Dual-boot iAtkos S3 v2 and Windows 7 Ultimate

[:JJ:]

Hi,

I'm trying to dual-boot windows 7 and iAtkos s3 v2 together, without having to wipe my existing windows installation off my system.

I've tried installing iAtkos s3 v2 on its own and it works perfectly, but then the windows partition couldn't boot up - it said there was no BOOTMGR.

I've tried using EasyBCD 2.0 and Chameleon boot managers, but I'm not quite sure how to get them to work.

I want to have both Operating Systems on one hard drive, but I do have a second hard drive, although I'm not sure how to dual-boot of seperate hard drives. Both hard drives are MBR.

EDIT: my Windows 7 partition is NTFS format

I'm looking to do the same, I don't want to start the installation before I can make sure I can boot back up to my Win7 installation though. Anyone could give us a hand with this?
