Only Memtest after deleting old kernels

[qwyrp]

I deleted some old kernels but something went wrong. My server now only starts up in Memtest mode. I've tried it with Boot-repair (Recommend options) and after hours (> 4) of purging I stopped it. I managed to get some info from Boot-repair and they suggest to get help from forums. Here's is the log-file http://pastebin.ubuntu.com/14137017/plain/ and hopefully somebody can save me.
- ubuntu server 14.04 - 64b

What was the method (or exact sequence of commands) you were using to delete old kernels?
Was this normal maintenance, or were you responding to a warning or error?

[qwyrp]

Something like uname -r and sudo apt-get autoremove linux-image-* where * was the old kernels (at least this was supposed to be old).
There was no warning or error and pure maintenance

qwyrp; Hello;

Ouch ! Is the server still running ? You have not re-booted, have you.

If still running, maybe we can get a fix:
For starters :
Post back - Between code tags - these terminal command outputs:


uname -r
dpkg-l | grep linux-
ls -al /usr/src/
ls -al /lib/modules/
ls -al /vmlinuz*
ls -al /initrd.img*
ls -al /boot
df -h
df -i

To give us an idea of what we are working with and what we are working toward.

This may get real




interesting

The safe command is sudo apt-get autoremove without mentioning kernels.

I've already rebooted and that why I'm knowing I'm in trouble

You should be able to install a kernel from a chroot environment: see

http://askubuntu.com/questions/28099/how-to-restore-a-system-after-accidentally-removing-all-kernels

for example

Okay this is probably not working because I'm also using LVM (sorry forget to mention this:oops:

[Skaperen]

it's obvious to me that all kernels got deleted as all that is remaining is memtest. rescue disk time. do you still have the CD/media that was originally used to do the install? if so, see if it will boot (choose it in BIOS) and let us know.

[qwyrp]

I don't have the original CD/media but I've checked it with Ubuntu LiveCD and it's bootable

Do you know what the issue is with LVM exactly? Pretty sure I've done it on an LVM based system (in fact I'm pretty sure that's the ONLY time I've done it) - although my memory may be failing me.

Shouldn't it just be a matter of making sure the lvm2 package is installed on the live system, then identifying the correct /dev/mapper/vgwhatever--lvwhatever for the / filesystem (using blkid / parted / fdisk)?
