I want to install CentOS 6.4 on HP DL380 G4 server. First of all I select install or upgrade an existing system, but it boot something like without graphic (like basic video card). My main problem is in partitioning type: it shows this and won't let me custom partitioning:                              |partitioning type|installation require partitioning of your hard drive. the default layout is suitable for most users. select what space to use and which drive to use as the install layout                          Use entire drive                          Replace existing Linux system                          Use free space              [*] cciss/c0d0 .... MB (compaq amart arrey)                           OK                 BACK I want to manually make the partitioning myself, but selecting each one of them don't let me to do that. What to do?

This is called Text mode installation Program. Anaconda also have a text-base installation apart of the graphical installation. If one of the following situation occurs the installation will use text-mode.The installation system fails to identify the display hardware on your computer.You choose the text mode installation from the boot menu.I didn't choose text mode myself, I think the installation has failed to identify the display hardware because I use a KVM to use the server. There is some differences between graphical installation and text-mode (I don't know why there should be difference between them ). Differences are:configuring advanced storage methods such as LVM, RAID, FCoE, zFCP, and iSCSI. customizing the partition layoutcustomizing the boot loader layout selecting packages during installation configuring the installed system with first bootfor this problem i selected the second one (Install system with basic video card ) and the problem solved and the graphical installation came up with all options. I think in HP DL380 G4 the video card is weak or the installation can not recognize it so it use text-mode installation. but with basic video card my problem solved.Some related information:We can configure options that are not available in text-mode with boot options. see this link.
