Cloning a Windows installation (RAID 0) to single SSD (non-RAID) fails

Angry,

Is your machine booted via UEFI? Your blue screen screenshot looks like what would be expected when the boot order is wrong in your bios. Boot the PC and enter the bios. Look for the Advanced tab or section. In the Advanced screens look for Boot. Select Boot and look for Boot order. In boot order if your computer boots via UEFI make sure that the first device in the boot order list is Windows Boot Manager. If your machine does not boot via UEFI then make sure that new disk is first in the boot order list.

Save and exit the bios and see if it boots normally.

Typically cloning of a raid array to a single disk is not the best way to do a migration.

Hi Railtech,

Yes - the machine is using UEFI/GPT. I think you're right in that it's not finding the boot partition, but I have no idea how to troubleshoot that. Presumably the hidden System partition contains the /boot folder that points to the C: drive, but following the clone to the new SSD this is now pointing to the wrong drive. Trying to use the Macrium Boot fixer hasn't solved it. Neither has switching the mode for the drive from RAID to AHCI. Bit stumped by this really....

Best wishes,

Jon

With MR Cloning or Restoring an image is the same result with RAID 0, however, I wouldn't try to clone since having the image prevents any chance of losing any data or bootability. Since nothing is changed in the BIOS The OP can replace his 2 disk raid Array disk back in the computer and carry on. Should any issues develop with the Image Restore? As stated earlier the RAID 0 is set up by the motherboard prior to windows booting For MR to restore to a 2 disk Array that Array would have to be set up Prior to the Clone or Image Restore otherwise it going to restore to a single Disk/SSD

Hi ClintLGM (& everyone else who's chipped in)

Thanks for this. Can I check what (I think) you are suggesting...I should make a disk image with MR to e.g. an external disk. Then pull the RAID-0 array, attach the new disk and leave the mode as RAID (for now). Then I could boot from the MR recovery USB and restore from the external disk to the new SSD? If all goes well I should then be able to boot - and follow the steps necessary to switch the drive over to AHCI??

If you could check my thinking on this that would be really helpful....

Best wishes,

Jon

First thing is to check your boot order in the bios as I described in the post you quoted.

what is the output of bcdedit?

I went through a very similar procedure. I got an MSI laptop that came with 2x256GB RAID 0 SSDs and I broke the RAID0 and went through something very similar. You have to manage your boot entries with bcdedit and make sure that's OK.

Sorry to be a dufus, but can you point me in the right direction for how to check on this? I'll also get back with the boot order for Railtech asap....

Have you booted into a recovery CD/Flash?

You need a DOS prompt to run the bcdedit command. Where are you now?

Get a flash drive, 16gb in size download this rescue disk here:

Windows 10 Recovery Tools - Bootable Rescue Disk - Windows 10 Forums

then download flash drive image maker called Rufus and create a bootable USB flash drive.

then boot off that drive and start a dos prompt.

type in:

bcdedit

Hey Jon, hope this finds you well. What was the solution in the End. I am faced with the same issue. I have 2x SSDs in RAID0 and want to switch to single SDD with Windows 10. Please let me know, what needs to be done.

kind regards
