If you think that is difficult then don't try a dual-boot on a non-EFI system with Ubuntu 12.04 (Precise Pangolin) and Win7 both on software RAID. Win7 requires Dynamic Volumes for software RAID and repartitions the drive as GPT instead of MS-DOS. I ended up with a MS-DOS partition layout with Win7 non-RAID and Ubuntu using software RAID. I'm not sure why that even worked. <div class="gmail_extra"> <div class="gmail_quote">On Thu, Nov 15, 2012 at 8:10 PM, Brian Brodsky <<a href="mailto:brianbrodsky@ameritech.net" target="_blank">brianbrodsky@ameritech.net</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I decided to try the new Ubuntu 12.10 on my laptop. I had an old version of Ubuntu installed in a separate partition that I had setup as a dual boot with Windows 7, which worked fine. After I upgraded and was only able to boot Ubuntu. When I tried to boot to windows I got the following error: A disk read error occurred Press Ctrl+Alt+Del to restart.

I downloaded the 64 bit windows recovery disk and ran bootrec /fixboot and bootrec /fixmbr. This fixed my windows but grub no longer booted.

This got grub and Ubuntu back but my original problem of not being able to boot to windows was back. After fixing windows I am able to boot to ubuntu by booting off a super grub cd.

Does anybody have any suggestions on what I can do to create a dual boot system with windows 7 and ubuntu 12.10?
