I tried leaving amessage on the Parted Magic forum, but I got no response.

What I want to do is change the default boot menu from VGA=791 to VGA=773 and SLEEP=10 to SLEEP=0

I've tried to change every single cfg file and either it fails to boot or I get, no file found error 15.

Using ImgBurn for Windows and ISO master for Linux.

changed /menu.lst, /grub4dos.lst, /boot/isolinux/isolinux.cfg, /boot/syslinux/suslinux.cfg.

No matter what is changed, it either fails to boot or constant rebooting. I see the correct info, if I do 'e' on the grub4dos bootup menu.

SOLVED by rebuilding the iso using mkisofs. Previous versions all I had to do was edit one of the "cfg" files.
