Just Re Checked & yes you are absolutely correct as it upgrades to 5840 Beta via a macrium reflect patch of about 200 plus MB in size downloaded at %temp% directory of OS. But why they havent released that beta update n why just a patch download via reflect UI.
key to nothing leaves as its surely your boot system partition of windows macrium you recognize it in unallocated but it exists especially not touch it otherwise windows will not start any more error bcd blue screen with error 0xc00000 ..... or worse
I don't think so, because I remember it being there BEFORE the installation of Win 7. I assumed that the install media would wipe and format the whole disk before the actual installation, but afterwards I saw it was still there. Also: it is to the left of the windows partition, cannot be accessed by macrium and only be united with the windows partition if it is on the right side of it... ?
Its your boot partition even if you formatted the disk windows 7 would have recreated it .Make sure to have rescue media up to date your going to have to do a restore.
