I've used Macrium Reflect to create a rescue disk for my current laptop and I would like to use it to create a rescue usb for my new laptop. The new laptop doesn't have a dvd-burner. The laptop has a 250gb ssd, 177gb used. I only have a 1gb usb or a 1tb external hard drive, so I think I will have to buy a new usb.
I see three options in Macrium Reflect (Create image of selected disks/Create image of partitions required to backup and restore Windows/Create rescue media). What are the differences?
How much space will the usb need to have? Any other requirements of the usb stick? Does it matter what brand?
If I pick the rescue media wizard, there are options like iSCSI and Bitlocker and another option (something like WMI I believe). Should I just use default options?
