 Posted: Mon Jul 22, 2024 10:19 am Post subject: GRUB Rescue Mode Error During PXE Boot of a Prebuilt Gentoo |
 |
|
I've successfully set up a PXE boot environment for a diskless LiveCD. Now, I'm trying to PXE boot a prebuilt Gentoo system from another Gentoo system. I've configured both DHCP and TFTP servers:
The DHCP server assigns IP addresses to devices on the network and directs them to the TFTP server for boot files.
| Code: |
subnet 192.168.xx.x netmask 255.255.252.0 {
range 192.168.xx.190 192.168.xx.200;
option routers 192.168.xx.1;
option broadcast-address 192.168.xx.xx;
option domain-name-servers 192.168.xx.x;
next-server 192.168.xx.xxx; # IP address of your TFTP server
filename "grubx64.efi";
#filename "boot/grub/x86_64-efi/grub.efi"; # Boot file provided by TFTP server
}
|
The TFTP server serves the necessary boot files to clients. These files, including the GRUB configuration files, are placed in the TFTP directory.
| Code: | cat /etc/init.d/in.tftpd
INTFTPD_PATH="/tftpboot/"
INTFTPD_OPTS="-R 4096:32767 --secure --create -vvv ${INTFTPD_PATH}"
|
cat grub.cfg
| Code: |
set timeout=5
set default=0
menuentry "Gentoo Installation" {
linux /gentoo/vmlinuz-6.6.38-gentoo-x86_64 root=/dev/ram0 init=/linuxrc dokeymap looptype=squashfs loop=/gentoo/image.squashfs cdroot
initrd /gentoo/initramfs-6.6.38-gentoo-x86_64.img
|
However, when attempting to boot another VM on the same network using PXE, the boot process enters GRUB rescue mode with the error message: "grub rescue> gt3 not found."
Here is my file structure:
| Code: | ls -l
total 4972960
drwxr-xr-x 3 root root 4096 Jul 19 17:17 boot
drwxr-xr-x 2 root root 4096 Jul 19 17:28 gentoo

Can anyone help me with this issue? would appreciate guidance on where I might be going off track. |
