My system has WinXP installed and Fedora Core 3 also. Using grub to boot, I get Error 25 every time, no matter which of the grub menu choices I try to boot. I have four Linux kernals and one Windows OS as choices via grub. I have grub installed on a bootable CDROM, not in the MBR. I specified to put grub in the MBR when installindg core 3, but it appears to have ignored my request. If it indeed is there, it does nothing. Could be because it default boots to WinXp with a hiddenmenu (the default setup by intall). It doesn't recognize an k

• Page 1 of 1 Debian 5: Grub Error 25 [solved] by werdigo49 » 2009-02-19 21:53 I'm using D5 to post this, but had to load it through the Graphical Rescue option on DVD #1 (running as root, using "startx"). Trying debian grub single user mode a normal boot from /dev/hda1 gives "GRUB Loading Stage 1.5; GRUB loading, please wait...; ERROR debian grub change default kernel 25" I've run into this on my main system (Klikit, a Kubuntu-based distro) when Grub by default specified hd(1,0); after editing it to

Debian Grub Efi

hd(0,0) all was fine. My Debian 5 grub already shows hd(0,0). I tried editing it to hd(1,0) just on the off chance, and of course that didn't work... still an ERROR 25. Any suggestions? --werdigo49 Last edited by werdigo49 http://www.linuxquestions.org/questions/linux-software-2/grub-error-25-disk-read-error-275052/ on 2009-02-21 13:27, edited 1 time in total. werdigo49 Posts: 24Joined: 2009-02-19 01:29 Top by logan » 2009-02-19 22:06 (hd1,0) would be the first partition on the second drive, so maybe another device was seen as /dev/sda before the hard drive? I don't know if you tried changing /boot/grub/menu.lst, but when Debian updates a kernel or certain system configurations, it'll recreate initrd and run update-grub, which changes /boot/grub/menu.lst. If you updated one (the wrong) line and ran http://forums.debian.net/viewtopic.php?t=35946 some system updates, the root may have been reset. Make sure you change all instances of (hd1,0) to (hd0,0) or update the groot= line in /boot/grub/menu.lst and run update-grub: ## default grub root device## e.g. groot=(hd0,0)# groot=(hd1,0)should look like:## default grub root device## e.g. groot=(hd0,0)# groot=(hd0,0) If this doesn't work, can you paste the output of fdisk -l /dev/sda, what each partition is used for (/, /var, /boot, swap, etc), and the contents of /boot/grub/menu.lst? logan Posts: 269Joined: 2008-03-29 18:09 Top by werdigo49 » 2009-02-19 22:21 Thanks, Logan... yes, I should have been more specific: That editing was done in the grub menu.lst. I now have everything changed back to hd(0,0). The device map shows that (hd0) is /dev/hda, and (my secondary sata drive) (hd1) is /dev/sda. (I found another post (marked "solved") with a boot problem, in which Mase recommended the OP change his menu.lst items from hda3 to hda1... but mine are already hda1.) When I installed, I set up hda1 as /, hda3 as swap, and saved an old /home (from another distribution) as hda2. The / was formatted as reiserfs (the old /home is also). I can't get a terminal window using this graphical rescue setup --- it gives me a "error creating the child process" message. When I get out of this graphical rescue I'll see what I can find with fdisk. EDIT: Can't copy/

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 Stage 1.5 is being read from a hard disk, and the attempt to http://www.uruk.org/orig-grub/errors.html 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 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 debian grub 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 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 debian grub error 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 the system. 3 : "Disk read error" This error is returned if there is a disk read error when trying to probe or read data from a particular disk. 4 : "Disk write error" This error is returned if there is a disk write error when trying to write to a particular disk. This would generally only occur during an install of set active partition command. 5 : "Disk geometry error" This erro
