Installing Windows 7 64Bit on new SSD

Hey Guys,

i'm just getting a headdache. Windows installation doesn't find the installed ssd. I created a new VD in the PERC H310 menu and everything looks fine but windows setup doesn't see the device. Also not, when i choose the driver folder from the CD. I than downloaded some drivers from the dell homepage and choosed the windows setup to look on the usb device but... nothing works, windows doesn't "see" the ssd.

Changed vom ATA to AHCI, tested, back to ATA, tested ... how can i solve this problem?
