I've installed Ubuntu, but when it is loading it gives following error:

mount:can't read proc/mounts. Can't fount such file or directory

However, OS continues loading but when I try to enter system using my login/password, which I entered during installation, it fails to login.

Does someone know what is problem here? I've tried reinstall ubuntu several times, but problem still occurs.

Medium from I installed: Windows 7. Installed Ubuntu with wubi, where I chose separate disk G(NTFS file format), set installation size: 18GB, chose Ubuntu in dropdownlist, language English(GB) and set username and password.

have you try to format the / partition of the disk G in EXT? – feligiotti Apr 22 '13 at 12:20

This is a caused by running an out of date wubi.exe from 12.04 or 12.04.1 (refer to bug Wubi 12.04 installs development release). Because the Wubi.exe is out of date it tries to download the development release wubi disk image. These are no longer created, but there is still a broken one from the 13.04 development release sitting out there, so it gets downloaded.

You need to get the latest Wubi for 12.04.2 from here: http://releases.ubuntu.com/12.04/wubi.exe

Or the 12.10 Wubi from here: http://releases.ubuntu.com/12.10/wubi.exe

There is also a 13.04 Wubi here: http://releases.ubuntu.com/13.04/wubi.exe

Any of these will work.

Go to Wubi installation folder

C:\ubuntu\install

open file

wubildr-disk.cfg

The content is:

loopback loop0 /ubuntu/disks/root.disk
set root=(loop0)
search --set=diskroot -f -n /ubuntu/disks/root.disk
probe --set=diskuuid -u $diskroot
linux /vmlinuz root=UUID=$diskuuid loop=/ubuntu/disks/root.disk preseed/file=/ubuntu/install/preseed.cfg wubi-diskimage ro quiet splash
initrd /initrd.img
boot

Change it to this:

loopback loop0 /ubuntu/disks/root.disk
set root=(loop0)
search --set=diskroot -f -n /ubuntu/disks/root.disk
probe --set=diskuuid -u $diskroot
linux /vmlinuz root=UUID=$diskuuid loop=/ubuntu/disks/root.disk preseed/file=/ubuntu/install/preseed.cfg wubi-diskimage ro quiet splash **single**
initrd /initrd.img
boot

That single word should be in same line and that is the only change

Then reboot your computer, and choose Ubuntu and it will boot into single user root mode

Create and user with command

adduser steve

and then add the user in sudo group

usermod -G sudo steve

Then type reboot

Go to windows and restore that wubildr-disk.cfg file to original version without the word single

reboot into Ubuntu and you will have steve user available to login from the login prompt.
