All drives are GPT so SHOULD boot UEFI, right? What I did yesterday, booting the Reflect restore media and repairing the boot sectors or whatever it does, now lets me boot from the clone from Windows Boot Menu, which, I think, is still coming from Windows 7 which was the original boot disk. All this because this is the 5th Win 10 upgrade/install, several have NOT gone well, and this one is my wife's main system so no (and I mean ZERO) room for error!!!įingers crossed, but still open to suggestions.Īs best I can tell I have I have the BIOS IS set to boot UEFI and Legacy (there is no CSM choice I can find), but I still can't boot by going into the BIOS and selecting to boot from it nor can I hit F12 on boot and select the clone drive and boot.

My goal here is to test upgrade the clone to Windows 10 and if successful, carry on, if not, back to the original Win 8.1 install, clone again and try again until I'm successful.

I MAY be able to boot from the clone from the UEFI boot menu now, too, time will tell. So now I can boot to the clone from there. Now when I boot I get the Windows Boot menu and it has 3 choices and not just 2 as before. I MAY be on my way to solving this! I booted from the Reflect restore media and fixed the boot on all the disks it saw. I've searched the web for UEFI info 'til I'm blue in the face and I can't figure it out. The original Windows boot is a GPT partition, so I imagine the clone is, too. But, alas, no matter what I've tried I can't get the clone to boot. Hook up the other drives and it boots back to Windows 8.1 fine, actually to the boot menu where I can choose Windows 8.1 or Windows 7. No matter what I've tried I can't get it to boot from the clone. I go into the BIOS and pick it, or the boot menu and pick it, and it says put in a disk with an operating system and reboot.

I shut down and disconnected all but the clone. I simply went into the BIOS and changed the boot device and WAL-LAH, done, worked dozens of times.īut.now I have a UEFI BIOS Gigabyte GA‑Z77X‑UD3H motherboard and I can't figure out how to boot from the clone. It's worked flawlessly every time, BUT, all my cases were with conventional BIOS computers. I've cloned many hard drives, for example, going from HDD to SSD, or SSD to larger SSD. I've been using Reflect for years, currently v6 4 licenses.
