GRUB read error

Asked by Richard

I have just installed a 80gb hard drive from an existing 32bit PC into a new 64bit one. Before removing the drive I deleted all the partitions using Windows XP. Once the drive was in the 64bit I ran Ubuntu 7.10 live CD and installed the OS selecting 'use entire disk' partition option. However Ubuntu doesn't load - all I get is "GRUB read error." Is this because there is only one operating system? I am new to Linux so if anyone can help please make your answer as simple as possible. Thanks in advance.

Please try reinstalling again from the Live disc.

It may also have something to do with the 'master boot record' and that grub cant find it, but i doubt it, being a fresh install

Thanks for your help. I've reinstalled from the live cd but still get 'GRUB read error' on boot up. Could it be because I'm using the 32bit version of Ubuntu on a 64bit machine?

Turn off the 'auto' setting for DMA/UDMA mode for your hard drive in the BIOS and everything should then work.

That's fixed it! In my BIOS there are 3 choices for singleword dma and 3 for multiword. I went for the next one SWDMA0. I'm unfamiliar with what these settings actually do, so would you know if I am using the right one or should I use one of the others?

Thanks

Richard
