Anyway, I upgraded to Hardy over the weekend, deciding to tidy up my partitions to increase my linux install space to allow for a VirtualBox. I deleted my original partitions, using the Live CD & gparted, then created 2 new ones for / and /home. Installed Hardy and that boots fine. When I try to boot to XP though I get Error 27: Unrecognised command. Have followed some threads which suggest refreshing grub, following: Code: find /boot/grub/stage1 reports hd0,6 Code: root (hd0,6) Code: setup(hd0) But whenever I get to setup(hd0) I get another error 27! Any help to get the beast of XP back to life would be appreciated....

I've never used Grub before but did some digging online. Looks like I have to run the kernel command before I can boot the system. However, the kernel command is not running. As I installed the OS I checked the box that said something like "Install boot loader on /dev/sda". The following is http://unix.stackexchange.com/questions/31226/trouble-booting-server-from-grub-prompt what I've done: grub> find /vmlinuz-2.6.32-220.el6.x86_64 (hd1,0) grub> root (hd1,0) grub> kernel /vmlinuz-2.6.32-220.el6.x86_64 root=/dev/sda1 Error 27: Unrecognized command I've tried it with and without the root=/dev/sda1, just /dev/sda, also tried a ro inserted in the middle but nothing works. I've read the docs but at a bit of a loss.

I also recommend entering your commands from the edit screen, and then booting with CTRL-X here is an example, I would assume you will have to change things to fit your installation. root (hd1,0) kernel /vmlinuz-2.6.18-92.1.22.el5 ro root=LABEL=/ initrd /initrd-2.6.18-92.1.22.el5.
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 http://www.uruk.org/orig-grub/errors.html error message will occur if the Stage 2 or Stage 1.5 is being read from a hard disk, and the attempt to determine the size 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 from a floppy disk, and the attempt to determine the size and geometry of the floppy disk fails. It's error 27 listed as a different error since the probe sequence is different than for hard disks. "Read Error" This error message 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. error 27 unrecognized 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 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 comman
