debian upgrade not booting

Post by Master of Reality » Thu Jan 03, 2008 4:02 pm

So i did a dist-upgrade on debian testing on my laptop to upgrade everything. Now none of the kernels boot, GRUB gives me an error saying
Error 17: Cannot mount selected partition
I dont know my partition scheme, so i decided to try to boot a Kubuntu live DVD i had lying around and check it out.
While booting it gives me this error (and similar ones several times)
Buffer i/0 error on device sr0, logical block 279335
SQUASHFS error: unable to read fragment cache block
SQUASHFS error: unable to read page
I think to myself, "this looks like a job for system rescue CD" and it loads to the point saying
ISOLINUX version
and freezes there.

I have windows installed on this as well and it boots. I really need the data on my linux partition, but if the filesystem is messed up and i install the ext2 windows driver even worse things could happen to my data.

Any idea on the problem, i'm about to look for a utility to check for bad blocks that i will be able to use (i used scandisk, but dont put any faith in it anyway).

I'm thinking maybe its a filesystem problem, but then i dont know why my bootable DVD does not work.

does the live dvd try to mount your linux partition at the point it is freezing? that's just an idle thought, and is probably not the case or i think you'd have mentioned it.

If it was the case though, i'd try using a live-bootable disk that doesn't automatically mount your partitions.

not much help, sorry.

well err.. for some reason i decided to download an image of the system rescue cd that was a year old and boot that. And it worked, and i found out my partition scheme and that debian had done its automagic kernel entries to menu.lst to change all the entries to a root partition that doesnt exist.

So i guess the kubuntu dvd has an unrelated device problem, and the newest system rescue cd (based on gentoo) has some other problem.

Coincidences?

Did I hear that right? The latest Debian rescue disk is based on Gentoo?

no, it is a live CD distro called System Rescue CD (www.sysresccd.org)
