partitioning a RAID 0 drive

[Roy Lowrance]

Thanks Liam.

However, my Windows system became corrupt and I had to "recover" which means
starting over on the Windows side. So I decided to experiment with
partitioning anyway.

So I recovered, which reinstalls Windows and reformats the RAID0.

Once recovered, I asked Windows why was on the disk. The answer was
System 100 MB NTSF
OS C: almost 3 2 TB NTFS
HP_RECOVERY(D:) 11.65 GB NTFS.

I asked Windows to shrink C: to half its side leaving me with
System 100 MB NTSF
OS C: 927.18 GB NTFS
free space 924.09 GB unallocated
HP_RECOVERY(D:) 11.65 GB NTFS.

I rebooted and Windows appears to start.

I then rebooted from the Ubuntu-64 install disk. The install ran for a while
and near its end, I got this message:
executing'grub-install/dev/sda' failed
this is a fatal error

I am given choices
- choose a different device to install the bootloader on. The choices are
  /dev/mapper/isw_dgijegbaff_RAIDVOL Linux device-mapper (striped) (2.0 TB)
  /dev/mapper/isw_dgijegbaff_RAIDVOL1 Windows 7 (loader)
  /dev/mapper/isw_dgijegbaff_RAIDVOL2 Windows 7 (loader)
  /dev/mapper/isw_dgijegbaff_RAIDVOL-1
  /dev/mapper/isw_dgijegbaff_RAIDVOL3 Windows Vista (loader)
- continue without a boot loader
- cancel the installation

I assume I want a bootloader. Since I don't want to wipe out Windows, do I
put it on RAIDVOL-1?

I let the Ubuntu installer install onto the largest free partition. Perhaps
I want a different choice earlier in the install process.
