Note: Before you mark it as duplicate, please read the question fully.

I've been using Ubuntu 12.04 normally, but today when I turned my laptop on, and selected Ubuntu out of two options: Windows and Ubuntu, the following screen appeared:

I searched this a lot on here, but couldn't find a working solution.

One solution suggested me that I should do first ls in different partitions and see where the file vmliuz or initrd resides. But I found no where these files.

I also played with the brightness of my laptop, which may be a cause of this stuck screen.

Edit 1:

I'm still unable to find the directory that contains the initrd.img file.

grub> ls 

(memdisk) (hd0) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1)

grub> set pager=1

grub> ls (memdisk)/

wubuilder.cfg

grub> ls (hd0)/

error: unknown filesystem.

grub> ls (hd0,3)/

$AttrDef $BadClus $Bitmap $Boot $Extend/ $LogFile $MFT $MFTMirr $RECYCLE.BIN/ $Secure $UpCase $Volume ./ Code School/ Downloads/ Movies/ System Volume Information/ ubuntu/ wubuilder

grub> ls (hd0, 2)/

Programming Files (x86)/ Users/ $AttrDef $BadClus $Bitmap $Boot $Extend/ $LogFile $MFT $MFTMirr $RECYCLE.BIN/ $Secure $UpCase $Volume ./ Documents and Settings/ hiberfil.sys Intel/ MSOCache/ pagefile.sys PerfLogs/ Program Files/ ProgramDAta/ Recovery/ Setup/ swsetup/ System Volume Information/ Windows/ wubildr wubildr.mbr

grub> ls (hd0, 1)/

$AttrDef $BadClus $Bitmap $Boot $Extend/ $LogFile $MFT $MFTMirr $RECYCLE.BIN/ $Secure $UpCase $Volume ./ Boot/ bootmgr BOOTSECT.BAK System Volume Information/

Edit 2:

Also, please note that I've installed Ubuntu 12.04 and Windows 7. And my Ubuntu resides at the following location; I checked it by booting up Windows OS:

grub ls (hd0,3)/ubuntu/

install/ uninstall-wubi.exe winboot/

If you have installed without Wubi.exe:

At the grub prompt try these commands:

set pager=1

ls

Now, suppose the output of ls is: (hd0) (hd0,msdos2) (hd0,msdos1), in order to find the linux root filesystem run:

ls (hd0,1)/
which should give you all the files/folders in / such as bin/ boot/ cdrom/ dev/ etc/ home/ lib/ etc.

Once this is done continue with:

set root=(hd0,1)

linux /boot/vmlinuz-3.13.0-29-generic root=/dev/sda1

initrd /boot/initrd.img-3.13.0-29-generic

boot

Of course replace vmlinuz-3.13.0-29-generic and initrd.img-3.13.0-29-generic with what you find in your /boot

/dev/sda1 is the location of the root system. You may have to change it if /dev/sda1 did not work.

If you have installed using Wubi.exe:

If you have installed Ubuntu using Wubi, perform following steps as given in the WubiGuide:

boot into Windows, run chkdsk /r from Windows on the same drive where you installed Ubuntu, shutdown cleanly and then try to boot into Ubuntu again.

if still not good, check that you have a C:ubuntudisks oot.disk file. If this file is missing, boot on Windows, open the Windows Explorer, set it to be able to see hidden folders, then look for a hidden folder called C: ound.000 or dir0000.chk . Move the files from found.000 to their original location inside the ubuntudisks directory. You may have to rename it into root.disk.
