Normally this'll work out just fine Neil, with a few notable exceptions
- dual booting from a single internal disk partitioned for multiple
operating systems is chief amongst these. It's unfortunately the most
common scenario however, and a dual Windows+Linux setup the most common
of those and can be quite fragile. Dual booting completely different OSs
from separate disks is much safer, or keeping a USB stick to run Linux
from.

That being said as long as you follow a couple of rules even dual
booting Windows+Linux from a single drive is perfectly fine you just
have to:

1: Always install Windows first
2: Linux/BSD/whatever is installed after Windows
3: Be prepared for Windows to destroy your bootloader during big updates
sometimes - you'll need a Linux live system to repair this and reinstall
GRUB occasionally

As ever, behaviour wildly differs between modern UEFI+GPT and legacy
BIOS+MBR systems: EFI based booting *should* be much more robust and
resistant to accidental trashing of boot loaders etc as operating
systems should be capable of writing their boot configurations to the
same FAT32 EFI partition without clobbering other coexisting entries.
I'm not going to lie to you though, in practice this just hasn't lived
up to it's promise (surprise surprise...) and modern UEFI systems can
actually be even more of a pain in the arse to configure and maintain
dualboot on than crappy old BIOS systems.

If in doubt, just buy another (cheap, preferably SSD) disk to experiment
on - you can never have enough fast disk storage lying around anyway.
