sanboot and windows 7 iso

[erwan.l]

Hi There,

See below my script.
I can boot a winpe.iso image with sanboot : ok.
I can boot a winpe.wim image with wimboot : ok.
I can boot a pmagic.iso image with memdisk : ok.

but I cannot boot a win7.iso with sanboot.
I can actually boot up to the windows wizard where i should a disk to install to but then the wizard complains about a missing cd/dvd driver.
Any idea why?

side note : i have also posted about a all in one pxe server i made to help me boot different scenarios : http://reboot.pro/topic/18488-all-in-one...?p=171734.

Thanks for your help,
Erwan
