comment How would I speed up a full disk dd?
@NickYeates That's not any of the commands given here. Your command because the redirection is performed by the shell that launches sudo, not by a process launched by sudo. You can use sudo sh -c 'cat linuxmint-17.3-cinnamon-64bit.iso >/dev/disk1' or <linuxmint-17.3-cinnamon-64bit.iso sudo tee /dev/disk1 >/dev/null

comment My processor is 64-bit - does that mean I need the amd64 image?
@Jelly No, they're called 32-bit, because virtual addresses are on 32 bits. Physical addresses (which are only used internally in some places in the kernel) use 64 bits. You can call it a “32-bit kernel with 64-bit physical addresses”, but by no means a “36-bit” or “64-bit kernel” — that would mean that pointers (i.e. virtual addresses) use 36 or 64 bits. The limit to 2^36 isn't due to the number of bits in pointers, but the number of bits spanned by MMU descriptors and on some buses; these have no reason to be powers of 2.

@Jelly PAE kernels (which includes the default kernel since 12.04) can access up to 64GB.

@Jelly I don't understand your comment. Were you reporting a typo? The only occurrence of “32-bit kernel” in my answer is correct. (Of course the sentence is also correct for a 64-bit kernel, but that isn't interesting.)

comment How do I skip the Grub menu on a dual-boot system?
@Clément Yes, it makes the time to press Shift short, but it's still possible.

comment How do I skip the Grub menu on a dual-boot system?
@Clément In your first comment, you wrote “after making these changes”… I don't understand what risk you're worried about. I don't describe any change to the way to access rescue mode in this answer. If you want to access rescue mode after making the change I describe in this answer, you can still do it (assuming you have physical access of course), you just have to press Shift at the right time during boot.

@Clément From wherever you've been making these changes. Presumably you booted from rescue media and chrooted into the system.

@Clément grub-set-default 1 (assuming that the rescue boot is the second entry in the file, check in /etc/grub/grub.cfg, numering starts at 0)

comment unable to access my user account
You can still access your system as long as you have physical access to it. But I'm guessing that having command line access won't help you much. We can help you repair your system, but you need to help us help you.

comment unable to access my user account
I'm sorry but your description of the problem does not give enough information to help you. It's going to be really difficult to diagnose that without seeing the machine, but we can try if you give us more information. What does this “display screen” look like? (Normally I'd ask for a screenshot, but you probably can't take a screenshot, so take a good-quality picture.) How were things different when you could access your account? What changed — what did you do between the time it last worked and the time it first didn't work?
