New board, 2 hard drives with win working 10 install - 1 SATA, 1 M.2 Cloned from Sata BIOS reports no boot device but can see both of them, together or separate. I've disabled TPM and UEFI still cannot boot to either device. Looking for a solution to utilize my cloned drive. |

cloned drive converted to GPT Shows up as a windows drive in boot order (same as before converting to GPT). |

Check my thread I posted to today. I had the same issue and it was the old HDD was a MBR format and not a GPT format. I didn't find a way to recover the data, though it's supposed to be possible by running a conversion program 'mbr2gpt.exe'. See this link: https://scottiestech.info/2017/11/12/convert-your-windows-10-boot-drive-from-mbr-to-gpt/" rel="nofollow - https://scottiestech.info/2017/11/12/convert-your-windows-10-boot-drive-from-mbr-to-gpt/ It didn't work for me, but maybe it will for you. Good luck, Gary -- |

It sounds like you're facing a classic boot order issue after cloning. Have you checked your BIOS settings to ensure the M.2 drive (the cloned one) is explicitly prioritized as the primary boot device? Sometimes the system defaults to trying the SATA first, even though the M.2 might be the drive you want. Makes me think of customizing my desktop! Good luck finding a solution. |

That's a tricky situation! It sounds like you've covered the usual suspects. Sometimes, even with cloned drives, the BIOS settings can be finicky. I had a similar issue once, and it turned out I needed to specifically select the drive as the boot override in the BIOS every time. ------------- https://snowrider3dd.github.io" rel="nofollow - Snow Rider 3D |
