My new desktop has the following configuration (1 SSD with windows 7 installed) and a 2TB pair of Raid 1 disks.
Windows is installed on the SSD (120Gb) which includes a boot partition.
I have split the 2TB "raid-1) disk into 3 partitions (large NTFS partition), and 2 smaller partitions for Ubuntu (swap & Ext4)
I installed Ubuntu (or I think I have) installed Ubuntu on the two partitions and everything seems to be there, but I do not get a the GRUB 2 boot manual, and the installation ubuntu does not seem to detect windows 7 presence and I do not get the prompt at the end of the installation to ask where I would like to store the boot. Indeed, the only option I get for defining the boot option is on the raid disks, not on the SSD.
I have tried to resolve the problem using Boot-repair-disk and it hangs on the line "sudo chroot "/mnt/boot-sav/mapper/**" apt-get purge -y -force-yes grub*-common shim-signed linux-signed*.
