Ok I'm having a rather annoying problem with my boot sequence. My laptop (HP Pavilion zv6000) is setup with a dual boot with Windows XP Pro and openSUSE v. 10; and booting with grub 1.5. The boot process works perfectly most of the time, however every 3rd or 4th boot fails. Here's what happens: I turn on the power, the HP splash screen loads, then the message "Loading Grub 1.5..." appears, and then the screen goes blank, reboots, and then the process repeats. I can fix it by inserting openSUSE disk 1, restoring the MBR, and re-installing the boot loader, but 3 or 4 boots latter...bam! Same problem. Does anyone know what the hell is going on?
