Post by xtdz32 » 2018/04/12 12:11:49

Greetings ,
I am trying to install cent OS 6.8 on a HP gen 9 blade server.

i tried loading from the grub, but i think i am geting the comman wrong.
here's my process
grub> root (hd0,1)
grub> Kernel /vmlinuz-2.6.32-642xxxxxx root=<sda,sdb>
grub> initrd /initrdxxxxxx
grub> boot


after typing this, i get an erro in the process. how do i identify the label for root=<Label>

Thanks for your support

Is your machine in UEFI or Legacy BIOS mode? CentOS 6 has very limited support for UEFI systems and none at all for secure boot.

Also, don't use 6.8, it's out of date. The latest (and probably last) CentOS 6 is 6.9.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

If you installed CentOS 6.8 then make sure to run yum update ASAP as tehre are numerous high severity security problems in 6.8 that are not fixed until you update.
