My computer is running windows 7 on a software raid1 (ntfs obviously) partition. I would like to reduce the size of the partition (currently the on whole disk) to install a raid0 (or 1 I don't know yet) with a linux distribution.

Is there any precaution to take before resizing (I know I need to back up precious data) with gparted ? Is gparted able to take the raid1 into account and resize it properly ? Otherwise, what is the procedure to still be able to boot on the windows partition (and preserve raid) ?

I can provide further details if required. Thans for any answer !

Is the software RAID managed by Windows? If so can you shrink the volume on the Windows side first? – Paul Jan 16 '12 at 23:19

software raid is managed by intel matrix storage console – kamaradclimber Jan 17 '12 at 11:05

I would break the mirror, resize and remake the mirror, just to keep things as simple as possible. I agree, backing up/imaging is always a smart thing to do when modifying partitions.
