I have a workstation that runs with a dual boot configuration(Ubuntu 9.04 and Win vista(home premium)). Yesterday I tried installing FreeBSD 9.0 over the Ubuntu partition. During the installation you are being prompt to choose between ada0 and ada1(I wanted to use the entire disk) -- win being on ada0 and ubuntu on ada1 so I choose the second option. The installer gives me an error at this point: "Operation cancelled -- pre-check failed".
After this step you are shown the layout of the partitions. In my case it was something like:
ada0 <#disk size> MBR ada0s1 <#disk size> ntfs <== win ada1 <#disk size> freebsd-boot ada1p1 64KB freebsd-boot ada1p2 <#disk size> freebsd-ufs / ada1p3 4.0GB freebsd-swap none da0 1.9GB BSD da0a 534MB freebsd-ufs
where da0 is a USB which contains the image of freebsd. The installation completes succesfully and the installer recommends rebooting the machine. When I reboot GRUB(installed with ubuntu) gets confused and throws the following error:
stage1.5 GRUB loading, please wait... Error 17
Is there an easy way(without resorting to format the drives and start all over again) to fix the boot entries?
