Booting A Linux Console From An External FLASH Drive TBJLT136 Introduction Vista T4, T2, and I3 consoles may be booted from an external drive if the internal drive is nonfunctional and it is required to use the console, or to retrieve data from the internal hard drive prior to re-isoing. Application All vista Linux consoles. Parts required ■ ■ ■ 4 GB or bigger USB FLASH drive. This drive will be erased/re loaded. Vista ISO CD v1.13 or later (T2/T4 only) Vista ISO USB v1.13 or later (I3 only) Procedure for T4/T2 1. Plug the USB stick into a console USB port. 2. Boot the console and insert the source CD. 3. Follow the normal procedure to re-iso the console, however in the “Select disk to install system to” dialogue select the USB drive as the destination. 4. Iso the console as usual. This takes significantly longer than normal due to the fact that the data is being written to the much slower USB drive. 5. At the conclusion power down the console and remove the CD, leaving the USB drive present. 6. Power the console again and allow it to boot from the USB drive. Note that the Boot Drive Priority” may need to be adjusted in the console BIOS. Procedure for I3 The procedure for the I3 is almost identical to that for the T4/T2, except that instead of using a source CD the source is another USB drive. Mounting the Drive Once the console has booted it is necessary to mount the hard drive to access it. To mount the hard drive: 1. Press CTRL + ALT + F4 to go into the maintenance screen. 2. Type sudo mkdir /xxx [enter] to make a temporary directory xxx to mount the drive to. 3. Type mount[enter]. The mount command will return some text – refer to the top line of this text which will show the boot drive eg /dev/sda1 or /dev/sdb1. In the next step use the device that is not already mounted. 4. Type sudo mount /dev/sda1 /xxx[enter] or sudo mount /dev/sdb1 /xxx[enter], depending on eth results of step 3. This will mount the hard drive data directory to the /xxx directory. The hard drive can now be accessed via the /xxx directory.
