Lenovo 550 notebook
dual boot LM8 x64 and Windows 7 x64 with mint being default.

I've had this working fine without problems for a long time and today, I was working on windows and rebooted to go back to mint.
After grub, I see the LM logo and then everything is blank. I don't hear the hard drive doing anything either. Just sits there and does nothing. Only way to get out is to hard shutdown by holding the power button.

Worked fine this morning as well. Last time I saw it working I had let the laptop go into the login screen on LM when I needed to go into windows. I clicked on the little icon on the bottom right and selected reboot.

This is not the first time after install. This has never happened before.

Need help

Are you able to choose Recovery mode at the grub screen ? And if so, are you able to login with your sudo password? you can then try startx , to see if we can get you to the GUI . . . or it may at least show you some more info on troubleshooting the problem.

oh yea, you haven't made any hardware changes, or added something lately, have you ?

It takes me to a prompt when I go through the recovery mode. However, it never asks for a password.

I haven't made any hardware changes to the machine. Earlier today I turned on the machine at a friends house because I wanted to copy a file for him from my windows install. I forgot to select windows at grub and it went to the LM login at which point I just used the button on the bottom right corner to reboot. That was the last time I saw the login prompt.

Now, at grub the count down is missing, so it will just sit on grub until I press enter.

Also, couple of weeks ago, my splash screen suddenly turned into "ubuntu" instead of linux mint like it has been for so long. I didn't pay much attention because the functionality wasn't affected by it. Other than messing with the flash installs through package manager, I haven't really done much else but daily use.

ps. I keep having to come back to windows install to check on this thread because I don't have another computer at the house and posting with the iphone keyboard is quite painful.

ok borrowed my cousins laptop...

I'll start typing parts that seems to give errors at the end of recovery mode;

Begin: Waiting for root file system... ...
Done.
Gave up waiting for root device. Common Problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)

It's looking for a hard drive with that uuid number, and cannot find it, thus dropping you to the prompt .

Suggestion, at the prompt try: sudo update-grub

here's a pic of grub

btw, I really appreciate you taking the time to help me with this. I have a bunch of files on that install I need to get to. I didn't have time to make backups since the last time and there had been many updates to those files and many more I really need to get to.

same thing, "not found"

edit: crashing for the night. Been sick and meds making me dizzy. I'll check back here in the morning. Hopefully I can get this working tomorrow. Thanks again.

I don't have a live disk at the moment. I'm already downloading one (LM9 though). I have an iso for LM8 but its in the partition that's not working right now lol.

Post by **richyrich** » Fri Sep 24, 2010 3:16 am

I think grub is a different version, so don't try to copy anything over from the disk . . but you can use it to check if you can at least see/mount the partition, and view your data.

sorry I don't have anything other to suggest, let us know how it goes . . . richy

Check the filesystem via liveCD`s command line.

sudo fdisk -l

....you see the media. An example: Check partition /dev/sda5

sudo fsck -fyc /dev/sda5

When linux partitions are checked, reboot your PC

If that does not help, do this operation

yeah, I decided to download LM8 x64 the same one I had just in case

Tried fsck'ing /dev/sda5 and nothing changed. I'm about to check out your other post.

here's the fdisk

mint@mint ~ $ sudo fdisk -l

Trying to follow the instructions on your other post

The another way is to chroot via liveCD

An example via liveCD's terminal

sudo fdisk -l

....check the media. If Mint resisdes on sda5

sudo mount /dev/sda5 /mnt

sudo mount --bind /dev /mnt/dev

sudo mount --bind /proc /mnt/proc

sudo mount --bind /sys /mnt/sys

sudo chroot /mnt

nano /etc/default/grub

..........ctrl o = write , ctrl x = quit

update-grub

Ctrl D

sudo umount /mnt/dev

sudo umount /mnt/sys

sudo umount /mnt/proc

sudo umount /mnt

exit

having trouble mounting sda5

mint@mint ~ $ sudo mount -t ext3 /dev/sda5 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/sda5,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

from syslog

EXT3-fs: sda5: couldn't mount because of unsupported optional features (240)

tried without -t ext3 and...

mint@mint ~ $ sudo mount /dev/sda5 /mnt
mount: you must specify the filesystem type

tried ext2 as well with the same results.

anubis00x · Post by **anubis00x** » Fri Sep 24, 2010 7:25 pm

also just noticed I'm missing the uuid for sda5

mint@mint / $ ls -l /dev/disk/by-uuid/
total 0
lrwxrwxrwx 1 root root 10 2010-09-24 21:45 08DCDE01DCDDE948 -> ../../sda2
lrwxrwxrwx 1 root root 10 2010-09-24 21:45 1070E34670E33160 -> ../../sda3
lrwxrwxrwx 1 root root 10 2010-09-24 21:45 2ca7b163-e4e3-49a6-b245-5752fc0e32f2 -> ../../sda6
lrwxrwxrwx 1 root root 10 2010-09-24 21:45 3E56A8BA56A87475 -> ../../sda1

anubis00x · Post by **anubis00x** » Fri Sep 24, 2010 7:43 pm

tried again after another fsck

mint / # mount -o ro -f -t ext3 /dev/sda5 /mnt
mint / # cd /mnt/
mint mnt # ls -la
total 0
drwxr-xr-x 2 root root 3 2009-10-20 01:18 .
drwxr-xr-x 32 root root 280 2010-09-24 21:45 ..

nothing....

anubis00x · Post by **anubis00x** » Fri Sep 24, 2010 7:53 pm

UPDATE:

this worked,

mint / # mount -o ro -t ext4 /dev/sda5 /mnt
mint / # cd mnt/
mint mnt # ls
bin cdrom etc initrd.img lib32 lost+found mnt proc sbin srv tmp var
boot dev home lib lib64 media opt root selinux sys usr vmlinuz

Edit: Just to clarify, the initial issue isn't resolved. Since I'm able to access my important files, they are all being copied over to the windows partition at the moment.
Once that is completed still need to figure out how the uuid went missing for /dev/sda5 and to try resolve this.
If it's not possible, I'm already downloading a copy of mint 9 which will be a complete wipe and reinstall of the partition.

anubis00x · Post by **anubis00x** » Sat Sep 25, 2010 3:15 am

Crude fix and resolution (at least for now)

Basically the uuid for sda5 was missing, replaced it in fstab with /dev/sda5

Original entry in fstab

# / was on /dev/sda5 during installation
UUID=de48d301-418e-41a8-9cfe-3cf8ebd58b90 / ext4 errors=remount-ro 0 1

Current entry

# / was on /dev/sda5 during installation
/dev/sda5 / ext4 errors=remount-ro 0 1

I will more than likely install LM9 on this partition soon either way, but for now I'm in and have backups of all the files I need

Thanks for the help guys!
