I multi-boot Windows XP and 5 Linux distros on a single hard drive. Some of the distros come and go but I keep at least two that are my daily use distros. My boot loader is grub1 located on a ext3 formatted distro. I have installed a distro that requests the partition be formatted ext4, which I did. I have been trying to edit my grub1 menu.lst so that I can chainload the ext4 distro get errors or it goes to the command line with the last word being Grub. My question is, can grub1 ext3 chainload a grub2 ext4 distro?
Here is a sample of my menu.lst
title MEPIS at sda7, newest kernel
kernel /boot/vmlinuz root=/dev/sda7 nomce quiet splash vga=789
title Microsoft Windows XP Home Edition at sda1
# for Mint Debian on sda5
title Mint Debian on sda5
# for Crunchbang on sda6
# for SuperOS on sda8
title SuperOS 10.10
#for Aptosid 2010
title Aptosid 2010
Mepis is the location of my menu.lst and is ext3 on sda7 and aptosid is the ext4 distro that I am trying to boot on sda9 and it uses grub2.
