grub.cfg file configuration help

niravshah · 07-17-2009, 07:42 PM

I have installed grub2 on a flash drive
though after installing I did not find grub.cfg file in the /boot/grub/
so i placed it from the my existing system but the problem is when i boot from this flash drive i get this error

unknown command 'boot' for all the menu item

I have added this entry to my
menuentry " Testing to boot ISO" {
loopback loop (hd0,0)/myiso.iso
linux (loop)/isolinux/vmlinuz boot=fll quiet vga=791 fromiso=/myiso.iso
initrd (loop)/isolinux/initrd.img
boot
}

anyidea what causing this error

hi

I have not succeeded with my efforts in this area atm but I can spot some minor errors

(hd0,0)

grub2 counts hds from zero.....ok
grub2 counts partitions from ONE

2) assuming its now (hd0,1)/myiso.iso...are you sure your iso is under /?

3) if you mount the cd normally....are you sure the filenames on the cd and pathway are
/isolinux/vmlinuz etc?

4) fromiso needs a full pathway is dev speak

/dev/sda1/pathway/myiso.iso

it could be vmlinuz-version x?
