installing 11.1 at MSI WIND w/o DVD - got problems with YAST

I downloaded 11.1 DVD image from my Windows pre-installed, run the LOCAL setup .exe file, made my disk c: linux bootable, rebooted.
I’ve set up the path to my .iso file (in my case it’s /dev/sda5/suse/openSUSE11.1-DVD-i586.iso. I hoped that i can relax and enjoy the ride because YAST started.

But when YAST went to “Init REPO’s” - it told me “failed to create repo from url : ‘iso=openSUSE-11.1-DVD-i586.iso&url=hd:///suse/?device=dev/sda5&filesystem=auto’
could not mount iso:///?iso=openSUSE-11.1-DVD-i586.iso&url=hd:///device=dev/sda5&filesystem=auto”

I’ve tried to put NTFS, NTFS3G in FILESYSTEM tab, tried different pathes, but nothing helped.

By the way it sees my disk as WDC WD1600BEVT-2 (/dev/sda5)

Could somebody help me? i do not want to buy external CDROM/DVDROM only for loading OpenSUSE…
