Solving GPT problem during the linux installation on CentOS5.6

After partitioning the disks when I installed CentOS 5.6, it gave me the following error message:
“Your boot partition is on a disk using the GPT partitioning scheme but this machine cannot boot using GPT”.
I searched the solution on the net, and someone said the protected MBR GPT partition entire needs to be deleted.
So I entered the rescue mode and deleted the MBR on the disks as below.
# dd if=/dev/zero of=/dev/sda bs=512 count=1
I reinstalled the system again, it worked.

  10. ys it worked for the install oracle Linux 5.5 in the IMB H22

  11. why not use the latest version 6.3 Centos. it installs ok decide in advance what partitions you want. you only need lots of partitions if you want to keep separate images why not just have /, /home, and a swap

  24. Appreciating the commitment you put into your website and detailed information you
    present. It’s great to come across a blog every once in a while
    that isn’t the same old rehashed information.
    Wonderful read! I’ve bookmarked your site and I’m adding your RSS feeds to my Google account.

    • Why am I on this email list?

      Please remove me.

  25. thanks! conchetumare

    • thats so funny man you made my day. By the way if the command above doesn’t work for some of you I used CD loading utility called Knoppix. If you go to accessories and look for Disk Utilities format the drive using EXT 4 and problem surely to be resolved. They have various format utilities and options.

  26. thanks it was of great help. F12 worked for me.
