Get a portable, USB CD drive.
 
I picked one up recently for about $40.
 
 

Yep, an external DVD/RW will work perfectly...

I have not tried what you describe. One would hope that a disk image made with a portable installation of Acronis would work, but remember, that the standard Acronis image is not just a copy of the drive, it is "smart" in that it decides what is important and what to save with the image. That is an advantage in reducing image size but potentially problematic if it decides that something is important in Vista but not in Win 10. If I were going to try this I would use the sector copy option which will reproduce the "empty" sectors i e. a forensic image, but that will add a lot of time and size to the backup. Or just use Windows imaging, or Macrium Reflect Free (or Home if you want to spend $). Or use your old version of Acronis and then try to restore it to the same drive. Everyone says that the only way to test an image restore is to actually run a restore, and everyone neglects to mention that doing an actual restore to the same drive will destroy the installation you just imaged, so if it fails you have shot yourself in the foot. Unless you have a spare identical drive to restore to that "test" is impractical.

You are fishing in the wrong lake for the answer you need. Try googling "windows 10" site: forum.acronis.com.

>Will Acronis True Image 2013 make an image of all of Windows 10's hidden partition areas?
Depends on whether you are backing up a partition or the whole drive.
A whole drive backup should back all partitions even hidden ones.
Hidden partitions may have naught to do with Windows 10, if you bought your PC with a OS chances are the vendor has a hidden rescue partition on the boot drive.
If you want to see what Acronis is excluding check the Exclusion settings.
 
Be aware that if you use Chrome - newer versions of Acronis by default does not save your browser settings, bookmarks, history, etc.
So if you use the browser to save passwords or you do a lot of bookmarking you might not be happy if you need to restore a system.
 
Note: I have not used Acronis 2013 to backup and restore a Windows 10 system.
So I can't tell you for certain if it can restore a Windows 10 backup or if 'support for Windows 10' is a marketing move to get you to purchase an Acronis upgrade.

The main files I exclude are the Window's swap file and the hybernation file: pagefile.sys and hiberfil.sys
These can be huge and the system will recreate both on first boot if needed.
 
One of then newer features Acronis offers (for a fee) is cloud backup.
Unless you've got phenomenal internet upload speed it's worthless on an active system - took weeks to backup my 2 terabyte laptop and I'm not even sure the backup is viable because of the constant updates and file changes that were happening while the backup was taking place.

Personally, I have hibernation OFF and the swapfile is on a different drive than my boot drive.
But this is good advice for most people.
I also point swapfile.sys to a different drive.
 
Most people should be able to store a full system image in a small, fast USB drive.
 
My backups take only about 10 -15 minutes (for the system drive image to a Supersonic Magnum USB 3 Flash Drive) - faster than a disk backup. I'm backing up as I write this and getting 1GB backed up every 7 or 8 seconds.
The system drive file space used is pretty big - 105 GB - the backup image is 70GB with default compression.
Backup with verify is under 30 minutes.
 
I have not had to restore Windows 10, but I did restore Windows 8.1 once in about 10 minutes or so. I forget the exact time, but it was fast.
