grub

Error 18: Selected cylinder exceeds maximum supported by BIOS
-> the bios is too old and the kernel is byond the 8 Gbyte limit

Install the grub from rescue disc:
mount /dev/sda? /mnt/sysimage
mount --bind /dev /mnt/sysimage/dev
chroot /mnt/sysimage
grub-install /dev/sda


IF the partitions are as follows:
/dev/sda1 windows
/dev/sda2 extended
/dev/sda5 swap
/dev/sda6 /
/dev/sda7 /home

then you need to set /dev/sda2 as the boot partition with fdisk /dev/sda a 2
in the menu.lst of grub needs to be written: root (hd0,5)
