(wubi install in windows 7) ubuntu froz... i hard booted and now at start up if i select ubuntu i get : Try (hd0,0) : NTFS5; No wubildr Try (hd0,1) : NTFS5: error: "prefix" is not set. then I am dumped into grub prompt. I did chkdsk /r from windows didnt find anything but an error in an old video file. and windows has done a clean shut down. same errors occur In windows both my root.disk and root.swap files are in the ubuntu\disks\ dir. one thing i notice is that Ubuntu\disks\boot\grub\ is completely empty including hidd (Hardware)
