F14 preupgrade fails reboot - "unknown command" in grub


Hello,

While upgrading from Fedora 13 x86_64 to Fedora 14 x86_64, I got warning dialog which said boot partition didn't have sufficient space to download the image. I say warning because it informed that the install could download it later, but if I was on WIFI, best stop now.

I was on a wired connection, so I selected continue. After downloading all the packages, after reboot, I have 3 Fedora kernels and an Upgrade F14 kernel in my grub menu.lst, but none of them work.

I've looked at the commands and they look reasonable. Unfortunately, I don't have a DVD on this machine (currently trying to make a USB Live-CD)... and I don't see a repair option to drop into a shell - not sure if I can do an ls of the boot drive - I suspect files may have been removed.

Any suggestions? Any bugs on this? I tried searching but didn't find this issue listed.

Thanks in advance for any help.
John

sounds like you have run out of space on /boot. Is there any other distro installed? Have you a floppy? If so, you can boot from

http://www.toms.net/rb

and you can build Tom's linux under linux or under windows. Can you put the harddrive in another box running linux? If so run df -h and see what's going on.

Thanks for the advice and help. I did try both Windows and Linux versions of LiveUSB-Creator and they failed to create a bootable 2GB flash drive - tried Fat, Fat32, Ext4, NTFS, and either syslinux -d failed or the format type was unrecognized.

Since it looks like the IDE is out on my motherboard, I'll wait and spring for a SATA DVD drive and try again with the F14 DVD I burned.

If the /boot partition runs out of space, it would be good not to hose the ability to revert.

The disk uses minix, IIRC, with some tweak to the floppy measurements to be 1.82 Megs. It's been a long time.

On a usb key, way to go would be make a 3mb(+) partition and a filesystem for the El-To0rito image which is 2.88Mb. Alternatively you may try Kevux (http://kevux.org) which I think goes straight on to usb key. Ignore miost of the (broken) links - you can download kevux there.
