Dualbooting setups are usually fickle thanks to Windows and Linux using two different programs (called bootloaders) to start themselves. If one updates and becomes incompatible the other, you may not be able to (easily) boot into one of your operating systems.

This has gotten much better since the large-scale introduction of UEFI (required by Microsoft for device certification since Windows 8). With UEFI, the boot loaders are installed in parallel, and generally don't mess with each other except for possibly changing which one is the default (and when this happens, the vast majority of UEFI firmwares allow you to choose from any of the installed bootloaders by holding a key at startup). It is a great improvement over the BIOS days, when you got one 512 byte master boot record per drive, and OSes would just clobber it.

On UEFI systems, you typically want to have only one EFI System Partition (where all the bootloaders live), even if the operating systems themselves live on separate disks.

Now, if only Windows would stop setting the hardware clock to local time...
