I shot myself in the foot today. I had a centos 5.11 install running fine. Doing a backup, I overwrote the /bin directory by mistake.
I couldn't get my machine to recognize a centos 6.5 or 6.6 install dvd, so I put in the original centos 5.10 install disc and re-installed. No problem. During the text installer, I told it to install grub on /dev/sdc1, which is /boot. My raid arrays with lots of data (still intact) are /dev/sda and /dev/sdb, so I didn't want it to install grub on the MBR of /dev/sda.
When I power it on, the kernel selection comes up, I select the (only) kernel and it says: Booting 'Centos (2.6.18-371.el5)'
root (hd2,0) filesystem type is ext2fs, partition type is 0x83 kernel /vmlinuz-2.6.18-371.el5 ro root=LABEL=/ rhgb quiet
Error 15: file not found
Press any key to continue
So it is finding the /boot/grub/grub.conf and reading it correctly. /boot (/dev/sdc1) actually contains the vmlinux-2.6.18-371.el5 file as well as all the other related files that belong there.
I installed onto the same hard disk that the last OS was on, reformatting the /, /boot, /usr partitions and installing to them. /boot is /dev/sdc1 and / is on /dev/sdc5. No errors or problems in the install.
should the root (hd2,0) line above actually read root (hd2,4) where the real / partition is (/dev/sdc5)??
I booted linux rescue with the 5.10 install disk, and I see that the /boot/grub/grub.conf file looks correct, and all the correct files are there in /boot. I am confused and don't know what to do next.
