Troubleshooting and Pitfalls when booting
*Reason*:: the partition layout is not ok. Very probably there's no primary
partition (/dev/sdX{1..4}) or none has the flag 'bootable' set.
+*Error message*:: Boot error.
+
+*Reason*:: Some BIOSses offer different modes for USB booting. The proper mode
+to boot a USB stick is USB-HDD. If that doesn’t work or is not supported by your
+system, you need to format your USB-Stick as USB-ZIP. To do this, syslinux
+contains an utility called mkdiskimage, which you can use to re-format your USB
+stick in USB-ZIP format running 'mkdiskimage -4 /dev/sdX 1 64 32'. Please be
+aware that this procedure will erase all data on your stick. After executing
+mkdiskimage just continue installing as usual (grml2usb ... /dev/sdX4). Note
+that this is not going to work for any device larger than 8 GB, since
+mkdiskimage only supports 1024c 256h 63s. For a more detailed explanation, refer

[[grml2usb-vs-dd]]
What's the difference between grml2usb and just using dd?
grml2usb does not remove any data from your USB device and does not alter the
partition table at all. grml2usb provides multi-ISO support, support for adding

several grml ISOs. See 'man grml2iso' for further details.
