Lost boot capability after yum update
First thing, I'm completely new to Linux. I did a dual boot system install which both XP and Fedora resided happily on the same drive. After a day or so of figuring this and that out, for example fixing the baseurl= issues with yum or the add/remove programs feature, I was finally able to use yum to update. I did a full update, which took 45 minutes, and rebooted the system. I had Fedora 2.6.15 and updated to 2.6.18 FC5. Grub loaded fine, and once it loaded the X system, it would show the progress bar loading and before the login screen, it would error and put me to the shell prompt. I had one option to go to maintenance, but I have no idea how to do anything in there. I'm not sure how to pull any logs or files out to see if anything was there that pertained to what you guys have told others to do here in your forums. I am at a complete loss to what to do. Oh yeah, it happens as well when trying to boot to the old kernel. Any help would be appreciated. I can, if needed, try it again and handwrite everything down if I need to. Windows still boots, so I have access to the net.
Thank you very much in advance.
