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
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.
I'm still unable to find the directory that contains the
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/
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/
