Yesterday I installed a new kernel - kernel-2.6.22.5-76.fc7 (installed via rpm -ivh - I never remove old kernels until I am *sure* that the new one is OK). That is the ONLY new package I have installed since the last reboot (about a week ago). This morning I had to reboot (I wanted to install a new video card), and I did so ... but then remembered something I had to do first, so I just let the reboot cycle continue. New problem: grub no longer boots the system. I tried again after full power-down. Same result. Eventually after the usual HW/bios startup messages I get a black screen, and the word GRUB appears. Then several seconds another GRUB is added. I let this run while I ran an errand - and it continued that way "GRUB GRUB ... etc" for over an hour. There were _no_ error messages. I was able to reboot using the rescue CD, and did full fsck's of all drives. Luckily I have another working system here with a burner and I created a boot CD so that I can get the machine to boot. After I got the machine to boot using a boot cd, I did a grub-install, but the results are different - I get Error 17 (which is cannot mount selected partition). This tells me that the wrong drive is being found by grub - this is a server with 5 large drives on it). But beyond that I am stumped. I've been RTFM'ing, but so far I haven't found any way to get grub to find the right drive in the boot process - or to tell me WHICH drive it actually is finding. (And I checked my grub.conf against a backup copy. Except for adding the new kernel, they are identical.) Removing the new kernel did not help (nor did re-installing it). Any suggestions would be welcome - not having grub working is inconvenient at best. -- william w. austin waustin@xxxxxxxxxxxxx "life is just another phase i'm going through. this time, anyway ..."
