Hello all, I am attempting to install CentOS 5.5 on a recently donated home server (was Windows). I've tried installing twice; first, separating /boot, swap, /, /var, /usr and /home into different partitions, the second time choosing default layout. Both times have resulted in "GRUB Hard Disk Error" upon boot. About the hard disk, it is a Seagate SATA drive. I do not have another drive to configure RAID. The BIOS is set to: Onboard PATA/SATA Adapters = Both SATA mode = IDE Onboard PATA/SATA Cofiguration = Enhanced Mode (???) Upon booting into rescue mode, the file systems mount successfully and I am able to read data from files. The current file structure is (default layout): /boot / swap grub.conf: #boot=/dev/sda1 default=0 timeout=5 splashimage=(hd1,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-194.el5) root (hd1,0) kernel /vmlinuz-2.6.18-194.el5 ro root=/dev/VolGroup00/LogVol00 initrd /initrd-2.6.18-194.el5.img title Other rootmoverify (hd0,0) chainloader +1 This is brand new from the installation. My questions are, what am I missing? Bad configuration? Should boot=/dev/sda1 really be commented out? Some pointers for manually installing and configuring grub would be great, as I am lacking experience in that area. Any idea as to what is going on would be great! Thanks in advance, Rob -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/centos/attachments/20100919/37b7fa6d/attachment-0004.html>
