Error 13 when grub starts: solving the problem of invalid or unsupported executable

I’m using BT3 these days, and as for the USE of IT, we all know that I used GRUb4DOS as my desktop computer to launch recently. In recent days, I want to use my laptop to run BT3, but according to the general setting, GRUB shows Error 13: Invalid or unsupported Invalid on startup.
Looking around, it’s almost certain that the vmlinuz and BT3 cores don’t match, but it’s not clear why the same Settings worked on desktop computers.
The solution is as follows
After recompiling the kernel, restarting the system resulted in a GRUB boot error
Grub Error 13: Invalid or unsupported Invalid format
Error clause xp and FC co-existed when kernel/vmlinuzz-2.6.15 ro root= /dev/volgroup00 /LogVol00 RHGB quiet
installation. Restart the system again, enter xp, and search for the solution to Error 13.
use the rescue disk to enter the fc, check the Settings in /etc/grub.conf file, and check the filename in the Settings. It matches the file on your hard drive.
USES Google again to view the explanation of the vmlinuz file. On, see
. Vmlinuz is the executable Linux kernel. It is located at /boot/vmlinuz and has two ways to build it. First, the kernel is created by “make zImage” when compiling, and then by:
“Cp/usr/SRC/Linux – 2.4/arch/i386/Linux/boot/zImage/boot/called”. ZImage is suitable for small kernels and exists for backward compatibility. The second is the kernel compile time through the command make bzImage created, then through: “cp/usr/SRC/Linux – 2.4/arch/i386/Linux/boot/bzImage/boot/called”.
Because vmlinuz is before compiling the kernel, the original system does not match the system after compiling the kernel, so it cannot be started
. Restart to enter grub, press e to modify, change vmlinuz-version to bzImage, press b to start Linux
to enter Linux. Go to/boot/ and delete the old vmlinuz, then rename the bzImage to vmlinuz-version
and everything will work fine.
