Preparation:
(1).RHEL5 64-bit Installation Disks (6 CDs, ISO format)
(2).A USB Flash Disk (>=32M)
(3).Linux/Unix system
Key Points:
+ Boot with USB drive;
+ Install from hard disk ISO images;
Steps:
+ Create a USB boot drive.
Mount CD1. Copy bootdisk.img from image/ directory. Write it to USB drive.
In FreeBSD,
dd if=diskboot.img of=/dev/da0s1
+ Make sure that you have a FAT32 partition, cay D:. Place RHEL5 images in one directory, say D:\RHEL5\.
+ Boot from USB disk, select Hard disk as installation media. You should choose correct partition and type exact path name where RHEL5 images are placed.
+ Now, let's go. Be sure to install Grub in correct place (MBR is a good choice). I put it in the boot section of RHEL5 partition, then active it, but got an "Grub geom error". Then install it on MBR works.
