File not found"

你用info grub就能看到所有grub的出錯碼


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 *Note 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 *Note

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 ma
