error string and then halt. Pressing Ctrl-Alt-Del will reboot. The following is a comprehensive list of error messages for the Stage 1: "Hard Disk Error" This error message will occur if the Stage 2 or grub rescue no such device Stage 1.5 is being read from a hard disk, and the attempt to determine the size grub rescue disk and geometry of the hard disk fails. "Floppy Error" This error message will occur if the Stage 2 or Stage 1.5 is being read error no such partition from a floppy disk, and the attempt to determine the size and geometry of the floppy disk fails. It's listed as a different error since the probe sequence is different than for hard disks. "Read Error" This error message https://wiki.gentoo.org/wiki/GRUB_Error_Reference will occur if a disk read error happens while trying to read the Stage 2 or Stage 1.5. "Geom Error" This error message will occur if the location of the Stage 2 or Stage 1.5 is not in the area supported by reading the disk with the BIOS directly. This could occur because the BIOS translated geometry has been changed by the user or the disk is moved to another machine or controller after installation, or GRUB was http://www.uruk.org/orig-grub/errors.html not installed using itself (if it was, the Stage 2 version of this error would have been seen during that process and it would not have completed the install). Errors Reported by the Stage 1.5 The general way that the Stage 1.5 handles errors is to print an error number in the form "Error: " and then halt. Pressing Ctrl-Alt-Del will reboot. The error numbers correspond to the Errors Reported by the Stage 2 in the listed sequence. Errors Reported by the Stage 2 The general way that the Stage 2 handles errors is to abort the operation in question, print an error string, then (if possible) either continue based on the fact that an error occurred or wait for the user to deal with the error. The following is a comprehensive list of error messages for the Stage 2 (error numbers for the Stage 1.5 are listed before the colon in each description): 1 : "Selected item won't fit into memory" This error is returned if a kernel, module, or raw file load command is either trying to load it's data such that it won't fit into memory or it is simply too big. 2 : "Selected disk doesn't exist" This error is returned if the device part of a device- or full filename refers to a disk or BIOS device that is not present or not recognized by the BIOS in

I believe I installed Ubuntu over Windows on my Acer netbook. I then tried to install Linux grub rescue no Mint, but it wouldn't start installing. I turned the netbook off and back on. Now I get the error. I have read a lot of other questions like this, but in my case I cannot boot a CD.
