody  401 2048 nov  7  2012 my_dir

I can't chmod or chown either.

I really don't know what is special about this particular ISO, or if is a feature of some ISOS I don't know about. Maybe somebody can enlighten me.


  • chamoro Please type mount command after you've mounted Hiren's Boot ISO to check what the filesystem is set for mounted iso. I assume that this iso is mounted as iso9660 but you should force to mount this iso as UDF. – Yurij Goncharuk May 29 at 20:02
  • @YurijGoncharuk issuing the command sudo mount -t udf -o loop Hirens.BootCD.15.2.iso /tmp/isos_mount_dir/ I get wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error – guillermo chamorro May 29 at 20:19
  • What is the output of file Hirens.BootCD.15.2.iso – Mark Plotnick May 29 at 20:59
  • @MarkPlotnick Hirens.BootCD.15.2.iso: ISO 9660 CD-ROM filesystem data 'HBCD 15.2' (bootable) – guillermo chamorro May 29 at 21:04
  • @guillermochamorro try to add nojoliet,unhide options when you will mount. – Yurij Goncharuk May 29 at 21:21

Finally I got it, adding the user id and group id:

sudo mount -ro uid=1000,gid=1000 Hirens.BootCD.15.2.iso ~/Tmp/foo/
