I installed Slackware 10.1 and when I rebooted(from floppy) after setup it gave me this error message "Kernel Panic :vfs: unable to mount rootfs on 03:42" I think this may have something to do with that I used reiserfs, but I reinstalled yesterday and it worked, in fact it worked better than any linux distro I've tried. I couldn't get the networking card working yet but it was great. I tried to boot into it again today and it was back to the same "kernel Panic" error! I re-booted with the startup disk instead of the floppy and looked in "cfdisk /dev/hdb" and the all three partitions(first was a swap, then primary reiserfs, then extra rieserfs) were gone! It was listed by cfdisk as free space! What happened!? Did the entire installation evaporate?!
On second thought, could Bootit NG be resetting it as free space? I alway keep it around when partitioning since I can't kill windows untill I can get to the internet on linux. I put it there last because when I installed slack over ubuntu, grub died and I couldn't boot windows for hepl and Bootit NG has always saved me when that happened. In other words, I use Bootit NG to boot windows XP when XP or grub wont boot on it's own.
