How to deal with centos installation that does not support GPT Mode

Tip:

Your Boot partition is on a disk using the GPT partitioning scheme but this machines cannot boot using GPT.

After xenserver is installed, You need to reinstall centos 5.x. When partitioning, the system reports the following prompt: GPT is not supported and cannot be partitioned. This is a successful experience. I found it online:

Use the shortcut key CTRL + ALT + F2 to go to the command interface:

View the device name of the hard disk:

Fdisk-l

 

Assume that the type displayed after/dev/SDA is GPT. input:

Parted

Enter:

Select

 

Enter:

/Dev/SDA (do not select sda1 or sda2 or something, just enter SDA)

Input: mklabel msdos

Input: Yes

Your disk type? [GPT]?

Input:

Msdos (important)

Quit

Restart the server,

Reformat the disk to be installed and install it.
