Have Adaptec RAID controller. There're 4 hdds on it. Existed Centos 5.10 on:/dev/sda1 - /boot ext3/dev/sda2 - LVMI decided to migrate to Centos 7 and installed It on:/dev/sdd1 - /boot XFS/dev/sdd2 - LVMSo...As far As I can't choose disk boot priority due to RAID, How can I point BIOS to boot mbr from /dev/sdd (Centos 7). Also we need to keep in mind that Centos 5 - Grub 0.9 and Centos 7 served by Grub2.Any help would be appreciated. Thanks.
