I. USB flash drive

II. Install.
1. restart the computer, press the "del" key to enter the bios, select the second option, change the hard disk to the USB flash drive, and change the first boot to hardisk.
Then restart the computer.
For different machines, the keys for entering the bios are different. For some machines, press "F2", and for others press "del". For break cases, refer to the motherboard manual or consult experts.

2. After restarting the computer, the computer starts from the USB flash drive. after entering the installation interface of Red Hat Enterprise 5.4, press the "F2" key and enter: linux askmethmod
3. After a series of programs run, the installation dialog box appears. Select the source of the installation as the hard disk (that is, the USB flash disk), usually starting with sd.
4. After completing the above steps, just like installing the CD, partitioning, selecting the installation type, and so on.

Some netizens recently reported that after installing the linux system, if the USB flash disk is pulled out, the system cannot be guided. The reason for this is: red hat installs the grub boot loader on a USB flash drive (usually/dev/sdb), instead of a hard disk (/dev/sda), and uses advanced boot options when partitioning the system, change the boot sequence of the hard disk.

The following is my grub configuration process (step 4 ):

1. Use a custom structure to change the drive sequence ()

2. Here we only create three partitions/boot: 128 M swap: 1024 M/: all available space.

3. If the Grub boot loader is installed on/dev/sdb, the system cannot be booted after the USB flash drive is pulled out .!!

Follow these steps to change the grub boot sequence and select "Configure advanced Boot Loader options". click Next.

4. Click to change the drive sequence. Generally, sda is a hard disk and sdb is a USB flash disk. Move/dev/sda up.
