Purchased Winclone 9 to transfer from internal installation to external SSD.
iMac 2020 27", Big Sur installed
External drive - 2TB PNY CS3030 NVME installed in TB3 enclosure (JHL6340 controller)
Partitioned 500GB for boot camp
Tried all of the advice on this forum with no luck.
- Driver injection via Winclone Tools
- Modified Windows registry
Getting the same error message with BSOD: INACCESSIBLE_BOOT_DEVICE
Please advise what to try next.
