PLEASE, PLEASE
Install Linux Mint on an *External USB Drive* with GRUB on the external

It is much safer for a newbie than a 'dual single hard disc boot"

This preserves her Windows machine as Windows (It owns that internal
hard drive)
When she  boots with the *external USB hard Drive* plugged in she has an
independent Linux system.

I use this for all my old pupils! (Xubuntu for lite use) (Mint for some
depends on the RAM they have and age of machine)
Big advantage they preserve and can go back to their Windows machines if
wanted.

PS This is how I have ben running my own machines since about 2006.
Only the Vista era ones have had Windows removed and Linux installed to
internal drive, BUT they all have Knoppix USB key available as
alternative OS.


Honestly chief I wouldn't worry too much about that - whilst I get this method works well for you and in certain cases can be a good stopgap solution we've moved on a long way from external USB disks being a good idea, let alone preferred.

All the software in question is a lot more mature now, even Windows (stop laughing there at the back). The bad old days of stuff randomly clobbering each others bootloaders is well and truly over and UEFI firmware doesn't care about such trivial things anyway: it retains previous bootloader entries and doesn't rely on primitive stuff like ye olden days.

Modern Linux has spanking new safe NTFS drivers in kernel to manipulate Windows drives and Windows has safe drivers for Ext4 so you can even monkey about with the "other" operating system partitions from the "foreign" one without issues.

All booting from an external USB drive will get you is a more fragile bootloader setup and the unlucky OS hosted on the USB drive running at an absolutely glacial rate compared to the one hosted internally on the SSD. That speed difference alone will be at least an order of magnitude and even without any other factors is an absolute deal breaker for anyone with a SSD equipped computer. Most laptops now have NVME which will make the difference more like two orders of magnitude!

That being said different solutions obviously work for different people: I'm not saying don't do what you're doing, just that it's no longer really the standard response to say "Dual Booting Linux and Windows: DON'T DO IT". Nah, it's absolutely fine if that's how someone wants to roll.

I suspect that all your sample machines are much, much older and slower PCs right? If they're all ancient BIOS laptops with mechanical hard drives then the speed delta between booting an internal OS of the disk and booting an OS off an external USB flashdrive would be vastly smaller: probably even comparable.

On any vaguely modern system with a SSD it'd be madness to leave that performance on the table and boot from a crappy USB drive.

I have super modern laptops coming in that are USB3.2 and Thunderbolt equipped - at that level we're talking 20 or 40Gbps duplex at which point external boot drives become viable again and rival the internal NVMEs for throughput.

Anyway what I'm saying is don't fear the dualboot basically ¯\_(ツ)_/¯

My system dual boots Windows 7 and Linux Mint 20.2. Mint is on an internal SSD and Windows on a regular HDD. Two OSes just means Windows goes on first and then choose 'other' in the partitioning options aand tell Linux to use the bit Windows isn't.
