Booting from local disk
GRUB loading stage 1.5
GRUB loading, please wait...
error 25
然后停止响应。

ubuntu已经运行很长一段时间了,一直没问题,不明白为什么会出现这个问题,怎么办?

请高手指点!我的linux盘里还有很多重要东西。

从 gnu grub manual 0.97 摘抄的错误号含义:


1 : Filename must be either an absolute filename or blocklist
This error is returned if a file name is requested which doesn't fit the syntax/rules listed in the Filesystem.
2 : Bad file or directory type
This error is returned if a file requested is not a regular file, but something like a symbolic link, directory, or FIFO.
3 : Bad or corrupt data while decompressing file
This error is returned if the run-length decompression code gets an internal error. This is usually from a corrupt file.
4 : Bad or incompatible header in compressed file
This error is returned if the file header for a supposedly compressed file is bad.
5 : Partition table invalid or corrupt
This error is returned if the sanity checks on the integrity of the partition table fail. This is a bad sign.
6 : Mismatched or corrupt version of stage1/stage2
This error is returned if the install command points to incompatible or corrupt versions of the stage1 or stage2. It can't detect corruption in general, but this is a sanity check on the version numbers, which should be correct.
7 : Loading below 1MB is not supported
This error is returned if the lowest address in a kernel is below the 1MB boundary. The Linux zImage format is a special case and can be handled since it has a fixed loading address and maximum size.
8 : Kernel must be loaded before booting
This error is returned if GRUB is told to execute the boot sequence without having a kernel to start.
9 : Unknown boot failure
This error is returned if the boot attempt did not succeed for reasons which are unknown.
10 : Unsupported Multiboot features requested
This error is returned when the Multiboot features word in the Multiboot header requires a feature that is not recognized. The point of this is that the kernel requires special handling which GRUB is probably unable to provide.
11 : Unrecognized device string
This error is returned if a device string was expected, and the string encountered didn't fit the syntax/rules listed in the Filesystem.
12 : Invalid device requested
This error is returned if a device string is recognizable but does not fall under the other device errors.
13 : Invalid or unsupported executable format
This error is returned if the kernel image being loaded is not recognized as Multiboot or one of the supported native formats (Linux zImage or bzImage, FreeBSD, or NetBSD).
14 : Filesystem compatibility error, cannot read whole file
Some of the filesystem reading code in GRUB has limits on the length of the files it can read. This error is returned when the user runs into such a limit.
15 : File not found
This error is returned if the specified file name cannot be found, but everything else (like the disk/partition info) is OK.
16 : Inconsistent filesystem structure
This error is returned by the filesystem code to denote an internal error caused by the sanity checks of the filesystem structure on disk not matching what it expects. This is usually caused by a corrupt filesystem or bugs in the code handling it in GRUB.
17 : Cannot mount selected partition
This error is returned if the partition requested exists, but the filesystem type cannot be recognized by GRUB.
18 : Selected cylinder exceeds maximum supported by BIOS
This error is returned when a read is attempted at a linear block address beyond the end of the BIOS translated area. This generally happens if your disk is larger than the BIOS can handle (512MB for (E)IDE disks on older machines or larger than 8GB in general).
19 : Linux kernel must be loaded before initrd
This error is returned if the initrd command is used before loading a Linux kernel.
20 : Multiboot kernel must be loaded before modules
This error is returned if the module load command is used before loading a Multiboot kernel. It only makes sense in this case anyway, as GRUB has no idea how to communicate the presence of such modules to a non-Multiboot-aware kernel.
21 : Selected disk does not exist
This error is returned if the device part of a device- or full file name refers to a disk or BIOS device that is not present or not recognized by the BIOS in the system.
22 : No such partition
This error is returned if a partition is requested in the device part of a device- or full file name which isn't on the selected disk.
23 : Error while parsing number
This error is returned if GRUB was expecting to read a number and encountered bad data.
24 : Attempt to access block outside partition
This error is returned if a linear block address is outside of the disk partition. This generally happens because of a corrupt filesystem on the disk or a bug in the code handling it in GRUB (it's a great debugging tool).
25 : 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.
26 : Too many symbolic links
This error is returned if the link count is beyond the maximum (currently 5), possibly the symbolic links are looped.
27 : Unrecognized command
This error is returned if an unrecognized command is entered on the command-line or in a boot sequence section of a configuration file and that entry is selected.
28 : Selected item cannot fit into memory
This error is returned if a kernel, module, or raw file load command is either trying to load its data such that it won't fit into memory or it is simply too big.
29 : 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.
30 : Invalid argument
This error is returned if an argument specified to a command is invalid.
31 : File is not sector aligned
This error may occur only when you access a ReiserFS partition by block-lists (e.g. the command install). In this case, you should mount the partition with the `-o notail' option.
32 : Must be authenticated
This error is returned if you try to run a locked entry. You should enter a correct password before running such an entry.
33 : Serial device not configured
This error is returned if you try to change your terminal to a serial one before initializing any serial device.
34 : No spare sectors on the disk
This error is returned if a disk doesn't have enough spare space. This happens when you try to embed Stage 1.5 into the unused sectors after the MBR, but the first partition starts right after the MBR or they are used by EZ-BIOS.

错误25:磁盘读错误
如果你什么也没做,突然有一天出来 error 25,这大概是磁盘失效的前兆。
用livecd进去看看,如果你的资料还在,我建议你马上备份。

只是装完启动的时候就出现这个怎么办?要用原安装盘去启动么?那岂不是还是光盘启动,怎么从硬盘启动呢?

汇报一下:
今天又搞了一个9.04装上还是报这个问题,机器是联想M8000T的,所以怀疑是不是硬件的原因,问了800,无果,上网查了一个成功案例就是进 bios将SATA AHCI 这个模式设置成Enabled,保存后,呀~~起来了,自此困扰我多年的GRUB error 25问题彻底解决了 :em11
