6 grml2usb - install grml ISO(s) on usb device for booting
10 grml2usb [ options ] <ISO[s]> <device>
12 *******************************************************************************
13 Important! The grml team does not take responsibility for loss of any data!
14 *******************************************************************************
20 grml2usb installs grml on a given partition of your usb device and makes it
21 bootable. It provides multi-iso support, meaning you can specify several grml
22 ISOs on the command line at once and select the grml flavour you would like to
23 boot on the bootprompt then. Note that the *first* ISO specified on the grml2usb
24 command line will become the default one (that's the one that will boot when
25 just pressing enter on the bootprompt or wait until the boot timeout matches).
28 By default a compatible master boot record (MBR) is installed on the device
29 (being for example /dev/sdX when executing 'grml2usb grml.iso /dev/sdX1') and
30 syslinux is being used as default bootloader. Avoid installation of the default
31 MBR using the '--skip-mbr' option or if you encounter any problems with the
32 default MBR consider using '--syslinux-mbr' instead.
35 Whereas grml2usb is the script to install recent grml ISOs (>=2009.10) the
36 script grml2usb-compat supports older grml releases (<2009.10) as well.
42 The ISO[s] should be the path to one or multiple grml-ISOs and/or the path to
43 the currently running live-system (being /live/image).
45 The device either might be a device name like /dev/sdX1 or a directory. When
46 specifying a device name the device is mounted automatically. When specifying a
47 directory grml2usb is assuming that you did set up a bootloader on your own (or
48 don't need one) and a bootloader won't be installed automatically.
50 The following options are supported:
52 *\--bootoptions=...*::
54 Use specified bootoptions as default. To use flavour name as a argument for a
55 boot parameter use %flavour which will be expanded to the flavour name. To add
56 multiple bootoptions you can specify the option multiple time.
58 *\--bootloader-only*::
60 Do *not* copy files but instead just install a bootloader. Note that the boot
61 addons are copied to /boot/addons at this stage as well. If you want to skip
62 copying the boot addons consider using the --skip-addons option.
66 Copy files only but do *not* install a bootloader.
70 Avoid executing commands, instead show what would be executed.
71 Warning: please notice that the ISO has to be mounted anyway, otherwise
72 identifying the grml flavour would not be possible.
76 Format specified partition with FAT16.
77 **Important:** this will destroy any existing data on the specified partition!
81 Force any (possible dangerous) actions requiring manual interaction (like --fat16).
85 Install grub bootloader instead of (default) syslinux.
89 Install grub into MBR (Master Boot Record) instead of PBR (Partition Boot
90 Record). Check out <<mbr-vs-pbr,the 'mbr-vs-pbr' section in the FAQ of this
91 document>> for further details.
95 Display usage information and exit.
97 //////////////////////////////////////////////////////////////////////////
100 Install specified initrd instead of the default. You might want to specify
101 option *--kernel* as well. (Be aware when using multiboot setup.)
102 [Notice: not implemented yet.]
103 //////////////////////////////////////////////////////////////////////////
105 //////////////////////////////////////////////////////////////////////////
108 Install specified kernel instead of the default. You might want to specify
109 option *--initrd* as well. (Be aware when using multiboot setup.)
110 [Notice: not implemented yet.]
111 //////////////////////////////////////////////////////////////////////////
115 Install master boot record (MBR) with integrated boot menu: interactively choose
116 the partition to boot from, with a timeout to load the default partition, or
117 boot from floppy. When NOT using the --mbr-menu option a MBR with LBA and large
118 disc support but without an integrated boot menu is installed (so it's not
119 visible at all but instead directly jumps to the bootloader - being grub or
120 syslinux). Note: This options is available only when using the default MBR and
121 won't have any effect if you're using the '--syslinux-mbr' option.
125 Do not output anything but just errors on console.
129 Do not install /boot/addons/ files (like dos, grub, memdisk,...).
131 *\--remove-bootoption=...*::
133 Remove specified bootoption (could be a regex) from existing boot options. Use
134 multiple entries for removing different bootoptions at once. (Note: this option
135 is not support in grml2usb-compat.)
137 *\--skip-grub-config*::
139 Skip generation of grub configuration files. By default the configuration
140 files for syslinux *and* grub will be written so you've a working configuration
141 file no matter whether you're using grub or syslinux as bootloader.
145 Do not touch/install the master boot record (MBR).
147 *\--skip-syslinux-config*::
149 Skip generation of syslinux configuration files. By default the configuration
150 files for syslinux *and* grub will be written so you've a working configuration
151 file no matter whether you're using grub or syslinux as bootloader.
155 This option is deprecated and is being left only for backwards compatibility
156 reasons. Syslinux is the default bootloader of grml2usb and therefore the
157 '--syslinux' option doesn't have any effects. If you do not want to use syslinux
158 as bootloader consider using the '--grub' option.
162 Install syslinux' master boot record (MBR, which is booting from the partition
163 with the "active" flag set) instead of the default one. If you encounter any
164 problems with the default MBR you can try using the syslinux MBR instead. If
165 that works for you please <<author,let us know>> so we can adjust our default
168 //////////////////////////////////////////////////////////////////////////
171 Install specified squashfs file instead of the default.
172 [Notice: not implemented yet.]
173 //////////////////////////////////////////////////////////////////////////
175 //////////////////////////////////////////////////////////////////////////
178 Uninstall grml ISO files.
179 [Notice: not implemented yet.]
180 //////////////////////////////////////////////////////////////////////////
184 Return version and exit.

268 Developers Debugging Hints
269 ~~~~~~~~~~~~~~~~~~~~~~~~~~
271 To play with grml2usb you can avoid using a real device via a loopback file
274 # dd if=/dev/zero of=~/loopback bs=1M count=100 # adjust size to your needs
275 # losetup /dev/loop1 ~/loopback
277 Then create according partitions either running for example:
279 # echo -en "n\np\n1\n\n\nt\n6\na\n1\n w\n" | fdisk /dev/loop1
283 # parted /dev/loop1 -s "mkpart primary fat16 0 -1s mkfs 1 fat16"
285 Finally create a filesystem and execute grml2usb as needed:
287 # mkfs.vfat /dev/loop1
288 # grml2usb --bootloader-only /grml/isos/grml-small_2009.10.iso /dev/loop1
290 [[performance-tracing]]
294 # blktrace -d /dev/sdX -o - | blkparse -i -
295 # grml2usb grml_2009.10.iso /dev/sdX1
298 Troubleshooting and Pitfalls when booting
299 -----------------------------------------
301 Here is a list of common error messages from BIOS/bootloader when trying to boot
304 ///////////////////////////////////////////////////////////
305 TODO: better list type for the error message / reason part?
306 See http://www.methods.co.nz/asciidoc/userguide.html
307 ///////////////////////////////////////////////////////////
310 *Error message*:: ran out of input data. System halted
312 *Reason*:: Everything OK, except for the filesystem used on your usb device. So
313 instead of fat16 you are using for example fat32. Fix: use the appropriate
314 filesystem (fat16 for usb pens usually). The Bootsplash might be displayed, the
315 kernel loads but you very soon get the error message.
317 *Error message*:: Invalid operating system
319 *Reason*:: the partition layout is not ok. Very probably there's no primary
320 partition (/dev/sdX{1..4}) or none has the flag 'bootable' set.
322 *Error message*:: Boot error.
324 *Reason*:: Some BIOSses offer different modes for USB booting. The proper mode
325 to boot a USB stick is USB-HDD. If that doesn’t work or is not supported by your
326 system, you need to format your USB-Stick as USB-ZIP. To do this, syslinux
327 contains an utility called mkdiskimage, which you can use to re-format your USB
328 stick in USB-ZIP format running 'mkdiskimage -4 /dev/sdX 1 64 32'. Please be
329 aware that this procedure will erase all data on your stick. After executing
330 mkdiskimage just continue installing as usual (grml2usb ... /dev/sdX4). Note
331 that this is not going to work for any device larger than 8 GB, since
332 mkdiskimage only supports 1024c 256h 63s. For a more detailed explanation, refer
333 to /usr/share/doc/syslinux-common/usbkey.txt.
335 *Error message*:: No operating system found.
337 *Reason*:: you forgot to set the boot-flag on the partition. Or there really isn't
338 any operating system at all. :)
340 *Error message*:: kernel-panic: unable to mount root-fs...
342 *Reason*:: Kernel boots but fails to find the root filesystem. The root=
343 argument in your kernel commandline is pointing to the wrong device. Adjust
344 root=..., consider using root=UUID=....
346 *Error message*:: Could not find kernel image: ...
348 *Reason*:: either a broken isolinux/syslinux version or a broken BIOS. Check out
349 whether the vendor provides a BIOS update or if using bootloader grub instead of
350 isolinux/syslinux fixes the problem.
353 Frequently Asked Questions (FAQ)
354 --------------------------------
357 Where can I get grml2usb?
358 ~~~~~~~~~~~~~~~~~~~~~~~~~
360 grml2usb is available as Debian package via link:http://deb.grml.org/[the
361 grml-testing Debian repository].
363 If you do not want to (or can't) use the grml2usb Debian package you can either
364 use the grml2usb git tree running:
366 git clone git://git.grml.org/grml2usb.git
371 or download the provided
372 link:http://grml.org/grml2usb/grml2usb.tgz[http://grml.org/grml2usb/grml2usb.tgz]
373 (link:http://grml.org/grml2usb/grml2usb.tgz.md5.asc[gpg signed md5 hash]).
374 Download and extract the tarball and execute the provided script 'install.sh'.
377 It is *NOT* enough to have just the grml2usb script itself without the according
378 files provided either via the Debian package, the git tree or the file
381 [[grml2hd-vs-grml2usb]]
382 What's the difference between grml2hd and grml2usb?
383 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
385 grml2hd installs a running grml system to a harddisk. When rebooting the
386 harddisk installation can be modified and changes will find their way to the
387 harddisk immediately. grml2usb copies just the compressed chroot filesystem
388 (being the squashfs file), some further informational files and a bootloader to
389 your device. This way you don't need as much space as with a harddisk
390 installation (just a USB device with >=ISO size) and when rebooting the system
391 your changes will be lost (unless you are using the persistency feature, see
392 link:http://wiki.grml.org/doku.php?id=persistency[http://wiki.grml.org/doku.php?id=persistency]).
393 Think of using a better CD version: booting is (usually) faster, you don't need
394 to burn a new CD when a new ISO version arrives (just install the new ISO using
395 grml2usb) and you can carry additional files on a writable medium with yourself.
398 Why can't I just dd the ISO to a USB device?
399 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
401 Well, you can. :) Starting with grml 2009.10 the ISOs are dd-able straight out-of-the-box.
404 Note that ANY existing data on your USB device will be destroyed when
405 using the dd approach.
407 ///////////////////////////////////////////////////////////////////////////////////////////////////
408 Grab a recent grml ISO and use
409 link:http://syslinux.zytor.com/wiki/index.php/Doc/isolinux#HYBRID_CD-ROM.2FHARD_DISK_MODE[isohybrid
410 from the syslinux project]:
412 % isohybrid grml_2009.10.iso
413 ///////////////////////////////////////////////////////////////////////////////////////////////////
415 This allows you to dd the Grml ISO to your USB device (use for example
416 link:http://www.chrysocome.net/rawwrite[rawwrite] if you've just a Windows
417 system available) running:
419 % dd if=grml_2009.10.iso of=/dev/sdX
421 where /dev/sdX is your USB device. Of course this doesn't provide such a
422 flexible system like with grml2usb (no multi-ISO setup, no additional default
423 bootoptions,...) but it's a nice way to get a working USB boot setup if you
424 don't have grml2usb available.
427 What's the difference between grml2usb and just using dd?
428 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
430 grml2usb does not remove any data from your USB device and does not alter the
431 partition table at all. grml2usb provides multi-ISO support, support for adding
432 default bootoptions and selecting the bootloader (syslinux vs. grub) without
433 having to manually touch the ISO at all.
439 grml2iso is a script which uses grml2usb to generate a multiboot ISO out of
440 several grml ISOs. See 'man grml2iso' for further details.
443 grml2usb fails with "Fatal: file default.cfg could not be found."
444 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
446 If you are trying to install an older grml ISO (older than grml 2009.10) with a
447 recent version of grml2usb then you might notice:
449 Fatal: file default.cfg could not be found.
450 Note: this grml2usb version requires an ISO generated by grml-live >=0.9.24 ...
451 ... either use grml releases >=2009.10 or switch to an older grml2usb version.
452 Please visit http://grml.org/grml2usb/#grml2usb-compat for further information
453 Fatal: a critical error happend during execution (not a grml ISO?), giving up
455 Breaking the backward compatibility was necessary to avoid maintainability hell.
456 If you want to install older grml ISOs please use the grml2usb-compat script
457 which provides support for older releases.
460 Why is there a menu.lst and a grub.cfg inside /boot/grub/?
461 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
463 grml2usb supports grub version 1 (grub1) as well as grub version 2 (grub2).
464 Whereas grub1 uses menu.lst the new version grub2 needs grub.cfg.
465 Providing both files allows grml2usb to install grub on the target device
466 no matter which grub version is available on the host where grml2usb is
470 grub-install fails with 'The file ../boot/grub/stage1 not read correctly"?!
471 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
473 Check whether the partition has the right partition type. For example do NOT use
474 FAT16 (partition type 6) when using a ext3 filesystem on the partition but
475 instead use the correct partition type ('83' - Linux) then.
477 [[grub-install-xfs_freeze]]
478 grub-install complains about /sbin/grub-install and/or xfs_freeze?!
479 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
481 The following message:
483 You shouldn't call /sbin/grub-install. Please call /usr/sbin/grub-install instead!
484 xfs_freeze: specified file ["/tmp/tmpqaBK6z/boot/grub"] is not on an XFS filesystem
486 This is "normal". grub-install sends those messages to stderr. To avoid hiding any
487 possible real error messages grml2usb doesn't ignore those messages.
490 grub-install complains about /boot/grub/device.map?!
491 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
493 The following message:
495 grub-probe: error: Cannot open `/boot/grub/device.map'
497 This is "normal" (at least with grub1). This isn't a problem, because the
498 device.map file will be generated on the target device anyway.
501 grub-install complains about a unary operator?!
502 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
504 The following message:
506 '/usr/sbin/grub-install: line 374: [: =: unary operator expected'
508 This is "normal". Just ignore it. (It usually doesn't appear
509 on the second invocation on the same device.)
511 [[unknown-filesystem]]
512 grub-install fails with grub-probe: error: unknown filesystem?!
513 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
515 The following message:
517 grub-probe: error: unknown filesystem
518 Auto-detection of a filesystem module failed.
519 Please specify the module with the option `--modules' explicitly.
521 usually means that the device partition table says something else than the
522 filesystem on the device. For example using FAT16 as filesystem type and
523 using FAT32 as filesystem on the partition will not work. Either set filesystem
524 type to FAT32 or format the partition using FAT16. It is essential that
525 device partition table and filesystem use the same filesystem type.
528 grub-setup fails after Attempting to install GRUB to a partition instead of the MBR?!
529 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
531 The following message:
533 grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea.
534 grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and its use is discouraged.
535 grub-setup: error: Cannot read `/grub/core.img' correctly
537 appears when using grub2 versions older than 1.98 as those version introduced a
538 regression which avoids that grub is being installed into a partition (PBR,
539 Partition Boot Record) instead of MBR (Master Boot Record).
541 To work around this issue you can either 1) upgrade to grub versions >=1.98, 2)
542 install grub into the MBR (Master Boot Record) using the '--grub-mbr' option of
543 grml2usb or 3) switch to syslinux as bootmanager (just drop the '--grub'
547 I'm getting something like "Error: /usr/share/grml2usb/grub/splash.xpm.gz can not be read"!?
548 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
550 Looks like you've only the grml2usb script itself available. Please make sure
551 you've the grml2usb Debian package installed. The most resent stable version is
552 available via link:http://deb.grml.org/[the grml-testing Debian repository]. If
553 you do not have a Debian system please see section <<download,Where can I get
554 grml2usb?>> in this FAQ.
557 Why do I have to use a FAT16/FAT32 filesystem?
558 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
560 Syslinux (currently) does not support any other filesystems besides FAT16/FAT32
561 (though that's a sane default if you want to share your files with other
562 (operating) systems). If you want to use a different filesystem (like ext2/3)
563 use the bootloader grub instead using grml2usb's '--grub' option.
566 FAT32 is supported since syslinux version 3.0.
569 Addons -> Hardware Detection Tool freezes
570 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
572 This usually means that the machine you ran grml2usb on had syslinux 3.x
573 installed. The version of hdt (Hardware detection tool) shipping with Grml
574 2010.12 and newer requires syslinux 4.x.
577 I think I've got a really cool idea!
