Yes you can. Go to Control Panel, Backup and Restore (Windows 7), create a System Image on a USB Hard Drive. 1) Remove all of your hard drives including NVMe drives and USB drives, 2) make sure you set in BIOS to boot into UEFI mode, 3) disable Secure boot in BIOS, 4) disable Fast Boot, 5) Enable Launch CSM, 6) under key management save the secure boot keys, 7) under PK Management delete key (delete only PK Management Key), 😎 prepare a flash drive for SSD7103 UEFI ROM package, 9) connect your SSD7103 with 2 to 4 NVMe drives to a PCIe x16 slot (it needs to be in a x16 slot if using 4 NVMe drives, 10) boot to the flash drive you created and flash the SSD7103 BIOS (FS0:\> SSD7103.nsh) if successful you will have a message "Passed". 11) Next create a bootable flash drive extract SSD7103_UEFI_v1.1.4_19_04_29 unzipped to the root of bootable flash drive, 12) your motherboard's BIOS post screen should display information about the NVMe SSD's, 13) boot to flash drive, 14) next enter the following command to enter the RAID creation utility: ArrayCreate.efi, 15) Next, create the array using the following command: create RAID0. This will create a RAID0 array using all of the SSD's, and configured for maximum capacity: 16) You can now exit the utility. Enter the following command: Exit. 17) Insert Windows install DVD or Flash Drive, 18) Install Windows, to Where do you want to install Windows, click load drivers browse to flash drive select Highpoint NVMe Controller, after loading driver return to the Where do you want to install Windows interface. The previous Legacy disks will now be recognized as a RAID array: create your partition size and install Windows, 19) once Windows installed connect your System Image Drive, then go into Backup and Restore (Windows 7) in Control Panel and restore from system image, 20) then install Highpoint RAID Management software.
You could also use a partition software (I use AOMEI Partition Assistant) clone your Windows drive before above steps 1 to 16, instead step 17) of booting to Windows Installation boot to your partition software, load driver, partition and format drive and clone new formatted drive, I did 2 different PC's one on my Asus R6EE with Windows install and the other one on my MSI with partition software, I think the first way Windows Install was better.
I would use clone disk only for testing and overclocking to see how everything runs. I strongly recommend steps 1 to 18 for a fresh install of Windows as not to carry over problems. Fresh install of Windows and reinstall all of your software would be your best option. By the way once you use your cloned Windows disk and want to do a fresh install you don't have to any of the above steps, only when you up date your BIOS you have to do steps 3, 4 and 5, plus reenable XMP and what ever overclock settings you changed. Good Luck
