CentOS Linux when GPT partitions fail to boot the wrong solution

Install system: When CentOS 5.9_64bit, after partitioning, prompts the following error.

Workaround:

1. Press CTRL+ALT+F2 to enter the command line
2. First view the partition SH #fdisk-L
The following assumption partitions are/DEV/SDA
3. Modify the Label

(parted) SELECT/DEV/SDA
(parted) Mklabel//hint default is GPT, enter MSDOS, carriage return
(parted) print//view to MSDOS, which means it's successful.
(parted) Quit/exit
Sh#fdisk-l//reconfirm, no GPT tags are visible

4. Press CTRL+ALT+F6 to return to the GUI, point "back", then click "Next" to re-enter the partition interface.
