Hi, I am new to the community and look for some help for installing CentOS on my Dell poweredge t420 server. I am installing the CentOS on dual boot; already have the windows server 2008 installed via UEFI. I installed the CentOS 6.3 via UEFI DVD boot too, and because my server have the hardware RAID, so instead of the LVM, I use standard partition for all my partitions. The installation completed successfully and I let the installer write the boot info into the EFI boot partition. Reboot the machine after installation complete, but got kernel panic issue when loading the OS. I saw some message like this: Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init Not tainted blablba version BTW, don't want to make thing complicated, but curious if the partition might be a issue here(whether type, or the order of the partition) The weird thing is before I installed the centOS using standard partition, I by chance, chose "use free space" for create the partition to install the OS once, and the system automatically help me create the LVM and OS was working fine. After that I format the harddisk and want to install it again using standard partition, and it failed. Thanks for any help. I could provide more debug info, just let me know how. Lewis
