rescuecd root=/dev/sda6to start it. Keep in mind that you must use a 64bit kernel if your system is made of 64bit programs. This option works with LVM volumes. Use
rescuecd root=/dev/VolGroup00/LogVol00. Support is also provided for
root=auto, which scans all the block devices tfor a linux system. The first linux system found will be started. So with
root=autolet you start the system installed from the CD-ROM in case you have problem with your boot loader or kernel. It's also possible to specify a partition using its
filesystem uuid. If the label of the partition where linux is installed is
mylinux, then boot it using
rescuecd root=LABEL=mylinux. Similarly
root=UUID=b3d3bec5-997a-413e-8449-0d0ec41ccba7. See more details.

Network boot using PXE
SystemRescueCd provides several options for booting from the network using PXE.
