Not a problem, probably. I have at least one machine here dual booting which
has had 8.1 on, updated to 10 and dual booting with Debian on UEFI.

8.1 and 10 may already set up several Windows partitions.

Suggestion is to leave Windows as is and just create a single partition to install
Debian at the end of the disk.

This sounds very like a Bay Trail machine: http://wiki.debian.org/InstallingDebianOn/Acer/T100TA
may help here. You might need Debian multi-arch .iso to start with.

Switch off Secure Boot. You can leave UEFI on.

Clonezilla on a USB stick will work nicely.

Do that after installing Debian? Don't boot to Windows before installing Debian,

If Windows is installed first, then Debian, Debian should recognise that
there is a Windows install and install grub-efi correctly.

No, don't install Wheezy at all if: Jessie works from the outset with UEFI.
You may find that there is no legacy boot option in the BIOS if you are unlucky.

If you boot from Debian install media you can use the partitioning tools in the
installer to shrink an installed Windows partition. Put the empty space at the end
of the disk.
