I have had Ubuntu 11.10 installed on my computer on one hard disk. On another disk, there is Windows 8 Consumer Preview. I've been able to dual-boot with my BIOS's HDD selector. When I updated my Ubuntu 11.10 to 12.04, it included the new version of GRUB, which had an entry for Windows 8, as expected.
However, whenever I try to boot into Windows 8, I can see the fish for a second or two and then a few lines of error code as follows:
Your computer needs to restart. Please hold down the power button. Error code: 0x00000050 Parameters: 0xFFFFFAB006800000 0X0000000000000000 0XFFFFF801D09B6C90 0X0000000000000002
Can anyone help me chainload the Windows MBR to GRUB correctly to avoid a boot problem, or suggest a new bootloader to replace (or run along side of) GRUB so I can boot Windows 8 without problems?
