[Mageia-discuss] grub load failure

[e-letter]

Readers,

A PC previously using mandriva2008, tried to install mageia1 livecd
gnome (formatting only / and /boot partitions, leaving /home
unchanged), but fails to boot displaying the following error:

grub loading stage1.5

error15

Tried to boot the livecd (i.e. no install) but performance is very
slow, probably because memory is only 192mb (!).

Any ideas how to solve this problem?
