View Full Version : [SOLVED] Hmmm - computer repair shop messed up my linux installation

Dear all,

Thanks for reading. I've just had to get my PC repaired and, although I warned the repair shop that the system was a linux machine (I have GRUB and dual boot Vista when I have to use Windows), they attempted to 'repair the disks' as part of the service and messed up the linux installation (Windows, of course, still runs fine). When I collected the PC, they said, 'Sorry, we don't really do linux here'. I was terrified that they had managed to wipe the whole partition, and was ready to get angry with them, but fortunately, that's not the case.

The problem is that, now when I try to boot into linux, it initially hangs, then goes to a purple splash screen saying that /tmp is missing - do I want to repair etc.. Repairing does no good and I'm not skilled enough to fix this manually. I've managed to boot using a 10.04 live cd, access the linux partition and I can confirm that the /tmp directory is present (phew)

I guess my question is, what do you think is missing so that I can rescue the old installation, or, perhaps, what can I do to find out what is missing...

As I said, I've managed to boot with a live cd and am in the process of backing up important data before I proceed (I know, I should have done this before the computer breaks down :-))



I ran boot info script from the live cd so that the experts can have a look, if they like:

Thanks for reading!

## lines between the AUTOMAGIC KERNELS LIST markers will be modified

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=fe1d92eb-9451-49eb-aab6-a0d249dfae27 ro

## default grub root device
## e.g. groot=(hd0,0)
# groot=fe1d92eb-9451-49eb-aab6-a0d249dfae27

## should update-grub create alternative automagic boot options
## e.g. alternative=true
## alternative=false
# alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false
# lockalternative=false

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash

## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# lockold=false

## Xen hypervisor options to use with the default Xen boot option
# xenhopt=

## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(recovery) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all

## specify if running in Xen domU or have grub detect automatically
## update-grub will ignore non-xen kernels when running in domU and vice versa
## e.g. indomU=detect
## indomU=true
## indomU=false
# indomU=detect

## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true

## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false

## should update-grub add savedefault to the default options
## can be true or false
# savedefault=false

Hi Guys,

Running fsck for a second time seemed to do the trick - it's all working fine again.

Thanks for reading.
