Cloned SSD from Raid 0 won't boot

Hello!

We have a slow desktop at work set in a RAID 0 setting. I used Macrium Free to clone the RAID HDDs to a SSD. When I try to boot with only the SSD, it doesn't detect a drive.

My RAID drives are plugged into a RAID card, and it shipped that way from Dell. I tried plugging the SSD directly into the SATA 0 port on the mobo, but it doesn't detect it. When accessing the BIOS, sometimes it does detect it, but I can't boot from it.

I tried replugging the RAID HDDs back but now it doesn't boot at all. Through some kind of loophole I managed to access the settings of the RAID card, but it doesn't detect the RAID drives.

I tried changing the settings in the BIOS from AHCI to ATA to disabled to get the SSD to boot but still no result.

Now, can I plug the single SSD into the RAID card and get it to boot? If not, how can I bypass the RAID settings to get the SSD to boot? Or completely random thought, can I get the SSD to boot from the USB 3.0 cable adapter?

I have no idea how to make this work at this point...

The computer is running Windows 7 Pro. There's absolutely nothing on the RAID card indicating a model of some kind, it's just written SAS on the side. The desktop is a Dell workstation, I'll check the exact model tomorrow at work (though it was a custom built from Dell)

Some questions? How many drives are in the system? Normally RAID 0 suggests 2 or more drives merged together to make a single larger capacity drive. Are you sure that this is not the case?

If it is a multiple drive RAID 0 that you are trying to move from larger hard drives to smaller SSDs, it is going to be trickier than just copying each drive, one at a time.

The safest method is to clone the striped hard drives to a single drive image, then switch the drives to have the SSDs connected to the system, set them up as a new RAID 0, then copy the backup image to the newly setup RAID, shrinking the volume in the process.

I removed the RAID and it is already set as AHCI. I can see the drive fine on another system, though I haven't tried booting from it (I'm a bit afraid of messing up another work computer, it went so smoothly on my desktop, but it wasn't in RAID) . It is running Windows 7 Pro, but I have no idea if it's formatted as MBR or GPT. How can I find this?

When you plug the SSD into another PC as an external drive, if you go to disk manager you can see on the L side if it is GPT or MBR.

The reason I ask if it is MBR or GPT is that sometimes cloning software does not do a good job of copying the MBR table so you have to use a windows installation disk, go into repair mode and it typically detects the MBR is bad and rewrites the MBR.
