I have just installed Mandrake 9.0 on it's own 40Gb hard drive. I also have a 120 Gb VIA RAID array containing Windows XP. During the install I opted for GRUB as the bootloader and expected to be given the option to load XP or Mandrake when I rebooted. However, it just boots straight into XP as if Linux doesn't exist. I reinstalled Mandrake again to see if I had missed something important, but no luck. Anyone know what's going on please?

My system:

Pentium 4, 2.8Ghz, 512 Mb RAM
ASUS P4V800-X with VIA PT800 chipset, VT8237 RAID controller
2 x 80Gb Seagate SATA drives in RAID 0 configuration
1 x 40 Gb Maxtor drive

Yes, I just came across that thanks. I hope you manage to sort it out as well. It seems like quite a common problem, but I have yet to read a post where someone actually sorted it out (at least in language I could understand).
