However when I went to delete the other Recovery partition “disk0s5” it deleted the entire High Sierra Partition as well. I was able to delete “Apple_Boot Recovery HD 650.0 MB disk0s3” and merge the empty space with disk0s2. What the heck is going on here? Why is High Sierra destroying the Bootcamp partition or at the very least, why is it making it unbootable? This is an absolute nightmare that will not end. FAIL “No bootable device - insert boot disk and press every key” Select tools Tab “Make Legacy Bootable”, attempt to launch bootcamp from both Mac Partitions. Select tools Tab “Make EFI Bootable”, attempt to launch bootcamp from both Mac Partitions. Still FAIL “No bootable device - insert boot disk and press every key”

Attempt to launch Bootcamp from both Mac OS FAIL: “No bootable device - insert boot disk and press every key”.Launched Bootcamp Windows 7 - FAIL: “No bootable device - insert boot disk and press every key”.Launched Mountain Lion - Still working perfectly.Installed and tested High Sierra - Success.Partitioned 1TB of SSD on wifes MacBook for High Sierra - Success.Tested both Mountain Lion and Windows partitions on my wifes Macbook.Used Winclone & Target Disc Mode to migrate Windows 7 Bootcamp partition from my computer to my wife’s.Partitioned 100gb Bootcamp Partion - Success.After an entire week of this I surrendered and wiped the entire hard drive to start over. On my wifes computer, I’ve tried everything under the sun to get BootCamp installed properly and all roads lead to the familiar dead end “No bootable device - insert boot disk and press every key”. That’s fine, I can live with that and all OS work perfectly. I have to startup in Mountain Lion to get Bootcamp to show up as a startup disc. BootCamp doesn’t show up as a startup disc in Recovery or High Sierra.

On my computer I was able to install all OS with only one minor issue. The goal for both was to install a 2TB SSD drive and partition it with the 3 OS that we require for our AV production business:Īll of these OS are required for the various audio/video plugins we require so we must use these OS and the latest version of Winclone we can use is 7.3.4 My wife and I have identical mid 2012 Macbook 15’s. I’ve been working on this for a week to no avail.
