|
<p>Until recently installing <b>Clonezilla-SysRescCD</b> on a USB disk would not be such a great idea, because of its size. But since USB devices become cheaper and cheaper, it is an interesting alternative.<br><br> |
| 110 |
|
|
<!--emty-line--> |
| 111 |
|
|
Starting with <b>version 3.1.0</b>, <b>Clonezilla-SysRescCD</b> provides an iso file that's ISO-Hybrided. This means (as we read at <a href="http://syslinux.zytor.com/wiki/index.php/Doc/isolinux#HYBRID_CD-ROM.2FHARD_DISK_MODE" target="_blank">the isolynux site</a>) that</p> |
| 112 |
|
|
<!--emty-line--> |
| 113 |
|
|
<p class="otherpage">"the iso file can be booted from either CD-ROM or from a device which BIOS considers a hard disk or ZIP disk, e.g. a USB key or similar. This image can then be copied using any raw disk writing tool (on Unix systems, typically "dd" or "cat") to a USB disk, or written to a CD-ROM using standard CD burning tools.<br> |
| 114 |
|
|
<br> |
| 115 |
|
|
The ISO 9660 filesystem is encapsulated in a partition (which starts at offset zero, which may confuse some systems.) This makes it possible for the operating system, once booted, to use the remainder of the device for persistent storage by creating a second partition."</p> |
| 116 |
|
|
|
| 117 |

<div align="center"><table class="note" border="0" cellpadding="20"><tr><td valign="top"><img src="images/important.png"></td><td> |
| 119 |
|
|
Incorrect use of any raw disk writing tool could cause your<br> operating system (GNU/Linux / Windows) <b>not to boot</b>.<br><br> Confirm the command before you run it.<br></td></tr></table></div> |
| 120 |
|
|
|
| 121 |
|
|
<p>So, from any linux box, assuming <b>Clonezilla-SysRescCD</b> iso file is in your home directory, and your USB device name is <b><font color="Green">sdc4</font></b>, you just execute the commands:</p> |
| 122 |
|
|
|
| 123 |
|
|
<p class="newcode">umount /dev/<font color="Green">sdc4</font><br> |
| 124 |
sng |
77 |
dd if=~/clonezilla-sysresccd-full-mod-"myVersion".iso of=/dev/<font color="Green">sdc</font> bs=512</p> |
| 125 |
sng |
28 |
|
| 126 |
|
|
<p>And that's it. Your usb device is ready to boot!!!</p> |
| 127 |

<!--emty-line--> |
| 131 |
|
|
<p>If the "easy" way does not work there is an alternative; you will use the <b>Clonezilla-SysRescCD</b> ISO file (or CD) to copy and modify a couple of files on the USB disk, and finally make it bootable, using <a href="http://syslinux.zytor.com" target="_blank">syslinux</a> and its configuration file <b>syslinux.cfg</b>.</p> |

| 135 |
|
|
<!--emty-line--> |
| 136 |
|
|
<p>The only thing that's important is that your USB disk must contain a VFAT (Windows 98 or DOS) file system. If this is not the case, refer to the section "<a href="#trouble">Troubleshooting</a>", to find out how you can format it, before copying files to it.<br><br> |
| 137 |
|
|
<!--emty-line--> |
| 138 |
|
|
The bootable USB disk creation procedure can be performed either from Linux or Windows.</p> |

If you want to create a bootable USB flash drive for this version<br> |
| 142 |

|
or later, remember to use the syslinux command from <b>syslinux<br> |
| 143 |

| 146 |
|
|
<p>There are two ways you can proceed, if you are going to use Linux to perform the USB installation, either using a running linux box, or using <b>Clonezilla-SysRescCD</b>.<br><br> |
| 147 |
|
|
<!--emty-line--> |
| 148 |
|
|
I will assume that you have saved <b>clonezilla-sysresccd-full-mod-3.1.0.iso</b> in your home directory (<b><font color="Green">~</font></b>).</p> |

<H3><a name="lin-box"></a>Using a linux box [<a href="#usb-top" title="go to top of the page">^</a>]</H3> |
| 151 |
|
|
<p>If you already have a linux box up and running, you can use it to create your <b>Clonezilla-SysRescCD</b> USB, without even having to burn it to CD beforehand. The only thing here is that you have to have <a href="http://syslinux.zytor.com" target="_blank">syslinux</a> installed.<br><br> |
| 152 |
|
|
<!--emty-line--> |
| 153 |
|
|
I will assume that your CD drive is <b>/dev/<font color="Green">sr0</font></b> and that your USB device is <b>/dev/<font color="Green">sdc4</font></b>. You may have to change any of them to reflect your system configuration.<br><br> |
| 154 |
|
|
<!--emty-line--> |
| 155 |
|
|
Boot into linux, connect your USB device and execute the following commands:</p> |
| 156 |
|
|
<p class="newcode">mkdir /mnt/mycd<br> |
| 157 |
|
|
mount <font color="Green">~</font>/clonezilla-sysresccd-full-mod-3.1.0.iso /mnt/mycd -o loop<br> |

|
<div align="center"><table class="note" border="0" cellpadding="20"><tr><td valign="top"><img src="images/important.png"></td><td> |
| 169 |
|
|
Since you are using any linux box to complete this procedure,<br>you have to use the syslinux installation provided by this linux box.<br><br>Otherwise, you will probably end up with an unbootable device...</td></tr></table></div> |
| 170 |
|
|
|
| 171 |
|
|
<p>First thing you have to do is find where syslinux is installed. The best way to do that is look for a file named <b>vesamenu.c32</b>. You can use locate, find, or any other distribution specific tool for that. In Debian (and its derivatives like Ubuntu, LMDE etc.) this file is under <font color="Green"><b>/usr/lib/syslinux</b></font>, so I'll just use that for the following code.</p> |
| 172 |
|
|
|
| 173 |
|
|
<p class="newcode">cd syslinux<br> |
| 174 |
|
|
for f in *.c32<br> |
| 175 |
|

do<br> |
| 176 |

cp -v <font color="Green"><b>/usr/lib/syslinux</b></font>/$f .<br> |

cd ..<br> |
| 178 |
|
|
done</p> |
| 179 |
|
|
|
| 180 |
|
|
<p>In either case, unmount the device and delete the mount point (directory).</p> |
| 181 |
|
|
|
| 182 |
|
|
<p class="newcode">cd; umount /dev/<font color="Green">sdc4</font><br> |

sng |
28 |
rmdir /mnt/usbdevice</p> |
| 184 |
|
|
<!--emty-line--> |
| 185 |
|
|
<p>Finally make your USB device bootable, by executing</p> |
| 186 |
|
|
<p class="newcode">syslinux /dev/<font color="Green">sdc4</font></p> |
| 187 |

<p>Installing <b>Clonezilla-SysRescCD</b> from Windows is as easy as it is in Linux. You have to burn <b>Clonezilla-SysRescCD</b> to CD or use a CD/DVD ROM emulator software like <a href="http://www.daemon-tools.cc/dtcc/announcements.php" target="_blank">Daemon Tools</a> to mount the ISO file.<br><br> |
| 216 |
|
|
<!--emty-line--> |
| 217 |
|
|
I will assume that your USB device is drive <b><font color="Green">K:</font></b> and your CD drive or mounted ISO file is drive |
| 218 |
|
|
<b><font color="Green">D:</font></b>. You may have to change any of them, in order to reflect your system configuration.<br><br> |
| 219 |
|
|
|
| 220 |
|
|
You will have to</p> |
| 221 |
|
|
|
| 222 |
|
|
<ul> |
| 223 |
|
|
<li>Copy all files from drive <b><font color="Green">D:</font></b> (CD or mounted ISO file) to drive <b><font color="Green">K:</font></b> (USB disk)</li> |
| 224 |
sng |
181 |
<li>Copy <b><u>all</u> cfg</b> files from <b><font color="Green">K:\</font>syslinux</b> to <b><font color="Green">K:\</font>isolinux</b></li> |
| 225 |
|
|
<li>Copy <b><u>all</u> png</b> files from <b><font color="Green">K:\</font>syslinux</b> to <b><font color="Green">K:\</font>isolinux</b></li> |
| 226 |
|
|
<li>Delete the folder <b><font color="Green">K:\</font>syslinux</b></li> |
| 227 |
|
|
<li>Rename <b><font color="Green">K:\</font>isolinux</b> to <b><font color="Green">K:\</font>syslinux</b></li> |
| 228 |
sng |
28 |
</ul> |
| 229 |
|
|
<p>Now all you have to do is make your USB disk bootable. In order to do that you have to open a DOS window (in Windows XP press "<b>Start / Run </b>" and type <b>cmd</b>). Then type at DOS prompt:</p> |
| 230 |
|
|
<p class="newcode"><font color="Green">K:</font><br> |

| 236 |
|
|
<p>Before trying to boot from your USB device, you have to set your boot device at your BIOS. This means you have to reboot having your USB device connected, get into your BIOS (usually pressing DEL) and make the appropriate settings in the BOOT section.<br><br> |
| 237 |
|
|
<!--emty-line--> |
| 238 |
|
|
Booting <b>Clonezilla Live</b> should not be a problem. Just select the desired option and press ENTER to boot.<br><br> |
| 239 |
|
|
<!--emty-line--> |
| 240 |
|
|
Booting <b>SystemRescueCD</b> has been made equally simple with <b>SystemRescueCD v 1.0.0</b>, so you shouldn't have any problem (option <b>cdroot</b> is not required any more).<br><br> |
| 241 |
|
|
<!--emty-line--> |
| 242 |
|
|
If you have any problems here, you may try adding any of these boot parameters:</p> |

|
<p>Whether you can successfully boot from a USB disk or not, depends mainly on your BIOS. Chances are that you will not be able to boot on an old computer, with an old (and possibly buggy) BIOS. So I would recommend testing your <b>Clonezilla-SysRescCD USB</b> on a new computer.</p> |

or <b>Clonezilla Live does not boot</b><br> |
| 255 |

|
<!--emty-line--> |
| 256 |
|
|
The first thing you should do is double check your BIOS settings. Reboot having your USB device connected, get into your BIOS (usually pressing DEL) and make the appropriate settings in the BOOT section.<br><br> |
| 257 |
|
|
<!--emty-line--> |
| 258 |
|
|
If you are on linux, check that the partition on the USB disk is active (bootable), executing:</p> |
| 259 |
|
|
<p class="newcode" style="margin-left: 0;">fdisk -l /dev/<font color="Green">sdc</font></p> |
| 260 |

| 329 |
|
|
<p>As stated previously, <b>Clonezilla-SysRescCD USB</b> is booted by <b>syslinux</b> through its configuration file <b>syslinux.cfg</b>. This file loads <b>sysresc.cfg</b> in order to boot <b>SystemRescueCD</b>.<br><br> |
| 330 |
|
|
<!--emty-line--> |
| 331 |
|
|
If you have to specify any additional boot parameters for <b>SystemRescueCD</b>, you may want to write these changes to the configuration file, so that you don't have to insert them by hand every time.<br><br> |
| 332 |
|
|
<!--emty-line--> |
| 333 |
|
|
The procedure to do that is the following:<br><br> |
| 334 |
|
|
<!--emty-line--> |
| 335 |
sng |
181 |
Boot <b>SystemRescueCD</b> (or if that's not possible yet, boot <b>Clonezilla Live</b> and get to the command line) using the option <b>To RAM</b>, and when it is fully loaded, execute the following commands:</p> |
| 336 |
sng |
28 |
<p class="newcode">mkdir /mnt/usbdevice<br> |
| 337 |
|
|
mount /dev/<font color="Green">[device]</font> /mnt/usbdevice <br> |
| 338 |
|
|
cd /mnt/usbdevice<br> |
| 339 |
|
|
cp sysresc.cfg sysresc.bak<br> |
| 340 |
sng |
181 |
sed 's|<font color="Red">scandelay=5</font>|<font color="Red">scandelay=<font color="Green">x</font> [additional params]</font>|' \<br> |
| 341 |
sng |
28 |
sysresc.cfg > sys.cfg<br> |
| 342 |
|
|
mv sys.cfg sysresc.cfg<br> |
| 343 |
|
|
cd; umount /dev/<font color="Green">[device]</font><br> |
| 344 |
|
|
syslinux /dev/<font color="Green">[device]</font><br> |
| 345 |
|
|
reboot</p> |
| 346 |
|
|
<!--emty-line--> |
| 347 |
|
|
<p>where <b><font color="Green">x</font></b> is a number from 1 to 10.</p> |
| 348 |
|
|
<!--emty-line--> |
| 349 |
|
|
<p>After executing these commands, you will have a new <b>sysresc.cfg</b> file, and a backup file called <b>sysresc.bak</b> (in case things go wrong).<br><br> |
| 350 |
|
|
<!--emty-line--> |
| 351 |
|
|
If, for example, you want to increase the device scan delay to maximum, the above commands would become:</p> |
| 352 |
|
|
<p class="newcode">mkdir /mnt/usbdevice<br> |
| 353 |
sng |
181 |
mount /dev/<font color="Green">sdc1</font> /mnt/usbdevice <br> |
| 354 |
sng |
28 |
cd /mnt/usbdevice<br> |
| 355 |
|
|
cp sysresc.cfg sysresc.bak<br> |
| 356 |
|
|
sed 's|<font color="Red">scandelay=5</font>|<font color="Red">scandelay=<font color="Green">10</font></font>|' sysresc.cfg > sys.cfg<br> |
| 357 |
|
|
mv sys.cfg sysresc.cfg<br> |
| 358 |
sng |

cd; umount /dev/<font color="Green">sdc1</font><br> |
| 359 |

syslinux /dev/<font color="Green">sdc1</font><br> |
| 360 |
sng |
28 |
reboot</p> |
| 361 |
|
|
<!--emty-line--> |
| 362 |
|
|
<p>If, in addition to that, you had to use the boot parameter <b><font color="Red">usbstick</font></b>, then it would be:</p> |
| 363 |
|
|
<p class="newcode">mkdir /mnt/usbdevice<br> |
| 364 |
sng |
181 |
mount /dev/<font color="Green">sdc1</font> /mnt/usbdevice <br> |

sng |
28 |
cd /mnt/usbdevice<br> |

| 367 |
|
|
sed 's|<font color="Red">scandelay=5</font>|<font color="Red">scandelay=<font color="Green">10</font> usbstick</font>|' sysresc.cfg > sys.cfg<br> |
| 368 |
|
|
mv sys.cfg sysresc.cfg<br> |
| 369 |
sng |
181 |
cd; umount /dev/<font color="Green">sdc1</font><br> |
| 370 |

|
syslinux /dev/<font color="Green">sdc1</font><br> |
| 371 |
sng |
28 |
reboot</p> |
| 372 |
|
|
<!--emty-line--> |
| 373 |
|
|
<p>In case something goes wrong with your new settings, you can always rename <b>sysresc.bak</b> to <b>sysresc.cfg</b>, either from linux or Windows.</p> |
