here to start the installation of the U -disk production completed.

Three: Test Startup disk Availability:

You can use the virtual machine or the real machine to Enter the installation interface with the U-disk, using wmware virtual machine mode.

because the WMware virtual machine does not support u -disk booting, you can add a physical hard disk to the virtual host and point to the u -disk .

Add a hard disk

Installation considerations:

1 : When partitioning, be careful to select only the hard disk partition, USB partition is removed, (same as when assigning other partitions) such as:

2 : Using USB installation Linux system, the default Grub installed in USB change the mounting position to the hard drive, or unplug the USB , the system will not boot so that it cannot enter the system. The steps to change are as follows:

Go to the grub advanced option and select "Change Drive Order" to put the /dev/sda Position up so that it becomes the first identified installation location.

with the above configuration, grub is installed to the hard disk partition.

At this time pull out the U -disk, found that the system can be normal guidance, the "other" here refers to the USB boot option, you can edit the grub.conf file after entering the system to delete the option
