Quad Boot Problems: Vista, Centos, Fedora 6, Suse 10.3

[fuzzielitlpanda]

This is the order I have installed these OS:

1. Vista
2. CentOS
3. Fedora 6
4. Suse 10.3

Everything was working fine before I tried to install Suse. After installing Suse, I wasn't able to boot into any of the other OS. I'm sure there was a problem with the way I configured the bootloader, but I have no idea what I did wrong nor what to do to fix it.

After modifying the bootloader in centos, i am now able to boot centos and vista, but fedora and suse are a no go. here is the error i am getting when i try to boot either os:

error 13: invalid or unsupported executable format

what do you guys think?

here is my boot menu:

I installed Fedora on hdc6 and Suse on hdc8. What changes should i make?

Hi and Welcome !

Have you installed Fedora and SuSe's GRUB in the boot sectors of their own root partitions ( or /boot, if you have created for those )?
Chainloading will not work if you havn't installed GRUB in boot sector.


Mount Fedora and SuSe's root partitions and copy 'title, root, kernel and initrd' lines from /boot/grub/grub.conf ( Fedora ) and menu.lst (SuSe) files. Paste those lines in CentOS's grub.conf file.
