Installing Oracle Linux6.3 from hard drive

Introducing from the hard drive installation of OracleLinux6.3: This blog post focuses not only on installing OracleLinux6.3, but also on a small error that has plagued me for several days. www.2cto.com scene: A blank hard disk, a tool U disk, disk image: OracleLinux-R6-U3-Server-x86_64-dvd.iso steps: use the tool U disk, do the following aspects: to partition the blank hard disk, /dev/sda1 50G fat32 format;/dev/sda2 50G Ext4 format [do not need to divide]; the latter is not divided for the time being. install grub boot to the/dev/sda1 partition and write the menu. the content of the lst file is as follows: www.2cto.com default 0 timeout 5 title Oracle Linux Installroot (hd0, 0) kernel/vmlinuz iso-scan/filename =/OracleLinux-R6-U3-Server-x86_64-dvd.iso root =/dev/sda1 ro quiet initrd/initrd. img releases files "vmlinuz" and "initrd. img and OracleLinux-R6-U3-Server-x86_64-dvd.iso are placed under the root directory of/dev/sda1. start installation: Theoretically, there should be no errors. many people may install the system smoothly. however, I was not so lucky. After my computer was initially loaded, the cursor would be at the leftmost end of the row in the middle of the screen and would not move any more. later, I switched the virtual desktop to desktop 4 (Ctrl + Alt + F4), and I saw an error similar to the following:
