From System Backup to empty new drive

[Vince]

I've done this many times... no issues, BUT, since no mention of testing that Emergency Disk (USB stick), I would sure do that first. 

Thanks for your help @Froggie,

The stick boots ok and Hasleo starts ok on it, but data on it is just 610MB, thinking Hasleo's USB Boot stick fetches PE components it needs from active System Disk which would not be available  if it is replaced by an empty disk. Could be those PE components are only needed for creating the bootable Emergency disk and if the disk boots correctly not needed anymore.
Could you check if your Emergency boot stick also contains appr. 610 MB?
Thanks!
