Hi Tim,
Thought I’d surface this topic from our previous thread.
I’v been unsuccessful at moving my Bootcamp partition to an external SSD (Samsung T7).
To recap:
- New iMac running Catalina 10.15.7
- Bootcamp installed successfully on internal Bootcamp partition
- I used Winclone’s WIM mode to create an image of the working Bootcamp partition
- I restored the image to a Samsung T7 SSD, freshly formatted as GUID, 1 partition, exFat
- Restoration completed successfully
- SIP is off and external boot devices are allowed
- When I boot from the Samsung T7, it shows the 4 pane “window” with a wait circle, then reboots to macOS after a bit.
- Booting into Safe Mode gave me an sihost.exe error dialog: sihost.exe - System Warning, Unknown-Hard Error with an OK button. Clicking OK gave me a black screen with a mouse pointer and a flashing wait circle. I waited 10+ minute then rebooted.
Any ideas?
Two additional questions I’m hoping someone can answer:
- Is there a secret to getting into safe mode while booting? I tried F8 and F5 without success.
- Is there a way to choose an external boot device as the default startup device in macOS? I am not presented with the external drive from the startup disk panel in system preferences, despite the drive being attached, mounted and visible in Finder.
Thanks,
Steve
