(Edited to add Win 8.1 info) Possibly I'm missing something very simple and obvious here but I've tried this 6 times now in various ways and obviously I don't know as much as I thought I did, and I know nothing about UEFI.I've searched the forums and tried various things without results and I hope someone can help, but I'm not convinced the Paragon documentation is very good. I have a new Asus G750 with Win8 Pro x64 which came with a 256GB SSD and a 512GB hard drive. Since it arrived I updated the Win 8 to 8.1 without issues. I wanted to change the drives to two 512GB SSDs in raid 0 configuration. I bought Paragon Hard Disk Manager 12 Suite (for 3 users), based on recommendations I read, and downloaded and installed the following as per the email I was sent: Component Paragon Hard Disk Manager 12 Suite - Windows Installation Package Component Paragon Hard Disk Manager 12 Suite - Boot Media Builder installation package Component Paragon Hard Disk Manager 12 Suite - WinPE Recovery Media Builder Serial protected (64bit) and the documentation. Once installed I ran the Backup -> Smart Backup -> and selected the entire SSD disk to go to my network drive. I then made two USB recovery media, one with the Burn Recovery Media option in the Suite, and a second one using standalone WinPE Recovery Media Builder for which I had to download WAIK from Microsoft and also added the mount for the network drive. Then I changed out both drives that came with the computer and installed two new Samsung 840 Pro Series 512GB SSDs. When it booted I went into the setup utility (BIOS) and set the disks to Raid 0, turned off Secure Boot and then let it restart and in the Intel Storage Manager (CTRL+I when booting) created a new raid volume (screen image). I rebooted using the WinPE Recovery USB and did a complete restore of the original GPT image to the new raid disk, with the 'Switch EFI to boot from destionation drive' and everything has seemed to complete successfully every single time but no matter what I try I can not get the restored disk to boot. This is what the raid disk shows the current structure after the last time I restored: Image. I have no clue why there are so many small partitions on the disk; presumably some are from Asus for restoring (no documentation there) and some are Windows 8.1 but I don't know. I have redone the Restore with booting from UEFI: USB Drive, and from USB Drive without the UEFI and tried all the settings I can imagine without success. I have undone the raid array and restored to two separate SSD drives. I have done a restore with only one SSD in the computer. I have run the Boot Corrector Tools and tried the Windows Installation to Correct, Correct Boot Parameters (boot.ini, BCD), and the Correct EFI Boot Parameters without success. As a side note when I try to boot from the other USB created in Hard Disk Manager there is no UEFI: USB option in the boot list, and when it shows me the Normal, Safe, Low Graphics, Find OS menu I get the following results: Normal: just reboots and returns to the same menu Safe: tries to boot and freezes during "Loading boot sector... booting..." Low-Graphics: tries to boot and freezes during "Loading boot sector... booting..." Find O/S: screen blanks and returns to the same menu but without the Find O/S option And lastly, I was going to give up and reinstall the original SSD and hard disk, but found that after the weekend my son took the SSD back to university with him and installed it as a new drive in his computer, so I can't even revert to what I had originally. Unless I can solve this I think I may have to go out and buy a new Windows 8 and do a fresh install and then try to restore just the data files. Any and all help would be much appreciated.
