I have a dell PE R720 server with a H710P controller. I am trying to put an image on using a .wim file. When I boot using PXE I get the menu to select my image then when the diskpart tries to select and format the disk, it comes up with "there
are no fixed disks to show". I have added the controller drivers to the boot.wim but still have this issue. My image is Windows Server 2008 sp2. This has worked on many servers in the past but this is the first time using the H720P controller.
Resolved:
Thanks to Dell Support (thank you Paul) they directed me to the following site where I downloaded the winpe cab files needed for this particular controller card and other essential drivers. I then performed the following:
1. Extracted the cab files to c:\winpe_x86\drivers
2. Mounted boot.wim: Dism /mount-wim /wimfile:c:\boot.wim /index:1 /mountdir:c:\winpe_x86\mount
3. brought up a cmd prompt as Administrator and ran the following: dism /image:c:\winpe_x86\mount /add-driver /driver:c:winpe_x86\drivers /recurse
4. Committed change: dism /unmounts-wim /moundir:c:\winpe_x86\mount /commit
5. Copied the boot.wim back to my USB bootable drive sources\boot.wim
